Trim any excess fat from the chicken thighs and cut into bite-sized pieces, about 1-inch. Whisk together cornstarch, flour, salt, and black pepper in a large bowl. Add chicken pieces and toss until all are completely coated.
1 ¼ lbs. chicken thighs, ¼ cup cornstarch, ¼ cup flour, ¾ tsp. salt, ¼ tsp. black pepper
Heat 1-2 tablespoons of oil in a large stainless-steel skillet or wok over medium to medium-high heat. Wait for the oil to sizzle and add in half of the coated chicken pieces. Make sure to shake off any excess starch/flour coating before adding to the skillet. Cook for 7-9 minutes, flipping over halfway through. Remove the cooked chicken and let drain on a paper towel-lined plate. Repeat with remaining 1-2 tablespoons oil and chicken.
3-4 Tbsp. oil
Whisk together the sauce ingredients in a medium-sized bowl. After chicken is removed from the skillet, pour in sauce, turn heat to high, and bring to a boil. Once boiling, reduce heat to low and cook for 1-2 minutes, whisking constantly. The sauce should reduce by almost half during this time.
¾ cup orange juice, ¼ cup tamari, 3 Tbsp brown sugar, 2 Tbsp. cornstarch, 2 cloves garlic, ½ tsp. ginger paste, 2 tsp. rice vinegar, 1 tsp. orange zest, 1 tsp. toasted sesame oil, ½ tsp. salt, 1 tsp. chili sauce
Once reduced, add in the cooked chicken and continue cooking over low heat for a couple of minutes, or until the chicken is heated through.
Serve Orange Chicken over a bed of white rice with green onions and toasted sesame seeds. Enjoy!
