Preheat your oven to 350°F (175°C). In a large skillet, cook the ground beef with Italian seasoning and garlic powder over medium heat. Break it up as it cooks. Once browned and no longer pink, drain the excess grease.
In an 8x8-inch baking dish, spread ⅓ of the pasta sauce on the bottom.
Layer half of the frozen ravioli on top of the sauce.
Sprinkle half of the cooked beef over the ravioli. Top with ½ cup of mozzarella cheese.
Pour another ⅓ of the sauce over the cheese.
Top with the remaining ½ cup of cheese. Cover with foil and bake for 45–55 minutes, or until the cheese is melted and bubbly.
Remove from the oven and let it sit for a few minutes before serving.
Optional: Garnish with chopped fresh parsley.
