Cheesy Beef Pizza Casserole

### Instructions:

#### Step 1: Prepare the Pasta
1. **Cook the Pasta**: Begin by cooking your pasta according to the package instructions. Drain and set it aside. It’s best to slightly undercook the pasta, as it will continue to cook in the oven during baking.

#### Step 2: Cook the Ground Beef and Vegetables
1. **Cook the Beef**: In a large skillet, heat a tablespoon of olive oil over medium heat. Add the ground beef and cook, breaking it up with a spatula, until browned and cooked through, about 5-7 minutes.
2. **Add Vegetables**: Once the beef is cooked, add the diced onion and bell pepper. Cook for an additional 3-4 minutes until the vegetables are softened and fragrant.
3. **Season the Meat**: Stir in the Italian seasoning, garlic powder, salt, and pepper to season the mixture. If you like, you can add a bit of red pepper flakes for a kick of heat.

#### Step 3: Assemble the Casserole
1. **Combine with Sauce**: Stir in the marinara sauce (or pizza sauce) into the beef and vegetable mixture, making sure it’s well combined. Let it simmer for a couple of minutes to meld the flavors together.
2. **Mix with Pasta**: In a large mixing bowl, combine the cooked pasta with the beef and sauce mixture. Stir to evenly coat the pasta with the sauce.
3. **Add Cheese**: Fold in the shredded mozzarella and cheddar cheese, saving a small amount of each for topping the casserole later.

#### Step 4: Bake the Casserole
1. **Transfer to a Baking Dish**: Pour the pasta and beef mixture into a greased 9×13-inch baking dish. Spread it out evenly.
2. **Top with Cheese**: Sprinkle the remaining mozzarella and cheddar cheese over the top of the casserole. For extra flavor, you can also sprinkle the grated Parmesan cheese on top.
3. **Bake**: Place the casserole in a preheated oven at 375°F (190°C) and bake for 20-25 minutes, or until the cheese is bubbly and golden brown. If you like your cheese extra crispy, you can broil the casserole for an additional 2-3 minutes, just keep an eye on it so it doesn’t burn.

#### Step 5: Serve and Enjoy
1. **Garnish**: Once the casserole is baked to perfection, remove it from the oven and let it rest for a few minutes before serving. If desired, sprinkle with fresh basil or additional Parmesan cheese for a burst of flavor.
2. **Serve**: Slice and serve the casserole hot! It’s great on its own or paired with a side salad and garlic bread for a full meal.
