Homemade instant pot teriyaki chicken recipe is the perfect weeknight meal that's ready in 20 minutes! The juicy and tender shredded chicken is covered and cooked in a sweet and sticky sauce.
Whisk together soy sauce, light brown sugar, water, red wine vinegar, crushed red pepper flakes, garlic, ginger, black pepper, red wine vinegar, and cornstarch together in a small mixing bowl.
Place thawed or frozen chicken breasts in the instant pot, add the combined sauce over the chicken breasts.
Place the lid on the instant pot, select manual pressure, then high pressure, and add 10 minutes for thawed chicken breasts or 20 minutes for frozen chicken breasts.
Once the instant pot beeps, allow the pressure to release naturally until the valve is down. Take off the lid and shred chicken breasts.
Serve and garnish with sliced scallions and pineapple chunks.
