Pizza Casserole Recipe With Ground Beef: Cheesy Layers of Italian Flavor

This casserole brings all the flavors of pizza night to your dinner table in a one-dish format. I developed this recipe for busy weeknights when the family craves Italian comfort food without the fuss.

The ground beef is seasoned like pizza topping, then layered with pasta, marinara, and plenty of melted cheese. It bakes until bubbly and golden, with every bite delivering that familiar pizza taste we love.

What emerges from the oven is a satisfying meal that combines the heartiness of lasagna with the ease of a casserole. The layers meld together perfectly, creating a dish that’s both familiar and exciting.

Perfect for feeding a crowd or meal prepping for the week. This creation makes Italian night effortless.

Ingredients for Pizza Casserole Recipe with Ground Beef

Pantry staples and a few fresh items create this hearty one-dish meal.

The ground beef is the foundation—80/20 blend gives you the best flavor and juiciness. I grab mine from Costco for bulk savings, but any grocery store works. The pasta should be penne (those ridges hold sauce like a dream), but rotini or rigatoni work too. For the cheese, low-moisture mozzarella is key—it melts beautifully without turning greasy. Skip the pre-shredded stuff (it’s coated in anti-caking agents).

No pepperoni? Cooked Italian sausage or diced ham both work great. Out of Italian seasoning? Mix dried basil, oregano, and thyme at 1:1:1 ratio. The marinara can be jarred—Rao’s or Victoria are my go-tos. Want extra veggies? Toss in some diced bell peppers or mushrooms with the beef. The red pepper flakes can be skipped if the kids protest (or doubled if they don’t).

Assemble and bake right away, or prep ahead and refrigerate overnight. Leftovers keep for 4-5 days in the fridge, or freeze portions for up to 3 months. Reheats like a dream—just cover with foil to prevent the cheese from drying out.

Step-by-Step Instructions for Pizza Casserole With Ground Beef

Here’s how to build those irresistible cheesy layers with perfect texture every time.

Step 1: Brown the Ground Beef with Aromatics

Heat the 1 tbsp olive oil in a large skillet over medium-high heat. Add the 1.5 lb ground beef and break it up with a wooden spoon as it cooks. You want it to brown evenly, not steam, so don’t overcrowd the pan.

Once the beef starts to brown, sprinkle in the 1 tsp garlic powder, 1 tsp onion powder, 1 tsp salt, 0.5 tsp black pepper, 1 tbsp Italian seasoning, 1 tsp dried oregano, and 0.5 tsp red pepper flakes. Cook for another 2-3 minutes until the beef is fully browned with no pink remaining.

Drain off any excess fat, leaving just enough to coat the beef. This seasoned meat becomes the flavor base for your casserole, so don’t rush this step. The spices should smell fragrant and the beef should have a rich, savory aroma.

Step 2: Cook the Penne Pasta Al Dente

While the beef browns, bring a large pot of salted water to a rolling boil. Add the 12 oz penne pasta and cook according to package directions, but stop 1 minute short of the recommended time. You want it slightly underdone because it’ll finish cooking in the oven.

Drain the pasta well and return it to the pot. Pour in the 3 cups marinara sauce and the cooked ground beef, stirring to combine. The pasta should be well coated with sauce, but not swimming in it. This mixture forms the hearty middle layer of your casserole.

Step 3: Layer the Casserole with Cheese and Pepperoni

Preheat your oven to 375°F. In a greased 9×13-inch baking dish, spread half of the pasta mixture evenly across the bottom. Sprinkle 1.5 cups shredded mozzarella cheese over the pasta, then add half of the 3.5 oz pepperoni slices.

Repeat with the remaining pasta mixture, then top with the remaining 1.5 cups shredded mozzarella cheese and 1.5 cups shredded cheddar cheese. Arrange the rest of the pepperoni slices on top. The cheese should cover the pasta completely, with some pepperoni peeking through for visual appeal.

Step 4: Bake Until Bubbly and Golden

Bake uncovered for 20-25 minutes until the cheese is fully melted and starting to turn golden brown in spots. You’ll see the edges bubbling and the pepperoni slightly crisped at the edges. This is your visual cue that it’s done.

If the top isn’t browning enough, broil for 1-2 minutes at the end, watching closely to prevent burning. The casserole should be heated through with the cheese fully melted and slightly browned in places.

Let it rest for 5-10 minutes before serving. This allows the layers to set slightly, making it easier to serve neat portions. The rest also helps the flavors meld together for that perfect pizza casserole experience.

Creative Variations of These Flavors

Breakfast Pizza Bake

Swap the penne for 12 oz frozen hash browns (thawed) and add 6 beaten eggs mixed with ¼ cup milk between the layers. Top with 1 cup shredded cheddar and bake as directed. It’s like a hearty breakfast pizza that my daughter Lily requests for Sunday brunch. 🌟

Veggie-Packed Version

Add 1 cup diced bell peppers and 1 cup sliced mushrooms to the beef while browning. You can also stir in 2 cups fresh spinach to the pasta mixture before layering. I pick these up at the Portland farmers market—they add great texture and nutrients.

Spicy Kick Variation

Increase the red pepper flakes to 1 tsp and add ½ cup diced jalapeños to the beef. Use Pepper Jack cheese instead of cheddar for extra heat. Tom loves this version—it’s got just the right amount of bite without overwhelming the dish.

BBQ Pizza Twist

Replace the marinara with 2 cups BBQ sauce and swap the pepperoni for 1 cup cooked bacon bits. Top with 1 cup shredded Gouda for a smoky, tangy flavor. This reminds me of the BBQ chicken pizza I loved growing up in Cincinnati.

Taco Pizza Casserole

Season the beef with 1 packet taco seasoning instead of Italian herbs. Layer with 1 cup corn kernels and 1 cup black beans, then top with 1 cup shredded Monterey Jack. Serve with sour cream and salsa for a fun fusion meal.

Gluten-Free Option

Use 12 oz gluten-free penne and ensure all sauces and seasonings are certified gluten-free. The texture holds up well, and I’ve had great results with Barilla’s gluten-free pasta. No one will miss the regular version! 💛
