This keto-friendly pizza casserole takes on the appearance of deep-dish pizza or lasagna, hence its nickname, “pizza bake.” It’s a simple recipe that takes about 20–25 minutes to bake.

Like other Italian recipes, this one employs Italian seasoning, mozzarella cheese, and marinara sauce.

To keep it a low-carb recipe, we’ll be using cauliflower rice to cook it as a base in lieu of regular crust.

Bravenly premium supplements

​If pizza is one of your favorite foods, this is a perfect solution to maintain a low-carb diet and still munch on that cheesy goodness on those busy weeknights.

It’s a recipe you will want to add to your keto meal plan for sure.

Making this pizza keto casserole is pretty straightforward.

You’ll start by preheating the oven to 400 degrees and greasing the casserole dish with a couple of tablespoons of olive oil.

Then, proceed to cook the cauliflower rice according to the instructions on the package and set it aside.

Next, combine the cooked cauliflower rice in a medium-sized bowl with salt, black pepper, and red pepper flakes with the marinara sauce.

Spread the cauliflower mixture to the bottom of the 13×9-inch casserole dish and top it with half the shredded mozzarella cheese. Next, add the slices of bell peppers, mushrooms, and pepperonis and press them lightly into the casserole.

Then add the remaining mozzarella cheese and sprinkle the parmesan cheese over the top of the casserole with a dash of red pepper flakes.

Join Our Jesus And Keto Movement 

Randy and I came to the keto diet looking at it from a Christian perspective. As believers, we live our lives supported by God’s grace.

So when the Holy Spirit led us to combine our Christian faith and the keto diet, we did so in hopes of finding lasting transformation.

To say we needed God’s intervention is to put it mildly. When we followed the Holy Spirit’s prompting, we got on the path to real transformation.

Knowing firsthand the benefits of this decision, we have created a closed Christian group that is using the keto diet to transform their lives. 

We invite you to join our Private Facebook Group and see if it’s not the key you have been missing.

Be sure to request our FREE Jesus and Keto E-Book (First 7 Days). We hope it blesses you.
