Ingredients
Scale
- 12 ounces spaghetti
- 1 tablespoon olive oil
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 1 pound ground beef
- 1 jar (24 ounces) marinara sauce
- 1 teaspoon Italian seasoning
- Salt and pepper, to taste
- 1/2 cup grated Parmesan cheese
- 2 cups shredded mozzarella cheese
- 1 egg
- 1/2 cup milk
- 1/4 cup chopped fresh parsley (optional for garnish)
Instructions
- Preheat Oven and Prepare Pasta:
- Preheat your oven to 350°F (175°C). Cook spaghetti according to the package instructions until al dente. Drain and return to the pot. Toss with olive oil to prevent sticking.
- Cook the Meat:
- In a large skillet over medium heat, cook the onion and garlic until softened, about 3-4 minutes. Add the ground beef, breaking it apart with a spoon, and cook until browned. Drain any excess fat.
- Combine Meat and Marinara Sauce:
- Stir the marinara sauce and Italian seasoning into the skillet with the beef. Season with salt and pepper to taste. Simmer for about 10 minutes.
- Mix Spaghetti and Sauce:
- Add the cooked spaghetti to the sauce and toss to combine. Transfer half of the spaghetti mixture to a greased 9×13-inch baking dish.
- Add Cheese Layer:
- Sprinkle half of the Parmesan and mozzarella cheeses over the spaghetti in the dish. Repeat layers with the remaining spaghetti mixture and cheeses.
- Prepare Egg Mixture:
- In a small bowl, whisk together the egg and milk. Pour this mixture evenly over the top layer of spaghetti.
- Bake:
- Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and lightly browned.
- Garnish and Serve:
- Let the baked spaghetti stand for a few minutes before serving. Garnish with chopped fresh parsley if desired.
