Ingredients
Method
- Boil spaghetti in salted water until just shy of al dente, about 8 minutes. Drain and set aside.
- Brown the ground beef in a skillet over medium-high, breaking it up, about 6 minutes. Add onion and cook 3 minutes, then garlic for 30 seconds. Stir in crushed tomatoes, oregano, 1/2 tsp salt, pepper, and sugar. Simmer 10 minutes.
- Mix ricotta, egg, remaining 1/2 tsp salt, and 1/4 cup Parmesan until smooth.
- Preheat oven to 375°F (190°C). Layer half the spaghetti, all the ricotta mixture, remaining spaghetti, meat sauce, then top with mozzarella and remaining 1/4 cup Parmesan in a 9x13-inch baking dish.
- Bake 20 minutes. Switch to broil and broil 2 to 3 minutes until golden and bubbling. Rest 5 minutes, then slice and serve.
Notes
The casserole needs 5 minutes to set after baking, so count that into your timing. If the top browns too fast under the broiler, tent loosely with foil and keep an eye on it.
