Keto Cauliflower Pizza Casserole

Keto Recipes > Dinner

This keto cauliflower pizza casserole combines the flavors of pepperoni pizza with the creamy comfort of a casserole. This recipe brings casseroles to a whole new level!

Instead of using carb-loaded pasta as a base, we use steamed cauliflower. Not a cauliflower fan? Try the recipe anyway. It doesn’t taste one bit like cauliflower. Instead, it’s more like macaroni and cheese meets pepperoni pizza. The sauce is rich and creamy with notes of tomato, garlic, basil and oregano. The red pepper flakes add just a little bit of heat and complexity. Add in layers of pepperoni and gooey mozzarella cheese, and this recipe becomes comfort food nirvana.

Just because it’s delicious doesn’t mean this recipe is difficult. This casserole is easy to put together and makes an ideal weekday dinner. Don’t worry if you have extra because it tastes even better the second day. Just cover and refrigerate the unused portion. To reheat, take out the desired amount and reheat with the method of your choice.

When making this casserole, the cauliflower is steamed lightly before the dish is assembled. Don’t over-cook it because it will cook a bit more in the oven. You can save time by beginning the sauce while the cauliflower steams. After the sauce and the cauliflower are finished, assembling the casserole is a snap. Once it’s put together, pop it in the oven and relax while the oven bakes it into gooey goodness.
