INGREDIENTS
- 1 pound (16 oz) pasta (penne, rotini, or ziti work best)
- 1 pound ground beef or Italian sausage
- 1 medium onion, diced
- 2-3 cloves garlic, minced
- 1 green bell pepper, chopped (optional)
- 2 cups pizza sauce or marinara sauce
- 1 teaspoon Italian seasoning
- 1/2 teaspoon red pepper flakes (optional, for heat)
- 2 cups shredded mozzarella cheese
- 1 cup shredded parmesan cheese
- 3-4 oz pepperoni slices
- 1/4 cup sliced black olives (optional)
- 1/4 cup sliced mushrooms (optional)
- Fresh basil for garnish (optional)
- Salt and pepper to taste
INSTRUCTIONS
Preheat your oven to 350°F (175°C) and lightly grease a 9×13 inch baking dish with cooking spray or olive oil.
Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente, usually 8-10 minutes. Be careful not to overcook as the pasta will continue to soften in the oven. Drain well and set aside.
While the pasta is cooking, heat a large skillet over medium-high heat. Add the ground beef or Italian sausage and cook until browned, breaking it up with a wooden spoon as it cooks, about 5-7 minutes. If there’s excess fat, drain it off.
Add the diced onion and bell pepper to the meat and cook until softened, about 3-4 minutes. Add the minced garlic and cook for another 30 seconds until fragrant. Season with salt, pepper, Italian seasoning, and red pepper flakes if using.
Pour the pizza sauce into the skillet with the meat mixture and stir to combine. Let it simmer for 2-3 minutes to allow the flavors to meld together. Remove from heat.
In the prepared baking dish, combine the cooked pasta and the meat sauce mixture. Stir gently to ensure the pasta is evenly coated with sauce.
Sprinkle half of the mozzarella cheese over the pasta mixture. Add your optional toppings like mushrooms and olives, reserving some pepperoni for the top. Then cover with the remaining mozzarella and parmesan cheese. Arrange the remaining pepperoni slices on top.
Cover the baking dish with aluminum foil and bake for 20 minutes. Then remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and starting to brown at the edges.
Allow the casserole to rest for 5-10 minutes before serving. This helps the casserole set and makes it easier to portion. Garnish with fresh basil if desired, and serve hot.
