Season the chicken legs generously with kosher salt and freshly ground black pepper. Turn an Instant Pot® to the high saute setting and add vegetable oil. Once oil is shimmering but not smoking, add half the chicken pieces to the pot and brown on both sides, about 7 minutes. Remove the browned chicken pieces with tongs to a plate and repeat the process for the remaining chicken.

Return all the browned chicken pieces to the Instant Pot®. Add soy sauce, sugar, vinegar, garlic, bay leaves, onion, and 1/2 teaspoon of freshly ground black pepper. Follow the manufacturer's guide for locking the lid and preparing to cook. Set the Instant Pot® to pressure cook on high for 8 minutes.

After the pressure cook cycle is complete, follow the manufacturer's guide for quick release. Wait until the quick release cycle is complete. Carefully unlock and remove the lid, taking caution with any remaining steam. Turn the Instant Pot® back to the high saute setting. Bring the sauce to a boil and reduce it until dark brown and thickened, about 20 minutes. Remove the bay leaves.
