Make it on a summer day, pizza night, or winter when you need to light up the house. If you follow a keto diet, you will love this pizza as it is the best recipe to make almost real pizza looking and tasting. Better than chicken pizza or pizza using coconut flour. Trust me. 

Fathead Dough Recipes

Fathead dough is so versatile that you can replace it with almost anything that asks for dough. You can even make desserts with it and various other dishes.

Best Keto Pizza Crust Recipe

Once you try the crust, you will not stay with this recipe only. Made only with almond flour, egg, and cheese, you need nothing more in this keto pizza crust recipe. Not even coconut flour or cream cheese, as some of the recipes suggest. 

Our bacon pizza is another excellent example.

Low Carb Pizza Crust Made With Colorful Tomatoes as Topping?

I have decided to make this lovely rainbow colors pizza after seeing in the market various colors of tomatoes being sold. I had to buy them but was unsure how to use them to my best liking.

As I finally decided to make this favorite pizza, I still had a few lovely colors left. 

Well, I just bought much, much more than I needed. As a second recipe, I have decided to make picturesque tomato mozzarella baked chicken, which is also perfect to try.

What Do You Need To Make Best Keto Pizza Recipe?

Let us dive into making this great recipe. I have not added complete steps on making fathead dough, as the whole post is made for you separately. I have also prepared a video with full instructions for those who prefer more visual steps. 

Kitchen gadgets needed:

  • Cooking pot for fathead base
  • Rolling pin for fathead base
  • Pizza stone – you can also use a baking sheet or pizza pan
  • Cheese shredded
  • Fork

Ingredients needed:

  • Fathead dough
  • Various colors of tomatoes
  • Mozzarella cheese
  • Chives

*Exact measurements are listed in the recipe card below.


First Step: Prepare Ingredients

Prepare all ingredients needed to make this pizza. 

Rainbow Pizza Ingredients needed.

Second Step: Prepare the Fathead dough

In the keto fathead pizza dough recipe, I have mentioned all the steps from a complete start to making the dough. You can have a look in case you are not sure how to make this lovely fathead crust the easiest way. To make your keto crust, you only need one cup almond flour, an egg, 2 cups of shredded cheese, and garlic powder if you wish.

Third Step: Bake the Fathead Crust

Once you choose your baking dish for this pizza, be it greased pizza pan, baking sheet, or pizza stone, roll out the dough into a round shape. 

Using a fork, make small holes around the spread dough and bake it for 8 minutes at 200 degrees Celsius or 390 degrees Fahrenheit.

Fourth Step: Prepare Tomatoes

Depending on how many colors of tomatoes you have, cut them into half slices and place each color into a separate bowl. In that way, spreading them once your crust is ready will be much easier.

Fifth Step: Mozzarella

As mentioned a few times, I never buy shredded cheese. They are usually covered with starch for cheese not to stick, and that is a big NO-NO for us.

I always buy all the cheeses in bulk and shred them myself.

Sixth Step: Assemble the pizza

Add shredded mozzarella cheese in the middle of the pizza crust.

Starting from the lightest colors of tomatoes, spread them evenly onto the pizza crust to form a rainbow like looking dish.

Seventh Step: Outer layer

Finish the pizza with the darkest colors or tomatoes around the outer layer.

Eighth Step: Bake

Place assembled pizza back into the oven for another 8 minutes or until the cheese melts and the tomatoes soften.

Ninth Step: Chives

Once the pizza is made and ready to serve, spread chives around the outer layer to give it a beautiful green color.

Do not bake the pizza with chives. Otherwise, they will become brown and not good-looking.

Recipes That Pair Well With This Easy Keto Pizza:

Can I Use Other Pizza Topping or Pizza Sauce?

This recipe has no base sauce, but you can add our favorite pizza toppings, such as marinara sauce or low carb pizza sauce, if you wish.

What Other Vegetables Can I Use To Make Rainbow Pizza?

The idea here is to have the colors match into a rainbow.

I have picked tomatoes only because of seeing them all in the market. But if you do not have tomatoes, you can also add different veggies and decorate the pizza however you like.

For example, green, broccoli, or green peppers works perfectly. Asparagus will work lovely as well. You can also add dried tomatoes to build different shades.

As yellow, you can use yellow peppers.

Darker colors can be achieved by using dark onions or olives, which are also perfect for pizza.

Do I Have to Pre-Bake the Fathead Pizza Crust?

In this particular recipe, I suggest you bake the crust first.

Otherwise it will turn all of the tomatoes or chosen vegetables mushy and darker in color. You want to avoid baking the veggies thoroughly for the rainbow colors to stay vibrant. And if you do not bake the crust first, you will have to keep the pizza in the oven for much longer.

Can I Store Keto Pizza Dough?

If you have tried this recipe, you will realize the dough is extra delicious and great for many recipes. You can double the amount and store leftover keto dough for other lovely recipes. 

How Long Can I Store Whole Pizza?

If not eaten immediately, you can store the pizza in the fridge for 2-3 days.

I suggest reheating the pieces in the oven once ready to serve. Using the oven will give back the pizza a lovely texture and taste.

Can I Freeze Keto Friendly Fathead Pizza Dough?

I suggest freezing only the Fathead dough. I do this all the time. Just bake the fathead crust and cut it into desired slices.
Those are then packed into parchment paper and placed into the freezer.
When you are ready to make your pizza, take the frozen keto pizza pieces you need from the freezer and let them thaw.
Add whatever topping you desire and bake again in the oven.

  1. Dear Erin,
    I live in Austria and there is a brand I always use. The name is Galbani, but it is a big block of mozzarella. I always shred it myself, because already pre-shredded contains starch. This works perfectly for all of the recipes.

  2. Thank you for your recipes. I am new to Keto and am loving your website. Can the fathead dough for the pizza be prepared and baked the night before and kept in the refrigerator to top with pizza toppings the next day?
