Ingredients
- 8 ounces (about 2 cups) of dried spaghetti
- 1 pound (16 ounces) ground beef or Italian sausage
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 24 ounces (about 3 cups) marinara or tomato sauce
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- ½ teaspoon red pepper flakes (optional)
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 2 large eggs
- ½ cup whole milk or heavy cream
- Salt and freshly ground black pepper to taste
- 1 tablespoon olive oil (for cooking)
Instructions
- Preheat your oven to 375°F (190°C). Grease an 8-inch baking dish with butter or non-stick spray and set aside.
- Cook the spaghetti in a large pot of salted boiling water until just al dente, about 8 minutes. Drain and set aside.
- While the pasta cooks, heat olive oil in a large skillet over medium heat. Add the chopped onion and cook until translucent, about 3-4 minutes. Add the minced garlic and cook for another 30 seconds until fragrant.
- Add the ground beef or sausage to the skillet. Cook until browned and cooked through, about 6-8 minutes. Break it apart with a spoon as it cooks. Season with salt, pepper, oregano, basil, and red pepper flakes if using.
- Pour in the marinara sauce and stir to combine. Let simmer for 5 minutes to meld flavors.
- In a small bowl, whisk together the eggs and milk or cream. Season with a pinch of salt and pepper.
- In a large mixing bowl, combine the cooked spaghetti, meat sauce, half of the shredded mozzarella, and the egg mixture. Mix well until all ingredients are evenly coated.
- Transfer the mixture to the prepared 8-inch baking dish. Smooth the top with a spatula.
- Sprinkle the remaining mozzarella and grated Parmesan cheese evenly over the top.
- Cover with foil and bake in the preheated oven for 20 minutes. Remove the foil and continue baking for an additional 10 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
- Substitutions: Use ground turkey or chicken for a leaner version, or plant-based protein for a vegetarian option. You can also swap out the marinara for a homemade tomato sauce for extra flavor.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven until steaming hot.
- Common mistakes: Overcooking the pasta can make the casserole too mushy; cook just until al dente. Also, ensure the cheese is evenly distributed for consistent melting and flavor.
- Additional tips: For a crispy top, broil the baked spaghetti for 1-2 minutes at the end, watching carefully to prevent burning.
Serving Suggestions
Serve your baked spaghetti with a fresh green salad dressed with vinaigrette or a side of garlic bread for a complete meal. It pairs well with roasted vegetables or a simple sautéed spinach for added greens.
Variations
For a different twist, try adding sautéed mushrooms, bell peppers, or olives into the meat sauce. You can also layer in slices of cooked zucchini or eggplant for extra vegetables. For a cheese lover’s version, mix in ricotta or shredded provolone for a richer, creamier casserole. To make it more filling, serve with a side of crusty bread or garlic knots.
Storage and Reheating
Leftover baked spaghetti can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and bake at 350°F (175°C) for about 20-25 minutes, or until heated through. Alternatively, microwave individual portions in 1-2 minute bursts, stirring in between, until hot. For best results, reheat gently to avoid drying out the dish or melting the cheese unevenly.
Frequently Asked Questions
Can I prepare baked spaghetti in advance?
Yes, you can assemble the casserole up to 24 hours ahead of time. Cover it tightly with plastic wrap or foil and refrigerate. When ready to bake, remove from the fridge and bake at 375°F for about 25-30 minutes, adding a few extra minutes if cold from the fridge.
Can I freeze baked spaghetti?
Absolutely. Let the baked spaghetti cool completely, then wrap it tightly with plastic wrap and aluminum foil. Freeze for up to 3 months. To reheat, thaw overnight in the refrigerator and bake at 375°F for 30-40 minutes until hot and bubbly.
What if I don’t have an 8-inch pan?
If your pan is slightly larger or smaller, adjust the cooking time accordingly. A slightly larger pan may require a few extra minutes, while a smaller pan may need less. Keep an eye on the cheese towards the end to prevent burning or drying out.
Can I make this dish vegetarian?
Yes, substitute the meat with chopped vegetables like zucchini, mushrooms, spinach, or eggplant. You can also add plant-based proteins or use vegetarian sausage. Just ensure that the sauce is flavorful enough to compensate for the absence of meat.
Is it necessary to cook the pasta before baking?
Yes, cooking the pasta beforehand ensures it’s perfectly al dente and prevents the casserole from becoming mushy. Do not overcook; just cook until slightly underdone, as it will continue to cook in the oven.
How do I prevent the cheese from burning on top?
To avoid burning, cover the casserole with foil during the initial baking period and remove it for the last 10 minutes to allow the cheese to brown. Keep a close watch if you choose to broil for extra crispiness.
