Instant Pot Mushrooms
This is how to cook mushrooms in Instant Pot with onions quick! This is our favorite vegetable side dish served with dinner that come out perfectly tender 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 we thought we'd share our easy Instant Pot recipe with you.
We mean even if you weren't a fan of this brown veggie you may 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.
This was one of those “this would be good, we have some of that, and let's try this” side dish. They don't always work out the first time we try them but this one did. May be one of our favorite Instant Pot vegetables thus far.

Ingredient notes
You will have the best results using Baby bella mushrooms in this case. They have a better texture than the white or button type we feel. These work great in a casserole too, like our Instant Pot cream of mushroom rice dish. If you have any left we recommend you use them in this dish.
To saute and cook we will use salted Kerrigold Butter or olive oil, but butter is better. You could use a dairy free alternative as well except that is typically unsalted so we would add an extra pinch in that case.
You will want some broth for the liquid. For seasonings to add flavor we will add a bit of Minced garlicgarlic salt.
Can you add onions?
Yes, we do like to add yellow Onions that have been diced with this. The two together is a nice duo. It is not necessary but an easy way to add texture and flavor to the dish.
Can you add potatoes?
You could but they would need to be peeled and diced into small bite size pieces, about 1/2″ cubes in size. If they were larger they may not cook all the way thru to become tender in the short cook time. You could add 1-2 medium sizes.
We 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. We kid you not, pressure cooking has changed our life!

This is what bellas look like and are usually about the same price as the ever popular white mushroom (or button) variety. We use these in many dishes like our air fryer vegetables too because they don't fall apart as easily.
How Long to Cook Mushrooms and Onions in Instant Pot
To keep them a bit firm we didn't slice or halve them. The larger you keep them the longer you can cook them to draw in those other great flavors. The cook time will reflect them being cooked whole at 5 minutes!
Can you 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 we suggest using the deeper brown version. If you want to cook button as they call them instead we would cut the timing in half.

How Long to Cook Canned Mushrooms in Instant Pot
We don't know why you would feel the need to do this since they are already quite soft and you need to microwave for 30 seconds to warm but if you wanted to you could. We would 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 we prefer this method? Because we don't have to stand and watch them for 15 minutes at the stovetop like you would with boiled mushrooms. It's 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 we would set the cook time for the same amount. Of course the softer you want them the more minutes you'd need. Five seems solid for us, not mushy at all.
Can you cook frozen mushrooms in Instant Pot?
In general you don't find them frozen but occasionally you could. Like other dishes under high pressure the cook time wouldn't change. 5 minutes successfully cooks frozen or fresh mushrooms to fork tender. We will say that the texture from frozen is mushier and not as pleasant, but yes it is possible.
When using an Instant Pot we always use wooden utensils, a slotted spoon is our favorite one. We use it for everything.


Kitchen questions
What is the difference between white and baby bella mushrooms?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.
How do you properly clean mushrooms?This answer is up for debate. You don't want to “wash” them and need to be gentle when removing dirt. You can either use a damp paper towel or run over cold slowly running water to do this.
Which mushrooms are the healthiest?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.
Can you eat the stems of baby bella mushrooms?Absolutely. Once you have wiped the dirt off you can cook them as is, or remove stems if you'd rather.
How do you steam mushrooms in Instant Pot?We don't steam them, we saute and pressure cook them in the sauce. It is way better this way we tell you!
