Ingredients
Serves: 6–8 people
• 1 pound ground beef • 1 pound spaghetti • 4 tablespoons butter • 1 medium yellow onion, finely diced • 4 cloves garlic, minced • 1 can (28 ounces) crushed tomatoes • 1 can (6 ounces) tomato paste • 2 teaspoons dried Italian seasoning • 1 teaspoon dried oregano • 1/2 teaspoon dried basil • 1 teaspoon salt • 1/2 teaspoon black pepper • 1/4 teaspoon red pepper flakes (optional) • 2 cups ricotta cheese • 2 cups shredded mozzarella cheese, divided • 1/2 cup grated Parmesan cheese • 1 large egg • 1/4 cup fresh parsley, chopped • 1 tablespoon olive oil
Step-by-Step Instructions
- Preheat your oven to 375 degrees Fahrenheit and position a rack in the center of the oven.
- Bring a large pot of salted water to a rolling boil and add your spaghetti, cooking according to package directions until just al dente.
- Drain the cooked pasta and toss it lightly with olive oil to prevent sticking, then set it aside.
- In a large skillet over medium-high heat, add the ground beef and break it apart with a wooden spoon as it cooks for 6–8 minutes until deeply browned and cooked through.
- Drain off excess fat from the skillet, leaving about 1 tablespoon of the rendered beef fat behind.
- Reduce the heat to medium and add the butter to the skillet with the cooked beef.
- Add the diced onion and cook for about 4–5 minutes, stirring occasionally, until it becomes soft and translucent.
- Stir in the minced garlic and cook for another 30 seconds to 1 minute until fragrant but not browned.
- Add the crushed tomatoes, tomato paste, Italian seasoning, oregano, basil, salt, black pepper, and red pepper flakes, stirring well to combine.
- Let the sauce simmer gently over medium-low heat for about 10–15 minutes, stirring occasionally, to allow the flavors to meld together.
- While the sauce simmers, prepare the cheese mixture by combining the ricotta cheese, 1 cup of the mozzarella cheese, Parmesan cheese, egg, and fresh parsley in a large mixing bowl.
- Stir the cheese mixture until everything is well combined and smooth.
- In a 9-by-13-inch baking dish, spread a thin layer of the meat sauce on the bottom, using about 1 cup of sauce.
- Add half of the cooked spaghetti over the sauce in an even layer.
- Spread half of the cheese mixture evenly over the spaghetti layer.
- Add another layer of meat sauce, using about 1.5 cups, over the cheese.
- Layer the remaining spaghetti over the sauce in an even layer.
- Spread the remaining cheese mixture evenly over the top layer of spaghetti.
- Pour the remaining meat sauce over the cheese layer, spreading it gently and evenly.
- Sprinkle the reserved 1 cup of mozzarella cheese over the top layer of sauce, covering the entire casserole.
- Cover the baking dish tightly with aluminum foil and place it in the preheated oven.
- Bake covered for about 25–30 minutes until the casserole is heated through and bubbling around the edges.
- Remove the foil and bake for an additional 15–20 minutes until the top is golden brown and the cheese is melted and bubbly.
- Remove the casserole from the oven and let it rest for 5–10 minutes before serving, which allows it to set slightly and makes it easier to cut clean portions.
The Art of Layering
The secret to a successful baked spaghetti casserole lies in understanding how to layer ingredients strategically for maximum flavor and texture. First, starting with a thin layer of sauce on the bottom prevents the pasta from sticking to the dish while creating a flavorful foundation. Next, alternating layers of pasta, cheese, and sauce ensures that every forkful contains all the delicious components rather than getting mostly pasta or mostly sauce. Additionally, finishing with mozzarella cheese on top creates that beautiful golden crust that makes this casserole so visually appealing and deeply satisfying. Meanwhile, letting the casserole rest after baking allows the layers to set slightly, making it infinitely easier to serve clean portions that hold together beautifully instead of falling apart.
