Heat your large skillet over medium-high heat. Add the ground beef and cook until brown. Use a spoon to break it into small bits.

Stir in the minced garlic and the Italian seasoning. Add the salt and the black pepper to meat. Cook for two more minutes until it smells good.

Pour the marinara sauce into the skillet with meat. Stir everything together and let it simmer for a bit. This creates a very rich and meaty sauce.

Spread one cup of the meat sauce in the dish. This prevents the frozen pasta from sticking to bottom. Make sure the layer is thin and even.

Place half of the frozen ravioli over the sauce. Arrange them in a single layer if you can. It helps the pasta cook very evenly in oven.

Pour half of the remaining sauce over the ravioli. Sprinkle one cup of the mozzarella cheese on top. This makes a cheesy layer in the middle.

Add the rest of the ravioli and the sauce. Top the dish with the rest of the mozzarella. Add the Parmesan cheese over everything for extra flavor.

Preheat your oven to 375 degrees Fahrenheit. Cover the dish with foil and bake 20 minutes. Remove foil and bake 15 more minutes until bubbly.
