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 tonight, and it turned out awesome. I know it’s not a full-fat alfredo sauce with cream, and I’m glad, because now I can include it in our dinner rotation regularly without worrying about the fat. I added one chicken breast, following your directions. I cut the chicken into bite-size pieces, salt and peppered them, then sauteed them in olive oil in the IP, along with the garlic according to the recipe. I then took the chicken out of the pot, added the noodles and broth, then added the sauteed chicken back on top of the noodles. I did not change the cook time, and 3 minutes cooked the chicken fully. Seriously, this was so darn tasty and super easy. Hubby and I both loved it. Thanks for sharing your recipe!
I love this recipe but my cheese clumps something terrible!!!
I love an recipe and really impressed my husband with it. I’ve nade it twice and doubled it both times. Only problem I’m having is that the cheese is clumping and the sauce isn’t getting as thick as id like. Any suggestions?
Mines the same a bit soupy. It did thicken up putting it on the Sauté But it’s good I’d use less liquid next time perhaps.
This is by far the best chicken Alfredo recipe I have come across! I am pregnant and trying to eat healthier but all I am craving is pasta so this was a perfect match. Delicious and was so easy to make! I will definitely be making this again!
For a lower fat version of something typically really high in fat, I am quite impressed! Not quite like the real thing of course but still delicious in its own way. And you don’t feel sick after like real rich alfredo usually makes me. Next time I will use more garlic though. Thanks for the recipe!
I used your recipe for the first time on my new Insta pot. I doubled the recipe to use a whole box of pasta. I do not use chicken broth that was low sodium so I cut out half a cup of broth and substituted it with an extra half cup of milk=2.5 cups. I ran out of basil so I used Italian herb seasoning. It turned out amazing! My kids loved it. The noodles did stick together in some parts so I must try to arrange them better in the pot next time. Super recipe & it was quick & low fat! Thank you!
Thanks Alicia, I’m happy you liked it!
I made this exactly as directed, and it was delicious. I doubled the recipe and my family gobbled it up. So easy in the Instant Pot, will make again for sure. Thank you for sharing.
Is the pasta al dente by the end, or softer?
I think it is perfectly tender, not too soft.
Yaass! You knocked it out of the park on this one. Fettuccine is my husband’s all time favorite pasta, but I don’t make it as often as he’d like because it normally takes too long. Not anymore! When I saw this was an IP recipe, I had to try it. And, as advertised, it was delicious. He loved it! Thank you for sharing.
We had this for dinner and it was delicious! I have tried a few of your instant pot recipes so far and each one has been great. Thank you so much!
