Ingredients for Easy Crock Pot Chicken Alfredo

(Printable recipe card: see the recipe section below.)

• 3 boneless, skinless chicken breasts (about 1 pound)
• 1 tablespoon olive oil
• 2 teaspoons butter
• 1 teaspoon Italian seasoning
• 2 cups heavy cream
• 4 cloves fresh garlic, crushed
• Salt & pepper to taste
• 1 pound penne pasta (about 4 cups dried)

Step-by-Step Instructions: Crock Pot Chicken Alfredo

1. Heat 1 tablespoon olive oil and 2 teaspoons butter in a heavy skillet over medium-high heat. Add the chicken breasts; they should sizzle. Season with salt, pepper, and 1 teaspoon Italian seasoning. Sear each side until golden brown, about 2–3 minutes per side. The chicken will not be fully cooked through—this is just to develop flavor.
2. Transfer the seared chicken breasts to the bottom of the crock pot.
3. Add the crushed garlic and pour the heavy cream over the chicken. Season with additional salt and pepper to taste.
4. Cook on high for about 3 hours or on low for about 5 hours. Slow cooker times vary, so check that the sauce is bubbling and the chicken is cooked through.
5. When the chicken is cooked and the sauce is hot, remove the chicken and place on a cutting board. Slice into bite-sized pieces and return them to the sauce, stirring to combine.
6. Cook the penne pasta according to package directions just before serving, then drain.
7. Ladle the chicken Alfredo sauce over the cooked penne or stir the sauce and pasta together in the crock pot before serving. Finish with freshly grated Parmesan and a sprinkle of chopped parsley if desired.

Tips to Make the Best Crock Pot Chicken Alfredo

• Searing the chicken first builds a golden crust and deepens the flavor of the finished dish.
• For extra depth, pour a little of the heavy cream into the skillet after searing and scrape up the brown bits, then add that cream to the crock pot.
• If you like heat, season the chicken with a bit of Cajun seasoning before searing for a spicier version.

Storage: How to Keep Leftovers

Store leftovers in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze the leftovers in an airtight container or zip-top bag for 3–6 months. Note that cream-based sauces can change texture after freezing; gently reheat and stir to restore creaminess.

How to Reheat Chicken Alfredo & Pasta

1. Oven method: Place thawed chicken Alfredo and pasta in an oven-safe dish. Add a few tablespoons of water or cream, cover tightly with foil, and bake at 375°F (190°C) for about 10 minutes. Stir, re-cover, and bake another 10 minutes or until heated through.
2. Microwave method: Place leftovers in a microwave-safe bowl, cover loosely, and heat in 1-minute intervals, stirring between each interval until hot.
