Chicken Alfredo Sauce

You can use homemade sauce or pre-made sauce jars. I used two jars of sauce for this recipe in order to save time and for just for convenience. Homemade alfredo is relatively simple to make. It’s a combination of a roux with flour, butter, heavy cream, parmesan, garlic and Italian seasoning.

What Sides to Serve with Homemade Chicken Fettuccine Alfredo?

Bread is my favorite side. Try garlic bread or cheesy bread sticks. You can even serve it along with pizza.

Salad is a great choice because it’s light and balances the heavy pasta.

This pasta also goes well with most vegetables pairings such as Slow Cooker Glazed Carrots or Slow Cooker Green Bean Casserole, roasted vegetables, or even a raw veggie tray.

It also pairs well with soups such as a simple tomato soup or roasted red pepper soup.

What is the Difference Between Chicken Alfredo and Chicken Fettuccine?

Alfredo refers to a creamy white sauce, and fettuccine refers to the type of thick flat pasta noodle typically served with either alfredo sauce or a tomato based red sauce.

Variations for Chicken Alfredo Pasta

Penne alfredo– Use Penne pasta in place of fettucine noodles.

Chicken broccoli alfredo– Mix in freshly cut broccoli florets in the final 20 minutes of cooking.

Use cajun chicken alfredo– Add cajun seasoning instead of Italian seasoning.

Use blackened chicken– Blacken the chicken on the grill before adding for additional flavor.

Chicken tortellini alfredo– Use tortellini in place of fettuccine noodles.

Add other proteins– Such as shrimp, beef, tofu, smoked sausage, or even vegan meat.

Use stuffed shells or ravioli– In place of the fettuccine noodles.

Use leftover grilled chicken– This saves time and is a great way to use up leftovers. Mix it in towards the end of cooking to warm the chicken before serving.

Add vegetables– Such as peas, artichokes, spinach, kale, tomatoes, roasted red peppers, or cauliflower.

Make it spicy– Add red chili flakes for a spicier version.

Add bacon– Sprinkle crumbled bacon on top, prior to serving for added flavor and texture.

Add other kinds of cheese- Such as goat cheese, cream cheese, ricotta, mozzarella, cheddar. The possibilities are endless!

Add pesto– This will add a strong herby basil flavor. It will also add a subtle green color to the pasta.

Tips And Techniques

What size crockpot should I use? I recommend using a 6 quart crock pot or larger.

How long do I cook the pasta? Cook for 2.5 hours with the crockpot on low heat.

Do I need to cook the chicken before putting it in the crockpot? You do not need to cook the chicken before adding it to the crockpot, it will have plenty of time to cook. However, make sure the chicken is thawed before adding it or else the meal will become too watery.

Adjust seasoning– Add more or less according to your preference.

How to thicken pasta? If, for some reason, your pasta ends up too thin, simply cook it uncovered a little longer until some of the liquid has steamed off. You can also discard some of the excess liquid. Pasta will also also absorb a lot of the sauce over time.

How to make pasta thinner? If your pasta is too thick or you just prefer it thinner, simply add a bit of of broth or water or even milk to achieve the desired consistency.

What kind of cheese to use? Use freshly shredded parmesan cheese. The quality and flavor is so much better than the packets.


Refrigerate– In a sealed container for up to 2 days.

Freeze– This is not recommended since pasta and dairy does not thaw well.

Reheat– In the microwave or stovetop. You can add a splash of water if it’s too thick.
