100% Gluten-Free Restaurants in Paris
Finding a place to eat gluten-free breakfast or lunch in Paris is very easy, but finding a place to have dinner is more difficult, as many of the restaurants and cafes listed aren’t open for dinner, unless indicated.
Chances are you and many others haven’t heard of Manicaretti, as they do not advertise themselves as being 100% gluten-free, though they are. With a restaurant name that translates to “little exquisite dish”, you can expect for every dish on the menu to be made to perfection.
Though the menu is seasonal and limited, each dish is made with love as the owner, Vittoria, takes great pride in her food and makes sure everything is fresh, organic, and made with amazing flavor.
From homemade gnocchi and lasagna to salads and homemade bread, you’ll find Manicaretti to be a mouth-watering treat on your trip.
60 Rue de Paradis, 75010 Paris, France | Website
The second you walk in the chef and owner will welcome you with open arms. From there you get the opportunity to enjoy a beautiful, healthy, organic, and plant-based meal in a relaxing little restaurant located on Cherche-Midi Street. I highly recommend getting the “no cheese” cake or the organic wine, both are exquisite. Overall, Apeti has a great atmosphere, friendly staff, and fresh and tasty food. Everything served there is vegan.
72 Rue du Cherche-Midi, 75006 Paris, France | Website
If you are looking for a place to enjoy a delicious homemade vegetarian meal, look no further than 3 Bio. Everything is beautifully presented, organic, vegetarian (vegan options available), and comes with a delicious herbal tea. As you wait for your food, you can actually see it being made as the kitchen is part of the dining area. Since this is a small bistro, the menu is limited and changes everyday. Be sure to plan accordingly if you want to eat here as they are only open from 12-3pm Monday-Friday.
44 Rue de Provence, 75009 Paris, France | Website
Located just a block away from the must-visit Canal Saint Martin is this vegan restaurant and shop that specialize in superfoods. Though the meals are simple, they are organic, seasonal, flavorful, and packed with superfoods. Having lunch at Sol Semilla will easily keep you feeling invigorated all day while you explore the City of Lights. Sol Semilla is also open for dinner from Wednesday to Saturday.
23 Rue des Vinaigriers, 75010 Paris, France | Website
You don’t need to go all the way to Thailand to enjoy delicious Thai food. You can have it in Paris. I know, who comes to Paris for Thai food? No one really, but when you’re tired of baguettes and croissants, head over to Kapunka for pad thai, green curry, and Thai iced tea. You will love every bite. The canteen is small and is often busy, so reservations are recommended.
51 Rue Saint-Sauveur, 75002 Paris, France | Website
Rice Trotters is a new-concept restaurant in Paris that serves dishes and desserts made exclusively of rice. From paella and prawns black rice to puff rice biscuits and rice pudding, Rice Trotters takes you on a tour around the world with each dish. If you are looking for something different, Rice Trotters is where you need to be.
Rice Trotters has two locations, one is a short walk from the Arc de Triomphe and the other is just minutes from the Louvre.
16 Rue Saint-Augustin, 75002 Paris | Website
From the owners of Kapunka Montorgueil comes Monsieur K, which also serves delicious Thai dishes in a stylish bistro. From the spring rolls to the mango sticky rice, you’ll enjoy every dish. What you might not enjoy is the bill, as it’s kind of expensive.
10 Rue Marie Stuart, 75002 Paris, France | Website
Mimi cave à manger
A visit to Mimi is like a visit back to Italy, and y’all know how much I love Italy. Everything is fresh, homemade, and tastes divine. The pasta, the cheese, the bread, the tiramisu, everything is just on point. So much so I had to come back for more. We actually found out that the chef is a celiac, and her ingredients actually come from Italy. Mimi is also a grocery store where you can stock up on quality pasta and olive oil from Italy. If you are looking for an authentic, fresh, mouth-watering Italian dish, then don’t pass up an opportunity to eat at Mimi!
105 Rue du Cherche-Midi, 75006 Paris, France | Website
As the first 100% gluten-free restaurant in Paris, this restaurant is well-known all over Paris and online. You can’t Google gluten-free Paris without this restaurant coming up, which means you simply can’t go to Paris without eating here.
Here you can enjoy a delicious, gourmet meal, fresh pastries, and baked bread including delicious gluten-free baguettes. Everything is organic, seasonal, and made daily. While the menu changes every day, you’ll be spoiled for choice. I recommend coming for brunch for the smoked salmon and if you can’t, get the signature beef burger and the apple pecan crumble. No worries, if you are vegan or dairy-free they have plenty of options available for you too.
