Eating at Papa Johns with celiac disease, IBS or food allergies

It depends on what you need to avoid, and Papa Johns sets out its limits plainly. As of October 2026, its US Allergen Guide says: "With most of our menu made fresh to order, we cannot guarantee that our products are completely free from common allergens because of the possibility of cross-contact within the kitchen." It also states that Papa Johns and its franchisees assume no responsibility for customers with food allergies.

Its Ingredients page adds: "Please note that all of our products may come into contact with wheat or dairy in our restaurants." So this guide doesn’t point to "safe" choices. It summarizes what Papa Johns’ own pages list, so you can see where gluten, milk, egg, soy and common FODMAP sources appear, and what to ask.

Papa Johns answers the main questions on its Gluten Free Crust FAQs page. As of October 2026:

• Celiac disease: Papa Johns "does not recommend pizzas with Papa Johns Ancient Grains Gluten-Free Crust for customers with Celiac Disease."
• Why: although the crust is gluten-free and Papa Johns says it employs procedures to prevent contact with gluten, "it is possible that a pizza with Papa John’s Ancient Grains Gluten-Free Crust is exposed to gluten during the ordinary preparation process."
• Ahead of the store: Papa Johns says the crust is prepared in a gluten-free environment ahead of reaching stores.
• Size and availability: it’s a personal-size pizza. Participation and availability vary, and it may not be offered at stadiums, arenas, airports and similar locations.
• Boxes: pizzas on the gluten-free crust are packed in the same boxes as the traditional crusts.
• Other gluten sources: besides the Original, Thin, NY Style and Epic Stuffed crusts, Papa Johns names its Chicken Poppers, Garlic Parmesan Sauce and the Italian Herb Seasoning packet.

The Celiac Disease Foundation notes that pizzerias offering gluten-free crusts sometimes don’t control for cross-contact with wheat-based dough, which matches what Papa Johns says about its own kitchens. Whether a shared kitchen is an acceptable risk is a decision to make with your gastroenterologist or dietitian. Our guide to gluten-free vs celiac-safe explains the difference.

This one surprises people. As of October 2026, Papa Johns’ Ingredients page lists the gluten-free crust as made with water, sorghum flour, modified rice starch, tapioca starch, teff flour, cage-free egg whites, whey powder, shortening flakes with soy lecithin, quinoa flour, amaranth flour, oil, yeast, sugar, brown flax seed, salt and xanthan gum, among other ingredients. It is labeled "Contains: Milk, Egg, Soy", and the allergen guide marks the same three allergens.

So if you avoid gluten and also have a milk, egg or soy allergy, or need to limit lactose, the gluten-free crust may not suit you. That’s a good example of why every part of a pizza needs checking on its own.

These examples come from Papa Johns’ US Allergen Guide and Ingredients page. They describe what Papa Johns lists. They are not recommendations, and they can change.

The asterisk in Papa Johns’ chart means an item "may be produced/stored in a facility that utilizes that allergen." A separate triple asterisk means "may contain/produced on the same production lines." Both matter if you have an allergy. FARE explains that even tiny amounts of an allergen from cross-contact can cause a reaction.

Papa Johns’ ranch sauce also lists onion and garlic, and its BBQ sauce lists garlic, on the Ingredients page.

• Garlic: in the original pizza sauce, BBQ sauce, ranch and Alfredo sauce, according to the Ingredients page.
• Onion: as a topping, and dried onion in the Alfredo sauce and onion in the ranch.
• Wheat: in every crust except the gluten-free one, and in breadsticks, garlic knots and boneless wings.
• Lactose: in the cheese, Alfredo sauce and the gluten-free crust, which lists whey powder.

Monash lists garlic, onion, wheat-based breads and mushrooms among higher-FODMAP foods, and pineapple and green capsicum (bell pepper) among lower-FODMAP ones. Your own triggers and portion size matter most. See our guides to pizza with IBS, celiac disease and dairy and hidden garlic and onion.

1. Check the current Allergen Guide and Ingredients page for every part of the order: crust, sauce, cheese, toppings, dips and seasoning packets.
2. Order the change from the start in the app or online, rather than asking for something to be removed later.
3. Tell the store about an allergy or celiac disease, even when ordering online. Ask about shared utensils, pans and cutters.
4. Skip or check the extras. The seasoning packet and some dips carry their own allergens.
5. If you’re unsure, skip it. It’s fine to choose something simpler or eat elsewhere.
