Add wild rice and 4 cups of liquid (4 chicken bone broth cubes + water to bring it up to 4 cups) to the Instant Pot and cook on high pressure for 30 minutes, and quick release. The wild rice should be mostly cooked at that point but if not add 10 more minutes. I like my rice to be very soft.

Add the mushrooms and cook for 20 minutes on high pressure and quick release. The mushrooms should be soft at this point but if not give more time to cook.

If your chicken is raw, slice it and add to the Instant Pot. Cook on high pressure for 8 minutes and quick release. If the chicken is cooked slice and add to the pot along with the garlic powder and onion powder and Minor's chicken base and cook for 1 minute on high pressure and quick release.

Taste and adjust seasoning as necessary (I do this using Chicken base rather than salt).
