If there’s one dish that perfectly captures the magic of comfort food meeting weeknight convenience, it’s bubble up biscuit pizza casserole. This cozy, crowd-pleasing bake takes everything you love about pizza—melty cheese, savory sauce, bold toppings—and combines it with soft, fluffy biscuit dough that “bubbles up” as it bakes into golden perfection. The result is a warm, hearty casserole that feels nostalgic, indulgent, and unbelievably easy to make.

Bubble up casseroles became popular for a reason: they’re approachable, flexible, and practically foolproof. Instead of dealing with pizza dough, rolling crusts, or shaping anything at all, you simply cut refrigerated biscuit dough into bite-sized pieces and let the oven do the work. As the casserole bakes, the biscuits puff up through layers of sauce and cheese, soaking in flavor while staying tender inside and lightly crisp on top.

This bubble up biscuit pizza casserole is ideal for busy families, potlucks, game nights, and casual gatherings. It feeds a crowd, reheats beautifully, and invites customization. Whether you stick to classic pepperoni or load it up with vegetables and sausage, this dish adapts to whatever you have on hand. It’s pizza night—reimagined in casserole form.

What makes this recipe especially lovable is how comforting it feels. The smell alone—bubbling cheese, baked biscuits, Italian seasoning—instantly signals that something good is coming out of the oven. It’s the kind of meal that brings people to the kitchen before you even call them to the table.

Ingredients:

Refrigerated biscuit dough
Pizza sauce
Shredded mozzarella cheese
Pepperoni slices
Cooked Italian sausage, crumbled
Green bell pepper, diced
Black olives, sliced
Olive oil
Italian seasoning
Garlic powder
Red pepper flakes (optional)
Fresh basil or parsley (for garnish)

Instructions:

Preheat your oven to 375°F (190°C) and lightly grease a baking dish with olive oil.
Cut the refrigerated biscuit dough into quarters and place the pieces in a large mixing bowl.
Add pizza sauce to the biscuit pieces and toss gently until all pieces are evenly coated.
Stir in half of the shredded mozzarella cheese, ensuring it’s well distributed.
Add pepperoni, cooked sausage, bell pepper, and black olives to the bowl.
Sprinkle in Italian seasoning, garlic powder, and red pepper flakes if using.
Mix gently to combine, being careful not to mash the biscuit dough.
Transfer the mixture into the prepared baking dish and spread it evenly.
Sprinkle the remaining mozzarella cheese evenly over the top.
Bake uncovered for 35–40 minutes, until the biscuits are fully cooked and the cheese is melted and golden.
If the top browns too quickly, loosely cover with foil during the last 10 minutes.
Remove from the oven and let rest for 5 minutes before serving.
Garnish with fresh basil or parsley and serve warm.
