Make creamy Instant Pot Fettuccine Alfredo in just 25 minutes with this lightened-up recipe that uses skim milk, chicken broth, and fresh parmesan cheese instead of heavy cream and butter. This easy pressure cooker pasta is perfectly cooked with a rich alfredo sauce that's healthier than traditional recipes at only 405 calories per bowl.
The easiest Instant Pot Pasta that's healthier, too.
The easiest Instant Pot Pasta that's healthier, too.You literally add everything to the instant pot and walk away. The end result is perfectly cooked fettuccine pasta in a creamy (but healthier) Alfredo sauce. It's so delicious and flavorful, and I can eat a huge bowl without feeling like I need a nap afterward. I often add chicken for extra protein (see notes for how to do that), and did I mention how inexpensive this dinner is? Plus, my kids have no idea it's the healthier alfredo recipe, and everyone loves it has much as our traditional Fettucine Alfredo recipe.

How to make Instant Pot Fettuccine Alfredo:
Add Ingredients: On the sauté setting in the Instant Pot, sauté the garlic in a little oil. Turn it off and break the fettuccine noodles in half and add to instant pot. Pour chicken broth over the noodles, making sure they are all covered.
Cook: Set on manual high pressure for 3 minutes, with a 6 minute natural release. Open it up, give it a stir, breaking up any pieces that stuck together.
Finish Pasta: Mix the cornstarch and milk together and add, along with onion powder, dried basil, and parsley. Stir it up then mix in the grated parmesan cheese and salt and pepper, to taste. Turn the instant pot back to sauté and cook the pasta and sauce until the sauce begins to thicken (it will thicken more after cooling). Serve with a sprinkle of additional cheese on top, and a wedge salad and homemade breadsticks on the side.

I originally shared this recipe July 2018. Updated August 2022 and January 2026.
I made this for dinner and it was so delicious! My husband is not a fan of Fettuccine Alfredo dishes but thought this was pretty good! Thanks for sharing ❤️
This was delicious!!! We doubled the recipe & it worked great! I also added frozen broccoli after I released the pressure for the noodles. I just brought the pot with the pasta & frozen broccoli up to pressure again for 0 mins QR & it was perfect. Then continued on with the remainder of the recipe as written. This was perfect for a cold snowy Sunday. Thank you!!
Could you add the broccoli in the IP as well?
I’d suggest cooking it separately or it will be overcooked and mushy if it pressure cooks.
Would using penne pasta change cooking time or affect the recipe?
That would be fine! Check the cook time on the box or penne and set the IP timer for half of the time. Enjoy!
If you are looking for a healthier version of Fettuccini Alfredo, THIS IS IT! I made this recipe last night and it went over really well! I added cut up chicken tenders, ( sauted first in IP and added before pressure cooking just like instructed in the recipe) and it turned out perfectly. The sauce thickened up beautifully. I love the fact that the pasta is cooked in chicken broth, as you can really taste it! After everything was cooked, I added cooked broccoli to the dish and my nine year old son gobbled it up! (I know! I cannot believe it either!) My super-picky husband had two bowls himself! I added and extra 1/2 cup of parmesan cheese and a dash more of each herb to bring out the yummy flavors. This recipe was SO EASY to make and definitely one I will make again and again!
We made this dish and my daughter loves it.
its so easy for her to practice.
THANK YOU!
Can I double this recipe? is liquid doubled also? (does it mess up heat time for pressure cook?)
Yes, everything will be doubled and the cook time stays the same (the instant pot will just take longer to come to pressure).
Would this do well with soy milk? I have a milk sensitivity, so I can do it with cow’s milk if absolutely necessary, But I prefer to avoid the side effects.
I think that would work fine!
It is one of the best, easy and quick recipes. My kids love it. Love it that its low fat so I can make it more often:-)
Didn’t really follow the recipe procedure. Did it stove top as we added Aldi’s special Seafood ravioli! Yum! The milk and corn starch really helped make it lo fat! Sauteed onions, mushroom, and small shrimp and added to the Ravioli! Next time, the IP!
