Rainbows are happening in the kitchen today! We’ve transformed the best cauliflower crust pizza into a rainbow cauliflower crust pizza. The rainbow veggies are so delicious and even more pleasing to the eye. My daughters fell in love with this pizza and could not eat enough of it!
But why make cauliflower crust rainbow pizza?
- It’s beautiful and colorful
- It’s packed with veggies and veggies are good for you
- Because cauliflower crust pizza is tasty!
Top this delicious pizza with any type of veggies you have. Use whatever is in season or your favorite pizza toppings. Just be sure to dice the veggies really small and arrange the veggies from light to dark to create a rainbow look. 
Begin by make the crust. Cauliflower pizza crust is much faster to make than regular pizza crust because no rising needed.
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.
What 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. 
Remove from oven and add the pizza sauce, cheese, and diced veggies. Be sure to arrange the veggies in a rainbow pattern! 
Bake for another 15 minutes or until the cheese is fully melted and the edges are browned.
Slice the pizza, serve hot. The pizza will last in the fridge for up to 3 days. Re-heat in microwave or toaster oven. Enjoy!
Rainbow Cauliflower Crust Pizza
Ingredients
- 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)
- 1/2 cup marinara sauce
- 1 cup mozzarella cheese
- 1 cup diced bell peppers, yellow, orange, red, green, or any combo of your choice
- 1/2 cup broccoli florets
- 1/2 cup diced red onion
- 1/4 cup canned corn, optional and not included in nutritional facts
- 1/2 cup tomatoes, diced
Instructions
- Preheat oven to 500 degrees F.
- 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.
- 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.
- 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.
- 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.
- Place the pizza back in the oven and bake for another 12-15 minutes.

Hi….I’m concerned about this being listed as a keto pizza with corn on it…corn has more carbs than potatoes do! I see you’ve left it out of the nutritional info, but please add in that the corn CAN’T be consumed on a keto diet as it will take someone out of ketosis. This is actually very important because it’s easy to see a “keto recipe” and make it like the photo because one doesn’t realise.
This is absolutely delicious, it has become our new favorite pizza, my children love it and so do I perfect for my diet as well!😊
Only thing I find I need to do is perfect my cauliflower crust making skills lol
Thank you so much for this recipe!

It was delicious!!! Thanks for the recipe. A new favourite.
Hi
I LOVE your receipt. I foUnd it in german, but i think they just copy everything even the pics. The traNslation was horrible.
I will defently cook this nice pizza for my family!!! Thnx for charing.
How do I make this pizza be vegan?
So i followed this recipe to a T and not only does the dough not look right there’s no way it is 4 servings. I wish I had none this recipe wasn’t going to work right for me before I put in so much effort to make it. I won’t be doing this one again.
This rainbow cauliflower crust pizza looks absolutely fantastic. Beautiful photos, too. I look forward to trying this.
This is absolutely magnificent, scrumptious, delicious, super yummy rainbow cauliflower crust pizza. Never seen something like this! Definitely i will try to make it too! Thx for sharing!
Thanks so much, Jill! 🙂
Can you freeze for future use?
Thanks Laura
Wow, I just love this amazing recipe!!!! So healthy and colorful at the same time. Have to try making it very soon.
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.
Wow! This looks fantastic. The fate of the cauliflower head in my fridge is now determined. So great to find this site. Thank you so much
Wow, it is good to eat different vegetables of different colors. This makes that super easy!
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!
Wow! Just. Wow! I cannot wait to try this. Such a brilliant take on “eating the rainbow”! I’m going to share this with everyone I can!
Layla I saw this on Pinterest and since then I have been wanting to try!! This is stunning and I am sure your daughters loved every bit of it! 🙂
Thanks so much for stopping by Ami! I’m sure you will love it!
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
The recipe serves four and the nutritional facts are per serving/slice of pizza. I just happened to cut mine into 5 slices.
I love that this is totally VEGGIE-packed! Also that it’s beautiful!
Oh my god! So much goodness on a pizza. Will try this xx
Looks delicious! Can’t wait to try it! ♡
What do you suggest for pizza sauce ?
Hello,
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.
I don’t have a microwave. Can I steam or boil the cauliflower?
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.
Hi,
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.
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!
It looks absolutely delicious! Thank you for including the nutritional values, most recipes and bloggers do not!!
Thanks so much!
