- 12 ounces fettuccine (to be added later): Classic pasta choice that captures the sauce in every bite.

How to Make Slow Cooker Chicken Alfredo Recipe
Step 1: Combine Chicken and Sauce Ingredients
Start by placing the chicken breasts in the bottom of your slow cooker – this ensures they cook evenly and soak up all the sauce flavors. Pour in the heavy cream, chicken broth, and minced garlic, then sprinkle the Italian seasoning, salt, and black pepper over the top. This simple mix creates an irresistible base that will gently transform into a creamy Alfredo sauce as it cooks.
Step 2: Slow Cook the Chicken
Set the slow cooker to low and let everything simmer away for 4 to 5 hours. This slow, low heat makes the chicken incredibly tender, allowing it to absorb those rich flavors while the sauce thickens naturally. The aroma that fills your kitchen at this stage is truly irresistible and builds anticipation for the final dish.
Step 3: Shred the Chicken
Once the chicken is fork-tender and fully cooked, carefully remove it from the slow cooker and shred it with two forks. This step transforms the chicken into bite-sized pieces that will beautifully blend throughout the creamy sauce, ensuring every forkful is loaded with protein and flavor.
Step 4: Add and Cook the Pasta
Break the fettuccine noodles in half and stir them into the slow cooker, making sure they’re mostly submerged in the sauce. Cover and switch to high heat, cooking for 25 to 35 minutes. Give it a stir one or two times during this period to prevent sticking. The pasta will soak up all those decadent flavors and reach perfect tenderness right in the slow cooker.
Step 5: Finish with Parmesan and Butter
Once the pasta is tender, stir in the freshly grated Parmesan cheese and butter until everything melts together into a smooth, creamy sauce. If the sauce seems too thick, add a splash of warm milk or chicken broth to loosen it up. This finishing touch ensures your Slow Cooker Chicken Alfredo Recipe boasts that classic creamy texture that’s irresistibly satisfying.

Garnishes

Make Ahead and Storage
Storing Leftovers
Store any leftovers in an airtight container in the refrigerator for up to 3 days. The pasta will absorb more sauce as it sits, so you may want to loosen it with a splash of milk when reheating.
Freezing
Although cream-based sauces can sometimes separate when frozen, you can freeze this dish if needed. Portion it into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating gently.
Reheating
Reheat leftovers slowly on the stove over low heat, stirring frequently to restore the creamy texture. Add a bit of milk or chicken broth as needed to bring the sauce back to lusciousness without drying out the pasta.
FAQs
Can I use chicken thighs instead of chicken breasts?
Absolutely! Chicken thighs will add a bit more richness and stay moist during slow cooking, making them a great substitute in this recipe.
Is it possible to make this gluten-free?
Yes, simply swap out the fettuccine for your favorite gluten-free pasta to keep the dish safe for gluten-sensitive diners without sacrificing flavor or texture.
Can I add vegetables to this recipe?
Definitely! Stir in some steamed broccoli or spinach towards the end of cooking for an easy way to add color, nutrients, and extra flavor.
What if I don’t have freshly grated Parmesan cheese?
Freshly grated Parmesan melts better and provides richer flavor, but in a pinch, you can use pre-grated. Just expect a slightly different texture and flavor intensity.
Can I make this recipe on high instead of low?
While it’s best to let the chicken cook slowly on low for tender, juicy results, you can cook on high for about 2 to 3 hours if you’re short on time, just keep an eye to avoid overcooking.
