This keto pizza casserole has all the best parts of a pizza all baked together, creating the ultimate low carb comfort food! Cheesy, meaty, and made with 5 ingredients, it takes just 20 minutes to make!
Preheat the oven to 180C/350F. Grease a 9 x 13-inch baking dish and set aside.
Prepare the pasta as per the directions. Once al dente, remove from the heat and drain. Set aside.
In a deep pot or large saucepan, add the olive oil and place over medium heat. Once hot, add the onion and garlic and cook for 1-2 minutes, until fragrant. Add the ground sausage, break apart in the pan, and cook until browned. Add the pizza sauce and mix well. Let the mixture simmer for 4-5 minutes. Remove from the heat.
Add the cooked pasta into the sausage sauce mixture and mix until combined. Fold through half the parmesan cheese. Transfer the mixture into the greased baking dish. Sprinkle with remaining parmesan cheese, mozzarella cheese, then top with pepperoni. Place the dish in the oven and bake for 20 minutes, or until the cheese has melted and the edges are golden.
Remove the casserole from the oven, before slicing and serving.
