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 wonder if this would work with gluten free rice pasta and almond milk.
Hi Connie - Almond milk will be fine. However gluten-free pasta may not work as well in the instant pot.
This was very easy and delicious! My kids (2, 5, and 9) all ate a ton and asked for a 3rd serving. I made a few minor adjustments based on what I had on hand. I used a 1/3 cup whole milk and 2.5 tablespoons of cream cheese, as I was out of heavy cream. I also used chicken broth instead of the vegetable and added 2 cups cooked chopped chicken after the noodles for the pressure cook.
Will be going in our rotation! Thank you for such an easy quick recipe.
Hi Lindsey - So happy to hear that. Thank you for sharing your experience 🙂
We don't hace an instant pot anymore, we just never rely liked using it TBH. I'd like to make this sauce though. Would the amount of ingredients be the same if making on the stove with a regular pot or skillet?
Hi Jennifer - You can follow the same recipe on stovetop. The only difference would be that you will need more broth about 3-4 cups. Once you have added all the ingredients before the pressure cooking step, bring to a boil, then simmer on low heat for 15-20 minutes until most of the liquid is absorbed. Hope you enjoy it!
This is one of my favourite recipes! Do you know if it would freeze well?
Hi Eve - Thank you. Sorry, I don't think this pasta will freeze well.
This dish is awesome. We bbq’d steaks and this was our side dish. My dad is super picky and he loved it! Thanks for sharing such a great recipe.
Hi Lori - So good to hear that. Thank you for sharing it back 🙂
Can you sub milk for heavy cream?
Hi Summer - I have not tried, but I think it will work well but the pasta will be a bit less creamy. You can also use half and half if you have that.
This. Was. Amazing!
Hi Leanna - So good to hear that 🙂