NoGlu is one of the few restaurants on this list where you can have a 100% gluten-free dinner in Paris, so take note as dinner options are limited. NoGlu has two restaurants, with one location right across the street from their NoGlu bakery. Oh, and if you’re visiting NYC, there is a NoGlu location there too!

Vert Midi – CLOSED Vert Midi is a 100% gluten-free salad bar and restaurant in Paris offering a healthier spin on fast food. Everything on the menu is organic and seasonal. From salads and pastas to sandwiches and cold-pressed juices, Vert Midi has all the healthy goodies you can eat. You can customize your own salad and fresh juices, or enjoy one of the hot dishes like a focaccia sandwich from Chambelland bakery. 9 Rue aux Ours, 75003 Paris, France | Website
It’s not surprising that another Italian restaurant made it on this list. Though you can enjoy everything from salads to pasta, their best seller is without a doubt their pizzas. Though not the best pizza I’ve had, it’s still pretty good, especially since finding gluten-free pizza in Paris isn’t easy. A little warning though, the service can be slow, so be prepared to wait a while for your food, especially if you order pizza. Little Nonna is also open for dinner, so if you’re looking for a place to eat a 100% gluten-free dinner in Paris, this is a great choice.

100% Gluten-Free Bakeries in Paris
When it comes to gluten-free pastries, Paris wins everytime. I don’t know what they do, but they have mastered the art of gluten-free baking. So don’t you dare miss a chance to devour some of the best gluten-free pastries, croissants, and bread you’ll ever eat. To make sure that doesn’t happen, here are some of the best gluten-free bakeries in Paris.
These creative, elegant, melt-in-your-mouth pastries easily make you wonder if they’re really gluten-free. Part of their baked goods repertoire are the scrumptious gluten-free macaroons! Everything is made on site with the organic gluten-flour made by Chambelland. They also have many dairy-free options. If the prices weren’t so expensive, I am sure I would have gained an extra 20 pounds on my trip!
15 Rue Marie Stuart, 75002 Paris, France | Website
Helmut Newcake bakery is the bakery you would probably walk into and drool over all the beautiful pastries in the display window! But this time, you as a celiac can eat all of them! Finally! I am talking about to die for eclairs, better than the original gluten-free baguettes, flaky gluten-free croissants, and so much more. It’s safe to say Helmut specializes in making gluten-free versions of popular Parisian pastries like canelés taste better than the original ones.
And for my lactose-free friends, fear not. You can enjoy their pastries too, as they have plenty of dairy-free options. This gluten-free paradise also serves lunch, so if you want to enjoy a gluten-free lunch there or take it to go, you can. Word of advice, get there in the morning as they typically sell out of a lot of things by the evening.
28 Rue Vignon, 75009 Paris, France | Website
Run by a friendly owner who has a daughter with celiac disease, you know you’ll be taken care of. The pastries are not only gluten-free, but beautiful and flavorful. In this friendly and cozy tea room you can enjoy everything from fruit tarts, pain aux raisins, and chouquettes to muffins, madeleines, and homemade bread that doesn’t crumble! I recommend the fruit pies and the walnut cake, they’re finger-licking good. Lunch and savory goodies are also served at Onyriza.
38 Rue du Château d’Eau, 75010 Paris, France | Website
It’s not often you can indulge in delicious pastries that are both healthy and guilt-free, but at Foucade Paris you can, as they pride themselves on creating healthier but still delicious Parisian pastries. Whatever you eat here you won’t find anywhere else, as all their goodies are deliciously unique creations made with healthy ingredients. All their pastries are gluten, dye, refined sugar and lactose-free; they also limit common allergens and animal products. Foucade Paris serves savory dishes as well, which make it a great spot for a gluten-free brunch in Paris. Many of their dishes are vegetarian.
17 Rue Duphot, 75001 Paris, France | Website
If you love meringue/pavlova then you will love this place, since they specialize in it! La Meringaie makes the perfect meringue; they are crunchy and crisp on the outside but melt in your mouth when you bite into them. Topped with whipped cream and fresh and seasonal fruits, this is the perfect afternoon treat while you’re strolling through the streets of Paris.
21 Rue de Lévis, 75017 Paris, France | Website
Raw Cakes is the first raw, vegan pastry shop in Paris. They serve both raw and cooked food for lunch as well as fresh-pressed juices and delicious raw cakes. All the dishes are 100% vegan and gluten-free. However, some of their desserts contain oats that aren’t certified gluten-free! These desserts are not marked gluten-free because of this reason. Overall, RawCakes’ food has great flavor and you’ll receive very generous portions.
