Recipe summary
- Yield: 4 servings
- Prep time: 10 minutes
- Cook time: 3 hours on high (or about 5 hours on low)
- Total time: ~3 hours 10 minutes (when using high heat)
Ingredients
(Printable recipe card can be created from this list.)
- 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 and pepper, to taste
- 1 pound penne pasta (about 4 cups dried)
Step-by-step instructions
- Heat 1 tablespoon olive oil and 2 teaspoons butter in a heavy skillet over medium-high heat (a cast iron skillet works well). Once hot, add the chicken breasts so they sizzle on contact. Season with salt, pepper, and the Italian seasoning. Sear 2–3 minutes per side until each side is golden brown; the chicken will finish cooking in the crock pot.
- Transfer the seared chicken breasts to the bottom of the slow cooker.
- Add the crushed garlic to the crock pot and pour the heavy cream over the chicken. If desired, pour a little of the cream into the skillet and scrape up any browned bits, then add that to the crock pot for extra flavor.
- Season again with salt and pepper, then cover and cook on high for 3 hours or low for about 5 hours. Cooking times can vary by slow cooker, so check for a bubbly sauce and fully cooked chicken (internal temperature 165°F / 74°C).
- When done, remove the chicken to a cutting board and slice or shred into bite-sized pieces. Return the chicken to the sauce and stir to combine.
- Cook the penne pasta according to package directions just before serving. Drain well.
- Either ladle the chicken Alfredo sauce over the cooked penne or stir the pasta into the sauce in the slow cooker for a fully combined dish. Finish with grated Parmesan and a sprinkle of chopped fresh parsley if desired.
Tips for best results
- Sear the chicken before slow cooking: this builds flavor and helps keep the meat juicy.
- After searing, pour a small amount of cream into the hot pan and scrape up the browned bits, then add that to the slow cooker to intensify the sauce.
- For a spicier version, season the chicken with Cajun spice or red pepper flakes before searing.
- If your sauce thickens too much, stir in a splash of milk or reserved pasta cooking water to reach your desired consistency.

Storage
Refrigerate leftovers in an airtight container for up to 3 days. For longer storage, place cooled portions in airtight containers or freezer bags and freeze for 3–6 months. Thaw frozen portions in the refrigerator before reheating.
How to reheat leftovers
