Here are a few tips for making the best low carb cauliflower crust:

  • Allow the minced and steamed cauliflower to cool before extracting the water.
  • Using a soft kitchen towel to extract the water will give you the best results.
  • Make sure to get all the water out of it, like every last bit! I squeezed my water how so hard I ended up with an amazing ball of cauliflower. remember, the trick to making a perfect cauliflower crust is to squeeze out as much liquid as possible out of the cauliflower.

Be sure to check out the full post here for more a more detailed explanation and step-by-step photos.Rainbow Cauliflower Crust PizzaWhat you are seeing above is the cauliflower ball after I have processed it in the food processor, then steam it in the microwave, and drained all the water out of it. After you have done so, place the cauliflower ball in a bowl and add an egg, 1/4 cup Parmesan cheese, 1/4 mozzarella cheese (you can also omit the parmesan and use 1/2 cup mozzarella instead), salt, garlic powder (optional) rosemary and oregano.  Mix it all in with a wooden spatula or your hands until a dough forms.

Next, spread the dough out on a lightly greased parchment paper or a pizza pan like you would with regular pizza dough and bake for 12-15 minutes or until the crust begins to brown on the edges. This is probably a good to dice up the veggies. Rainbow Cauliflower Crust PizzaRemove from oven and add the pizza sauce, cheese, and diced veggies. Be sure to arrange the veggies in a rainbow pattern! Rainbow Cauliflower Crust PizzaBake for another 15 minutes or until the cheese is fully melted and the edges are browned.

Rainbow Cauliflower Crust Pizza

4.5 from 4 reviews
Prep time:
Cook time:
Total time:
Serves: 4


  • 1 small to medium sized head of cauliflower - should yield 2 to 3 cups once processed
  • ¼ cup shredded Parmesan cheese
  • ¼ cup mozzarella cheese
  • 1 egg
  • ¼ teaspoon salt
  • ½ teaspoon garlic powder
  • ½ teaspoon basil or rosemary, minced (or dry)
  • ½ teaspoon oregano, minced (or dry)
  • ½ cup marinara sauce
  • 1 cup mozzarella cheese
  • 1 cup diced bell peppers (yellow, orange, red, green, or any combo of your choice)
  • ½ cup broccoli florets
  • ½ cup diced red onion
  • ¼ cup canned corn (optional and not included in nutritional facts)
  • ½ cup tomatoes, diced


  1. Preheat oven to 500 degrees F.

  2. Remove the stems from the cauliflower and cut into chunks, Place the cauliflower into a food processor and pulse it until it resembles the texture of rice. If you don't have a food processor, you can use a cheese grater or chop it very finely.

  3. Microwave the processed cauliflower uncovered in a microwave safe bowl for approximately 4-5 minutes on high. Remove it from the microwave and allow it to cool for at least 4-5 minutes (trust me don't rush this step!). After the cauliflower is slightly cooled, place it in a kitchen towel and squeeze all the liquid out of it. Be sure to squeeze as much liquid as humanly possible.

  4. Combine the cooked cauliflower, egg, garlic, cheese, and seasonings. Stir until a dough texture forms. Spread the cauliflower mixture out onto lightly greased parchment paper or a pizza pan in the shape of a pizza crust.

  5. Bake the crust for approximately 10-15 minutes (depending on your oven), or until the crust is golden and crispy. I cooked mine for approximately 15 minutes. After the crust is golden remove it from the oven and top with pizza sauce then cheese then the chopped veggies.

  6. Place the pizza back in the oven and bake for another 12-15 minutes.

    Made this for a pair of toddler boys today! The crust was fantastic and the boy ate some veggies! Thanks for sharing the great recipe.

  • Karen

    This looks wonderful – my rainbow-loving daughter will adore it!

    I see that you’ve set the oven for 500 degrees. I usually bake crusts (including my other recipes for cauliflower crust) at 400, then broil the toppings. Can I do that here? (500 degrees for over 30 minutes seems a bit energy inefficient, even consider a potentially longer baking time at a lower temp. Plus…summer in Georgia makes running the oven uncomfortable anyway!) Thanks!

    hi cannot wait to try this recipe!!
    but i am confused about the serving sizes. the pizza is cut into 5 slices but the nutritional values say there are four servings? Does that mean there are 200 calories per slice or 200 calories per pizza or ?? could u please clarify how much pizza the recipe makes and the calories for each slice
    thanks so much xxx

    I absolutely love the idea, however I just learned that my 6 year old has high cholesterol so we should avoid egg and cheese. You already explained how to substitute egg, any idea if I can omit cheese or substitute with something else? As much as I would like to keep him on diet, I still want to make sure that his meals are tasty. I would appreciate any suggestions.

    • Layla

      Yes, you can steam or boil it for 5 minutes before placing it in the food processor. If you are boiling it I suggest simply thinly dicing the cauliflower with a knife after boiling it instead of using the food processor because it can become too mushy.

  • Stephanie

    What can I substitute the egg for in this rainbow pizza recipe?
    My friend has a severe egg allergy but we would really like to try this.

    • Layla

      Hi Stephanie,

      You can use a flaxseed “egg” by combining 1 tablespoon of ground flax seed with 3 tablespoons of water. Stir well, and place in the fridge to set for 15 minutes. After 15 minutes, the result should be a sticky egg-like substitute.

      Hope that helps!