Serving and Storing Tips
Serving Suggestions
Serve this baked spaghetti casserole with a crisp green salad dressed with lemon vinaigrette to cut through the richness and provide a fresh contrast to all that melty cheese. Garlic bread is practically essential on the side, both for soaking up extra sauce and for adding textural contrast to the soft, cheesy pasta. For a complete Italian-inspired meal, add roasted vegetables like broccoli, zucchini, or bell peppers either mixed into the casserole or served alongside on the plate. A simple mixed green salad with a tangy balsamic vinaigrette pairs beautifully with the richness of this dish, providing brightness and balance. Additionally, if you’re serving guests, a small handful of fresh basil or parsley scattered on top just before serving adds color, freshness, and a touch of elegance. For family meals, simply let everyone serve themselves straight from the baking dish, and have extra Parmesan cheese available for those who want additional flavor.
Storage Tips
Refrigerate leftovers in an airtight container for up to 3 days, and you’ll find the flavors actually improve as the ingredients continue to meld together overnight. To reheat, place portions in a covered oven-safe dish and warm at 350 degrees Fahrenheit for about 15–20 minutes until heated through, which preserves the texture better than microwaving. Freezing works beautifully with this casserole—cool it completely, then cover it tightly with plastic wrap followed by aluminum foil and freeze for up to 3 months. When ready to serve, thaw overnight in the refrigerator, then bake covered at 375 degrees Fahrenheit for about 35–40 minutes until heated through and bubbling at the edges. Alternatively, you can bake the casserole directly from frozen, though you’ll need to add 20–30 minutes to the total baking time and keep it covered with foil for the first 45 minutes to allow it to thaw and heat evenly.
Helpful Notes and Tips
One common mistake home cooks make is overcooking the pasta before adding it to the casserole, which causes it to become mushy and fall apart during baking. Instead, cook your pasta until it’s just barely al dente, knowing that it will continue cooking in the oven as the casserole bakes. Additionally, don’t skip the step of draining excess fat from the meat—doing so prevents the casserole from becoming too greasy and heavy.
For a lighter version of this dish, use ground turkey or lean ground beef instead of regular ground beef, which reduces the fat content while maintaining the hearty, satisfying character. To make this recipe vegetarian, simply omit the ground meat and add an extra cup of sautéed mushrooms, spinach, or zucchini to the sauce for substance and flavor. Next, if you don’t have ricotta cheese on hand, you can substitute it with cottage cheese, which has a similar texture and works beautifully in this casserole.
Meanwhile, the cheese mixture is flexible—you can adjust the ratio of ricotta to mozzarella based on your preference for creaminess versus stringiness. If you prefer a more robust tomato flavor, add another can of crushed tomatoes or increase the tomato paste by a tablespoon. Furthermore, fresh herbs elevate this dish dramatically, so if you have fresh basil, oregano, or parsley on hand, add them to the cheese mixture or scatter them on top before serving.
For extra flavor depth, brown the ground meat and let it rest briefly before adding the onions, which develops deeper, more complex flavors through caramelization. Additionally, if you want a spicier casserole, increase the red pepper flakes or add diced hot peppers to the sauce. If your sauce seems too thick after simmering, simply stir in a splash of beef broth or water to reach your desired consistency before assembling the casserole.
If you’re preparing this casserole ahead of time, assemble it completely, cover it tightly with plastic wrap, and refrigerate for up to 24 hours before baking—this is actually beneficial as it allows the flavors to develop and the noodles to absorb some of the sauce. When baking a refrigerated casserole, add about 10 minutes to the covered baking time to account for the colder starting temperature.
Chef Tips
Don’t skip the resting period after baking, as those 5–10 minutes allow the casserole to set and hold together beautifully when portioned rather than falling apart or being soupy. Additionally, for a more rustic presentation, grate the cheese fresh from a block just before assembling the casserole, which melts more smoothly and evenly than pre-shredded cheese that contains anti-caking agents.
Frequently Asked Questions
Can I use ground turkey or another meat instead of ground beef? Absolutely—ground turkey, ground chicken, ground pork, or even Italian sausage all work wonderfully and create delicious variations with different flavor profiles.
How do I know when the casserole is done baking? The casserole is done when the cheese on top is melted and golden brown, the sauce is bubbling around the edges, and a fork inserted into the center comes out hot.
Can I prepare this casserole the night before? Yes, you can assemble it completely, cover it tightly with plastic wrap, and refrigerate for up to 24 hours before baking, which actually helps flavors develop.
