This Keto Instant Pot Chicken and Mushrooms is even more wildly delicious than it looks. Tender, juicy chicken pair perfectly with sautéed mushrooms. For a complete meal, serve it over cauliflower rice and top it off it feta, olives, and parsley. So ridiculously easy! No Pressure Cooker? No worries! I've got slow cooker instructions too.

While I was late to the pressure cooker game, I am most certainly making up for lost time.
I didn't get one until last year, mostly because I didn't understand why I needed another kitchen gadget.
I already had a slow cooker, did I need an Instant Pot?
Obviously, a pressure cooker cooks things quickly (duh!), but given that I work from home I felt that my crock pot worked just fine for my lifestyle.
Then I finally took the plunge. Immediately, I fell in love and regretted not getting one sooner.

There is something amazing about the way flavors develop in an instant pot. I love being able to throw together a meal in a flash, even if I haven't planned ahead.
This recipe is the perfect example. The chicken is perfectly tender and infused with so much flavor from the vegetables, broth, and sherry. It is hard to believe it is so effortless to make.
I opted not to make this a creamy dish, but if you are in the mood, by all means, throw in some cream cheese. (I added some with the sauce when I reheated leftovers and it was amazing.)
On the other hand, if you are dairy-free, just skip the feta or use a nut-based feta alternative.
Either way, I know this is one you are going to love it!
Frequently Asked Questions
Can I make Creamy Instant Pot Chicken?
Yes! Cook as directed. When the cooking time is up and you have released the pressure, add 8 ounces of cubed cream cheese to the pressure cooker. Return the lid to the pot and let it sit until the cheese melts. (You can also add the cream cheese prior to cooking.) . If the sauce is too thin, you can add about ¼ teaspoon of xanthan gum. Stir to combine. If it is too thick, add in more broth, 1 tablespoon at a time. I love it this way served over Zucchini Noodles.
How long does this recipe keep in the refrigerator?
This should last well for three or four days. It is great leftover!
Can you freeze this recipe?
Without the cheese, this recipe can be frozen for up to 3 months.
Can I cook frozen chicken in the Instant Pot?
Yes. You can used cubed frozen chicken in this recipe. Increase the cooking time to 12 minutes.
My Instant Pot isn't coming to pressure. How can I fix this?
The pressure release on your pot has two positions that it can be set at, Sealing or Venting. The pressure release (or steam release) has to be set to sealing for the pot to come to pressure. So make sure that your pot is set to sealing. You also need to make sure that the ring is properly secured in place. If it is loose the pot will not come to pressure. Sealing rings have a life of about a year, so if you continue to have an issue once the ring is seated properly in the lid, it may be time to replace it.

How would I cook this without the Instant Pot?
Wendy
You could easily do it on the stove top. Just follow the instructions in the beginning and cook it over medium heat until the chicken is cooked through.
Marc Filippone
I thought this might taste sort of bland, but I was pleasantly surprised. The feta (I used goat cheese) and olives added at the end are the kicker. Next bowl of this I have I'll put more of each.
Wendy Polisi
Glad you enjoyed it! I'll bet goat cheese was amazing. I will try that next time.

Are Greek spice mix or Italian seasoning the same as Mediterranean?
Wendy Polisi
They are a little different but both would work.

Can I use red wine vinegar as a substitute for sherry? If so, how much would be equivalent? If not, is there another substitute I can use in place of the sherry?
Wendy Polisi
I haven't tried it but you could try using a tablespoon or two of vinegar.
Kirsten
Hi, I live in a dry country (no alcohol). I can’t get Sherry... what could I sub?
Wendy Polisi
I actually use cooking sherry, which has no alcohol. It is with the vinegars and you don't need to be 21 to buy it. If you can't find that you could add in a tablespoon of white wine vinegar for a little acid.
