Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with olive oil or cooking spray.

Step 2: Prepare the Sauce

In a bowl, mix the marinara sauce, Italian seasoning, garlic powder, salt, black pepper, and red pepper flakes. This will enhance the flavor of the store-bought sauce and make it taste homemade.

Step 3: Assemble the Ravioli Bake

• Spread 1 cup of sauce on the bottom of the prepared baking dish.
• Arrange half of the ravioli in a single layer over the sauce.
• Sprinkle half of the chopped spinach over the ravioli.
• Add ½ cup of mozzarella cheese and ¼ cup of Parmesan cheese on top.
• Pour another 1 cup of sauce evenly over the layer.
• Repeat the layering process with the remaining ravioli, spinach, and cheeses.
• Pour the last bit of sauce over everything and sprinkle the remaining cheese on top.

Step 4: Bake the Dish

Cover the dish tightly with aluminum foil and bake for 25 minutes. This will allow the ravioli to cook through without drying out.

Step 5: Remove the Foil and Finish Baking

Uncover the dish and bake for another 10 minutes until the cheese is golden and bubbly. For an extra crispy top, broil for 2-3 minutes at the end.

Step 6: Serve and Enjoy

Remove from the oven and let it sit for 5 minutes before serving. Garnish with fresh basil and a drizzle of olive oil, then enjoy!
