Ingredients

• 2 large boneless skinless chicken breasts
• 12 oz penne pasta
• 2 cups low-sodium chicken broth
• 1 can (10.5 oz) cream of chicken soup
• 8 oz cream cheese, softened and cubed
• 1 cup shredded mozzarella cheese
• 1 cup shredded sharp cheddar cheese
• ½ cup freshly grated Parmesan cheese
• 1 tablespoon olive oil
• 3 garlic cloves, minced
• 1 small yellow onion, finely diced
• 1 teaspoon Italian seasoning
• 1 teaspoon paprika
• ½ teaspoon onion powder
• ½ teaspoon black pepper
• ½ teaspoon salt, or to taste
• 2 tablespoons chopped fresh parsley

Instructions

Prepare the Slow Cooker

Lightly grease the inside of your slow cooker with olive oil or nonstick cooking spray. This helps prevent the creamy sauce from sticking and makes cleanup much easier once the casserole is finished.

Season the Chicken

Pat the chicken breasts dry with paper towels before placing them into the slow cooker. Sprinkle both sides with the Italian seasoning, paprika, onion powder, salt, and black pepper so every bite is packed with savory flavor.

Build the Creamy Base

Add the diced onion and minced garlic around the chicken, then pour in the chicken broth and cream of chicken soup. Stir gently until the soup blends with the broth, then scatter the cubed cream cheese over the top. As the casserole cooks, the cream cheese will slowly melt into the sauce, creating a rich and creamy texture.

Slow Cook Until Tender

Cover the slow cooker with the lid and cook until the chicken becomes tender enough to shred easily with two forks. Once fully cooked, remove the chicken to a cutting board, shred it into bite-sized pieces, and return it to the creamy sauce. Stir everything together until the chicken is evenly coated and the sauce becomes smooth and velvety.

Cook the Pasta

About 20–25 mins before serving, cook the penne pasta in a large pot of salted water until just al dente according to the package directions. Drain the pasta well, but do not overcook it since it will continue to absorb some of the creamy sauce after being mixed into the slow cooker.

Add the Cheese

Stir the shredded mozzarella cheese, shredded cheddar cheese, and freshly grated Parmesan cheese into the creamy chicken mixture. Continue stirring until the cheeses melt completely, creating a thick, smooth, and irresistibly cheesy sauce.

Combine Everything

Add the cooked penne pasta to the slow cooker and gently fold it into the creamy chicken mixture until every piece of pasta is evenly coated with the rich cheese sauce. Cover the slow cooker and cook for another 10–15 mins so the pasta absorbs the flavors and the casserole becomes perfectly creamy.

Finish and Serve

Turn off the slow cooker and sprinkle the chopped fresh parsley over the casserole just before serving. Allow it to rest for 5 mins to thicken slightly, then scoop generous portions onto serving plates while the cheese is still hot and melty.

Tips

• Cook the pasta only until al dente to keep it from becoming too soft after mixing with the sauce.
• Freshly grate the mozzarella, cheddar, and Parmesan for the smoothest, creamiest texture.
• Stir the casserole gently when adding the pasta to keep the chicken tender and prevent the noodles from breaking.

Variations

For extra vegetables, stir in steamed broccoli, baby spinach, peas, or sautéed mushrooms during the final few mins of cooking. If you enjoy a little heat, add crushed red pepper flakes or a pinch of Cajun seasoning to the creamy sauce. For even more cheesy flavor, substitute Monterey Jack or Colby Jack cheese for part of the cheddar, or top each serving with extra Parmesan before serving.

What to Serve With

This Slow Cooker Creamy Chicken Pasta Casserole pairs wonderfully with garlic bread, warm dinner rolls, Caesar salad, roasted broccoli, garlic green beans, roasted asparagus, or a crisp garden salad with a light vinaigrette. These simple side dishes balance the richness of the creamy casserole while creating a complete family meal.

Storage & Reheating

Allow the casserole to cool completely before transferring leftovers to an airtight container. Store in the refrigerator for up to 4 days.

For longer storage, divide the casserole into individual freezer-safe containers and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

To reheat, warm individual portions in the microwave, stirring every 30 seconds until heated through. For larger portions, reheat gently in a saucepan over low heat with a splash of chicken broth or milk to restore the creamy consistency without drying out the sauce.
