How to Make Bubble Up Pizza Casserole
-
Preheat your oven to 375°F (190°C). Grab a 9×13-inch baking dish and give it a generous spray of cooking oil to prevent sticking.
-
Cook the ground beef in a skillet over medium heat. Break it apart as it browns for about 3-4 minutes, adding a pinch of salt and pepper to enhance the flavor.
-
Sauté the diced bell peppers in the skillet alongside the beef until they’re soft and vibrant, typically 2-3 minutes. Drain any excess liquid and stir in the pizza sauce until well blended.
-
Cut the biscuits into six equal pieces each, creating bite-sized chunks. Layer them evenly in the prepared casserole dish—this will be the wonderful base of your casserole!
-
Layer the beef mixture over the biscuit pieces, making sure to spread it out evenly. Then, sprinkle the shredded mozzarella cheese and arrange the turkey pepperoni slices on top like a pizza!
-
Bake the casserole uncovered for 25-30 minutes. It’s done when the biscuits rise and turn golden brown. Let it cool for 5-10 minutes for the flavors to settle before diving in.

Expert Tips for Bubble Up Pizza Casserole
-
Cook Thoroughly: Ensure the beef is fully browned with no pink spots. Undercooked meat can compromise the safety and flavor of your casserole.
-
Crispy Top: If the cheese is browning too quickly, cover the dish with foil halfway through cooking to ensure even baking without burning.
-
Oven Thermometer: Always check your oven temperature with a thermometer; inconsistent temperatures can affect how your casserole bakes, leading to soggy or uneven results.
-
Flavor Boost: Don’t hesitate to add Italian herbs like oregano or basil into your beef mixture for an extra kick of flavor in your Bubble Up Pizza Casserole.
-
Reheating Best Practices: Use an air fryer for leftovers; this method will keep the casserole crisp on the outside while remaining soft and delicious on the inside.
