I love a recipe that makes my family ask "I thought you weren't eating carbs?" because they could never guess that what they are eating is actually low carb. This Upside Down Pizza Casserole does just that!
This casserole pairs perfectly with a simple salad or even as a meal all on its own. If you are looking for other keto pizza recipes be sure to check out my keto chicken crust pizza or low-carb garlic bread pizza dip!
Ingredients and substitutions:
- Ground Beef - Ground turkey or Italian sausage would work great in place of ground beef.
- Low-Carb Marinara - Really any marinara sauce will work, but if you are counting carbs I recommend my recipe for easy low-carb marinara or Rao's Marinara sauce.
- Pizza Toppings - For this recipe, I just went with the classic pepperoni, but the sky is the limit here! If you like it on your pizza feel free to use it in this casserole!
- Mozzarella, egg, baking powder, and cream cheese are all critical for making the keto fathead crust and I don't suggest omitting or substituting them.
- Almond Flour - I always get asked about substitutions for almond flour. The crust recipe is essentially a fathead dough with some extra baking powder mixed in. You can substitute the crust recipe with any fathead dough that you like (including coconut flour versions).
- Garlic powder, Onion Powder, and Parsley - use any Italian seasonings that you like, or leave it out if you prefer.
- Butter - you can also use butter-flavored coconut oil, olive oil, or you can omit the topping entirely.
Yes, this recipe makes a great freezer meal! To do this, simply prepare it as directed up until the foil is removed at the end of baking.
Then, remove the casserole from the oven (after 30 minutes of baking) allow it to cool, and then tightly wrap it with foil and/or plastic wrap and transfer to the fridge or freezer.
Ideally, you would want to thaw it halfway before baking it from this point. But if you don't have time just reduce the baking temp a bit and cook covered with foil for 45-60 minutes or until it is heated through.
Most common pizza toppings are perfectly fine to enjoy while you are on a keto diet. Meats (like pepperoni, sausage, Canadian bacon, ham, etc.) and vegetables (like onions, peppers, olives, mushrooms, etc.) can be enjoyed without much concern for going over on carbs.
Regular pizza sauce may contain added sugars and higher carbs. It's best to use a low-carb pizza sauce or make your own with tomato paste and keto-friendly seasonings.
Yes, you can! You can freeze the entire casserole, or slice it and freeze it in individual portions. It is best to allow it to thaw at least slightly before reheating in the oven.

Upside Down Pizza Casserole | Keto, Gluten Free
- 1 lb 80/20 ground beef
- 1 ¼ Cup Low Carb Marinara Sauce
- 1 Cup Mozzarella Cheese shredded
- Pizza Toppings of Your Choice
- Preheat your oven to 375 degrees F.
- Cook the ground beef and drain the excess grease. Combine the cooked beef with the marinara sauce and spread it into the bottom of a greased 7x11 casserole dish.
- Top the meat with about 1 cup of shredded mozzarella cheese, and your favorite pizza toppings.
- For the top "crust" layer, combine the mozzarella cheese with the cream cheese in a medium microwave safe bowl. Heat it in the microwave for 30 second intervals until the 2 cheeses are melted and combine easily. Then, add in the almond meal, baking powder, garlic powder, and egg.
- Spread this mixture on top of the cheese and toppings in your dish. I find it easiest to place the dough in even clumps on the top of the dish and then smoosh them together using my hands until the entire casserole is covered.
- Cover the pan with foil and bake for about 30 minutes. Remove the foil and bake an additional 10 minutes, or until the top is browned.
- For the butter topping: Combine the melted butter with the garlic powder, onion powder, and parsley and brush on top of the "crust."
