Prepare the Meat Sauce
- Heat olive oil in a large skillet or Dutch oven over medium-high heat. Add ground beef and cook, breaking it up with a spoon, until browned and cooked through, about 5-7 minutes. Drain any excess fat.
- Reduce heat to medium. Add chopped yellow onion to the skillet and cook until softened, about 3-4 minutes. Stir in minced garlic, tomato paste, dried oregano, dried basil, and red pepper flakes (if using). Cook for 1 minute more until fragrant.
- Pour in crushed tomatoes and water. Stir well to combine. Bring the sauce to a simmer, then reduce heat to low, cover, and let it gently simmer for at least 15 minutes, or up to 30 minutes, stirring occasionally. Season with salt and black pepper to taste.
Prepare the Ricotta Mixture
- While the sauce simmers, in a large mixing bowl, combine the ricotta cheese, large egg, 1/2 cup grated Parmesan cheese, chopped fresh parsley, 1/4 tsp salt, and 1/8 tsp black pepper. Mix thoroughly until well combined.
Assemble the Casserole
- Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
- Spread about 1 cup of the meat sauce evenly over the bottom of the prepared baking dish.
- Arrange half of the frozen ravioli in a single layer over the sauce. Do not overlap too much.
- Carefully dollop half of the ricotta mixture over the ravioli, gently spreading it with the back of a spoon.
- Top the ricotta layer with about 1.5 cups of the meat sauce, spreading it evenly.
- Sprinkle 1 cup of shredded mozzarella cheese over the sauce.
- Repeat the layers: remaining half of the frozen ravioli, remaining ricotta mixture, and remaining meat sauce.
- Finish by sprinkling the remaining 1 cup of shredded mozzarella cheese and an additional sprinkle of Parmesan cheese (if desired) over the top.
Bake and Serve
- Cover the baking dish tightly with aluminum foil. Bake for 25 minutes.
- Remove the foil and bake for an additional 10-15 minutes, or until the casserole is bubbly and the cheese on top is melted and lightly golden. For an extra golden-brown crust, you can carefully broil for 1-2 minutes at the end, watching closely to prevent burning.
- Remove the casserole from the oven and let it rest for 10-15 minutes before serving. This allows the layers to set and makes for easier slicing.
- Garnish with fresh parsley, if desired, and serve hot.
Notes
For an even richer flavor, you can use a mix of ground beef and Italian sausage for the meat sauce.
Ensure your meat sauce is quite fluid when assembling, as the frozen ravioli will absorb a lot of moisture as it cooks. If it's too thick, add a little more water or broth.
Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat in the oven or microwave.
