  • Instant Pot


  • 1 1/2 pounds boneless chicken breasts
  • Sea salt and pepper to season chicken to taste
  • 3 tbsp avocado oil or oil with high smoke point, divided if dairy-free isn't important, you can use butter or ghee
  • 8 oz white mushrooms washed and sliced
  • 1 small white onion peeled and chopped
  • 3-4 cloves garlic, minced to taste
  • 1 tbsp Italian seasoning
  • 2 cups stock or broth
  • 1/2 cup full-fat coconut milk if dairy-free isn't important, you can sub heavy cream
  • 4 tsp tapioca or arrowroot starch can sub cornstarch
  • 3-4 handfuls baby spinach


  • Season both sides of chicken with salt and pepper.
  • Turn your Instant Pot to sauté and add 2 tablespoon oil. Once hot, add the seasoned chicken and brown both sides of chicken. About 3 minutes per side.
  • Remove chicken from Instant Pot with tongs and set aside for a moment.
  • Add remaining oil to the Instant Pot. Once hot, add onions, mushrooms and garlic. Cook, stirring occasionally, until the mushrooms are tender. About 5 minutes.
  • Season with more salt and pepper if desired.
  • Turn off your Instant Pot. Add broth/stock and Italian seasoning. Use a wooden or long spoon to scrape and deglaze the bottom of the Instant Pot.
  • Add chicken back to the instant pot and lock lid into place and make sure valve is switched to sealing.
  • Cook on HIGH pressure for 5 minutes. If your chicken breasts are extra thick, consider cutting them in half or adding an extra minute or two the cooking time. It will take your Instant Pot about 7-10 minutes to get up to pressure
  • While chicken cooks, mix the tapioca/arrowroot and milk, whisking until lumps are gone. Set aside.
  • After cook time is over, quick release the pressure and carefully open the lid.
  • Remove the chicken and place on a cutting board or plate.
  • Add coconut milk mixture to the mushrooms and stir to combine.
  • Again, turn your Instant Pot to the saute function and let everything cook for about 5 minutes or until sauce thickens.
  • Taste and season as needed. If sauce is too thick, add a little extra broth to thin it out.
  • Add spinach. Stir a few times to incorporate and to slightly wilt the spinach in the hot sauce.
  • Slice chicken if desired and stir back into the sauce
  • Serve warm with rice, pasta, steamed/roasted veggies, baked potatoes or quinoa.
