Prefer a different type of cheese? No problem! The possibilities are endless, and I’ll share some of my favorite variations a bit later on.
But perhaps my favorite thing about this Pepperoni Pizza Casserole is how comforting and satisfying it is.

It’s the kind of meal that instantly puts a smile on your face and fills your belly with pure happiness. Trust me, one bite and you’ll be hooked!
Ingredients for Pepperoni Pizza Casserole
- Refrigerated biscuit dough: I like to use the flaky, buttery kind for this recipe, but you can use any type you prefer.
- Pepperoni: You can’t have a pepperoni pizza casserole without the pepperoni! I like to use the classic round slices, but you can also use the mini pepperoni or even swap in Italian sausage if you prefer.
- Mozzarella cheese: Gooey, melty mozzarella is the perfect cheese for this dish. I like to use a combination of shredded and sliced mozzarella for the best texture.
- Marinara sauce: Any good-quality marinara or pizza sauce will work here. I like to use a sauce that’s heavy on the herbs and garlic for maximum flavor.
- Parmesan cheese: A sprinkle of freshly grated Parmesan adds a nice salty, nutty flavor to the casserole.
- Dried Italian seasoning: This blend of herbs like oregano, basil, and thyme really takes the flavors to the next level.
Hailee’s Tip:
For the best texture, make sure to let the biscuits cool slightly before cutting them into pieces. This will help them hold their shape better in the casserole.
Optional Add-Ins and Variations
As I mentioned, this Pepperoni Pizza Casserole is super versatile, so feel free to get creative with your add-ins and variations. Here are a few of my favorite ideas:
- Veggies: Sautéed mushrooms, bell peppers, onions, or even spinach would all be delicious additions.
- Meats: In addition to or instead of pepperoni, you could use Italian sausage, ground beef, or even chopped bacon.
- Cheese: Try swapping in different types of cheese, like cheddar, provolone, or even a sprinkling of feta.
- Seasonings: Add a pinch of crushed red pepper flakes for a little extra heat, or try using a blend of Italian herbs instead of the dried seasoning.
How to Make Pepperoni Pizza Casserole
Alright, let’s get to the good stuff – the step-by-step instructions for making this incredible Pepperoni Pizza Casserole!
-
- Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish.
- Open the can of biscuit dough and separate the biscuits. Cut each biscuit into quarters and arrange them in a single layer in the prepared baking dish.
Hailee’s Tip:
Make sure to let the biscuits cool for a few minutes before cutting them. This will help them hold their shape better in the casserole.
-
- Arrange the pepperoni slices in a single layer on top of the biscuit pieces.
- In a medium bowl, mix together the mozzarella cheese, Parmesan cheese, and Italian seasoning. Sprinkle this cheese mixture evenly over the pepperoni layer.
- Pour the marinara sauce over the top, making sure to cover the entire surface.
What I Messed Up At First:
When I first made this recipe, I forgot to spread the sauce all the way to the edges of the dish. This led to some dry, uncooked biscuit pieces around the perimeter. Learn from my mistake and make sure to fully cover the surface with the sauce!
- Bake the casserole for 25-30 minutes, or until the biscuits are golden brown and the cheese is melted and bubbly.
- Remove the casserole from the oven and let it cool for a few minutes before serving.
Common Mistakes to Avoid
While this Pepperoni Pizza Casserole is pretty foolproof, there are a few common mistakes to watch out for:
- Overcooked biscuits: Keep a close eye on the biscuits during the baking process to ensure they don’t dry out or become too crispy.
- Uneven sauce distribution: As I mentioned earlier, make sure to spread the sauce all the way to the edges of the dish to prevent any dry, uncooked biscuit pieces.
- Too much cheese: While I’m all for the cheesier the better, too much mozzarella can make the casserole a bit heavy and greasy. Stick to the recommended amounts for the best texture.
My Tested Substitutions
I’ve made this Pepperoni Pizza Casserole countless times, and I’ve found that it’s pretty forgiving when it comes to substitutions. Here are a few options that I’ve tried and loved:
- Biscuit dough: In a pinch, you can use refrigerated crescent roll dough or even a pre-made pizza crust in place of the biscuits.
- Pepperoni: As I mentioned, you can swap in Italian sausage or even chopped bacon for the pepperoni. Just adjust the cooking time as needed.
- Cheese: While mozzarella is the classic choice, you can use a blend of different cheeses, like cheddar, provolone, or even a sprinkling of feta.
- Sauce: Any good-quality marinara or pizza sauce will work here, so feel free to use your favorite brand or even a homemade sauce.
How to Customize This Pepperoni Pizza Casserole
One of the things I love most about this recipe is how easy it is to customize. Here are a few ideas to help you make it your own:
- Vegetarian: Swap out the pepperoni for sautéed mushrooms, bell peppers, and onions for a delicious meatless version.
- Gluten-free: Use gluten-free biscuit dough or a pre-made gluten-free pizza crust to make this dish gluten-free.
- Spicy: Add a sprinkle of crushed red pepper flakes or a few dashes of hot sauce to give it a little kick.
- Breakfast: Serve it up for breakfast by adding scrambled eggs or crumbled sausage to the mix.