83 Rue Daguerre, 75014 Paris, France | Website
Yummy & Guiltfree
Since eating gluten-free waffles outside is such a rare occurrence, skipping this 100% gluten-free waffle bar would be a sin! With savory and sweet waffles that are light and fluffy, you’ll be in heaven and, as the shop name says, guilt-free 😉 They also serve many dairy-free options, if you need them. Yummy & Guiltfree has two locations in Paris, one not too far from Notre-Dame and another inside the Paris Gare de Lyon train station.
3 Rue du Temple, 75004 Paris, France | Website
La Belle Vie Sans Gluten
For the longest time this bakery only catered to hotels, restaurants, palaces, and big Parisian houses, but now they’ve opened their doors to the public 🙂 With a name that translates to “the beautiful life of gluten-free” and a pastry chef who comes from a long line of chefs, you can expect nothing but greatness in every bite of pastry or bread.
8 Rue Augereau, 75007 Paris, France | Website
Like every bakery on this list, Chambelland serves tasty pastries like cakes, muffins, and tarts, but I think everyone comes here for the bread and sandwiches. They’re light, yet deliciously crunchy focaccia bread is to die for. Actually, I think it’s safe to say they make the best gluten-free bread I have ever eaten! It might have to do with the fact that they mill and produce their own organic flours. Whatever they are doing, it’s working.
Chambelland also caters to other dietary needs, such as dairy-free and vegetarian. Chambelland was one of my favorite bakeries in Paris. Needless to say, if you are looking for an amazing gluten-free bread or sandwich in Paris, go to Chambelland.
14 Rue Ternaux, 75011 Paris, France | Website
Me (Mon Eclair) – CLOSED With the motto “par vous et pour vous” (for you and by you), Me (Mon Eclair) provides a unique pastry experience where you get to build your own eclair! From the base to the topping, you pick it all and they make it for you right before your eyes. Now that is a treat! 52 Rue des Acacias, 75017 Paris, France | Website
100% Gluten-Free Cafes in Paris
If you are on the hunt for a great gluten-free lunch in Paris or a place to try safe gluten-free crepes or galettes, then look no further than Biosphere Cafe. Being the first organic and gluten-free creperie in Paris, I knew this was going to be the spot to experience a 100% gluten-free crepe, and they did not disappoint. The caramel & ginger crepe and the macarons were delicious.
Beside crepes, they also serve pizza, quiches, salads, and more. If you are in Paris on a Sunday, I highly recommend going to their gluten-free brunch for a nice and relaxing meal, however, make sure to make a reservation. Lactose and egg-free options available.
47 Rue de Laborde, 75008 Paris, France | Website
Thank You My Deer
Just off the touristy path, you’ll find this little gem waiting to wow your taste buds. The small but delicious menu includes yummy bread and sandwiches, as well as great pastries and good coffee. Unlike most places in Paris, they are open early for breakfast and serve both lunch and brunch.
112 Rue Saint-Maur, 75011 Paris, France | Website
Bears and Raccoons
Bears and Raccoons is another popular gluten-free cafe that serves delicious sandwiches on awesome gluten-free bread. The bread is crispy on the outside and soft on the inside. As for the fillings, they’re plentiful and they don’t skimp on them either.
The scrumptious fan favorite, which I went with, is the “Grumpy Bear”, which is filled with coleslaw, pastrami, pickles, cheese, and rocket salad. But don’t feel like you have to have this one, as there are other sandwiches, like “Lumberjack” or “Sneaky Raccoon”, which are just as awesome. Bears and Raccoons also serves gluten-free beer, delicious cakes, brownies, cookies, and other pastries.
21 Rue Richard Lenoir, 75011 Paris, France | Website
La Guinguette d’Angèle- Le Take Away
In the heart of Paris, not too far from the Louvre, you’ll find this beautiful, gluten-free takeaway shop that serves delicious lunch boxes. They are not only full of flavor, but also healthy. Every dish is fresh, organic, seasonal, and vegetarian. No two meals eaten here will be the same, as the menu changes every day. If you are looking to treat your body and mind to a healthy and wholesome meal, don’t miss this 100% gluten-free corner on your gluten-free trip to Paris.
For a great Parisian experience, I highly recommend grabbing a lunchbox with a fresh juice and a dessert and heading to the nearby park. Or better yet, head to the Louvre for a nice gluten-free picnic in Paris. La Guinguette d’Angèle has two locations, one is the take-away shop mentioned above and the other is a small restaurant with a few tables. Vegan options are always available.
Various locations | Website
A few blocks from the famous Louvre is Maisie Cafe, the cafe everyone is calling the vegan HQ’s. This cute little restaurant is where to go if you’re looking for a healthy breakfast, a quick lunch, or cold-pressed juices and drinks. Everything from the soups to the focaccia (it’s Chambelland bread – so you know it’s good) is vegan, organic, and of course, gluten-free.
