Instant Pot Chicken Alfredo with milk and Parmesan is creamy, saucy and absolutely like a heavy cream restaurant quality Alfredo. Everyone will love this easy 25 minute weeknight dinner!
We love pasta dishes like Instant Pot mac and cheese and Instant Pot spaghetti around here.
Instant Pot Alfredo
I keep this Instant Pot chicken alfredo recipe in my back pocket for nights when we are super busy. Absolutely everyone loves pasta in my house and entire world.
This is skinny alfredo with milk, Parmesan cheese and whole wheat noodles (if you wish). And it is creamy, saucy and absolutely like a real heavy cream restaurant quality alfredo.
It is kid friendly, perfect for picky eaters and Instant Pot beginners. And like my friend, Joy, said in the video below we made alfredo “legal” by adding 3 cups of veggies at the end.
Ingredients for Instant Pot Chicken Alfredo
- Chicken: You want to start with boneless and skinless chicken thighs or breasts. Frozen, half thawed or fresh work. You can also omit meat for vegetarian alfredo.
- Pasta: Fettuccine, linguine or even spaghetti. White, whole wheat or gluten free works.
- Chicken or veggie broth and milk: Broth will create steam and cook everything. Milk is added at the end for sauce.
- Parmesan: I highly recommend to use freshly grated Parmesan and not from a shaker. Completely different taste.
How to Make Alfredo Pasta in Instant Pot
There is video and detailed recipe card below. This is summary.
- Cut chicken or not. I like to cut chicken into 1″ cubes with kitchen shears right above pressure cooker. Or you can lay whole pieces on top and shred after.
- Add liquids: Then add chicken, stock, oil, salt and pepper.
- Layer pasta to prevent from sticking: Break noodles in half and add criss cross in about 6 layers. Doesn’t have to be covered with liquid.
- Pressure Cook on High for 8 minutes for all types of noodles except 5 minutes for gluten free noodles. Wider your noodles, the more bite to them. So, if you like your fettuccine pasta really soft – cook for 10 minutes. I used linguine this time.
- Quick Release the pressure and open the lid. It will be liquidy – do not worry.
- Add slurry, Parmesan and garlic. Whisk cold milk with cornstarch and add to the pot along with cheese and garlic. Stir with tongs separating the noodles.
- Press Saute and cook until thickened. After 2-3 minutes sauce will start bubbling and will thicken.
- Add veggies (optional). As my friend Joy says “we are going to make it legal” with 3 cups of frozen peas. No need to thaw. Stir and let pressure cooker chicken alfredo sit for a minute to melt the peas.
Recipe Tips and FAQs
- You open the pot and it’s not pretty? Don’t worry. Follow the recipe and it will get there. At first, we just cook pasta and chicken and after work on making it creamy.
- Pasta seems undercooked? Stir, put the lid back on and let it sit for 10 mins. It will become softer because pasta absorbs liquid like crazy.
- Sauce thickness: You can adjust thickness by letting alfredo sit more or add more milk at any time.
- Pasta: You can also use penne or any short pasta.
- Milk should be cold otherwise cornstarch will lump. I use 3.5%, higher fat content – creamier sauce. I wouldn’t recommend using any plant-based milk.
- Peas: They don’t have to be cooked. That’s why I like to let peas sit only for a few minutes so they don’t turn pale green and cooked.
- Don’t have Instant Pot? Make this stovetop chicken alfredo.
- More help: Check out this Instant Pot guide and which one I recommend to buy based on your lifestyle and family size.
How to Serve, Store and Reheat
Serving: Sprinkle alfredo with fresh parsley and proudly serve warm to your family. Now, did you hear a lot of “Oh’s” and Ah’s”? I would love to hear from you in the comments below.
Store: Alfredo will keep well in the fridge for up to 24 hours. Pasta gets soggy fast.
Reheat in a small pot by simmering on low while covered with a splash of milk. Stir often and add more milk if necessary.
Do not freeze.

Instructions
- To Instant Pot, add chicken, stock, oil, salt and pepper.

My family loved this recipe, even my picky daughter who was glad it didn’t have onions that the rest of us like. Delicious! Definitely going on the regular menu, but I’ll need to double the batch so we have some leftovers for lunches.
So happy to hear that it won over the whole family Rose!
This was a great, easy and yet again another healthy recipe! I followed the recipe exactly and it turned out wonderfully! It is a real comfort meal!
So glad to hear of the recipe success!
I love love love all your recipes! Especially loved the super easy, chicken alfredo. Also the Beets and feta and so many more. Basically everything I’ve tried of yours have turned out wonderful! Thank you so much! Marianne
Thank you for the kind words, makes our day!
