How do you cook dump and start pasta in Instant Pot?

Its easier then you think. Basically all you will need is some base liquid, and pasta that you are planning on cooking.

Follow my step by step instructions for a perfect Alfredo pasta in your instant pot.

If you decided to go with longer pasta noodles, make sure to submerge them as much as possible in to the liquid. Dont stir though, or you will get a great chance of getting a BURN message ( noodles will get stuck to the bottom).

On the picture above you can see that all the noodles are submerged in cream. Perfect!

Its easier to work with small size noodles or just a different kind of pasta. Going to try it with penne next time!

Once the cooking process is over, naturally release the pressure for about 5 minutes and then quick release. Carefully open the lid stir the noodles. If some noodles are stuck together, you can easily stir them with the fork to help. Once all the noodle are nice and separated, its time to add Parmesan cheese.

I use Parmesan cheese from Costco, and then just grate it myself, very easy and tastes much better ( as you may know that there is some wood in your shredded cheeses, google it ).

Keyword: instant pot alfredo pasta
Servings: 4 people
Calories: 440kcal


  • 1 1/2 cup half and half
  • 1 1/2 cup broth i used chicken but you can use vegetarian or beef as well
  • 1/2 lb fettuccine noodles
  • 1 cup parmesan cheese*
  • 2 tspn chopped or minced garlic
  • salt and pepper to taste*


  • Add broth, cream and garlic in to the pot. Place noodles(break in half), make sure then most of the noodles are covered in liquid. Dont stir( You dont want pasta noodles to get stuck on the bottom)
  • Close and lock the lid. Cook on high pressure for 7 minutes. Let naturally release for 5 minutes and the quick release (be careful because the cream may start coming out from the valve, just have a towel close by)
  • Open the lid and separate stuck noodles with a fork. Stir well. Add Parmesan and stir again
  • Add some chopped chives or green onions. Serve.


*Buy Parmesan in blocks if possible. Already shredded Parmesan contains cellulose that is bad for your gut and also may prevent the cheese from melting.
*I prefer to salt and pepper Alfredo pasta after the cheese is already added.

My cream had totally split and separated. My noodles were cooked but I didn’t know how to salvage the cream.

This recipe didn’t work for me either. I wasted a lot of ingredients to get a big lump of undercooked pasta. I tried to fix it on the stove, but it made it worse. I had to toss it all. ☹️

All of the noodles were stuck together after I opened the lid and tried to separate them with a fork. Before starting the Instant Pot and after breaking the fettuccine in half I made sure to follow instructions not to stir the noodles after adding them to the half & half, stock and garlic. Not only were the noodles stuck together in clumps, the sauce was broken, so not even after I added the Parmesan did it ever get creamy. It was a total mess. We tried to eat some of it, but half of the noodles were undercooked and with the sticky, broken sauce, the entire pot got tossed. Please let me know if I did something wrong, because I've gone over the instructions over and over and cannot figure out how I ended up with such a mess.

Hello Lisa, I am sorry the recipe didn't work for you. Did you make sure all your noodles were completely covered with liquid like on the photo in the post? Did you put the exact amount of broth and half and half into the pot as it said in the recipe? This is extremely important. Did you do a natural release? If you didnt that might be a reason that your noodles were undercooked.

You suck
