Why You’ll Love This Bubble Up Biscuit Pizza Casserole

It’s quick, it’s easy, and it’s packed with familiar, comforting flavors. The biscuits puff up and create soft, doughy layers that soak up all the saucy goodness while staying satisfyingly chewy in the center. This casserole is also endlessly customizable, whether you want to keep it classic with pepperoni or go all out with sausage, peppers, mushrooms, or olives. Perfect for picky eaters or family-style dinners, and even better as leftovers the next day.

What Kind of Biscuits Should I Use?

I recommend using standard refrigerated biscuit dough—the kind that comes in a can and is typically used for quick breakfasts. Pillsbury Grands or a store brand equivalent work well here. Avoid the flaky layered varieties, as they tend to separate too much and don’t hold up as nicely in the casserole. The classic buttermilk-style biscuits give you the best rise and that soft, tender interior that makes this dish irresistible.

Options for Substitutions

Not a fan of pepperoni? Swap it with cooked and crumbled Italian sausage or chopped cooked bacon for a smoky twist. Want to make it vegetarian? Skip the meat entirely and load up on sautéed mushrooms, bell peppers, onions, and black olives. You can also switch the marinara for a garlic white sauce or pesto for a totally different flavor profile. Cheese-wise, mozzarella is the go-to, but feel free to mix in provolone, cheddar, or even a sprinkle of parmesan for extra richness.

Ingredients for this Bubble Up Biscuit Pizza Casserole

Refrigerated Biscuit Dough
This is the base of the casserole. As it bakes, the biscuit pieces puff up and absorb the sauce, creating a soft, chewy, bread-like layer that “bubbles up” in the oven.

Pizza Sauce or Marinara Sauce
The rich, tomato-based sauce coats each piece of biscuit and brings in that unmistakable pizza flavor. Choose your favorite jarred brand or use homemade if you prefer.

Shredded Mozzarella Cheese
Melted mozzarella gives that stretchy, gooey, golden topping that every good pizza needs. It also helps hold everything together.

Pepperoni Slices
These crispy, salty rounds on top add classic pizza flavor. You can use mini or regular slices, or opt for turkey pepperoni for a lighter version.

Olive Oil or Nonstick Spray
Used to grease the baking dish so the casserole doesn’t stick.

Chopped Fresh Parsley or Basil (optional)
A sprinkle of herbs adds a fresh pop of color and flavor to the finished dish.

---

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with nonstick spray or olive oil to prevent sticking and ensure easy cleanup.

---

Step 2: Cut the Biscuits

Open your can of refrigerated biscuit dough and separate each biscuit. Use kitchen scissors or a knife to cut each biscuit into quarters. This helps them cook more evenly and allows the sauce and cheese to coat more surface area.

---

Step 3: Mix with Sauce

Place the biscuit pieces in a large mixing bowl. Pour the pizza or marinara sauce over them and toss until all the pieces are evenly coated in sauce.

---

Step 4: Layer in the Dish

Transfer the sauced biscuit pieces into the prepared baking dish, spreading them out evenly. Sprinkle a generous layer of shredded mozzarella cheese over the top.

---

Step 5: Add the Toppings

Lay the pepperoni slices over the cheese, covering the surface. You can add more toppings here if you like—think mushrooms, cooked sausage, or green peppers.

---

Step 6: Bake to Perfection

Place the dish in the preheated oven and bake for 30 to 35 minutes, or until the biscuits have puffed up and the cheese is melted and golden brown.

---

Step 7: Cool and Garnish

Let the casserole cool for about 5 minutes before serving. Sprinkle with chopped fresh parsley or basil for a fresh, herby finish.

How Long to Prepare the Bubble Up Biscuit Pizza Casserole

Prep Time: Most of the prep work is done in under 10 minutes. Cutting the biscuits, tossing them with sauce, and layering everything in the baking dish is quick and straightforward. If you’re using pre-sliced toppings like pepperoni, it goes even faster.

Cook Time: The casserole bakes for about 30 to 35 minutes in a 350°F oven. You’ll know it’s ready when the biscuits have puffed up, the edges are golden brown, and the cheese is melted and bubbling.

Tips for Perfect Bubble Up Biscuit Pizza Casserole

• Use regular buttermilk biscuit dough instead of flaky layers for the best texture.
• Don’t overload with sauce—just enough to coat the biscuit pieces evenly is ideal.
• For even baking, spread the biscuit pieces in a single layer with minimal overlapping.
• If the top is browning too quickly before the biscuits are done, cover the dish loosely with foil halfway through baking.
• Add a pinch of Italian seasoning or crushed red pepper flakes to the sauce for a flavor boost.

---

Watch Out for These Mistakes While Cooking

• Using too much sauce: Over-saucing can make the casserole soggy and prevent the biscuits from rising properly.
• Not cutting the biscuits small enough: Larger pieces may bake unevenly or stay doughy in the center.
• Underbaking: Make sure the biscuit pieces are cooked through. If you’re unsure, lift a piece from the center to check doneness.
• Crowding the toppings: Too many toppings can weigh down the biscuit layer and interfere with rising.
• Skipping the grease: A lightly greased dish ensures the bottom doesn’t stick and makes cleanup easier.
