Step 1

In a large zip-top bag, toss in the chicken, cornstarch salt, and black pepper. Shake until well-coated. Set aside.

Step 2

Make the sauce In a small bowl, whisk together all the ingredients for the sauce, set aside.

Step 3

Heat oil in a large skillet over medium-high heat. (You can skip this stove-top step if you prefer or are in a pinch. Just add chicken directly to slow cooker. Chicken will not have that crispy coating) Cook chicken about 2-3 minutes on each side, until lightly browned. Transfer chicken into the slow cooker and pour sauce over top.

Step 4

Cover and cook on LOW for 2.5 - 4 hours or HIGH for 1.5 - 3 hours. (SEE NOTES)

Step 5

About 30 minutes before serving, whisk together the cornstarch and water in a small bowl and stir into the slow cooker. Add the pineapples and bell peppers into the pot. Cover and cook on HIGH for another 20-30 minutes or until the sauce has thickened up and the vegetables are tender. (if your slow cooker is not hot enough to thicken the sauce - pour sauce into a pot and heat on stovetop on high to thicken sauce or you can just skip the cornstarch slurry instead)

Step 6

Sprinkle with sesame seeds, green onions and serve over rice, quinoa or zoodles, if desired.

Step 7

Turn Instant Pot to SAUTE (skip this step and just cook on MANUAL or PRESSURE COOK (high) for 5 minutes if you are in a pinch or prefer. The chicken won't have that crispy coating.) Allow pan to heat up for a few minutes then add oil. Cook chicken in batches (placing the browned chicken on a paper-towel-lined plate) about 3-4 minutes on each side, until lightly browned. Once all the chicken is browned, add back to the Instant Pot and pour sauce over top.

Step 8

Close and seal Instant Pot and set the valve to sealing.

Step 9

Press MANUAL or PRESSURE COOK (high) and set for 3 minutes. Once the 3 minutes is up and the Instant Pot beeps, allow to naturally release for 15-20 minutes. Open lid and transfer chicken to a large serving plate or bowl.

Step 10

Return inner pot back to the Instant Pot. Press the SAUTE button and add additional oil as needed. Toss in the pineapple and bell peppers and cook for 2-3 minutes, until tender.

Step 11

Combine the corn starch with water and stir into the Instant Pot. Allow the sauce to bubble and thicken up. Add the chicken back to the Instant Pot and cook for a minute or two until everything is heated through.

Step 12

Sprinkle with sesame seeds, green onions and serve over rice, quinoa or zoodles, if desired.

Step 13

Prepare your favorite carb (rice, quinoa, cauliflower rice, roasted potatoes, rice noodles) and add to containers. Divide sweet and sour chicken among containers and add any other of your favorite roasted or stir-fried vegetables.
