Description

A comforting, oven-baked Italian-style spaghetti casserole layered with rich tomato sauce, savory sausage or ground beef, gooey melted cheese, and aromatic herbs—perfect for family dinners.


Ingredients

Units Scale
  • 12 oz (340 g) spaghetti
  • 1 lb (450 g) Italian sausage or ground beef
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • 24 oz (680 g) marinara sauce
  • 1 cup ricotta cheese
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 1 tsp dried oregano
  • 1 tsp dried basil
  • 1 tbsp olive oil
  • Salt and pepper, to taste

Instructions

  1. Preheat oven to 375 °F (190 °C). Lightly grease a 9×13‑inch baking dish.
  2. Cook spaghetti according to package instructions until al dente. Drain and set aside.
  3. Heat olive oil in a skillet over medium heat. Add onion and garlic; sauté until softened, about 3 minutes.
  4. Add sausage or beef, breaking it up with a spoon. Cook until browned and cooked through. Season with salt, pepper, oregano, and basil.
  5. Stir in marinara sauce and simmer for 5 minutes.
  6. In a large bowl, combine cooked spaghetti with ricotta cheese and half of the mozzarella.
  7. Spread half the spaghetti mixture into the baking dish. Top with meat sauce layer.
  8. Layer the remaining spaghetti mixture on top, then sprinkle with remaining mozzarella and Parmesan cheese.
  9. Bake uncovered for 20–25 minutes, until cheese is melted and bubbly and edges are slightly browned.
  10. Let cool for 5 minutes before slicing and serving.

Notes

  • Swap ricotta for cottage cheese or crème fraîche if preferred.
  • Use gluten‑free pasta to make it gluten‑free.
  • Make ahead: assemble, cover, and refrigerate up to 24 hours before baking (add a few extra minutes to baking time).
  • Leftovers keep well in the fridge for up to 4 days—reheat in the oven or microwave until warmed through.
  • Add a layer of sautéed spinach or mushrooms for extra veggies.
