Add the chicken, sweet potatoes, onion, broth, and spices to the Instant Pot and stir to combine.
Put the lid on and set the valve to sealing. Set to cook on manual high pressure for 12 minutes.
Allow the pressure to release naturally for 10 minutes, then release teh remaining steam if needed and remove the lid.
Scoop out about half of the sweet potatoes along with the liquid, and transfer to a blender. Add the coconut milk and lemon juice, and blend until smooth.
Stir back into the Instant Pot with the chicken and veggies and season with salt & pepper to taste. Heat on the "warm" setting until warmed through.
To serve: scoop over steamed cauliflower rice, white rice, or roasted vegetables. Enjoy!
