🍕 Deep-Dish Pizza Casserole

Introduction

My kids call this “Pizza Casserole,” but honestly, it’s more like a deep-dish pizza dream in a baking dish! Flaky biscuits form a golden, buttery crust while seasoned ground beef, savory pepperoni, rich pizza sauce, and plenty of melted cheese come together for an easy dinner the whole family can enjoy.

It has all the comforting flavors of pizza without the need to make homemade pizza dough. It’s hearty, cheesy, budget-friendly, and perfect for busy weeknights when you want something filling and fun.

Ingredients

For the Casserole

• 1–2 packs flaky refrigerated biscuits, depending on the size of your baking dish
• 1 lb ground beef
• 1 pack pepperoni
• 1½–2 cups shredded mozzarella cheese
• 1 cup shredded cheddar cheese
• 1½ cups pizza sauce or marinara sauce
• ½ small onion, finely diced
• 2 cloves garlic, minced
• 1 teaspoon Italian seasoning
• ½ teaspoon garlic powder
• ½ teaspoon onion powder
• ¼ teaspoon black pepper
• Salt, to taste
• 1 tablespoon olive oil, if needed

Optional Toppings

• Extra pepperoni
• Sliced mushrooms
• Bell peppers
• Black olives
• Diced onions
• Cooked Italian sausage
• Jalapeños
• Parmesan cheese
• Crushed red pepper flakes

Instructions

Step 1: Prepare the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish or another deep casserole dish.

Step 2: Cook the Ground Beef

Place a large skillet over medium-high heat. Add the ground beef and diced onion.

Cook for about 6–8 minutes, breaking the beef apart with a spoon as it browns.

Drain excess grease if necessary.

Add the minced garlic, Italian seasoning, garlic powder, onion powder, black pepper, and a small amount of salt.

Cook for another minute until fragrant.

Remove from the heat.

Step 3: Prepare the Biscuit Crust

Open the refrigerated biscuits and separate them.

Cut each biscuit into halves or quarters, depending on their size.

Arrange the biscuit pieces across the bottom of the greased baking dish. Press them gently together so they create an even layer.

Don’t worry if there are small spaces—the biscuits will expand as they bake.

Step 4: Add the Pizza Sauce

Spread the pizza sauce evenly over the biscuit layer.

Try to cover most of the biscuits so every bite gets plenty of tomato flavor.

Step 5: Add the Beef

Spoon the seasoned ground beef evenly over the sauce.

Spread it all the way to the edges of the casserole.

Step 6: Add the Pepperoni

Arrange the pepperoni slices over the ground beef.

For an extra-pepperoni casserole, reserve a handful to place on top just before baking.

Step 7: Add the Cheese

Sprinkle the mozzarella and cheddar evenly over everything.

For the ultimate cheesy topping, add a few extra slices of pepperoni over the cheese.

Baking Method

Place the casserole in the preheated oven and bake for approximately 25–35 minutes, or until:

• The biscuits are fully cooked and golden around the edges.
• The cheese is melted and bubbling.
• The center is hot and cooked through.

If the cheese begins browning too quickly, loosely cover the dish with foil and continue baking.

Let the casserole rest for 5–10 minutes before serving. This allows the layers to settle and makes it easier to scoop.

The Formation of the Dish

The magic of this casserole comes from its layers.

First comes the flaky biscuit base, which becomes tender and golden as it bakes. Next comes the flavorful pizza sauce, followed by seasoned ground beef for a hearty, meaty layer.

Pepperoni adds that classic pizza flavor, while mozzarella and cheddar create a rich, gooey blanket of cheese on top.

As everything bakes together, the flavors blend into one comforting casserole that feels like a cross between homemade pizza and a hearty baked pasta-style dish—without the pasta!

A Little History

Pizza has roots stretching back centuries, with flatbreads topped with simple ingredients appearing in different cultures long before modern pizza became famous.

Modern pizza became especially associated with Naples, Italy, before spreading throughout the world. In the United States, pizza developed into countless regional styles, including thick and deep-dish versions.

Pizza casseroles take that familiar combination of sauce, meat, cheese, and toppings and turn it into an easy oven-baked family meal.

This biscuit-based version adds an American comfort-food twist by using refrigerated flaky biscuits instead of traditional pizza dough.

Tips for the Best Pizza Casserole

Use enough biscuits: If your baking dish is deep or large, you may need two packs.

Don’t overload the crust: Too many biscuits packed tightly together can make the center take longer to bake.

Drain the beef: Removing excess grease helps keep the casserole from becoming oily.

Use plenty of cheese: Mozzarella gives you the classic stretchy pizza texture, while cheddar adds extra flavor.

Let it rest: Give the casserole several minutes after baking before cutting or scooping.

Customize it: Add whatever pizza toppings your family loves.

For the Pizza Lovers ❤️

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 3–4 days.

To reheat, place individual portions in the microwave until hot, or warm them in a 350°F (175°C) oven until heated through.

For the best texture, reheating in the oven helps the biscuit crust become warm and slightly crisp again.
