Ingredients

Main Ingredients

  • 1 (25 oz) package frozen ravioli (cheese or your favorite)

  • 1 pound Italian sausage (sweet or mild), browned and drained

  • 1 medium onion, diced

  • 1 teaspoon garlic powder

  • 2 tablespoons butter

  • 2 tablespoons all-purpose flour

  • 2 cups milk (whole or 2%)

  • 1 cup sour cream

  • 1½ cups shredded mozzarella cheese

  • 1½ cups shredded cheddar cheese

  • ½ cup grated Parmesan cheese

  • Salt and pepper, to taste

  • Optional: chopped fresh parsley or basil for garnish

Instructions

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter.

Step 2: Cook the Sausage

In a large skillet over medium heat, cook the Italian sausage until fully browned. Drain excess grease and add diced onion. Sauté until the onion is softened, about 3–4 minutes.

Stir in garlic powder, then remove the pan from heat.

Step 3: Make the Creamy Cheese Sauce

In a medium saucepan, melt the butter over medium heat. Sprinkle in the flour and whisk until smooth. Slowly pour in the milk while whisking constantly to avoid lumps.

Continue cooking and whisking until the sauce thickens, about 3–5 minutes. Remove from heat and stir in the sour cream until smooth. Season with salt and pepper.

Step 4: Combine Layers

In the prepared baking dish, spread the frozen ravioli in an even layer. Top with the cooked sausage and onion mixture.

Pour the creamy cheese sauce evenly over the ravioli and sausage. Sprinkle the mozzarella, cheddar, and Parmesan evenly on top.

Step 5: Bake

Bake uncovered for 30–35 minutes, or until the casserole is bubbly and the cheese is melted and lightly golden.

Step 6: Rest and Serve

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

Tips & Variations

  • Vegetable Boost: Add sautéed spinach, mushrooms, or bell peppers to the sausage mixture.

  • Spicy Twist: Use hot Italian sausage or add red pepper flakes.

  • Four-Cheese Version: Mix in fontina or provolone with the mozzarella.

  • Comfort Upgrade: Stir in a cup of ricotta into the sauce for extra creaminess.

  • Make-Ahead: Assemble the casserole a day ahead and refrigerate before baking.

Serving Suggestions

This casserole is a meal on its own, but pairs wonderfully with:

  • Garlic bread or cheesy breadsticks

  • Fresh green salad with a tangy vinaigrette

  • Steamed or roasted vegetables

  • A glass of red wine or iced tea

Storage

  • Refrigerator: Store leftovers in an airtight container for up to 4 days.

  • Freezer: Freeze baked casserole for up to 2 months. Thaw overnight in the fridge before reheating.
