Ingredients

• 2 6-ounce / 170g grass-fed boneless, skinless chicken thighs
• ½ cup / 60g chopped celery
• ¼ cup / 40g chopped yellow onion
• 1 clove garlic, minced
• ¼ cup / 60ml hot sauce
• 2 tbsp / 28g butter
• 3 cups / 720ml chicken broth
• 2 cups / 226g shredded cheddar cheese
• 1 cup / 240ml heavy cream

Instructions

1. Directions
2. In the inner pot of your Instant Pot, add the chicken thighs, celery, onion, garlic, hot sauce, butter, and chicken broth. Stir briefly to combine.
3. Secure the lid and turn the pressure valve to the “Sealing” position.
4. Select the “Manual” or “Pressure Cook” setting and cook on High Pressure for 15 minutes.
5. Once the cooking cycle is complete, allow the pressure to release naturally for 10 minutes, then carefully perform a quick release for any remaining pressure.
6. Open the lid and use a slotted spoon to transfer the cooked chicken thighs to a separate bowl.
7. Select the “Sauté” function on low. Stir the heavy cream and shredded cheddar cheese into the broth until the cheese is fully melted and the soup is smooth.
8. Using two forks, shred the chicken thighs, then return the shredded chicken to the pot. Stir to combine.
9. Serve immediately, garnished with your favorite toppings.
