How to make chicken Alfredo in the Instant Pot
Traditional fettuccine Alfredo is heavy on the butter, and so is this Instant Pot Alfredo.
You really need it to make the sauce rich and creamy. So even though you may be tempted to use jar sauce or cream cheese, you really don't need it!
Just cut up chicken breasts, and cook it for about 5 minutes on the Saute setting -- just until it's no longer pink.
As you're cooking the chicken pieces, add your seasonings. Make sure to deglaze the bottom of the pot with a little chicken broth so there are no chicken bits sticking to the pot.
Turn off the saute setting. Then, layer the pasta over the chicken.
Add the chicken broth or water. Then, add the pats of butter over the pasta. Don't stir everything together, or the pasta won't cook.
Pressure cook the pasta for 4 minutes on high pressure, then do a gradual quick release.
This pasta recipe tends to spurt out all over the place if you do a quick pressure release. So unless you don't mind a huge mess, stick with a controlled pressure release!
On a side note, I only seem to have a problem with pasta water making a mess when I use my 6-quart Instant Pot. When I use the 8 quart electric pressure cooker, it's fine.
Next, add some heavy cream, more butter, Parm and a little bit of nutmeg. The sauce looks thin at first, but it firms up in no time as it cools down.
You can even go back to Saute mode and reduce the sauce for a couple of minutes if you want.
Personally, I like to add heavy cream in the Instant Pot at the end, after pressure cooking. I just think it works better this way.
The sauce thickens as it rests, and by the time you eat it, you get an incredibly rich and creamy Instant Pot chicken Alfredo pasta.
Variations and Substitutions
For this Instant Pot chicken Alfredo recipe I usually like to use penne pasta, as it holds the thick sauce well. Rotini is another good choice!
Of course, fettuccine noodles are a popular pasta to eat with Alfredo sauce, so you could use those instead for an Instant Pot fettuccine Alfredo. Just make sure to break noodles up before cooking.
Homemade Alfredo sauce works great, but you can use store-bought jarred sauce too, if you prefer. I recommend adding the sauce after pressure cooking.
Instead of cutting whole breasts into chicken pieces, use chicken tenders. Add broccoli florets for a one pot meal with veggies!
The best part of this recipe--besides how easy it is!--is making each serving into your own perfect comfort food dish! Sprinkle the top of the pasta with fresh herbs, such as fresh parsley or basil, a little Italian seasoning, or a dash of tangy lemon zest.
Serve chicken Alfredo with a crusty bread or your favorite side salad.
How to Store
Store any leftover chicken Alfredo penne pasta in an airtight container in the refrigerator, where it'll last 3 to 4 days. For longer storage, store in a freezer safe container in the freezer.
Reheat individual portions in the microwave, and larger portions on the stove or on the saute setting in your pressure cooker.

What is a gradual quick release? Thanks!
Instead of releasing the pressure all at once, you can toggle the release valve back and forth if pasta water begins to spray out.

Grandson absolutely loved this! Thanks
So glad to hear this! Thank you so much!
Just made this for dinner and it is so good! I was worried about the nutmeg, but I couldn’t notice. The only thing I added was a block of cream cheese because, why not?! This is a quick and easy dinner to make, will definitely be making it again!

I am the queen of searching my ingredients to find a quick and easy recipe my little family will all enjoy! This was super easy and delicious! My 20 month old and 6 year old ate it all and licked their bowls. Thank you for sharing!
Thanks! I'm so happy you all liked the chicken Alfredo!
This was delicious and so easy! I had to make adjustments based on what ingredients were available in my kitchen. I used ziti and it worked perfectly. I didn’t have heavy cream either, so I used about a cup of fat free milk and added 4oz of cream cheese to thicken it and it worked very well! Yummy!!
So glad you liked the chicken Alfredo, Beth. Thanks!
