Preparation Phase & Tools to Use

To make this recipe seamless, you’ll need a few essential kitchen tools:

• 9×13-inch Baking Dish: A casserole-style baking dish ensures even cooking and enough space for the biscuits to expand.
• Mixing Bowl: Useful for combining the biscuit dough with sauce and toppings evenly before layering into the dish.
• Kitchen Shears or Knife: To cut the biscuit dough into bite-sized pieces.
• Spatula or Spoon: Helps mix ingredients gently and transfer everything into the dish without mashing the dough.
• Oven Mitts: Safety first! Always have these ready for hot casserole removal.

Each tool plays a small but critical role in creating that perfect bubbly, golden casserole with every layer well-coated and evenly baked.

Preparation Tips

Cut the biscuit dough into uniform pieces to ensure they cook evenly and rise properly. Don’t overload the dish with too many toppings — it can weigh down the dough and affect the bubbling process. When mixing the biscuits with the sauce and cheese, do it gently to keep the dough intact and airy. If using additional toppings like veggies or sausage, pre-cook them to avoid excess moisture in the dish. Always keep an eye on the casserole in the last few minutes of baking — you want golden brown edges and melted, bubbly cheese across the top.

Ingredients for this Bubble Up Biscuit Pizza Casserole

• 1 can (16 oz) refrigerated biscuit dough (cut into quarters)
• 1 1/2 cups pizza sauce (store-bought or homemade)
• 2 cups shredded mozzarella cheese
• 1/2 cup grated Parmesan cheese
• 1 1/2 cups sliced pepperoni (mini or regular, halved if large)
• 1 tsp Italian seasoning
• 1/2 tsp garlic powder
• Optional: 1/2 cup cooked sausage crumbles
• Optional: 1/4 cup diced green bell peppers
• Optional: 1/4 cup sliced black olives
• Fresh chopped parsley for garnish (optional)

Step 1: Preheat the Oven

Start by preheating your oven to 375°F (190°C). This ensures the casserole cooks evenly and the biscuits puff up perfectly.

Step 2: Prepare the Biscuit Base

Open the can of refrigerated biscuit dough and cut each biscuit into 4 equal pieces. Place them in a large mixing bowl.

Step 3: Mix with Sauce and Cheese

Pour the pizza sauce over the biscuit pieces in the bowl. Add 1 1/2 cups of shredded mozzarella, garlic powder, Italian seasoning, and any optional toppings like cooked sausage or vegetables. Gently toss everything together to coat the biscuit pieces evenly without squishing them.

Step 4: Assemble the Casserole

Grease a 9×13-inch baking dish with nonstick spray or butter. Pour the biscuit mixture into the dish, spreading it out evenly. Top with remaining mozzarella and all of the pepperoni slices. Sprinkle the Parmesan cheese over the top for added flavor and crispiness.

Step 5: Bake to Perfection

Place the casserole in the preheated oven and bake for 25 to 30 minutes. You’ll know it’s done when the biscuits have bubbled up and turned golden brown, and the cheese is melted and slightly crisp on top.

Step 6: Cool and Garnish

Once baked, let the casserole sit for 5 minutes before serving. Garnish with fresh chopped parsley for a pop of color and freshness.

Step 7: Serve and Enjoy

Use a large serving spoon to scoop generous portions onto plates. This dish pairs perfectly with a crisp side salad or garlic bread for a complete meal. Enjoy the cheesy, fluffy, pizza-filled goodness!

Notes

This Bubble Up Biscuit Pizza Casserole is incredibly adaptable to your family’s tastes. You can easily make it vegetarian by skipping the pepperoni and sausage and adding mushrooms, olives, or even spinach. If you’re a fan of spice, add a pinch of red pepper flakes or drizzle with hot honey before serving. Don’t skip letting the casserole rest after baking — it helps the structure set and makes serving easier.

Watch Out for These Mistakes While Cooking

• Overcrowding the baking dish: Cramming in too many biscuit pieces or toppings prevents even rising and bubbling.
• Undercooking the center: Always check the center biscuits with a knife or toothpick; they should not be doughy.
• Skipping pre-cooking meats or veggies: Raw sausage or watery vegetables can release too much moisture, making the casserole soggy.
• Using too much sauce: It can overwhelm the biscuit dough, preventing a proper rise and giving you a gummy texture.

Storage Instructions

Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, place portions in the microwave for 1–2 minutes or reheat in the oven at 350°F until warmed through. For best texture, avoid freezing — the biscuits can become mushy upon thawing. However, if you must freeze it, do so before baking and thaw overnight before cooking.
