Easy Low FODMAP Pizza Sauce (Keto, Vegan, Refined Sugar-Free)

  • Author: Gail
  • Total Time: 10 minutes
  • Yield: 24 servings 1x


This easy Low FODMAP Pizza Sauce makes pizza night IBS-friendly! It's also Keto, low carb, vegan, gluten-free, and refined sugar-free and can be made Paleo by using a compliant sweetener. 


Units Scale
  • 1 cup strained tomatoes
  • 2 tablespoons tomato paste
  • 2 tablespoons garlic-infused olive oil
  • 1 1/2 teaspoons low FODMAP Italian Seasoning (homemade or store-bought)
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 1/2 teaspoon liquid stevia or your sweetener of choice, to taste (see notes)


  1. Combine ingredients. Whisk all ingredients together in a small saucepan or saucier (mine is 1.5 quarts).
  2. Cook. Place saucepan on medium high heat on the stovetop. Bring to a low boil, whisking occasionally as the sauce heats up. Immediately after the sauce starts to bubble, reduce heat to low (the “Min” setting on my stove) and simmer for 5 minutes or until to your desired thickness, whisking frequently. 
  3. Taste and cool. Remove from heat, taste, and adjust seasonings and sweetener as desired. Allow sauce to cool for a minimum of 10 minutes prior to applying to pizza crust. Use on my Low FODMAP Meatza (Pizza with a Meat Crust - only requires 1/2 of the sauce), as a dipping sauce for my upcoming Low FODMAP Air Fryer Mozzarella Sticks, or on your favorite low FODMAP pizzas, breadsticks, etc.
  4. Store. Store leftover sauce in an airtight container in the refrigerator for 5-7 days or up to 3 months in the freezer. Stir leftover sauce before using.


  • This recipe makes about 1 cup of sauce, enough for 1/2 cup of sauce per pizza.
  • If using as a dipping sauce for breadsticks, mozzarella sticks, etc., this recipe provides eight 2-tablespoon servings.
  • Sweetener: to make this pizza sauce Paleo compliant, I would recommend adding pure maple syrup in increments of 1/2 teaspoon, tasting, and repeating until it is sweet enough to your taste. Depending on your dietary needs, other sweeteners can be used to taste.
