Meat Lovers Pizza Casserole
This cheesy meat lovers pizza casserole features tender pasta, savory Italian sausage, pepperoni, and crispy bacon baked under a blanket of bubbly mozzarella.
- Par-boiling the pasta keeps it al dente so it doesn't turn to mush during the bake.
- Rendering the sausage and bacon beforehand prevents a greasy pool from forming on top of the cheese.
- Freshly grated low-moisture mozzarella melts into a perfect, stretchy blanket without the powdery anti-caking agents found in pre-shredded bags.
My first apartment had a kitchen so small I could literally touch the refrigerator while standing at the stove, and it was there that I first tried to bake a pizza from scratch on a warped baking sheet.
The dough stuck, the sauce leaked, and my smoke detector screamed at me for forty-five minutes.
I cried.
Most pizza casseroles are a soggy, watery mess because home cooks dump raw sausage and wet pasta straight into a baking dish, hoping the oven will magically sort out the moisture.
When you bake starch in a high-moisture environment without par-boiling or properly draining your meats, the pasta absorbs the grease and excess water, destroying the protein matrix of the cheese and leaving you with a puddle of orange oil. I learned this the hard way after testing six different pasta-to-sauce ratios that all ended up looking like soup.
The simple fix is par-baking the pasta and browning the meats separately to render out the heavy fat before they ever touch the baking dish.
By using a sturdy pasta shape like rigatoni and tossing it with a concentrated marinara, we create a structural foundation that holds up under a heavy blanket of pepperoni, sausage, and bacon. If you love these flavors but want something a bit lighter, you might also enjoy our Pizza Cottage Cheese Bake.
Trust me on this one.
Your forearms will ache from grating the cheese by hand, but the result is absolutely perfect.
Meat Lovers Pizza Casserole
Ingredients
- 12 oz (340g) rigatoni pasta
- 1 tbsp olive oil
- 1 lb (450g) mild Italian sausage, casings removed
- 1/2 cup pepperoni slices, chopped, plus more for topping
- 6 strips thick-cut bacon, chopped
- 1 small yellow onion, finely diced
- 3 cloves garlic, minced
- 2 cans (24 oz total) high-quality marinara sauce
- 1 tbsp Diamond Crystal kosher salt
- 1 tsp dried oregano
- 1/2 tsp red pepper flakes
- 3 cups (340g) low-moisture mozzarella cheese, freshly grated
- 1/2 cup (50g) Parmesan cheese, freshly grated
Directions
- Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with cooking spray or a light rub of olive oil.
- Bring a large pot of salted water to a rolling boil. Cook the pasta for 2 minutes less than the package directions for al dente, then drain and set aside.
- In a large skillet over medium-high heat, cook the chopped bacon until crispy, then fish it out with a slotted spoon and let it drain on paper towels.
- In the same skillet with a tablespoon of bacon fat left behind, brown the Italian sausage, breaking it up with a wooden spoon until fully cooked, then drain any excess grease.
- Stir in the diced onions and minced garlic, cooking for 3 minutes until soft and fragrant.
- Turn off the heat, then stir in the marinara sauce, dried oregano, red pepper flakes, cooked pasta, chopped pepperoni, and half of the cooked bacon.
- Transfer half of the pasta mixture into the prepared baking dish, then sprinkle with half of the mozzarella and Parmesan cheeses.
- Layer the remaining pasta mixture on top, then cover with the remaining mozzarella, Parmesan, whole pepperoni slices, and the rest of the crispy bacon.
- Bake uncovered for 25 to 30 minutes, or until the cheese is melted, golden brown, and bubbling at the edges. Let it rest for 10 minutes before serving. </
Notes
- I highly recommend using Diamond Crystal kosher salt for boiling the pasta; if you only have Morton's kosher salt, cut the volume by half to avoid over-salting.
- Low-moisture mozzarella is essential here because its lower water content prevents the cheese from releasing excess liquid and breaking the sauce's emulsion.
- Keep a close eye on the casserole during the last 5 minutes of baking; the high fat content of the pepperoni can cause the top to transition from golden to burnt very quickly.
- After a day in the fridge, the pasta will absorb more of the sauce, making the casserole denser but even more flavorful when reheated.
- If you want a truly crispy top, you can broil the casserole for 1 to 2 minutes at the very end, but tap your tongs against your hip and stay right by the oven door to prevent disaster.
Serving Suggestions
Complete this comforting meal by pairing it with fresh, vibrant sides that cut through the rich, cheesy layers of the pasta bake.
- A crisp green salad tossed with our Homemade Italian Dressing to balance the savory meats.
- Warm, buttery garlic bread or Garlic Butter Dinner Rolls for scooping up extra sauce.
- A side of Balsamic grilled vegetables with a touch of garlic flavor to add a smoky, sweet contrast.
- A light, refreshing dessert like fresh fruit salad to cleanse the palate afterward.
Storage and Reheating
Let the casserole cool completely before storing.
Transfer any leftovers into an airtight container and keep them in the refrigerator for up to four days. The flavors actually meld together beautifully overnight, making day-two lunch something to look forward to.
To reheat, place a portion in an oven-safe dish, splash a teaspoon of water over the top, and cover it tightly with foil.
Bake at 350°F (175°C) for about 15 minutes until the cheese is melted and hot throughout. Avoid using the microwave if you can, as it tends to make the pepperoni rubbery and separates the oil from the cheese.
Ingredient Substitutes
If you need to swap ingredients based on what is currently in your pantry, here are the best tested alternatives.
- Pasta: Penne, cavatappi, or even rotini work beautifully in place of rigatoni. If you prefer a classic layered pasta, you can try our Cheesy Baked Rigatoni with Ground Beef.
- Meats: Swap the pork sausage for sweet Italian turkey sausage or ground beef to lighten the dish. If you have leftover pepperoni, save them to make Pepperoni Pizza Rolls later in the week.
- Cheese: Provolone or Monterey Jack can be substituted for half of the mozzarella if you want a different melt profile.
- Sauce: A rich marinara is best, but you can use a garlic-herb tomato sauce or even a homemade marinara if you have the time. For a fun skillet alternative, check out our Cast Iron Skillet Pizza.
This casserole is the ultimate comfort food that brings everyone to the table with smiles on their faces. It is warm, incredibly satisfying, and forgiving enough for even the busiest weeknights.
