Gluten-Free Pizza: What to Ask the Pizzeria

Published 26 October 2026 · 7 min read

A pizzeria can make gluten-free pizza from a gluten-free base, but with coeliac disease it also matters how the pizza is prepared and baked. Wheat flour hangs in the air of a pizzeria, and the oven, peel and cutter are often shared. So ask about the whole process, from preparation to slicing, not just the dough.

Why pizza is tricky with coeliac disease

A pizzeria is one of the hardest places for people with coeliac disease. The problem is not the pizza itself but the kitchen. Traditional pizzerias work with wheat flour: dough is kneaded, stretched and dusted, and the flour settles on surfaces, tools and in the air. A gluten-free base prepared in that environment can pick up gluten from its surroundings.

In the EU, food can be labelled "gluten-free" if it contains no more than 20 mg of gluten per kilogram (Commission Implementing Regulation (EU) No 828/2014). This also applies to non-prepacked food, including pizza in a restaurant. But the words "gluten-free pizza" on a menu do not tell you what precautions the kitchen actually takes. The difference between coeliac disease, allergy and intolerance is explained in Allergy, intolerance and coeliac disease.

What to ask

Dough and base

  • Where does the gluten-free base come from? It may be a ready-made par-baked base in separate packaging, or dough made in the same kitchen from gluten-free flour.
  • How is it stored? If it is stored openly next to wheat flour, cross-contamination can happen.
  • Does the dough contain only gluten-free ingredients? Some mixes contain, for example, oat flakes or thickeners. On oats, see also Oats and coeliac disease.

Flour in the air

  • Is the gluten-free pizza prepared separately from the wheat dough? Ideally on its own surface, cleaned before use.
  • Is flour being used at the same time and in the same space? When regular dough is stretched, flour is thrown into the air and can land on the gluten-free base.
  • Is the surface dusted with wheat flour? Some pizzerias use it on every peel.

Oven

  • Is the gluten-free pizza baked in the shared oven? Wheat flour and bits of dough stay on the oven floor and can stick to the bottom of the pizza.
  • Is it baked on a separate tray or mat? A tray or mat between the pizza and the oven floor reduces contact.
  • Are wheat pizzas in the oven at the same time? Some places bake gluten-free pizzas in a separate oven or at a separate time.

Peel, cutter and serving

  • Is there a separate peel? The wooden peel used to move regular pizzas holds on to flour and bits of dough.
  • Is there a separate cutter or knife? A shared cutter can transfer gluten to the gluten-free pizza.
  • Is it served on a clean plate? Check that the pizza has not been put down on a surface with wheat crumbs.

Toppings

Even a gluten-free base can be a problem because of the toppings.

Topping Why to ask
Tomato sauce may be thickened or seasoned with a ready-made mix
Cured meats and salami may contain binders or fillers with gluten
Cheese a shared bowl and shared spoon can transfer traces of gluten
Ready-made dressings and oils possible added gluten or seasoning
Garnishes added after baking breadcrumbs, croutons or wheat flour

In a pizzeria, cheese is often taken from a shared bowl by hand or with a spoon. If that utensil has previously touched wheat dough, gluten can be passed on.

Pizza at home and delivered pizza

With delivery, packaging adds to the risk in the kitchen: a gluten-free pizza may travel in a shared box or on the same mat as a regular one. When ordering through an app, ticking "gluten-free" is not enough. If you can, call and ask about the process. If you bake pizza at home from a ready-made gluten-free base, use a clean tray and a clean mat, not the ones used before for regular pizza.

How to choose a better pizzeria

No question can give you full certainty, but these signs help:

  1. The restaurant can explain its process without hesitation.
  2. It has separate utensils, trays and a cutter for gluten-free pizzas.
  3. The gluten-free pizza is made separately by someone who has washed their hands and changed gloves first.
  4. It states clearly what its "gluten-free" offer means (only free of gluten-containing ingredients, or also protected against cross-contamination).
  5. The process is described online, or confirmed by a phone call, so you can check it in advance.

If a pizzeria says it cannot rule out contamination, that is an honest answer. With coeliac disease, it is then up to you whether to order or look elsewhere. People with mild gluten sensitivity may have different needs from people with coeliac disease.

Questions for staff, in one place

Say so right at the start and make clear that it is coeliac disease. Then ask:

  1. What is the gluten-free base made of, and where is it stored?
  2. Is it prepared separately from the wheat dough?
  3. Is it baked in the shared oven, or on a separate tray?
  4. Do you use a separate peel and cutter?
  5. Have you checked the sauce, cured meats and cheese?
  6. Will the chef check this, or are you confirming from memory?

More on how to phrase questions is in How to ask about allergens in a restaurant.

How AvoiDino can help

In AvoiDino you set gluten as your allergen and filter dishes by allergen. It helps you find pizzas where gluten is not listed among the ingredients, but you can only check the preparation process with the staff. Treat the app as a way to narrow down your choices, not as a guarantee of safety.

Frequently asked questions

Is a gluten-free pizza from a pizzeria safe with coeliac disease?

Not always. It depends on whether the restaurant keeps preparation, baking and slicing separate from the wheat dough. Ask about the specific process.

Is it enough that the base is gluten-free?

Not always. Even a gluten-free base can come into contact with wheat flour in the air, in the oven or on the peel. The whole process matters, not just the dough.

Can I have a gluten-free pizza if it is baked in a shared oven?

It depends on how strictly you need to avoid gluten. With coeliac disease it is better if the pizza is baked on a separate tray or at a separate time. Talk to your doctor about the level of risk.

How can I check that a pizzeria can prepare gluten-free pizza?

Ask about the dough, oven, peel and cutter. A clear, specific answer from the chef is a good sign, not a quick "that's fine".

Can gluten come from the cured meats or sauce on a gluten-free pizza?

It can. Cured meats and ready-made sauces may contain binders or thickeners, so ask about the toppings too.
