Step-by-Step Instructions: How to Make Cheesy Chicken Pasta Casserole
This casserole comes together in just a few simple steps. Follow along and get ready to indulge!
Step 1: Cook the Pasta
- Bring a large pot of salted water to a boil.
- Cook 2 cups of pasta according to the package instructions until al dente (don’t overcook, as it will bake further in the oven).
- Drain and set aside.
Step 2: Prepare the Chicken
- If using leftover or rotisserie chicken, shred it into bite-sized pieces.
- If cooking fresh chicken, season with salt, pepper, and Italian seasoning, then bake at 375°F (190°C) for 20-25 minutes until fully cooked. Shred or chop into cubes.
Step 3: Make the Creamy Sauce
- In a large mixing bowl, whisk together:
- Cream of chicken soup
- Sour cream
- Milk
- Garlic powder, onion powder, salt, pepper, and Italian seasoning
- Stir in 2 cups of shredded cheese until melted and creamy.
Step 4: Combine Everything
- Add the cooked pasta and shredded chicken into the creamy sauce mixture.
- Stir until everything is well-coated.
Step 5: Assemble the Casserole
- Preheat oven to 375°F (190°C).
- Grease a 9×13-inch baking dish with butter or non-stick spray.
- Pour the pasta-chicken mixture into the dish and spread it evenly.
Step 6: Add the Cheesy Topping
- Sprinkle 1 cup of shredded cheese evenly over the casserole.
- In a small bowl, mix breadcrumbs (or crushed crackers) with melted butter, then sprinkle over the cheese.
- This will create a crispy, golden crust on top!
Step 7: Bake to Perfection
- Place the casserole in the oven and bake for 25-30 minutes, or until the cheese is bubbly and golden brown.
- If you love an extra crispy top, turn on the broiler for the last 2-3 minutes (just watch closely so it doesn’t burn!).
Step 8: Garnish and Serve
- Remove from the oven and let it sit for 5 minutes to set.
- Sprinkle with fresh parsley for color and freshness.
- Serve hot and enjoy!
