Ingredients

For the Chicken & Sauce

1 lb boneless, skinless chicken breasts about 2 medium pieces
2 cups heavy cream
1 cup low-sodium chicken broth
4 Tbsp butter, softened
1/2 tsp garlic powder or use 2 cloves fresh minced garlic for stronger flavor
1/2 tsp Italian seasoning
Kosher salt, to taste
Freshly ground black pepper, to taste

For the Pasta & Finish

1/2 lb rigatoni (or any short pasta) penne, rotini, or ziti work well
1/3 cup freshly grated Parmesan cheese avoid pre-shredded for best texture
Fresh parsley, finely chopped — for garnish optional

Method

Step 1 — Build the Sauce Base: Add chicken breasts, heavy cream, butter, and chicken broth to your slow cooker. Season with garlic powder, Italian seasoning, salt, and pepper. Stir to combine. This infuses the chicken with rich flavor as it cooks.
Step 2 — Slow Cook & Shred: Cover and cook on HIGH for 2 hours, or until chicken is cooked through and tender. Remove the chicken and shred it with two forks, then set aside. If the chicken doesn’t shred easily, cook for another 15–20 minutes.
Step 3 — Cook the Pasta: Stir the rigatoni and Parmesan into the slow cooker. Cover and cook for 20–25 minutes, stirring once halfway through. Pasta should be al dente — tender but still slightly firm.
Step 4 — Combine & Serve: Return shredded chicken to the slow cooker and stir until everything is creamy and evenly coated. Sprinkle with fresh parsley and extra Parmesan before serving.

Notes

Tips: For a lighter version, replace half the cream with milk and whisk in 1 tsp cornstarch. Swap chicken breasts for thighs for extra tenderness. Stir pasta once while cooking to prevent clumping. Add frozen peas, spinach, or steamed broccoli at the end for a veggie boost.
