This creamy Instant Pot Chicken Fettuccine Alfredo is made in the pressure cooker and is ready in less than 30 minutes. This recipe is a "dump and go" and is all made in one pot.
Instant Pot Chicken Fettuccine Alfredo
It is possible to get perfect noodles in the Instant Pot. My trick is to slightly undercook them if I still need to use the Saute after the pressure cooking is done.
Since the noodles still cook during the Saute setting, this allows the noodles to soften up a bit more when adding more ingredients such as the heavy cream and Parmesan cheese. The end result of doing this is that the noodles aren't too soft or mushy.
Also, by breaking the noodles in half, they fully fit in the inner liner of the pot and can all be submerged.

Melting Cheese for the Sauce
I have used shredded cheese when making my own soups and sauces. It works out okay but often times it's stringy instead of creamy and smooth.
I use blocks of cheese that I cut into chunks to melt into my food and the texture is much better than using shredded varieties.
To make the creamiest Instant Pot Chicken Fettuccine Alfredo, use blocked cheese.

Could this recipe be doubled? Is there enough room in the instant pot?
Dana says
Yes, there is enough room to double this recipe. 🙂
Any Gilley says
This is a wonderful recipe ! My family loves it!! Could I use frozen chicken breast in this and if so how can u adjust the time
Dana says
I have never used frozen breasts for this recipe. My concern would be that the pasta would overcook while coming to pressure by using the frozen chicken. I'm happy to hear that your family enjoys this recipe!
Liz P says
Sounds delicious.On step 2 do I remove the chicken completely or just remove the bits that are stuck? I only ask because they are no more mentioned of the chicken.
Dana says
Just remove the bits that are stuck. 🙂 The chicken pressure cooks with the pasta.
Liz P says

Can you add frozen broccoli?
Dana says
Broccoli will turn to mush when pressure cooking this long. I would suggest to cook the broccoli separately and tossing it in the alfredo when serving.
