Bubble Up Biscuit Pizza Casserole

The kids were arguing over pizza toppings again, so I threw everything into one dish and called it a night. That chaotic Tuesday dinner accidentally became the most requested meal in our house. Something about those buttery biscuit pieces rising through the layers makes everyone forget they ever disagreed in the first place.

My neighbor knocked on the door while this was baking, drawn by the smell of melting cheese and Italian herbs. She ended up staying for dinner with her family, and now four households on our block make this every Friday. Sometimes the simplest meals create the best memories.

Ingredients

• Refrigerated biscuit dough: The base that makes this casserole magic, cutting into small pieces helps them cook through and get those golden crispy edges
• Pizza sauce: Use a good quality sauce or jazz up plain ones with extra garlic and herbs
• Shredded mozzarella cheese: The classic melter that creates those irresistible cheese pulls in every bite
• Shredded cheddar cheese: Adds sharpness and depth that mozzarella alone cannot provide
• Pepperoni: Sliced thin so it crisps up beautifully on top
• Black olives: Optional but they add a salty briny note that cuts through all that cheese
• Diced bell peppers: For color crunch and a fresh element
• Dried Italian herbs: The seasoning blend that brings everything together
• Garlic powder: Essential for that familiar pizza flavor profile

Preheat to 350°F and grease a 9x13-inch baking dish with butter or cooking spray

Let it rest:

Wait 5 minutes before serving so everything sets and makes serving easier

Save

My teenage daughter made this for her friends during exam week when everyone needed serious comfort food. They sat around the baking dish pulling apart cheesy biscuit pieces and talking until midnight. That is when I knew this recipe was about more than just dinner.

Customizing Your Casserole

Swap pepperoni for cooked sausage crumbles or cubed ham for different flavor profiles. Vegetarians can load up on mushrooms bell peppers onions or even artichoke hearts. The biscuit base works with whatever toppings your family loves most.

Make Ahead Magic

Assemble the entire casserole up to 24 hours ahead and keep it covered in the refrigerator. Add 5 to 10 minutes to the baking time since it will be cold going into the oven. This makes it perfect for busy weeknights or feeding a crowd.

Serving Suggestions

A crisp green salad with vinaigrette cuts through the richness perfectly. Garlic bread might seem like overkill but nobody will complain about extra carbs. Keep extra red pepper flakes on the table for heat lovers.

• Let the casserole cool slightly before slicing so portions hold together better
• Leftovers reheat beautifully in the microwave for lunch the next day
• Pair with a simple Caesar salad for a complete satisfying meal

Save

Watch how quickly this disappears from your table, and keep a second can of biscuits in the fridge for next time.

Recipe FAQs

→ Can I make this ahead of time?

Yes, you can assemble the entire casserole up to 24 hours in advance. Cover tightly with foil and refrigerate, then bake when ready, adding an extra 5–10 minutes to the cooking time if baking cold from the refrigerator.

→ What other toppings work well?

Cooked Italian sausage, ground beef, diced ham, or crumbled bacon make excellent meat options. For vegetables, try sautéed mushrooms, onions, spinach, or diced tomatoes. You can also add banana peppers or jalapeños for extra heat.

→ Can I freeze this casserole?

Yes, this freezes well either before or after baking. If freezing unbaked, wrap tightly and freeze for up to 3 months. Thaw overnight in the refrigerator before baking. For best results, freeze after baking and reheat covered at 350°F until warmed through.

→ How do I know when it's done baking?

The casserole is ready when the biscuits are golden brown and puffed, the cheese is fully melted and bubbly, and there are no raw doughy areas visible in the center. A knife inserted into the biscuits should come out clean, not doughy.

→ Can I use homemade biscuit dough instead?

Absolutely. Homemade biscuit dough works beautifully—prepare your favorite buttermilk biscuit recipe, cut into pieces, and proceed as directed. You may need to adjust the baking time slightly depending on your dough's thickness.

→ What size pan should I use?

A standard 9x13-inch baking dish works perfectly. If using a larger pan, the biscuits may brown faster, so check for doneness at 25 minutes. A deeper dish will take longer to cook through—extend baking time as needed until biscuits are fully cooked in the center.
