Bubble Up Pizza Casserole with Biscuits (Kid-Friendly!)

Bubble Up Pizza Casserole with Biscuits blends classic pizza ingredients like ground beef, pizza sauce, shredded mozzarella, and sliced pepperoni over cut biscuit dough pieces. The biscuit pieces soften and rise during baking, bubbling up and creating a tender base that absorbs the robust pizza sauce and meat flavors. Adding diced bell peppers contributes a subtle sweetness and texture contrast, though they can be omitted if preferred. After topping with pepperoni and cheese, the casserole is baked until the biscuits are cooked and the cheese melts golden brown.

The resulting texture combines soft, doughy biscuit pockets with savory meat and melted cheese, imitating pizza flavors in a casserole form. This format allows for easy portioning and is convenient for family meals. Variations can include more vegetables or increased protein content, making it adaptable to preferences.

This casserole serves well warm as a standalone meal or with a simple side salad. It is also suitable for preparing in advance and reheating; leftovers reheat well in an air fryer, which restores a crispy edge while keeping the interior soft. The dish can be frozen once cooled and sliced for convenient future meals.

Adjust biscuit brands or use gluten-free dough if needed. Watch the baking time to prevent excessive browning of the biscuit tops by covering with foil as necessary. Let the casserole rest briefly after baking to firm up the layers for easier slicing.
