A delightful and easy-to-make baked ravioli dish with a cheesy and spinach-filled twist.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking from the start.
Spread a thin layer of marinara sauce on the bottom of a 9x13 inch casserole dish.
This prevents the ravioli from sticking to the dish.
Arrange a single layer of frozen ravioli over the sauce.
No need to thaw the ravioli; they will cook perfectly in the oven.
Sprinkle half of the spinach over the ravioli, followed by half of the mozzarella and parmesan cheeses.
Distribute the cheese evenly for a consistent flavor.
Repeat the layers with the remaining ravioli, spinach, and cheeses.
Layering ensures every bite is flavorful.
Pour the remaining marinara sauce over the top and season with freshly ground black pepper.
Adjust the pepper to your taste preference.
Cover the dish with aluminum foil and bake for 30 minutes.
Covering helps retain moisture and cook the ravioli thoroughly.
Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden.
This step adds a delicious crust to the cheese.
Let the casserole rest for 5 minutes before serving.
Resting allows the layers to set for easier serving.
