Tender Instant Pot Creamy Chicken Marsala that's dairy-free & gluten-free with Paleo AIP, Keto & Whole30 options.
Combine coconut flour, Italian seasoning, and garlic powder in a medium bowl. Season with salt and black pepper, as desired, and stir to combine.
Place chicken breasts in a one-gallon plastic freezer bag and pour seasoned flour mixture on top. Seal bag and turn several times until chicken is evenly coated.
Select SAUTE function on Instant Pot® and set to high. Add one tablespoon olive oil. Once hot, remove chicken from bag and shake off excess flour mixture. Add enough chicken to cover bottom without overcrowding. Work in batches, if necessary.
Brown chicken on each side, approximately 3 minutes per side. Remove and repeat with remaining chicken, adding more olive oil as necessary for each batch.
Add 1 Tbsp more oil to Instant Pot®. Add Portobello mushrooms and red onion. Cook, stirring frequently, until mushrooms turn brown and the onions soften, approximately 5-6 minutes.
Add sherry vinegar and chicken broth and deglaze bottom of the cooking container by gently scraping up the brown bits with a plastic spatula.
Turn Instant Pot® off and add browned chicken to the pot and cover. Lock the lid and set the pressure valve to SEALING. Press the MANUAL button and adjust setting to HIGH. Set cook time to 10 minutes.
When cook time is finished, allow pressure to release naturally for 10 minutes, then press CANCEL. Do a quick release for any remaining pressure. Turn the unit off and remove lid. Use tongs to transfer chicken to a serving platter and rest for 5 minutes, leaving the hot liquid inside the Instant Pot®.
To make the sauce, press SAUTE. When the display reads HOT, whisk cashew milk (or coconut milk whisked with 1 Tbsp arrowroot starch) into the hot liquid in the Instant Pot®. Simmer, whisking constantly, until mixture is thickened, about 5 minutes.
Press CANCEL then add chopped parsley to the pot. Season with salt and black pepper, to taste, and stir to combine.
Top each chicken breast with some of the creamy mushroom sauce and serve immediately. Enjoy!
Serve your Instant Pot Chicken Marsala over cauliflower rice, roasted vegetables, spiralized zoodles, sweet potato starch noodles, or cassava pasta!
