Low FODMAP Grilled Pizza

Low FODMAP Grilled Pizza is gluten-free pizza made right on the grill. It is thin crusted, develops a nice char on the bottom and top (more on that later) and features varied, yet sparse, toppings. This is all about the grilled crust.

Grilled Pizza Sauce:

  • 1, 28- ounce (794 g) can of either whole peeled tomatoes in juice or purée, or puréed/crushed tomatoes
  • ½ teaspoon FreeFod Garlic Replacer
  • ½ teaspoon kosher salt
  • 1 tablespoon extra-virgin olive oil

Grilled Pizza Dough:

  • 2 ½ cups (363 g) low FODMAP gluten-free all-purpose flour, such as Bob’s Red Mill 1 to 1 Gluten Free Baking Flour, plus extra
  • ¼ cup (25 g) fine-ground white cornmeal
  • 1 tablespoon instant dry yeast
  • 1 ½ teaspoons salt
  • 1 teaspoon xanthan gum
  • Pinch sugar
  • 1 cup (240 ml) plus 3 tablespoons warm water, 120°F to 125°F (48°C to 52°C)
  • 1 tablespoon extra-virgin olive oil


  • 7- ounces (200 g) shredded Italian Fontina (about 2 cups)
  • ½ cup (50 g) ground Pecorino Romano
  • Low FODMAP Garlic-Infused Oil, made with olive oil
  • Fresh basil or other herbs


  1. Make The Sauce: If using whole canned tomatoes, put them through a food mill or pulse very briefly in blender just enough to break down. Take that tomato mixture, or the canned puréed/crushed tomatoes and pour into a pot. Whisk in the teaspoon FreeFod Garlic Replacer and salt until combined, then whisk in the oil. Bring to a simmer over low-medium heat and simmer, stirring often, until slightly thickened, about 5 minutes. Cool. Sauce made be made 3 days ahead and refrigerated in an airtight container.

  2. For Making Dough By Hand: Whisk together the flour, cornmeal, yeast, salt, xanthan gum and sugar in a large bowl to aerate and combine. Add the warm water and olive oil and begin to stir together with a sturdy wooden spoon until a wet dough forms, then beat vigorously until mixture looks like a thick, moist batter.

  3. For Making Dough With A Stand Mixer: Place the flour, cornmeal, yeast, salt, xanthan gum and sugar in stand mixer bowl fitted with flat paddle attachment and mix on low to aerate and combine. Add the warm water and olive oil and mix on low-medium speed until a wet dough forms, then turn speed up to medium to medium-high and beat until mixture looks like a thick, moist batter.

  4. Lightly coat a bowl or container with olive oil, scrape the dough into the receptacle and turn the dough around to coat with oil. Seal the bowl with plastic wrap, or snap on a cover to the container and place in a warm, draft-free area for 2 hours or until it has visibly risen. Punch down, cover, and allow to rise for another 45 minutes to an hour. Prep your toppings and get your grill ready at this time.
  5. Make a hot fire using hardwood charcoal with the coals piled up on one side of the grill. Ultimately the grill should be about 3 to 4-inches (7.5 cm to 10 cm) above the coals. When the coals have all turned ashen, you are ready to go.
  6. Take a small ball of dough and place it on a floured half-sheet pan. Press the dough out to a thin, even thickness using floured fingers and palms. You want to make it as thin as you can and still be able to pick it up without it falling apart. About 6 to 7-inches (15 cm to 17 cm) across is a good diameter. Go for a rounded shape, but it is perfectly fine if it is vaguely amoeba-like. The thinness is far more important than shape. Do not create a thicker rim.
  7. Pick the dough up with two hands and/or a broad metal spatula and swiftly but carefully transfer it to the hot side of the grill. Brush the top with Low FODMAP Garlic-Infused Oil. Within a minute or so the crust will puff up and charred grill marks will appear on the bottom of the crust. Flip the crust over with your tongs and drag it over to the cool side of the grill. Brush the crust with more garlic-infused olive oil.

  8. Sparingly dollop tomato sauce here and there, then lightly scatter Fontina cheese over the sauce, then add a light sprinkling of Romano. Do not try to cover the whole surface with tomato sauce and cheese. Use tongs to drag crust back over to the hot side. Use tongs to rotate the crust over the hot coals and monitor it closely. You want the cheese to melt and the bottom to develop nice char marks without burning. This part will take maybe 3 to 5 minutes, but you cannot walk away! Once done, use tongs again to drag pizza onto your cutting board, scatter fresh basil leaves on top (torn or whole), and have someone start serving immediately while you get to work on the other pizzas. These pizzas wait for No One!
  9. It is possible to do two or three pizzas at a time on larger grills, all at staggered stages, but this takes practice.


FODMAP Information

Our recipes are based on Monash University and FODMAP Friendly science.

Canned Tomatoes: Monash University has lab tested canned tomatoes and they are low FODMAP at 92 g or 3.2-ounces, which they say is about 3/5 of a cup. Moderate FODMAPs kick in at about 3/4 cup or 115 g, at which point fructose can become an issue.

Cheese: Many cheeses have low FODMAP serving sizes. The low FODMAP diet is not a dairy-free diet. Hard cheeses such as Parmigiano Reggiano or Pecorino Romano have been lab tested by Monash University and are low FODMAP in 40 g amounts.

Garlic-Infused Oil: Make your own Garlic-Infused Oil or buy a commercial equivalent for the easiest way to add garlic flavor to your food. Fructans in garlic are not oil-soluble, so garlic-infused oil is low FODMAP.

Oil: All pure oils are fats and contain no carbohydrates, therefore they contain no FODMAPs.

Sugar: Monash University and FODMAP Friendly have both lab tested white, granulated sugar. Monash states that a Green Light low FODMAP serving size of white sugar is 1/4 cup (50 g). FODMAP Friendly simply states that they have tested 1 tablespoon and that it is low FODMAP. Regular granulated white sugar is sucrose, which is a disaccharide made up of equal parts glucose and fructose. Sucrose is broken down and absorbed efficiently in the small intestine.

Tomatoes: Both Monash University and FODMAP Friendly have lab tested common, beefsteak tomatoes. Monash University lab tests have shown no FODMAPs. FODMAP Friendly gives them a “Pass” at ½ cup (75 g) portions. Cherry tomatoes and Plum (Roma) tomatoes have also been tested by Monash and FODMAP Friendly. Both Monash and FODMAP Friendly recommend 75 g of cherry tomatoes as a serving (about 5 or ½ cup) and 75 g of plum or Roma tomatoes, which is about 1 small tomato or ½ cup.

Yeast: Yeast – fresh, dry and instant – are all low FODMAP.

Please always refer to the Monash University & FODMAP Friendly smartphone apps for the most up-to-date lab tested information. As always, your tolerance is what counts; please eat accordingly. The ultimate goal of the low FODMAP diet is to eat as broadly as possible, without triggering symptoms, for the healthiest microbiome.
