Why this crock pot chicken alfredo recipe works

Cooking a recipe like this from scratch can be a little tricky, which is why having this crockpot chicken alfredo recipe on hand is a must. It takes the guesswork out of choosing the right ingredients to get the best taste and instead helps you put dinner on the table effortlessly. If you want a spicy version, try my Slow Cooker Cajun Chicken Alfredo Recipe.

I especially enjoy the quick prep time and cooking time. Once the alfredo sauce ingredients are mixed together, all there is left to do is pour it over the chicken breasts and slow cook. Toward the end of the cooking time, you’ll cook the pasta separately until al dente, and that’s it! If you love chicken alfredo, this is truly a chicken alfredo crockpot recipe to add to your next meal plan!

Recipe Ingredients

Ingredinets for chicken alfredo on a table.

Chicken: I prefer to use boneless skinless chicken breasts; however you can also use chicken tenders or boneless skinless chicken thighs. Do not use frozen chicken.
Homemade Alfredo Sauce: Heavy Cream, grated parmesan cheese (not shredded parmesan cheese), minced fresh garlic, dried Italian seasoning, kosher salt, and black pepper.
Pasta: This recipe can be made with any pasta of your choice, as fettuccine noodles are the normal choice. Though, I love how it turns out with penne pasta. The uncooked pasta is boiled on the stovetop, not added to the slow cooker dry. We also use penne pasta in my cheesy chicken penne recipe.
Garnish: Fresh parsley tastes delicious on top of this finished pasta dish.

Step Five – Cover the slow cooker and cook on LOW for 6-8 hours until the chicken is cooked through and tender. (I don’t recommend cooking this recipe on high as the cheese will burn in the sauce).

Step Six – Remove the chicken breasts from the slow cooker and shred them using two forks. Return the shredded chicken to the slow cooker.

Step Seven – Stir the chicken into the alfredo sauce. Add in the cooked penne pasta.

Step Eight – Stir the pasta together with the pasta sauce. Serve the slow cooker chicken alfredo and garnish with fresh chopped parsley. Enjoy!

How to serve

You can’t go wrong by serving this as-is on a small plate or bowl.
It also tastes great topped with chopped bacon, chopped green onion, a dash of red pepper, freshly cracked black pepper, extra parmesan cheese, or any topping of your choice.
Consider serving the best crockpot chicken alfredo alongside a small green salad and slices of Italian bread or breadsticks. Fresh steamed broccoli or slow cooker brussels sprouts are always a great choice too.

Recipe FAQs

What are some ways I can customize this creamy dish?

You can customize this recipe by adding your favorite vegetables or other additions such as cooked bacon, add broccoli florets, sauteed mushrooms, spinach, or sun-dried tomatoes. You can also add cubed butter.

What do I do if the sauce is too thick?

If the alfredo sauce is too thick, you can thin it out by adding a little chicken broth, chicken stock, or pasta water.

Is there a way to adjust the seasoning?

Adjust the seasoning according to your taste preferences. Feel free to add more salt, pepper, or Italian seasoning as desired. You can also add onion powder, garlic powder, or a little spice.

Why shouldn’t I cook this on high heat?

This recipe is specifically designed for cooking on low heat in the slow cooker. Cooking on high heat may cause the cheese to burn. Crockpot meals like this do not need high heat.

How do I store leftover chicken alfredo?

Leftover slow cooker chicken alfredo can be stored in an airtight container in the refrigerator for up to 3-4 days. I don’t recommend freezing chicken alfredo because of the milk content.

How do I reheat this crock pot chicken alfredo recipe?

To reheat, you can use the microwave or heat it gently on the stovetop, adding a splash of cream to restore the creamy consistency.

Can I use jarred alfredo sauce?

Sure! It will not taste the same. Jarred alfredo has a distinct taste that is not the same as homemade.
