Set the pan aside while you make the lasagna. Place a large skillet on the stove and turn the heat to medium. Put 1 pound (453 g) of ground beef into the skillet. Dice half of a sweet onion and add it to the skillet. Cook the meat until it's completely browned or until it reaches 170 degrees F (60 C). Drain off any fat. Stir the beef and onion mixture as it cooks to prevent it from sticking to the skillet. Open a 24-ounce (68 g) jar of marinara sauce and add it to the ground beef and onion. Stir in 2 cloves of minced garlic. Turn the heat down to medium-low. Stir the sauce occasionally and let it simmer for 5 minutes. Get out a medium mixing bowl. Place the cheese fillings and seasonings into it. Stir it until it's completely combined. You'll need to stir together:  2 cups (492 g) ricotta 1 large egg 1/4 cup (25 g) freshly grated Parmesan 1/4 cup (5 g) freshly chopped parsley 1 teaspoon garlic powder Spread one third of the meat sauce in the bottom of the prepared pan. Open one 25-ounce (708 g) package of frozen cheese ravioli and place a single layer of frozen ravioli over the sauce. Spread half of the ricotta filling over the ravioli and spread another third of the sauce over it. Arrange another layer of frozen ravioli and the rest of the ricotta filling over it. Spread the rest of the sauce on top. Sprinkle 2 cups (226 g) of grated mozzarella evenly over the top of the ravioli lasagna. Cover the pan with a sheet of aluminum foil and put it in the preheated oven. Bake the lasagna for 40 minutes. Carefully take the foil off of the pan. Bake the lasagna for 10 more minutes. This will give the cheese a chance to become golden brown and bubbly. Remove the ravioli lasagna from the oven and serve it once it's set for a few minutes. Consider serving the ravioli lasagna with extra chopped parsley.
