This Skinny Instant Pot Fettuccine Alfredo has all of the delicious rich and creamy flavor you love from traditional fettuccine alfredo but it’s lighter and much healthier, with no butter or heavy cream, and a fraction of the calories. If that’s not exciting enough, it’s made in the Instant Pot for a super quick and easy pasta (and even easier cleanup) that your family will LOVE!

I don’t think there are many people who would turn down a cream, cheesy, delicious bowl of fettuccine alfredo, but there’s really something exciting about taking such a high-calorie comfort food and tweaking it to still taste amazing, but be WAY healthier!

One big bowl of this healthier fettuccine alfredo pasta  will barely cost you 400 calories. How’s that possible, you ask? It’s made with skim milk, instead of cream, and there’s not butter or cream cheese. The sauce also has chicken broth, few of my favorite spices, and fresh parmesan cheese, of course. It’s really flavorfully, and creamy, thanks to cornstarch as the thickening agent.

I adapted this recipe for the instant pot from my favorite one-pan skinny chicken alfredo recipe. I love how the instant pot takes all of the prep work out of it! Learn all of my instant pot tips and tricks!

How to make Fettuccine Alfredo in the Instant Pot:

Start by sauteing the garlic in a little oil. Turn the Instant pot off and add the fettuccine noodles, broken in half so they fit into the instant pot.

Pour chicken broth over the noodles, making sure they are covered in liquid before securing the lid.

Cook the pasta on manual, high pressure for 3 minutes, with a 6 minute natural release.

Open the instant pot lid and give the pasta stir, breaking up any pieces that have stuck together.

Process photos for cooking fettuccine noodles in the instant pot including a photo of chicken broth being poured over the noddles in the pot, next to another photo of the cooked pasta in the pot, with a wooden spoon.

Stir the cornstarch and milk together until smooth. Add it to the instant pot, along with the dried basil, parsley and onion powder. Stir it well and then and the freshly grated parmesan cheese. Add some salt and pepper and taste the sauce. Add additional seasonings if needed.

Turn the instant pot back to saute and stir the pasta gently until the sauce begins to thicken. Keep in mind that the sauce will thicken significantly as it cools, so allow it to cool for a few minutes before serving. You can always add some additional cheese or a little more cornstarch slurry, if needed, to thicken the sauce.

Want to add chicken to your fettuccine alfredo? No Problem!

Cut 1-2 chicken breasts into thin pieces, or use chicken tenders, so that they will cook through at the same cook time as the pasta. Brown the chicken in a little oil at the beginning, on saute setting, then remove it to a plate. Then add the chicken on top of the pasta before closing the instant pot lid and cooking.

Can I use gluten free pasta?

You can use gluten free pasta in this dish, but be mindful that it cooks a little fast than regular pasta. Cook for 2-3 min high pressure with a few minutes natural release.

Can I double the recipe?

Yes, you can double the recipe, and use the same cooking time.

    Super easy. Flexible. Changed up the pasta to gemeli and left time the same. Added frozen broccoli with milk and let it come to temp with three sauce. Very family friendly. One pot is a bonus.

  2. 4 stars
    Really good and super simple. I used penne pasta and cooked for same amount of time as the recipe states. I used canned lowfat evaporated milk. At the end, I added some leftover diced rotisserie chicken and stirred it in while the pasta sat and thickened a bit. Served it with broccoli on the side. Delicious and super easy. Will be making this again!
