Step-by-Step Instructions:
1. Prepare the Meat Sauce
In a large skillet, cook the ground beef or sausage over medium heat until browned. Drain excess grease. Add the diced onion and minced garlic, cooking until fragrant. Stir in the marinara sauce, Italian seasoning, salt, and pepper. Simmer for 10 minutes.
2. Make the Cheese Mixture
In a bowl, mix together the cream cheese, ricotta, sour cream, garlic powder, and onion powder until smooth.
3. Layer the Casserole
- Preheat oven to 350°F (175°C).
- Grease a 9×13-inch baking dish.
- Spread half of the cooked spaghetti noodles in the dish and dot with butter slices.
- Spread the cheese mixture evenly over the noodles.
- Add the remaining spaghetti noodles on top.
- Pour the meat sauce over the noodles, spreading evenly.
- Sprinkle mozzarella and Parmesan cheese over the top.
4. Bake to Perfection
Cover with foil and bake for 30 minutes. Remove the foil and bake for another 10–15 minutes until the cheese is golden and bubbly.
5. Serve & Enjoy
Let the casserole rest for 10 minutes before slicing. Serve warm with garlic bread and a fresh salad for a complete meal.
