Ingredients Needed

- Biscuit Dough: Using store-bought biscuit dough is an easy way to create a tasty and fluffy bottom layer that acts as the crust for this pizza casserole. You could also use homemade instead of canned biscuits.
- Pizza Sauce: Choose your favorite pizza sauce from your local grocery store, or use a homemade sauce if you have a go-to recipe.
- Shredded Mozzarella Cheese: Any kind of shredded cheese works well, but mozzarella is a classic pizza option thanks to how easily it melts.
- Italian Sausage: For some protein and salty, savory flavor. Sweet or spicy sausage both work.
- Pepperoni: Compliments the sausage and channels a classic pizza flavor.
- Black Olives: Feel free to omit if you’re not a fan.
- Green Peppers: Add a bit of color variation and a nice peppery bite.
- Grated Parmesan Cheese: You can never have too much cheese! Freshly grated Parmesan will provide the best results, but store-bought is also fine.
How to Make this Bubble Up Pizza Casserole

- Step 1: Heat a medium skillet over medium-high heat and add the sausage.
- Step 2: Break into pieces with a spoon and cook until fully browned, about 9 to 10 minutes.
- Step 3: Pop open the can of biscuits and cut each biscuit into four small pieces.
- Step 4: Add the biscuit pieces to the bottom of a prepared baking dish sprayed with non-stick cooking spray.

- Step 5: Bake the biscuit layer for 10 minutes at 400 degrees, then remove from the oven.
- Step 6: Spread the pizza sauce over top of the biscuits.
- Step 7: Add 2 cups of cheese, then finish with a layer of sausage, pepperoni, olives, green peppers, and the last 1/2 cup of cheese.
- Step 8: Return to the oven at 400 degrees and bake for 15 to 20 minutes or until hot and bubbly and golden brown on top.

Recipe Tips
- If you’re using Grands biscuits, you’ll need about 12 to fully cover the bottom of your baking dish.
- You can also use this recipe to make mini pizza cups. Instead of a casserole dish, arrange the biscuit pieces in a muffin tin or a cupcake tin and assemble individual pizza muffins. This is great if you have lots of people with different topping preferences.
- Feel free to replace the sausage with ground beef, ground turkey, ground pork, or ground chicken. You can also omit it altogether to make this dish vegetarian.
- For other topping ideas, add mushrooms, onions, bacon, ham, spinach, broccoli, artichoke, or jalapeno peppers.
- Use a blend of different kind of shredded cheeses like colby jack, pepper jack, Monterey jack, or American cheese for some flavor variety.
