Low FODMAP Pizza: How to Make and Order Pizza with IBS
Low FODMAP Pizza: How to Make and Order Pizza with IBS

Key Takeaways
- Pizza is not automatically off-limits with IBS — with smart choices, you can eat pizza safely
- The crust is the biggest variable: GF crust is safest; sourdough (long-fermented) is lower FODMAP than regular dough; thin crust means less wheat per slice
- Aged cheeses (mozzarella, Parmesan) are naturally low in lactose — pizza cheese is generally safe
- The FODMAP traps: garlic in the sauce, onion on the pizza, wheat in thick crusts
- Home-made pizza with GF crust and garlic-infused oil is the safest option
Ordering Pizza Out
Crust Selection
- ✅ Gluten-free crust: Many pizza chains now offer GF crust (Domino's, Papa John's, local pizzerias). Zero fructan concern. Check for cross-contamination if you have celiac disease.
- ⚠️ Thin crust: Less dough = lower fructan dose. 2 slices of thin crust may be tolerated.
- ⚠️ Sourdough pizza: Long sourdough fermentation (24+ hours) reduces fructan content by 60-90%. Traditional Neapolitan pizza uses long fermentation. Ask your pizzeria about fermentation time.
- ❌ Deep dish / stuffed crust: Maximum wheat per serving. Highest fructan load.
Sauce
- ✅ Olive oil base (white pizza): Skip the tomato sauce entirely. Brush the crust with garlic-infused olive oil. Zero FODMAP.
- ⚠️ Tomato sauce: Most pizza sauce contains garlic. In small amounts on a standard pizza, many IBS patients tolerate it. If highly sensitive, request light sauce or no sauce.
- ⚠️ Pesto: Store-bought pesto usually contains garlic. Ask if homemade (may or may not).
- ❌ BBQ sauce, ranch: Both typically contain garlic, onion, or HFCS.
Cheese
- ✅ Mozzarella: The pizza standard. Low lactose. Safe.
- ✅ Parmesan: Aged 12+ months. Virtually zero lactose. Safe.
- ✅ Feta: Low lactose. Safe in normal pizza amounts.
- ⚠️ Ricotta (on white pizza): Higher lactose than aged cheeses. Small amount may be tolerated.
Toppings
- ✅ Bell peppers, spinach, olives, tomato slices, jalapeños, pineapple (small amount), arugula, basil, mushrooms (canned, small amount)
- ✅ Chicken, bacon, ham, pepperoni, sausage (check for garlic)
- ❌ Onion (red, white, caramelized): High fructan. The most common pizza FODMAP trap.
- ❌ Garlic (roasted or raw): If there are visible garlic pieces on the pizza.
Homemade Low FODMAP Pizza (Best Option)
GF Pizza Dough
Use a GF pizza crust mix (Caputo Fioreglut, Bob's Red Mill GF, or store-bought premade GF crust). Follow package directions. Roll thin on parchment paper.
Low FODMAP Pizza Sauce
1 can (15 oz) crushed tomatoes + 2 tbsp garlic-infused olive oil + 1 tsp dried oregano + 1 tsp dried basil + 1/2 tsp salt + pinch of sugar. Simmer 10 minutes. No garlic cloves needed — the infused oil provides the garlic flavor profile.
Assembly
Spread sauce on crust. Top with shredded mozzarella. Add your safe toppings. Bake 450°F on a preheated pizza stone (or baking sheet) for 12-15 minutes. Finish with fresh basil and a drizzle of garlic-infused olive oil.
