Add worcestershire sauce, vinegar, and chicken broth to the Instant Pot. Place chicken breasts in the pot.
Add all remaining ingredients to the pot without stirring.
Lock on the Instant Pot lid and set the pressure cooker to manual, high pressure, 15 minutes. Once cook cycle is over, allow the pressure to naturally release for 10-15 minutes before manually releasing remaining pressure.
Shred chicken with forks and mix into sauce.
Notes
How to Serve – Great for BBQ sandwiches, nachos, chicken salad, loaded baked potatoes, quesadillas, tacos, or BBQ chicken pizza.
Leftovers & Storage – Store in an airtight container in the fridge for up to 3–4 days to keep flavors from mixing with other foods.
Freezing – Freeze cooled chicken (with sauce) in a gallon-sized freezer bag for up to 6 months. Thaw overnight in the fridge before reheating.
Using Frozen Chicken – Works great! The Instant Pot will take longer to come to pressure, but no need to change the cook time.
Slow Cooker Option – Place chicken in a Crock Pot, mix sauce, pour over, and cook on low for 5–6 hours.