My daughter (10) and I made this and really enjoyed it. I am NOT a cook, but I’m trying and learning! We bought the Gluten free fettuccine 12 oz so used all of it. Probably a mistake! I guess I mis-read, as I only PC for 5 minutes and the noodles didn’t seem done. We also forgot to add the oil–ooppssie! Anyway – I learned the IP doesn’t like you to open/close the lid when it still has the knob up (haha).
Some of the noodles were a little hard, but bearable. We liked it. Probably more yummy the next day! I put some in a bowl w a tad of butter (and salsa for me) and micro for a minute. Perfect!! Can’t wait to try the next one!
I am so happy to read you are trying your hand in cooking. That’s awesome! You can always cook same noodles a few minutes longer next time.
Excellent recipe! Only change I made was used one cup of half and half and one cup of 2% milk. Served with side of peas and roasted cauliflower. Whole family enjoyed it. Next time I may use penne pasta instead of spaghetti. Thank you Olena for another yummy recipe!
You are so welcome!
My husband is allergic to peas. Can you suggest a vegetable I could use instead? Thank you for your great Instant Pot videos!
Finely chopped cauliflower or broccoli.
A delicious easy meal! My family of four loved it and we all had seconds. Thank you so much!
You are very welcome Delia!
This is amazing. So delicious. I am brand new to I. P. and I wasn’t sure about the sauté section and when it said to cook for 5 minutes I wasn’t sure if it meant on the sauté feature or turn the I. P. back on. It ended up that the food burnt on the bottom quite bad, but it wasn’t bad enough to spoil the meal. I will try it again as Chicken Alfredo is one of my favourite meals. So happy I found your website. Thanks for all your hard work in preparing these recipes but most importantly for sharing them with us.
Oh no. You have to pressure cook it on High for 5 mins. There is a video as well unless it’s blocked by your ad blocker. You are so welcome!
I haven’t tried yet. We’re a gluten free house for my husband. Would rice noodles work?
No because they cook so fast, they will just “disappear”. I recommend to use gluten free pasta unless you are talking about brown rice noodles and not stir fry kind of rice noodles. And with gf pasta use less cook time.
Haven’t made yet. If I like a bite to my pasta, how long to cook? Like it al dente and not soft.
Also, recipe says 1-2 cups? That’s a big spread…how much do you recommend ?
Please see steps 3 and 7 in the recipe card.
Love, love this kid-friendly recipe! I have good luck swapping out the milk for Ripple (plant-based) and using Arrowroot powder in place of cornstarch. Yum!
Thanks for sharing your tips/variations Chrissy!
This is my FOURTH recipe that I am trying and you never disappoint. Delicious!
I am just mad at myself for not knowing my instant pot’s full potential! I have shared your site with every mom I know because you save so much time (necessary with virtual school for the kids, school for myself and full time job) and everything is always delicious!
Awe, made my night!!! Thanks so much for sharing!!! I can’t imagine life without Instant Pot! Believe me or not many of my days are behind computer and IP saves the day many nights.
Olena,
Superb! Also followed Kimberly’s advice and sautéed mushrooms and garlic prior to the use of pressure cooker. Used wheat spaghetti which I had to stir and recover after the cook but worked out very well. All this in an Ultra Mini Instant Pot. I especially like the alternatives and substitutions and suggestions you provide in your recipes. Have tried your instant pot recipes for chicken breast and black bean soup; both of which were excellent.
I really appreciate your positive review Vic!
Do you think this would work in the 3 qt. Instant Pot?
Yes. I think you can fit full recipe in there. If not, cut ingredients in half and keep same cook time.
Thank you – this was so good! I added a dash of nutmeg w/the salt and pepper. Delicious. Best Alfredo I’ve ever made and I’ve tried a bunch of recipes! I made the complete recipe in the 3qt. Instant Pot. I used wheat linguine and just needed to add about 5 minutes to the cooking time at the end to get the noodles done. Thanks again!
You are so welcome Cindy! Thanks for the wonderful review.
I omitted the chicken then added a 3 and quarter cup of almond milk instead of regular milk and it tasted great I didn’t wait to 10 minutes so the noodles some of them were a little hard but it was excellent taste and then I let them sit for the 10 minutes thank you so much for this recipe that I can make for my son with no milk
You are very welcome Stephanie!
This is delicious!! My hubby is a big chicken Alfredo fan, and he says it’s better than the restaurant in MI, where he loves the dish! So, so good! Loves it! Added a little red pepper flake for our own pallet.
So happy that you and your husband like the recipe so much!
Delicious and so easy! I’ll never go back to making full fat Alfredo in two different pots. Family loved it. I’m the only one who likes peas, so we enjoyed this with broccoli instead.
So happy to hear this was enjoyed by your family Tam. Thanks for sharing!
