Ingredients:
- 2 Tbsp olive oil
- 1 medium yellow onion, finely diced
- 3 cloves garlic, minced
- 1 lb lean ground beef (or Italian sausage)
- 2 Tbsp tomato paste
- 1 (28 oz) can crushed tomatoes (800g)
- 1 tsp dried oregano
- 1 tsp dried basil
- Salt and black pepper, to taste
- 2 (20 oz) bags fresh or frozen ravioli (1.1 kg), cheese or beef filling (do not cook)
- 1 cup whole milk ricotta cheese (240g)
- 1/4 cup fresh parsley, chopped
- 3 cups shredded mozzarella (360g)
- 1/2 cup grated Parmesan cheese (60g)
Instructions:
- Preheat the oven to 375°F (190°C). Lightly grease a 9x13 inch (23x33 cm) baking dish.
- Heat olive oil in a large skillet over medium heat. Add the diced onion and sauté until softened and translucent (about 5–7 minutes). Add minced garlic and cook for 1 minute until fragrant.
- Add the ground beef or sausage to the skillet. Break it up and cook thoroughly until no pink remains. Drain off any excess fat from the pan.
- Stir in the tomato paste and cook for 2 minutes, allowing it to caramelise slightly. Pour in the crushed tomatoes. Stir in dried oregano, basil, salt, and pepper. Bring to a low simmer, then reduce heat and cook for 10 minutes to allow the flavors to deepen.
- While the sauce simmers, combine the ricotta cheese, half of the fresh parsley, and a pinch of salt and pepper in a small bowl. Set aside.
- Spread about 1.5 cups (360 ml) of the meat sauce evenly over the bottom of the prepared baking dish.
- Arrange half of the uncooked ravioli over the sauce in a single layer.
- Dollop spoonfuls of the ricotta mixture over the ravioli layer.
- Pour another 1.5 cups of sauce over the ricotta and pasta. Sprinkle half of the shredded mozzarella over this layer.
- Add the remaining ravioli, followed by the rest of the sauce.
- Top the casserole with the remaining mozzarella and the grated Parmesan cheese.
- Cover the dish tightly with aluminium foil. Bake for 15 minutes (this allows the ravioli to steam and cook through).
- Remove the foil and bake for another 15–20 minutes, or until the sauce is bubbly and the cheese is golden brown and starting to crisp around the edges.
- Allow the casserole to rest on the counter for 5 minutes before slicing and serving. Garnish with the remaining fresh parsley.
