Chicken Spaghetti Casserole

Instructions

Step 1 – Cook the Spaghetti

Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package instructions until al dente. Drain well and set aside.

Step 2 – Prepare the Chicken Mixture

In a large skillet, heat butter or olive oil over medium heat. Add the chopped onion and garlic, and sauté until fragrant and translucent, about 2–3 minutes.

Add the shredded chicken to the skillet and stir until warmed through.

Step 3 – Make the Creamy Sauce

In a large mixing bowl, combine the cream of mushroom soup, cream of chicken soup, and sour cream. Mix until smooth.

Add the cooked chicken and onion mixture, along with black pepper and paprika if using. Stir to combine.

Step 4 – Assemble the Casserole

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

Add the cooked spaghetti to the chicken mixture and stir until the pasta is evenly coated with the creamy sauce. Transfer everything to the prepared baking dish.

Sprinkle the cheddar and mozzarella cheese evenly over the top. For extra flavor, sprinkle with grated Parmesan if desired.

Step 5 – Bake

Bake in the preheated oven for 25–30 minutes, or until the cheese is melted, bubbly, and slightly golden on top.

Step 6 – Serve

Remove from the oven and let it rest for 5 minutes before serving. Garnish with fresh parsley for a pop of color and freshness.

Serve this Chicken Spaghetti Casserole with a simple side salad or garlic bread for a complete meal.
