Spaghetti tossed in a creamy cheese sauce loaded with mushrooms. If you love mushrooms, this creamy mushroom pasta is going to be your new favorite. Make this amazingly delicious, creamy, dreamy pasta in the instant pot in less than 30 minutes!
When I get the big box of cremini mushrooms from Costco, I make multiple dishes with it. My 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 the 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!

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 – I 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 do not get overcooked when pressure is 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 them 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 and 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 heated the leftovers in the microwave for a minute.

Tried it and was a big hit 🙏🏻
Hi Pavani – So good to hear that. Thank you for sharing it 🙂
Can I use pasta linguine for creamy mushroom pasta in the instant pot?
Hi Kathy – Sure, you can use linguine or any other pasta. Just adjust the cooking time as mentioned in the recipe.
thank you for this recipe MIta..I made it with other type of pasta (not spaghetti) and it came out well just that it was a bit bland. Kids added italian seasoning, cayenne etc on top and then it was good . thanks again
Hi Radha – Thanks for sharing your feedback. Glad to hear you could add additional seasoning and enjoyed it.
I liked this recipe. It was very easy to make. I love mushrooms! I used what I had on hand though, so I used sliced button mushrooms, 2% milk instead of cream and shredded gruyere. I also added a teaspoon of better than boullion garlic broth. I seasoned with black pepper, garnished with green onions, and served with texas toast. It was pretty good and I would make it again!
Hi – So happy to hear that. Thank you for sharing your experience:)
This is such an amazing recipe. Tried it couple of times and everytime it tastes better. My little toddler licked off her plate 🙂
Hi Vandana – So happy to hear that. 🙂
Super simple to make!
I didn’t have vegetable broth so I used turkey stock (that’s what google deemed a suitable substitute) and it worked fine. I also got lazy and used preminced garlic. We love garlic in my household so I added an extra 1/2 a tsp than the recipe required.
My Parmesan cheese melted kind of funky, but i was able to make it work and removed the clumps of melted cheese that formed.
The recipe is good on its own, but next time I’m going to try to add spinach with it 🙂
Hi – So happy to Hear that. Thank you for sharing your experience. 🙂
It tasted really good but there was enough broth to make it a soup. Next time, I will pour some out before adding the cream and parmesan.
Hi Barbara – Thank you for sharing back your feedback. Next time you can add a bit lesser broth, so there is not as much left after cooking the pasta. Glad to hear you enjoyed the taste!
Hi Meeta,
I made this recipe today with mushrooms, spinach, onions and red bell peppers! It came out really amazing! Delicious recipe! Thank you! 🙂
Hi Pranjali – So good to hear that. Thanks for sharing! 🙂
This recipe was very bland. I ended up having to add a ton of seasonings to taste anything other than mushroom. It tasted dirty. I would not make this again.
Hi Dee – Sorry to hear you did not enjoy the recipe. I would recommend to try another recipe if you are not keen on the mushroom flavor.
We really liked this! I used “Better Than Bouillon” Mushroom broth and it was a hit! My husband always likes meat or poultry at every meal, so I served it over shredded chicken for him. I had mine without chicken and I just loved it. We’ll be having a lot of this! Thank you!
So good! Thank you for this recipe! Made it with staples I had in the pantry, mushrooms that were about to go bad, green onions that were on their last leg and cream that I grabbed from a corner store. Was so excited to use things I already had to make something delicious.
