Ingredients

12 ounces (340 grams) spaghetti pasta
1 pound (450 grams) ground beef or Italian sausage
1 small onion, finely chopped
3 cloves garlic, minced
24 ounces (680 grams) marinara or tomato sauce
1 teaspoon dried oregano
1 teaspoon dried basil
½ teaspoon red pepper flakes (optional)
1 cup (240 ml) ricotta cheese or cottage cheese

1 large egg

1 cup (100 grams) shredded mozzarella cheese

½ cup (50 grams) grated Parmesan cheese

Salt and freshly ground black pepper to taste

2 tablespoons olive oil (for sautéing)

Instructions

Preheat your oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish with butter or non-stick spray.
Cook the spaghetti in a large pot of salted boiling water according to package instructions until al dente (about 8-10 minutes). Drain and set aside.

While the pasta cooks, heat olive oil in a large skillet over medium heat. Add chopped onion and cook until translucent, about 3-4 minutes.
Add ground beef or sausage to the skillet. Cook until browned, breaking it apart with a spoon, about 5-7 minutes. Drain excess fat if necessary.
Stir in minced garlic, cook for another 30 seconds until fragrant. Add marinara sauce, oregano, basil, red pepper flakes (if using), salt, and pepper. Simmer for 5 minutes to let flavors meld.

In a small bowl, mix ricotta cheese with the egg until smooth. Season with a pinch of salt and pepper.
In a large mixing bowl, combine cooked pasta with the meat sauce. Add the ricotta mixture and stir well to evenly coat the pasta.
Transfer the pasta mixture into the prepared 9×9 baking dish. Spread evenly.

Sprinkle shredded mozzarella and grated Parmesan evenly over the top.
Bake uncovered in the preheated oven for 25-30 minutes, or until the cheese is bubbly and golden brown.
Remove from oven and let rest for 5 minutes before serving. Garnish with fresh basil or parsley if desired.

Tips

For a vegetarian version, substitute the meat with sautéed vegetables like zucchini, mushrooms, or bell peppers.
Use a high-quality marinara for richer flavor, or make your own fresh sauce for an even tastier dish.
If you prefer a creamier topping, add a dollop of ricotta or a splash of heavy cream before baking.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days or frozen for up to 2 months.

Serving Suggestions

Serve baked spaghetti hot, topped with extra Parmesan and fresh herbs. It pairs beautifully with a side of garlic bread, a crisp green salad, or steamed vegetables for a complete meal.

Variations

Cheesy Baked Spaghetti: Mix in additional shredded cheese like cheddar or provolone in the layers for extra gooeyness.

Spicy Baked Spaghetti: Add chopped jalapeños or a splash of hot sauce to the sauce for a spicy kick.
Meatless Version: Use hearty vegetables or plant-based meat substitutes to make it vegetarian or vegan (using vegan cheese).
White Baked Spaghetti: Replace tomato sauce with Alfredo sauce for a creamy, white version.

Storage and Reheating

Allow the baked spaghetti to cool completely before storing. In the refrigerator, it keeps well for up to 3 days in an airtight container. To reheat, microwave individual portions for 1-2 minutes or reheat in a 350°F (175°C) oven for 15-20 minutes until heated through. If reheating from frozen, thaw overnight in the fridge and then reheat as above. The dish maintains its texture and flavor best when eaten within this timeframe.

Frequently Asked Questions

Can I make baked spaghetti ahead of time?

Yes, you can prepare the assembled dish a day in advance. Cover it tightly with plastic wrap and refrigerate. When ready to bake, remove from the fridge and bake as directed, adding an extra 5-10 minutes if it’s cold from the fridge.

Can I freeze baked spaghetti?

Absolutely. Once cooled, wrap the dish tightly with plastic wrap and aluminum foil or transfer to a freezer-safe container. It can be frozen for up to 2 months. To reheat, thaw overnight in the fridge and bake at 375°F (190°C) for 25-30 minutes or until heated through.

Can I use fresh pasta instead of dried?

Fresh pasta cooks much faster, usually in about 2-3 minutes. If using fresh, cook until just tender, drain well, and proceed with the recipe. Keep in mind that fresh pasta may be softer, so handle gently when mixing and baking.

What cheese works best for the topping?

Mozzarella is the classic choice for a gooey, melty top, but you can mix in other cheeses like provolone, gouda, or cheddar for different flavors. Grated Parmesan adds a sharp, salty finish that complements the dish beautifully.

How do I prevent the cheese from burning?

To avoid burning, keep an eye on the bake time and consider covering the dish loosely with foil during the first 15-20 minutes if the cheese starts to brown too quickly. You can also lower the oven temperature slightly or move the rack to a lower position for more even cooking.

Is baked spaghetti suitable for gluten-free diets?

Yes, simply substitute regular spaghetti with gluten-free pasta. Ensure that all other ingredients, like sauces and cheeses, are gluten-free to keep the dish safe for those with gluten sensitivities.

Enjoy this comforting baked spaghetti recipe as a versatile, crowd-pleasing dish that offers both convenience and deliciousness in every bite.
