Creating Baked Ravioli is simple when you follow these steps carefully:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Baking Dish: Grease a 9×13-inch baking dish with cooking spray or a little olive oil.
3. Layer Sauce: Spread half of the marinara sauce evenly across the bottom of the prepared baking dish.
4. Layer Ravioli: Arrange half of the ravioli over the sauce in a single layer.
5. Add Cheese Mixture: In a bowl, combine ricotta cheese, Italian seasoning, garlic powder, salt, and pepper. Spread half of this mixture over the ravioli layer.
6. Add More Sauce: Pour another layer of marinara sauce on top of the cheese mixture.
7. Repeat Layers: Layer the remaining ravioli on top, followed by the remaining ricotta mixture and then the remaining marinara sauce.
8. Top with Mozzarella: Sprinkle the shredded mozzarella cheese and grated Parmesan evenly over the top.
9. Cover with Foil: Cover the baking dish with aluminum foil to keep the moisture in during baking.
10. Bake: Place in the preheated oven and bake for 20 minutes.
11. Uncover and Brown: Remove the foil and continue to bake for an additional 5-10 minutes, or until the cheese is melted and bubbly.
12. Garnish: Remove from the oven and let it sit for a few minutes before garnishing with fresh basil leaves, if desired.
13. Serve: Cut into squares and serve warm.
