How to Make Chicken Alfredo Tortellini Casserole

Step 1: Prep the Oven

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

Step 2: Mix the Filling

In a large mixing bowl, stir together:

• Cooked tortellini

• Shredded chicken

• Alfredo sauce

• Sour cream

• Half the mozzarella and parmesan

• Garlic powder, salt, pepper

• Fresh parsley

Mix until everything is evenly coated in the rich, creamy sauce.

Step 3: Layer It Up

Transfer the mixture into your prepared baking dish, spreading it into an even layer.

Step 4: Add Toppings

Sprinkle the remaining mozzarella and parmesan evenly over the casserole.
In a small bowl, combine panko breadcrumbs with melted butter and scatter over the cheese layer.

Step 5: Bake to Perfection

Bake uncovered for 25–30 minutes, until:

• The cheese is melted and bubbling

• The breadcrumb topping is golden brown

Step 6: Rest and Garnish

Let the casserole sit for 5 minutes to set.
Garnish with extra chopped parsley before serving for a pop of freshness.

Serving Suggestions

Pair this creamy baked tortellini with:

• Garlic bread or buttery breadsticks

• A fresh Caesar salad or simple green salad

• Roasted vegetables like broccoli or asparagus

• A crisp glass of Chardonnay or sparkling water with lemon

Tips for Success

• Use rotisserie chicken to save time.

• Don’t overcook the tortellini—they’ll finish cooking in the oven.

• Add baby spinach or steamed broccoli for extra nutrition.

• Prefer a spicy twist? Stir in crushed red pepper flakes or a pinch of cayenne.
