Slow Cooker Cajun Chicken Alfredo with Sausage- this family favorite cooks up effortlessly in the slow cooker with so much flavor. It's wonderfully creamy with plenty of Cajun spice to jazz it up.
Heat oil over medium-high heat in a medium skillet. Season chicken lightly with salt and pepper and add it to the pan. Cook until golden brown on both sides.Transfer to a 6-quart crock pot.
Add the sausage, heavy cream, 2 cups of chicken broth, Cajun seasoning, garlic powder, onion powder, Italian seasoning, crushed red pepper flakes and butter to slow cooker.Cover and cook on LOW for 4 1/2 to 5 hours.
Heat the remaining cup of chicken broth until hot. Add it to the slow cooker.Stir in penne and 1/2 cup of Parmesan cheese.Cover and cook on LOW for 30 minutes or until pasta is cooked.
Stir in remaining 1/2 cup of Parmesan cheese.Remove the chicken to a cutting board. Let cool slightly and then slice it. Add back to slow cooker.
If you want to thicken the sauce, first remove all the noodles, chicken and sausage with a slotted spoon and place them in a large bowl.Stir together cornstarch with 1 tablespoon of cold water. Add to sauce. Turn slow cooker to HIGH and cook until it begins to simmer.To do this step faster, you can transfer the sauce to a pot and place over high heat until it boils.Note: The sauce will also thicken some as it cools and the pasta absorbs some of the liquid.
Notes
Check for seasoning at the end. The cajun seasoning, chicken broth, and Parmesan all add quite a bit of salt so it is unlikely it will need more.