I used spaghetti and the top 2 layers weren’t cooked all the way. Any idea what could have caused this? I used spaghetti
I would add 3 mins to cook time. Sometimes altitude or who knows what as it’s a computerized machine… And closing the lid back on finishes cooking pasta quickly if it’s a tad underdone. Pasta cooks fast.
You think this recipe will come out if I use soy milk instead of regular? Due to dairy allergies
It might not be as creamy as full fat dairy milk, but it should turn out good!
Hi Olena
Can I increase the size of this recipe. I only have a 6quart IP, but find it’s not enough for us and my 2 grown sons.
Wondering if I could increase by 1/3?
(Hoping you can save me a huge mess if I try this in my own :))
Yes, should be fine! Even increase by half.
How much milk is omitting the chicken?
Love your recipes. Thank you
Delicious and easy to make.
This was sooo good. I added celery, onion and mushrooms – made it more legal
Can I use skim milk also can’t go to store can I use Swiss cheese. Thx
Using skim milk will result in a more watery, less creamy sauce. I have never tried the recipe with Swiss cheese. It will have a different flavour than parmesan. But up to you if you want to use it!
Finally made it, great recipe thank you so much, I will make this again. Used 5% cream 1 cup and skim milk the other cup….and Parmesan. I am a faithful follower. Diane
I am so happy to hear this Diane 🙂
I followed this recipe exact and the fettuccine noodles were hard and not cooked through. The taste of the sauce was really good. I’m not sure what went wrong.
What pasta did you use? You can add 3 minutes to cook time next time and it will work. Pasta cook time is an easy thing to fix, it is like a sponge and cooks fast. Could be your elevation or Instant Pot as it is a machine. Also some like a bite to them and some very soft fettuccine.
Awesome
You are so nice for coming back and sharing your reviews, Robert. Appreciate it a lot.
Quick. tastey & we don’t miss the cream at all which is brilliant now my man has been recently diagnosed with heart problems & also needs to loose weight. These wonderful recipes along with other’s have helped him to loose 2 stone so far in just under 3 months. Thank you.
Thank you for your wonderful review, Hayley!!!
I am vegetarian, but I made this recipe for my grandchildren while babysitting. I have never seen them eat with such gusto!
I was told, “This is the best meal ever!”
Wow, so awesome!!! All you have to do is pass on the recipe and maybe an Instant Pot to their parents maybe…:)
My family loves this, and it is so quick and easy when I don’t have anything else planned, plus clean up is simple! I’ve made it several times already. It’s very much comfort food. (I prefer spicier dishes so have to add a lot of red pepper flakes on my serving.) We don’t like peas, so I roast some brussel sprouts or broccoli in the oven while this is cooking. Thanks for the great addition to our rotation!
Thanks for your wonderful review, J!!!
I was wondering if it was okay to add the frozen raw chicken and penne pasta together? I wasn’t sure if I had to put them in at separate times. And what if I was to add baby carrots? I am trying to find a recipe using frozen chicken, baby carrots and penne pasta. I am just unsure of the time and exact steps to take. I would appreciate any help you could give me.
Thanks a bunch!
Melissa
Best to follow the recipe. Penne might stick and carrots overcook. Frozen chicken doesn’t work with pasta either.
So very tasty… love it.
Fantastic! Glad you enjoyed the recipe, Steve!
I sauteed mushrooms before adding chicken and pasta, used soy milk in place of whole milk and used frozen broccoli instead of peas. The family loved it!
Yay! So happy to hear! Thanks for taking time from your busy schedule to let me know you enjoyed my recipe, Kimberly.
Very tasty and creamy for not having cream in the recipe. My family loved it. And, it was so easy to make!
That is so amazing to hear! Glad you enjoyed my recipe, Kelly! Whole milk and Parmesan do a good job.
Very delicious my family loved it
I’m glad everyone enjoyed this recipe, Glykeria. 🙂
Great meal – our adopted Ukrainian family love it
Fantastic! Glad everyone enjoyed the recipe, Robert! Feels extra special approved by Ukrainians. JK.
Wow – best fettuccine Alfredo we’ve ever had!
I subbed in part steamed broccoli for peas (family doesn’t like cooked peas for some reason) and put in a bit extra cheese.
This is recipe in number 3 since I.P. purchase. This confirmed to me why Olena loves it so much! Keep those amazing recipes coming!
Yay! Yes, Olena is obsessed for a reason haha. In my super old kitchen and with all the renos and life that happened past year, IP saved the day many times for us. Glad you liked it. Btw, we do not like cooked peas either. I still have vivid memories of a pea mash in a Soviet daycare, with liver burgers. When you add frozen peas, they are raw and just thaw with hot noodles.:)
Olena, this was delish and so easy!!!
