Ingredients
- 1 lb spaghetti noodles
- 1 lb ground beef
- 1 small yellow onion diced
- 3 cloves garlic minced
- 1 24 oz jar marinara sauce
- 1 tsp Italian seasoning
- 1 tsp salt
- 1 tsp pepper
- 8 oz cream cheese softened
- 1 cup cottage cheese
- 1/2 cup sour cream
- 1 1/2 cups shredded mozzarella cheese divided
- 1/2 cup grated Parmesan cheese
- 4 tbsp butter sliced
Instructions
- Preheat the oven to 350°F and lightly grease a 9x13-inch baking dish. Cook the spaghetti according to the package directions until just al dente. Drain and set aside.In a large skillet over medium heat, cook the ground beef and diced onion until the beef is browned and the onion is tender. Drain any excess grease.
- Add the garlic and cook for about 30 seconds. Stir in the marinara sauce, Italian seasoning, salt, and pepper. Let the sauce simmer for 5 minutes.
- In a medium bowl, mix the softened cream cheese, cottage cheese, sour cream, 1/2 cup mozzarella, and Parmesan until well combined.
- Place the butter slices across the bottom of the prepared baking dish.
- Add half of the cooked spaghetti, then spread the creamy cheese mixture evenly over the noodles.
- Add the remaining spaghetti on top of the cheese layer. Pour the meat sauce evenly over the spaghetti and sprinkle the remaining 1 cup of mozzarella cheese over the top.
- Bake uncovered for 30–35 minutes, or until the casserole is hot and bubbly and the cheese is melted.
- Let the casserole rest for 5–10 minutes before slicing and serving. This gives the layers a little time to set and makes it easier to serve.
