Preheat Oven: Preheat your oven to 375°F (190°C).

Cook Ravioli: If using frozen ravioli, cook them according to package instructions until al dente. Drain well.

Prepare Ground Beef Mixture:

• Heat 1 tablespoon of olive oil in a large skillet over medium heat.
• Add the chopped onion and cook until softened, about 3-4 minutes.
• Add the minced garlic and cook for another 1-2 minutes, until fragrant.
• Add the ground beef and cook until browned, breaking it up with a spoon as it cooks. Season with salt and pepper to taste.
• Drain any excess fat from the skillet.

Prepare Baking Dish: Lightly grease a 9x13 inch baking dish with olive oil.

Layer Ingredients:

• Spread a thin layer of marinara sauce on the bottom of the baking dish.
• Arrange a single layer of ravioli over the sauce.
• Spoon some of the ground beef mixture over the ravioli.
• Spoon some marinara sauce over the beef and ravioli.
• Add dollops of ricotta cheese, if using.
• Sprinkle with mozzarella and Parmesan cheese.
• Repeat the layers until all the ingredients are used, finishing with a layer of sauce and a generous topping of mozzarella and Parmesan cheese.

Add Breadcrumbs: If using breadcrumbs, sprinkle them on top and drizzle with a little olive oil for a crunchy topping.

Bake:

• Cover the dish with foil and bake in the preheated oven for 20 minutes.
• Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden brown.

Garnish: Remove from the oven and let it cool slightly. Garnish with chopped fresh basil, if desired.

Serve: Serve hot, enjoying the melty, cheesy goodness.
