Super creamy Instant Pot chicken Alfredo pasta with mushrooms makes a wonderful family-friendly meal that even the pickiest eaters will love!
Nothing beats a bowl of comforting pasta on a cold day! I especially love alfredo sauce and make it all the time, whether it’s just the simple homemade sauce with pasta, this chicken alfredo pasta, or my chicken alfredo tortellini soup that I make in the Instant Pot as well.
This alfredo chicken pasta turns out so rich and creamy quite similar to what you get at Olive Garden! Serve it with homemade breadsticks, and a simple side salad for a complete meal.
How to Make Chicken Alfredo Pasta in the Instant Pot
Set the Instant Pot on the SAUTE setting, and heat the oil. Add the diced chicken pieces, and cook them for a couple of minutes.
Add mushrooms if using, followed by the garlic, herbs, nutmeg, salt, and pepper.
Add the pasta and cover with chicken or vegetable stock. Gently press the pasta with a spatula so that it’s fully covered in liquid (if not, then add more stock of water).
Secure the lid and set the vent to SEALING. Select the PRESSURE COOK/MANUAL setting and set the cooking time for 5 minutes at high pressure. The Instant Pot will take around 5 minutes to come to pressure and start cooking. When the cooking program ends, quickly release the steam.
Carefully remove the lid, and stir in the cream cheese and shredded mozzarella. Stir until the cheese has completely melted. Give the sauce a taste, and adjust the seasonings to your preference.
Garnish with chopped fresh parsley, and extra grated parmesan cheese.
What Size Instant Pot Is Needed?
This recipe is tested in my 6 quart Instant Pot. If you’re using an 8 quart, keep the amount of liquid the same as it’s enough for the 8 quart Instant Pot.
Top Tips
- If you end up using more liquid to cover the pasta, your sauce might be a bit too thin. To thicken it after pressure cooking and stirring in the cheese, stir in 1 teaspoon of cornstarch mixed with 1 teaspoon of water.
- Cooking the pasta for 5 minutes will result in soft but not mushy pasta. If you prefer al dente pasta, reduce the cooking time to 4 minutes.
- If you’re watching your calorie intake or want to make this recipe healthier, use light cream cheese, and omit the mozzarella cheese.
- I used mozzarella cheese, but feel free to add your favorite cheeses!

Would this recipe work with fusilli or penne instead?
Diana says

Jeanie says
I’m a widow , so I don’t a 6 or 8 quart recipe , I need recipes for a 3 guart mini insta pot , any suggestions would be helpful.
Crystal says
You can halve the recipe. Cook times stay the same.
Elizabeth says
Would this work with regular thin spaghetti?
Diana says
Hi Elizabeth, yes you can use spaghetti but you’ll have to break it in half so it fits the diameter of the Pot.
Nanete says
Hi Diana! I love all recipes, cook them every day! Today I’ve tried this one with spaghetti (cause that’s what I had at home), broke it in half to fit, but it didn’t work, the spaghetti got all sticked to each other… :(((
Diana says
Sorry to hear that! It’s because you used spaghetti, and for spaghetti to work in the Instant Pot you have to break it into pieces that can fit the pot, then pile them up but use alternating directions to avoid them from sticking to each other. You can see a picture here https://nourishplate.com/instant-pot-spaghetti-and-meatballs/ I hope this helps!
