Begin by placing the 2 pounds of boneless, skinless chicken breasts directly into the Instant Pot. No need to cut them up beforehand; they will cook down beautifully.
Pour the entire jar (16 ounces) of salsa verde over the chicken. This will infuse the chicken with flavor as it cooks.
Add in the diced jalapeño, 1 teaspoon of chili powder, 1 teaspoon of kosher salt, and 1/2 teaspoon of black pepper. Stir gently to ensure the chicken is well coated with the spices and salsa.
Secure the lid on the Instant Pot and set it to the ‘Manual’ or ‘Pressure Cook’ setting for 15 minutes. Make sure the pressure valve is set to ‘Sealing.’
Once the cooking time is complete, allow for a natural pressure release for about 10 minutes before switching the valve to ‘Venting’ to release any remaining steam.
Remove the chicken breasts from the Instant Pot and place them on a cutting board. Using two forks, shred the chicken into bite-sized pieces.
Return the shredded chicken to the Instant Pot and stir in 1 cup of plain Greek yogurt. Mix until well combined, creating a creamy sauce.
Serve your creamy salsa verde chicken over rice, in tacos, or with tortillas. Enjoy the burst of flavors and the creamy texture!
