Is Pizza Okay on the Keto Diet?

To be successful on the keto diet, you must avoid eating traditional pizza with flour crusts and other high carbohydrate crusts. A popular style of no crust pizza on the keto diet is the keto pizza casserole. However, some low carb pizza crusts are acceptable, including:

  • Fathead Dough Crust (using either almond flour or coconut flour)
  • Cauliflower Crust (sometimes, see below)

Are All Cauliflower Pizzas Keto-Friendly?

Unfortunately, no. The cauliflower crust in this recipe most certainly is, but I’ve seen plenty of cauliflower crust pizzas popping up in restaurants and the freezer section of the grocery store that are not keto-friendly. They’re low carb, but too high in carbs for a keto diet. Always check nutrition facts before consuming a cauliflower crust pizza!

Where Do I Find Keto Pizza Sauce?

When sourcing keto pizza sauce, you want to look for a sauce that contains no added sugar. With high-carb sugar eliminated, you’ll find that many pizza sauces are surprisingly low in carbs! My favorite brand is Rao’s, which contains only 3g net carbs per 1/4 cup. I’ve found Rao’s at Walmart, Meijer, and Kroger.

Is it Easy to Make a Keto Pizza Crust?

Yes, most keto pizza crusts have about 5 ingredients or less and require a minimal amount of time to prepare and bake. Here are a few additional keto pizza recipes you will love!

What Can I Serve with My Casserole?

Since this casserole is a little low in fat, I highly recommend serving it with a small side salad topped with keto ranch dressing! Also, nothing beats a few more Italian options when you are eating Italian! Try some delicious Keto Garlic BreadKeto Antipasto Salad and Keto Mac and Cheese on the side.

Love Pepperoni?

Then I highly suggest making these easy keto pepperoni chips for a fun no-carb snack.

    I was surprised how good this Keto Pizza Casserole is. I had concerns that the cauliflower rice in the crust would take away from the flavor but I was so wrong. My kids loved this pizza casserole as well as me. I will certainly be making this many times in the future. It is so simple to prepare which is also a big plus.
