Step 1

Pat chicken dry and sprinkle generously with salt and pepper. Set the pressure cooker to the saute setting at high heat. Add in oil. Working in batches sear chicken until golden brown, about five minutes on each side, adding more oil as necessary. The chicken should not be fully cooked at this stage but the skin should be nicely browned. Transfer chicken to a plate and set aside.

Step 2

Add onion, carrots, peppers, and mushrooms to the pressure cooker and saute until vegetables are soft, scrapping up browned bits, about 4 minutes. Add garlic, oregano, and red pepper flakes, and cook until fragrant, about 1 minute. Add bay leaf, chicken broth, tomatoes, fresh thyme, fresh parsley, and balsamic vinegar. Return chicken to pressure cooker and press into tomatoes until they are mostly covered.

Step 3

Place lid on pressure cooker and lock in place. Cook on high pressure for 12 minutes. Release pressure using quick release valve and remove lid. Remove bay leaf. Season to taste with salt and pepper. (If a thicker sauce is desired, you can remove the chicken to a plate and simmer sauce until it is the desired thickness. Do this before seasoning to taste with salt and pepper.)

Step 4

Garnish with parsley and serve over rice, cauliflower rice, or gluten-free pasta.
