Whisk together all of the sauce ingredients and set aside. You want this ready before cooking chicken because once you start cooking, it comes together very quickly. You can adjust spice level to your liking, before or after cooking.
Pat the chicken dry for best results and add the cut bite-sized pieces to a large gallon plastic bag. Add the corn starch and other seasonings to the bag and toss well to coat evenly.
Heat a large skillet or wok to medium-high heat and allow it to get really hot. Add the half of the oil to the skillet and let it heat up.
While oil heats, I like to pour the chicken into a colander to allow any excess corn starch to fall off so I don’t have random chunks of burnt cornstarch in the pan.
Working in batches, add the chicken to the pan in a single layer, making sure none of the pieces are touching one another. Cook for about 4 minutes uninterrupted for a golden-brown sear. Flip the chicken and cook another 3-4 minutes, or until center reaches 165°F or just below. Remove from the pan and set aside and heat remaining chicken.
Once all of the chicken is cooked, shift heat to low. Add the sauce to the hot pan and stir. Simmer for a few minutes, or until the sauce has thickened. Once sauce is ready, add the chicken and stir to coat.
We serve ours over rice with sliced green onions and toasted sesame seeds over top. We also usually add some steamed broccoli. Enjoy!
