Bubble up biscuit pizza casserole brings the comfort of pizza night to one baking dish. Quartered refrigerated biscuits puff beneath savory pizza sauce, melted mozzarella, and the toppings your table enjoys most. The center stays soft and hearty while the edges turn golden, making this an easy dinner for a busy weeknight, a casual game-day table, or a family meal when everyone wants something familiar.
What makes this biscuit pizza casserole work
This recipe keeps the structure of a casserole simple: biscuit dough supplies a fluffy base, sauce adds moisture and tomato flavor, and cheese creates a browned topping that holds the chosen toppings in place. Cutting the dough into small pieces matters because it helps the center cook through before the cheese gets too dark.
It is also flexible without losing its identity. Pepperoni gives the classic pizza profile, while Italian sausage, mushrooms, olives, bell peppers, onions, basil, or spinach can change the flavor. Use sturdy toppings sparingly so the biscuits have room to rise.
Why the layering matters
The sauce belongs on top of the biscuit pieces rather than underneath them because the dough needs direct heat from the pan to rise and set. A relatively even layer also prevents a thick pocket of dough from hiding beneath a heavy topping load. Mozzarella melts into the sauce and protects the surface while the biscuit edges brown, so the casserole has contrasting tender and crisp bites.
For the most reliable result, let the oven finish preheating before the pan goes in. Cold dough and a crowded center can extend the bake, while an accurate 350°F oven gives the cheese time to brown as the biscuits cook. The five-minute rest is useful too: it lets the sauce settle and makes portions easier to lift.
Ingredients for bubble up biscuit pizza casserole
- 2 cans refrigerated buttermilk biscuits, cut into quarters
- 1 15-ounce jar pizza sauce
- 2 cups shredded mozzarella cheese
- Pizza toppings as needed, such as pepperoni, sausage, mushrooms, olives, peppers, onions, or herbs

How to make it
Heat the oven to 350°F and grease a 9-by-13-inch baking dish. Cutting and arranging the biscuit pieces before adding the sauce keeps the layers even and makes it easier to spot any crowded areas in the center.
- Preheat the oven to 350°F and grease a 9-by-13-inch baking dish.
- Cut the refrigerated biscuits into quarters or small bite-size pieces.
- Arrange the biscuit pieces evenly in the prepared dish, keeping them mostly in a single layer.
- Spread the pizza sauce over the dough, then sprinkle on the mozzarella and chosen toppings.
- Bake uncovered for 25 to 30 minutes, checking the center, until the biscuits are cooked through and the cheese is lightly browned.
- Cool for at least 5 minutes before serving.

Serving ideas
Serve warm in squares with a crisp green salad, carrot sticks, or sliced fruit. For a casual dinner, set out extra red pepper flakes and grated Parmesan so each person can finish a portion. A pan makes about eight servings, and it works especially well when dinner needs to go from oven to table without several separate dishes.
Because the topping choices can be divided across the pan, this is a practical recipe for mixed preferences. Keep one side plain with cheese, add pepperoni to another side, or scatter vegetables over the whole dish. Marking the sections before baking also makes serving easier when children and adults want different slices.
Tips and an optional variation
Check the very middle before taking the casserole from the oven; it is the last area to finish. If the dough looks underbaked, cut future pieces smaller or arrange the center in a looser layer. A metal pan may brown differently from glass or ceramic, so use the biscuit texture in the center as the deciding cue.
Optional variation: Add Italian seasoning, Parmesan, and a pinch of red pepper flakes to the sauce. For a vegetable-heavy version, use mushrooms, peppers, onions, and spinach; tuck leafy greens beneath the cheese so they do not dry out.
Storage and reheating
Cool leftovers, cover them, and refrigerate for up to 3 days. Reheat individual portions in an air fryer for a crisp edge, or warm them in the oven until the center is hot. Avoid adding extra sauce before reheating because it can make the biscuit base soggy.
Quick answers for pizza casserole night
Can I make biscuit pizza casserole with one can?
Yes. One can works for a smaller family or a saucier result, but use a smaller baking dish and watch the center closely.
What toppings are best?
Pepperoni, cooked Italian sausage, mushrooms, olives, peppers, onions, basil, and spinach all fit the recipe. Keep wet toppings modest so the biscuits bake properly.
How do I know it is done?
The cheese should be lightly browned and the biscuit pieces in the center should look puffed and cooked rather than wet or doughy.
FAQ: Frequently asked questions

For a neat presentation, let the casserole rest before cutting. The short pause gives the melted cheese a chance to settle around the biscuit pieces, while the sauce thickens enough to stay with each serving. Add a few fresh herbs just before bringing the dish to the table if you want a bright finish.
