How do you crank out a creamy chicken Alfredo with minimal effort? You make it in a crock pot! This delicious, easy to make, slow cooker chicken Alfredo is a family favorite for dinner! And this crock pot chicken Alfredo is perfect for serving a crowd, or for storing in the freezer and reheating later!
I’m not going to lie, I am sucker for a good Alfredo sauce and have been since I was a kid. It’s like mac and cheese on steroids but not terribly healthy. This recipe isn’t really either, but it has a lot of added protein with the chicken so I can have some as a treat and my family devours it.
I can’t believe it has taken me this long to come up with an easy slow cooker chicken Alfredo. Probably because I think pasta cooked in a crock pot gets mushy. But I remedy this by cooking the chicken and sauce and adding the pasta the last 20 minutes before serving. Problem solved.

How to Make Chicken Alfredo in A Slow Cooker
- Fresh parmesan must be used in this recipe to keep a smooth consistency in the sauce.
- For a thicker, creamier sauce, use a strainer to pour only the sauce into a large saucepan. Add two tablespoons of cornstarch and ¼ cup of warm water to a small bowl and mix to combine. Add the cornstarch mixture to the saucepan and bring the liquid to a low boil. Turn the heat down and allow the sauce to simmer, stirring consistently until thickened. Turn off the heat and pour the sauce back into the crock pot. Stir to combine.

I am not a white sauce fan, but hubby is. So this would be an easy way to please his palate without my having to deal too much with the alfredo part!
We are Gluten-free but also dairy -free!! Could I use coconut milk here with the cornstarch to make this dairy-free?!
