Place chicken breasts on a plate and season with onion powder, garlic powder, salt and pepper on both sides. Set aside.
To Instant Pot, add chicken broth, 1/2 cup barbecue sauce and chicken breasts. Close the lid, set pressure vent to Sealing and press Pressure Cook on High or Manual for 15 minutes.
After wait 10 minutes, then turn valve to Venting to release remaining pressure. Remove chicken onto a plate and drain any liquid.

Notes
Store: Leftovers in an airtight container for up to 5 days.
Freeze: Up to 3 months. Thaw in the fridge overnight. Reheat in a pot by simmering on low with a tiny splash of broth.
Frozen chicken breasts: Just make sure they are separated and cooking time remains the same.
BBQ sauce: We like to use healthier ones like Stabb's or homemade.
Pulled chicken: You can also shred breasts with 2 forks and return to the pot with sauce and some saved cooking liquid.
