Ingredients for Slow Cooker Chicken Fettuccine Alfredo

Black pepper: Adds mild heat and depth.
Chicken broth: Thins the sauce just enough and adds savory flavor.
Heavy cream: Creates a rich, classic alfredo base.
Cream cheese: Helps the sauce stay creamy and smooth while cooking.
Butter: Adds richness and rounds out the sauce.
Fresh garlic cloves: Brings that signature alfredo flavor.
Dry fettuccine pasta: Cooks directly in the sauce and absorbs flavor.
Shredded parmesan cheese: Thickens the sauce and adds salty, nutty flavor.
Fresh parsley: Brightens the finished dish and adds color.
How to Make Slow Cooker Chicken Fettuccine Alfredo
- Place chicken breasts in an even layer in the crockpot and season with salt and pepper. You can leave them whole or cut them into chunks.
- Add the chicken broth, heavy cream, cream cheese, butter, and minced garlic.
- Cover and cook on low for 4 hours or high for 2 hours, until the chicken is fully cooked and tender.
- If you started with whole chicken breasts, remove them, chop or shred, then put back into the crockpot.
- Add the uncooked fettuccine pasta and shredded parmesan cheese. Stir gently to combine with the sauce.
- Cover and continue cooking on high for 30 minutes or on low for 1 hour, until the pasta is tender.
- Sprinkle with fresh parsley before serving.
When to Add Pasta to the Slow Cooker
This deserves special attention because it matters.
Pasta should only be added after the chicken has finished cooking. The hot, creamy sauce will cook the noodles quickly and evenly. If the sauce thickens too much while the pasta cooks, simply stir in a splash of chicken broth.
Quick Fix Guide
Sauce too thick? Add more broth.
Sauce too thin? Stir in extra parmesan cheese and let it rest for a few minutes.
