Cheesy Hamburger Casserole

Ingredients:

• 1 lb ground beef
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 teaspoon olive oil
• 1 can (14 oz) diced tomatoes, drained
• 1 can (8 oz) tomato sauce
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• Salt and pepper to taste
• 2 cups elbow macaroni, cooked al dente
• 2 cups shredded cheddar cheese
• 1 cup shredded mozzarella cheese
• 1/2 cup grated Parmesan cheese
• 1/2 cup sour cream
• Fresh parsley for garnish (optional)

Instructions:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Cook the Ground Beef: In a large skillet, heat olive oil over medium heat. Add chopped onions and garlic, sauté until softened. Add ground beef and cook until browned. Drain excess fat.
3. Season the Beef Mixture: Stir in diced tomatoes, tomato sauce, oregano, basil, salt, and pepper. Simmer for 10 minutes, allowing the flavors to meld.
4. Combine with Pasta: In a large mixing bowl, combine the cooked elbow macaroni with the beef mixture. Mix until well combined.
5. Add Cheeses: Fold in the cheddar, mozzarella, and Parmesan cheeses. Reserve a small amount of each cheese for topping.
6. Incorporate Sour Cream: Gently fold in the sour cream until evenly distributed, adding a creamy texture to the casserole.
7. Transfer to Casserole Dish: Grease a 9×13-inch casserole dish. Transfer the beef and pasta mixture into the dish, spreading it out evenly.
8. Top with Cheese: Sprinkle the reserved cheeses over the top of the casserole, creating a cheesy crust when baked.
9. Bake in the Oven: Bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly, and the edges are golden brown.
10. Serve: Remove from the oven and let it cool for a few minutes. Garnish with fresh parsley if desired. Serve warm and enjoy your delicious Cheesy Hamburger Casserole!
