When I get the big box of cremini mushrooms from Costco, I make multiple dishes with it. Mornings start with sautéed mushroom omelette, then make Mushroom & Green Peas Curry, this creamy mushroom pasta and mushroom soup. But I have to say the best of all is this Creamy Dreamy Mushroom Spaghetti. It is simple, quick and sooooo good!
Whenever I make this pasta, the kitchen fills with the wonderful aroma. It is such an amazing comfort food, especially during the Fall. As I am typing this post, I am enjoying a bowl of leftovers of this pasta 🙂
I love to use instant pot to make pasta as it is one-pot (yay for less cleanup). Also, when we make pasta in the instant pot, we do not drain the water, which makes the pasta so much better and creamier!
I recently received wonderful matte dinnerware from Tuxton Home. They offer high quality, innovative cookware & dinnerware for the modern lifestyle. I used their white pasta bowls to shoot the photos for this recipe. I have to say these are the best matte bowls I have found. They are very durable, and can go from freezer to oven to table – Microwave, dishwasher, freezer, oven safe (to 500°F). Give Tuxton products a try, I am sure you will love them too.

Main Ingredients to make Creamy Mushroom Pasta
Just a few ingredients are required for this pasta. I am also sharing my tips for ingredients and any possible alternate options below.
- Mushroom – I used cremini mushrooms, but feel free to use other varieties. I feel that the more earthy cremini mushrooms add a much better flavor to this pasta.
- Spaghetti – You can also use whole wheat spaghetti noodles. They do hold up well when cooked in the instant pot.
- Garlic – Can’t do without it!
- Onion – I love to saute some onions in this pasta. It adds a lot of flavor!
- Broth – I used vegetable broth. But other broths would work just as well.
- Parmesan – I have tried this recipe with parmesan and pecorino romano. Both work great. Use cheese from a block, and not the pre-shredded one.
- Cream – Use heavy whipping cream. Feel free to adjust the quantity to make this lighter.
How to make Creamy Instant Pot Mushroom Pasta?
This is a very easy recipe. The main effort involved is slicing and sauteeing the mushrooms before cooking the pasta. I like to saute the mushrooms and take them out, so they are not getting overcooked when pressure cooking the pasta.
- Slice the mushrooms.
- Heat the instant pot on sauté mode and add olive oil (or butter if you like)
- Add the mushrooms and sauté for 4-5 minutes while stirring frequently. The mushrooms will release their water and then brown nicely.
- Take the mushrooms out on a plate and keep aside for later.
- Now in the same pot (no need to clean), add another tablespoon of oil and then sauté the onions and garlic for a couple of minutes. Turn off the instant pot.
- Add the broth and deglaze the pot making sure nothing is stuck to the bottom.
- Break the spaghetti noodles in half and spread them making sure all the spaghetti is covered in broth.
- Pressure Cook the pasta noodles. The general rule of thumb is to pressure cook for 1 minute less than half the time on the pasta box. Then quick release the pressure.
- Add the cream, parmesan and stir well until the cheese melts.
- Then add back the sautéed mushrooms and stir well.
- Adjust salt and pepper to taste. Add the lemon juice and mix it.
- And the delicious mushroom pasta is ready to be enjoyed!
Oooh…that creamy cheese sauce.
This pasta is best served right after cooking. However you can definitely enjoy it later too, as I did. You can add more cream or broth if needed. I heat the leftovers in the microwave for a minute.

I made this tonight. I used my 3 qt mini so I had to add a little extra liquid as the level of the dry pasta was not covered by the liquid. My spaghetti package said 7 to 9 minutes stovetop so I set it for 4 minutes. That time wasn’t quite enough but by the time I cooked off the extra liquid, it was just right. Just a little clumping which wasn’t an issue as I had extra liquid. My first couple of attempts with pasta in the IP didn’t go too well, but this worked out nicely. A little thyme wouldn’t go amiss. It’s a natural with mushrooms. Also, since I was working with my IP mini with a small surface area, I just sauteed the mushrooms in a separate pan. A couple of people have noted that more protein would be good. Maybe some hummus after cooking? It doesn’t have a strong flavour
Could this be made adding chicken for a boost of protein? I have made recipes where you sauté first and some where you put it in uncooked.
Can this recipe be doubled in the instant pot. Just wanted to make sure there is enough room. I have the 6qt. Thank you!
There would be room but you might need a little extra liquid as the level of pasta would be higher.
Hi Carole – yes, this recipe can be doubled in a 6qt instant pot. Hope you enjoy the pasta!
This was soo good! I messed up the pressure cooking time so the spaghetti got stuck to the bottom but even with that little mishap, this was DELICIOUS. Thank you!!
Hello, Can i substitute it with broccoli and can i add water instead of broth? Thanks.
Hi Krishna – You can use broccoli, however I would add it after pressure cooking the spaghetti. Then cover with the lid and let the pasta with broccoli rest for 5 minutes. Water will be fine too in place of broth. Hope you enjoy the pasta.
Creamy looking Pasta. Love the pic in the instant pot.
