Ingredients for the Best Slow Cooker Chicken Alfredo

Parmesan Cheese: Provides a salty, nutty kick that defines Alfredo.
Chicken Broth: Adds moisture and savory flavor to the base.

How To Make the Best Slow Cooker Chicken Alfredo

Step 1: Layer and Cook the Chicken

Place the chicken breasts in the bottom of your slow cooker. Pour in the chicken broth, and season with garlic powder, onion powder, salt, and pepper. Cover and cook on low for 4-5 hours or until the chicken is tender.

Step 2: Shred the Chicken

Once the chicken is cooked through and falling apart, remove it and shred it using two forks. Return the shredded chicken to the slow cooker.

Step 3: Add Creamy Elements

Stir in the heavy cream, cream cheese, and grated Parmesan. Whisk well until smooth and creamy. Let it cook for another 15-20 minutes on low, stirring occasionally.

Step 4: Cook the Pasta Separately

While the sauce thickens, boil the penne pasta in a separate pot according to package instructions until al dente. Drain and add it into the slow cooker, gently mixing to coat the pasta evenly.

Step 5: Garnish and Serve

Top with a sprinkle of freshly chopped parsley and cracked black pepper. Serve warm and creamy right from the slow cooker!

Serving and Storing This Chicken Alfredo

This dish is best enjoyed hot right out of the slow cooker, served with garlic bread or a fresh green salad. For leftovers, store in an airtight container in the refrigerator for up to 4 days. The sauce may thicken as it chills, so add a splash of milk or broth when reheating to revive its creamy texture.

This Alfredo also freezes well. Just place portions in freezer-safe containers and thaw overnight before reheating gently on the stove.

Frequently Asked Questions

Can I use rotisserie chicken instead?

Absolutely! Using pre-cooked chicken can reduce the slow cooker time. Just stir it in with the cream and cheese mixture.

Can I substitute the heavy cream?

Yes, you can use half-and-half or whole milk, but the sauce may be slightly less rich and thick.

Is it okay to add vegetables?

Definitely! Broccoli, spinach, or mushrooms make great additions. Add them during the last hour of slow cooking.

Can I use a different pasta?

Penne works best for holding the creamy sauce, but fettuccine, rotini, or rigatoni are great alternatives.

How do I make it gluten-free?

Swap the pasta with a gluten-free variety and ensure all other ingredients are certified gluten-free.

What if my sauce is too thick?

Stir in a little warm milk or broth until you reach your desired consistency.
