A delightful casserole combining ravioli, seasoned beef, and fresh vegetables, baked to perfection with a cheesy topping.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking and optimal texture.
In a large skillet, cook the ground beef over medium heat until browned and no longer pink. Drain any excess fat.
Breaking the beef into small pieces as it cooks helps it cook evenly.
Add the garlic powder, salt, and black pepper to the cooked beef and stir well.
Adjust the seasoning to taste for a personalized flavor.
In a large saucepan, melt the butter over medium heat. Add the chopped onion and zucchini, and sauté until tender-crisp.
Stir frequently to prevent the vegetables from sticking to the pan.
Stir the spaghetti sauce into the cooked vegetables and heat through.
Warming the sauce helps blend the flavors together.
In a buttered 9x13 inch baking dish, spread a thin layer of the sauce mixture. Layer half of the ravioli, half of the beef, half of the remaining sauce, and half of the cheese.
Ensure even layers for consistent baking.
Repeat the layers with the remaining ingredients, omitting the cheese on the top layer.
Press down gently to compact the layers slightly.
Cover the dish with aluminum foil and bake in the preheated oven for 35 minutes.
Covering the dish prevents the top from drying out.
Uncover the dish, sprinkle the remaining cheese on top, and bake for an additional 10 minutes until the cheese is melted and bubbly.
For a golden crust, broil for the last 2 minutes.
Let the casserole rest for 10 minutes before serving.
Resting allows the layers to set, making it easier to serve.
