Necessary Kitchen Equipment

9×13-inch baking dish
Large skillet
Mixing bowl
Spoon or spatula

Ingredients

For the Casserole:

1 (20-ounce) package cheese ravioli (fresh or frozen)
2 cups fresh spinach, roughly chopped
2 cups mushrooms, sliced
2 cups shredded mozzarella cheese
½ cup grated Parmesan cheese
2 cups marinara sauce

For the Creamy Sauce:

2 tablespoons unsalted butter
2 tablespoons all-purpose flour
1 ½ cups milk (whole or 2%)
1 teaspoon garlic powder
½ teaspoon salt
¼ teaspoon black pepper

Step-by-Step Instructions

1. Preheat Oven:

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.

2. Prepare the Creamy Sauce:

In a skillet, melt butter over medium heat. Whisk in flour and cook for 1-2 minutes until lightly golden. Slowly whisk in milk, stirring constantly until the mixture thickens. Add garlic powder, salt, and pepper. Remove from heat and set aside.

3. Sauté the Mushrooms and Spinach:

In the same skillet, sauté the mushrooms over medium heat for 3-4 minutes until softened. Add the spinach and cook for an additional 1-2 minutes until wilted.

4. Assemble the Casserole:

Spread a thin layer of marinara sauce on the bottom of the baking dish. Layer half of the ravioli over the sauce. Top with half of the mushrooms and spinach, then sprinkle with half of the mozzarella. Pour half of the creamy sauce over this layer. Repeat the layers with the remaining ravioli, mushrooms, spinach, mozzarella, and creamy sauce. Finish by spreading the remaining marinara sauce over the top and sprinkling with Parmesan cheese.

5. Bake the Casserole:

Cover the dish with foil and bake for 20 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden.

6. Serve and Enjoy:

Let the casserole cool for 5 minutes before serving. Garnish with fresh parsley or basil if desired.

Recipe Tips

Add Protein: For a heartier dish, add cooked Italian sausage or shredded chicken to the layers.
Switch the Sauce: Use Alfredo sauce instead of marinara for an even creamier dish.
Use Fresh Ravioli: Fresh ravioli cooks faster and adds a more delicate texture to the dish.

What to Serve with Cheesy Mushroom Ravioli Casserole

Garlic Bread: Perfect for soaking up the creamy sauce.
Side Salad: A crisp green salad with a light vinaigrette complements the richness of the casserole.
Steamed Vegetables: Serve with roasted broccoli or asparagus for added veggies.
