Instructions:
- Cook the pasta:
- In a large pot of salted boiling water, cook the pasta according to the package instructions until al dente. Drain and set aside.
- Prepare the beef mixture:
- In a large skillet, cook the ground beef over medium heat until browned and fully cooked, about 6-8 minutes.
- Add the chopped onion and garlic to the beef and sauté until softened, about 2-3 minutes.
- Stir in the diced tomatoes (with juice), tomato sauce, Italian seasoning, salt, and pepper. Simmer for 5-7 minutes, allowing the flavors to meld together.
- Combine ingredients:
- Preheat your oven to 350°F (175°C).
- In a large bowl, combine the cooked pasta, beef mixture, sour cream, and 1 ½ cups of the shredded cheddar cheese. Stir until well combined.
- Assemble the casserole:
- Transfer the pasta and beef mixture into a greased 9×13-inch baking dish.
- Sprinkle the remaining cheddar cheese and the mozzarella cheese evenly on top.
- Bake:
- Bake in the preheated oven for 20-25 minutes, or until the cheese is melted, bubbly, and slightly golden on top.
- Garnish and serve:
- Remove from the oven, let the casserole rest for a few minutes, then garnish with chopped fresh parsley if desired.
- Serve hot and enjoy this cheesy, comforting beef casserole!
Tips:
- You can add vegetables like bell peppers, spinach, or mushrooms to the beef mixture for extra flavor and nutrition.