32 Rue du Mont Thabor, 75001 Paris, France | Website
Paleo Vingt et Un
Paleo Vingt et Un is the first paleo restaurant in Paris that serves 100% natural foods. That means no processed ingredients, no gluten, no refined sugar, and no lactose, just good ol’ natural food that is also organic. This cozy little restaurant, not too far from Place de la Bastille, serves a dishes based on the chef’s findings at the market and the season. But I am sure whatever he comes up with will be gluten-free and delicious, so no need to worry! Every day there are two set menus, one for meat eaters and another for vegan eaters. If clean eating is what you are looking for on your gluten-free Paris trip, I highly recommend Paleo Vingt et Un.
21 Rue Godefroy Cavaignac, 75011 Paris, France | Website
When it comes to unique and delicious gluten-free waffles in Paris, I vote for Cafe Mareva. Specializing in delicious, sweet potato based waffles that can be topped with either sweet or savory toppings like guacamole, egg, or bacon, you won’t want to miss this place on your gluten-free food tour in Paris.
Though most people, like myself, come for the waffles, they also serve smoothie bowls, quiche, soup, and heavenly pastries, like lemon tarts and brownies. The coffee and fresh juices are not to be missed either. Added bonus – everything on the menu is lactose-free and vegetarian friendly.
38 Rue du Faubourg du Temple, 75011 Paris, France | Website
Cairn Coffee Shop & Naturopathy
If you’re looking for a gluten-free meal near the Eiffel Tower, Cairn Coffee Shop & Naturopathy is the only option. This 100% gluten-free coffee shop has delicious gluten-free pastries accompanied by amazing coffee, cappuccino, and fresh detox juices. Their cookies and brownies are also unbelievably good. I highly recommend this slice of gluten-free heaven while on your way to the Eiffel Tower.
3 Rue Dupont des Loges, 75007 Paris, France | Website
Wild & the Moon
This popular, hipster vegan shop serves everything from cold-pressed juices, acai bowls, and salads to all-day breakfast meals and main dishes. Though on the expensive side, you know you’ll enjoy a healthy meal, as everything is organic, seasonal, fresh, and plant-based while being free from refined sugar, additives, chemicals, soy, dairy, and of course, gluten. With seven locations scattered around Paris, you won’t want to miss a chance to get your healthy food fix while exploring Paris.

Most of the dishes are vegan and lactose-free. There are three locations in Paris, Rue Amelot, CMG Sports Club, and Printemps.
Lemanja Paris Tapiocaria
Brazil lovers rejoice, as Brazil has finally arrived in Paris. This small restaurant serves up the delicious Brazilian street food snack, tapioca crepes, that can be stuffed with everything from vegetables, salmon, and pastrami to bananas, chocolate, and pineapples. The crepes are fantastic, but accompanied by the cheese balls (Pão de Queijo) and salad, you’ve got yourself an exquisite, yet not expensive, gluten-free meal in Paris. If you want to be transported back to Brazil, seriously stop by Lemanja Paris Tapiocaria.
12 Rue Dupetit-Thouars, 75003 Paris, France | Website
This small, warm and welcoming vegan haven is a small canteen-style restaurant in the Madeleine district. The food is simple, healthy, well-cooked, full of flavor, and responsibly priced. I recommend getting the ½ bowl (where you pick what you want in the bowl) with a soup, that way you get a taste of everything. Please note, they use oats in some of their dishes that may or may not be certified gluten-free.
41 Rue Godot de Mauroy, 75009 Paris, France | Website
This unique cafe in Montmartre is more than just a coffee shop. Besides selling excellent and organic coffee and gluten-free brunch, they are also an art gallery. If you are looking for a great place to enjoy specialty coffee while enjoying a great selection of gluten-free food, take the trip to Cassiopée Café.
21 Rue Custine, 75018 Paris, France | Website
While traveling through Italy I developed a “healthy” addiction to Grom gelato. It’s delicious, 100% natural, and best of all, it’s 100% gluten-free (at least in Italy and Paris). My go to flavors are almost always hazelnut, crema di grom, and torroncino. But the flavors are seasonal and constantly change, so I like to mix it up sometimes.
If you haven’t heard of Grom, it’s a popular Italian gelato chain that serves gluten-free gelato, milkshakes, sorbets, and more! Everything is made from real fruit and ingredients, so there are no additives, artificial coloring, or preservatives, just good ol’ traditional Italian gelato. Grom has 8 locations in Paris, including two at Disneyland Paris and another not too far from Notre-Dame.

Permanently Closed Gluten-Free Restaurants
