Preheat your oven to 375°F (190°C).
In a skillet, cook the ground beef over medium heat until browned. Drain excess fat.
Add minced garlic and Italian seasoning to the beef. Cook for another 2 minutes.
In a baking dish, spread a thin layer of marinara sauce on the bottom.
Layer half of the ravioli over the sauce. Top with half of the beef mixture, half of the remaining marinara sauce, and half of the mozzarella cheese.
Repeat the layers with the remaining ravioli, beef mixture, marinara sauce, and mozzarella cheese. Sprinkle Parmesan cheese on top.
Cover the baking dish with aluminum foil and bake for 20 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden.
Let it cool for a few minutes before serving. Enjoy!
