This is the 30-minute pizza casserole that kids and busy parents love. Refrigerated biscuit dough cut into pieces, tossed with marinara and pepperoni, topped with mozzarella, baked until the biscuits puff up golden and the cheese bubbles. All the pizza flavor, half the effort, zero dough-making. Serves six, dump-and-bake easy.
Fun fact: "bubble up" bakes became a Midwestern American potluck phenomenon in the 2000s when Pillsbury refrigerated biscuit dough met the casserole tradition. The genius is that the biscuit pieces "bubble up" between the sauce as they bake, creating doughy pockets that soak up the marinara. It spawned dozens of variations — enchilada, sloppy joe, chicken alfredo bubble ups.
Why this recipe works
- CUT biscuits into quarters. Smaller pieces = more surface area to crisp and more nooks to catch sauce. Whole biscuits stay doughy inside.
- TOSS, don't layer. Tossing the biscuit pieces IN the sauce coats every side so they bake evenly, not just on top.
- CHEESE LAST. Add cheese in the last 10 minutes so it melts golden without burning while the biscuits cook through.

Pro tips for the best bubble up pizza bake
- USE GRANDS biscuits for bigger pieces. The flaky layers puff up dramatically. Regular biscuits work but stay denser.
- MAKE IT YOUR OWN. Sausage, mushrooms, Canadian bacon, jalapeños — any pizza topping works tossed in.
- DON'T SKIP the rest. 5 minutes lets the casserole set so it scoops cleanly instead of falling apart.
- DIPPING sauce is key. Warm marinara or ranch on the side makes it feel like real pizza.
Frequently asked questions
Can I make this ahead?
Best fresh (biscuits get soggy). But you can prep toppings + sauce ahead and assemble at bake time.
Can I use homemade biscuit dough?
Yes — drop-biscuit dough works. Refrigerated canned dough is the convenience shortcut.
How do I store leftovers?
2 days fridge. Reheat in the oven (microwave makes biscuits gummy).
Can I freeze it?
Not great — biscuit texture suffers. Best eaten fresh or within 2 days.
Vegetarian version?
Skip pepperoni, add mushrooms, peppers, onions, olives. Same technique.
