1 First, You need to make your roux.
You want equal parts of oil and flour.
Turn your Instant Pot on Sauté and add 1/2 a cup of oil. Once heated, mix in your 1/2 cup of flour.
You need to stir it often until it starts reminding you of peanut butter…
Add in your powdered seasoning, slowing mixing in.
Then add in your Trinity (Onions, Peppers, and Celery) – sauté in the instant pot for a few minutes until soft.
Slow add in about 1/2 your broth – mixing in the roux.
Add in your raw chicken. (You can use fresh or frozen chicken in the Instant Pot!)
Add in the rest of your broth.
Use the “Soup” function.
For Fresh Chicken: set to cook for 20 minutes. For Frozen Chicken: set to cook for 30 minutes.
Let it naturally release for 12 minutes, then manually release the rest of the way.
Pull out cooked chicken and shred it, then add it back to your soup.
(optional: After it is cooked, if you like a thicker gumbo, you can mix 2 tablespoons of arrowroot or cornstarch in a little bit of water and mix in your soup)
