Ingredients Overview
For the Spaghetti and Meat Sauce
- 1 pound spaghetti noodles
- 2 tablespoons olive oil
- 1 pound ground beef
- 1 medium onion, finely chopped
- 3 cloves garlic, minced
- 1 can crushed tomatoes (28 ounces)
- 2 tablespoons tomato paste
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- ½ teaspoon red pepper flakes (optional)
- Salt and black pepper to taste
- ½ cup chopped fresh parsley
The meat sauce is the heart of this casserole. Ground beef adds richness, while garlic, onions, and herbs build layers of flavor. Tomato paste helps deepen the sauce and gives it a restaurant-quality taste.
For the Cheese Layer
- 2 cups shredded mozzarella cheese
- 1 cup shredded cheddar cheese
- ½ cup grated Parmesan cheese
- 4 ounces cream cheese (optional for extra creaminess)
- ½ cup ricotta cheese (optional)
Using a mixture of cheeses creates the perfect balance of flavor and texture. Mozzarella provides stretch and creaminess, Parmesan adds a salty savory finish, and cheddar gives extra richness.
Step-by-Step Instructions
1. Prepare the Pasta
Begin by bringing a large pot of salted water to a boil. Cook the spaghetti according to package instructions until slightly firm, also known as al dente.
Avoid overcooking the pasta because it will continue cooking while baking in the oven. Once cooked, drain the spaghetti and set it aside.
Adding a small amount of olive oil can help prevent the noodles from sticking together while you prepare the sauce.
2. Make the Homemade Meat Sauce
Heat olive oil in a large skillet over medium heat. Add chopped onions and cook until they become soft and slightly golden.
Add minced garlic and cook for about 30 seconds until fragrant. Then add the ground beef and cook until browned, breaking it apart with a spoon as it cooks.
Drain excess fat if needed, then add crushed tomatoes, tomato paste, oregano, basil, salt, pepper, and red pepper flakes.
Allow the sauce to simmer for 15–20 minutes. This step allows the flavors to blend together and creates a rich, delicious sauce.
3. Combine Pasta and Sauce
Add the cooked spaghetti into the meat sauce and gently toss until every strand is coated.
This ensures that the pasta absorbs the flavors before baking. The sauce should evenly cover the noodles without making them too dry.
4. Layer the Casserole
Preheat your oven to 375°F (190°C).
Grease a large baking dish and add half of the spaghetti mixture. Spread a layer of cheese over the pasta, then add the remaining spaghetti.
Top the casserole with mozzarella, cheddar, and Parmesan cheese. The cheese layer will melt and create the beautiful golden topping seen in the dish.
5. Bake Until Golden and Bubbly
Cover the baking dish with foil and bake for about 20 minutes.
Remove the foil and continue baking for another 10–15 minutes until the cheese becomes golden brown and bubbly.
For an extra crispy top, you can place it under the broiler for 1–2 minutes while watching carefully.
Allow the casserole to rest for a few minutes before serving. This helps the layers set and makes slicing easier.
Expert Cooking Tips
- Cook the spaghetti slightly less than recommended because it will continue cooking in the oven.
- Use freshly shredded cheese for the smoothest melt and best flavor.
- Let the meat sauce simmer longer if you have time because slow cooking develops deeper flavors.
- Add vegetables like mushrooms, spinach, or bell peppers for extra nutrition.
- Prepare the casserole one day ahead for an easy dinner option.
