Instant Pot mushrooms and onions you can make in just 10 minutes! Our favorite Instant Pot vegetables side dish served with chicken or beef comes out perfect every time. Sauteed and steamed with butter and garlic to tender.
We made Instant Pot mushrooms and onions the other night with chicken and WOW were they good! So good I thought we’d share our easy Instant Pot recipe with you. (affiliate links present)
Ninja Foodi Mushrooms
I mean even if you weren’t a fan of this brown veggie you may just fall in love with them prepared like this! You can make them in your Ninja Foodi using the lid that is not attached, or Crockpot Express as well as this brand of pressure cooker.
You want them buttery, tender and savory with every single bite. You can use canned, white button or baby bella mushrooms for this, but we think the brown latter and a bit firmer version is better. Test for yourself and see.

If you are new to pressure cooking we have a lot of easy one pot meal recipes for you here. To begin with let’s start with a few basic tips:
- Make sure to Bookmark our InstaPot recipes page. We add new ones each week!
- Then PRINT this —–> Instant Pot cooking times cheat sheet that will help you understand how long meat, vegetables and beans take to cook in your pressure cooker.
- I HIGHLY recommend you buy this non stick pot.
- You should still deglaze pressure cooker after sautéing but it won’t have as many issues with this better liner.
For reference, this is the pressure cooker I have (a 6 quart) and use for all recipe creations.
Mushrooms in Instant Pot
Yes!! This was literally one of those “this would be good, I have some of that, and let’s try this” side dish. They don’t always work out the first time I try them but this one did. May be one of our favorite Instant Pot vegetables thus far. You just need a few ingredients such as:
- Baby bella mushrooms
- they have a better texture than button I feel
- work great in a casserole too, like our Instant Pot cream of mushroom rice dish
- Onions
- Butter or olive oil but butter is better
- Minced garlic
- Garlic salt
- Broth
- Parmesan cheese on the top is fantastic
Can I use white mushrooms instead of baby bellas?
Of course you can substitute one for the other in general. In this case the latter will hold up better and not get so soft and mushy under high pressure. That is why I suggest using the deeper brown version. If you want to cook button as they call them instead I would cut the timing in half.
Here are a few questions you might have in mind before you get going:
The simple answer is that white or button mushrooms are lighter in color and softer, especially when cooked. Bellas are harvested at an intermediate stage of maturity in the growing process.
This answer is up for debate. You don’t want to “wash” them and need to be very gentle when removing dirt. You can either use a damp paper towel or run over cold slowly running water to do this.
They’re all pretty healthy to eat if you don’t add a bunch of fat or sodium to them when cooking. Oyster and shiitake have the most fiber, where portobellos are among the highest in vitamin D.
Absolutely. Once you have wiped the dirt off you can cook them as is, or remove stems if you’d rather.
I don’t steam them, I saute and pressure cook them in the sauce. It is way better this way I tell you!
This is what bellas look like and are usually about the same price as the ever popular white mushroom (or button) variety. I use these in many dishes like to make air fryer stuffed mushrooms and our air fryer vegetables too because they don’t fall apart as easily.
Instant Pot Portobello Mushrooms
- To keep them a bit firm as well I didn’t slice or halve them either.
- The larger you keep them the longer you can cook them to draw in those other great flavors.
I tend to under season to begin with and test when it’s done. Adding a bit more salt and pepper once they’re done is better than having too much. You can’t fix over seasoned anything really. I kid you not, pressure cooking has changed my life!
How long to cook mushrooms in Instant Pot
Under high pressure it certainly doesn’t take very long at all, only 5 minutes but you do need to wait until it comes to pressure so that would add to the timing. On the stovetop with the lid on would take the longest, or maybe the oven might be a tie.
How do you use a pressure cooker for mushrooms?
Time needed: 9 minutes
Pressure cooker mushrooms
- Saute
Set pot to saute and add your butter, garlic and diced onions. Allow butter to melt and onions to soften a bit.
- Clean mushrooms
Clean dirt off shrooms with a wet paper towel or run under slowly pouring cold water just to get debris off. Put on a few paper towels and roll up gently to get water off the outside of them.
- Add ingredients
Add mushrooms into pot with onions. Saute for 3-4 minutes stirring often (but gently) just to soften slightly. Turn pot off.
- Cook
Close lid and seal release valve. Set to high pressure for 5 minutes followed by a quick release.
- Serve
Use a slotted spoon to lift out sauteed mushrooms and draining juices. Leave extras in pot with butter sauce until served.
When using an Instant Pot I always use wooden utensils, a slotted spoon is my favorite one. I use it for everything.
How long to cook canned mushrooms in pressure cooker
I don’t know why you would feel the need to do this since they are already quite soft and you just need to microwave for 30 seconds to warm but if you really wanted to you could. I would just use the first part of these instructions, drain your can, add in with onions and garlic and warm that way on saute.
- Essentially what you’ll have are perfectly cooked sauteed mushrooms once they’re done.
- Why do I prefer this method? Because I don’t have to stand and watch them for 15 minutes at the stovetop like you would with boiled mushrooms.
- It’s just add garlic and mushrooms in the pot and set to high pressure for a few minutes with a quick release at the end.
If you wanted to double this amount I would set the cook time for the same amount. Of course the softer you want them the more minutes you’d need. Five seems perfect for us, not mushy at all.
You can print recipe below, or come back here often because we love “seeing you”. 😉 If you’re looking for other easy InstaPot recipes we have a bunch! You can use our Instant Pot vegetable cook times sheet here to determine how long each food takes.
Our pressure cooker green beans are incredible too, my daughters’ favorite side. Ok, our air fryer green beans may be a close second.

@The Typical Mom, The recipe card directs it on step 3, the story version of the directions does not. These came out awesome, thanks!

Used mY instant pot for first time today. I love your directions. Very easy to understand. I threw in spinach and Cajun season ( the no salt added ). It was great! Tomorrow I think I will make creamed version. By adding flour during sautéed phase of onions, I also chopped up steams and added during this phase. Maybe some jalapeño. I have an over abundance from my garden.
Thank you for sharing, Josephine
