Steps
Place the butter to the Instant Pot and hit Sauté and Adjust so it's on the More or High setting. Once melted, add the mushrooms, shallot, and bell pepper. Sauté for 3 minutes until slightly softened.
Add the chicken and sauté for 2-3 minute more, until the chicken is pinkish-white in color (it should not yet be fully cooked).
Add the broth, garlic powder, seasoned salt, pepper and stir well. Secure the lid, move the valve to the sealing position, and hit Cancel followed by Manual or Pressure Cook at High Pressure for 4 minutes. Quick release when done. Timing note: the source allows 10 additional minutes beyond prep and pressure cooking, for 24 minutes total.
Meanwhile, as the pot's pressure cooking, bake the biscuits according to the package's (or your meemaw's) instructions. Prepare the cornstarch slurry now as well by mixing together the cornstarch and water.
Once the pot's done pressure cooking, it won't look too pretty - but that will soon change! Hit Cancel followed by Sauté and Adjust to the More or High setting. Stir in the cream, Boursin (or herb cheese), roasted red peppers, and frozen peas (the heat from the pot will quickly thaw and cook the peas). Stir until all is combined and a lovely sauce has formed.
Once the pot begins bubbling, stir in the cornstarch slurry and let bubble for 30 seconds until killing the heat. Stir in the Parmesan until well-combined and then you're all set! (NOTE: For a thicker sauce, see Jeff's Tips)
Ladle the goodness from the pot over the plated biscuits and you have yourself some Chicken a la Queens!
