This dish is a winner in our house, I never have to worry about leftovers!

Servings: 6

12 oz spaghetti, cooked and drained
1 tablespoon olive oil
1/2 cup onion, chopped
2 garlic cloves, minced
1 pound ground beef
1 cup ranch dressing
1 cup sour cream
1 cup shredded cheddar cheese
1 cup mozzarella cheese, shredded
1/2 teaspoon salt
1/2 teaspoon black pepper
1/4 cup grated Parmesan cheese for topping

1. Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking dish.

2. In a large skillet, heat olive oil over medium heat. Add the chopped onion and minced garlic. Cook until onion is translucent and garlic is fragrant, about 3 to 5 minutes.

3. Add ground beef to the skillet. Cook until browned, breaking it apart with a spoon. Drain any excess fat.

4. In a large bowl, combine the cooked spaghetti, cooked ground beef, ranch dressing, sour cream, cheddar cheese, mozzarella cheese, salt, and pepper. Mix everything together well.

5. Transfer the spaghetti mixture to the prepared baking dish. Spread evenly and sprinkle Parmesan cheese over the top.

6. Bake uncovered in the preheated oven for 25 to 30 minutes, or until the casserole is bubbly and the top is golden brown.

7. Remove from oven and let sit for 5 minutes before serving to allow the casserole to set up a bit.
