Have you ever found yourself scrolling through endless casserole recipes only to find that they all use canned soup, white rice, and are topped with breadcrumbs? I know I have. But fear not my fellow apron aces, for I have found the solution to our problem.
Dice the chicken: Place the raw chicken meat on a clean cutting board. Slice it into strips about ½ inch wide. Then cut them across to make small cubes about ½ inch in size.
Dice the onion: Dice the onion to fine pieces
Set Instant Pot to Sauté: Heat the oil in the Instant Pot on sauté mode. This will help to brown the onions and add flavor to the dish.
Cook Onions: Add the onions and cook until they start to brown. This should take about 2-3 minutes.
Sauté the chicken: Add the chicken and sauté until it gets lightly browned from all sides. You need to cook it through.
Scrape the bottom of the pot: Deglaze the bottom of the pot with a small amount of chicken stock. Scrape the bottom enough, so that you loosen any stuck bits.
Add the almond flour: Add the almond flour to the pot. Cook for a minute, whisking constantly.
Add the liquids: Stir in the heavy cream and chicken broth. Bring the mixture to a simmer.
Add the seasonings: Garlic powder, smoked paprika, cayenne pepper, and salt and pepper. Stir everything well.
Add the sour cream and mayonnaise: Add both and stir everything.
Add the broccoli: Add the broccoli florets and make sure everything is evenly distributed in the pot.
Add the cheese: Sprinkle shredded Gruyere cheese over the top of the mixture.
Pressure Cook: Close the Instant Pot lid and sealing valve then set to manual – high pressure – for 5 minutes. Just sit back and let the Instant Pot do the work for you.
Quick release: Do a quick release of pressure by carefully turning the pressure release valve to its venting position.
Finish the casserole: Once all the pressure has been released, you can open the pot. Give it a stir and serve. Enjoy!
