Step 1: Prepare the Chicken - Begin by cutting the chicken breasts into bite-sized pieces. This helps them cook evenly and quickly.
Step 2: Season and Coat - In a mixing bowl, season the chicken pieces with garlic powder, salt, and pepper. Then, sprinkle the 3 tablespoons of cornstarch over the chicken and toss to coat each piece thoroughly.
Step 3: Heat the Oil - In a large skillet or wok, heat 2 tablespoons of olive oil over medium-high heat. Once hot, add the chicken pieces in a single layer, making sure not to overcrowd the pan.
Step 4: Cook the Chicken - Fry the chicken for about 5-7 minutes or until golden brown and cooked through, turning occasionally for even cooking. Remove the chicken from the skillet and set aside.
Step 5: Make the Sauce - In the same skillet, add the remaining 1 tablespoon of olive oil. Next, add the minced garlic, grated ginger, and optional crushed red pepper flakes. Sauté for about 30 seconds until fragrant.
Step 6: Combine Ingredients - Pour in the brown sugar, water, and low sodium soy sauce. Stir well to dissolve the sugar and bring the mixture to a simmer.
Step 7: Thicken the Sauce - In a small bowl, mix 1 tablespoon of cornstarch with a splash of water to create a slurry. Add this to the sauce in the skillet, stirring constantly until the sauce thickens, about 1-2 minutes.
Step 8: Add the Chicken - Return the cooked chicken to the skillet and toss well to coat in the sauce. Add the chopped scallions and stir for another minute until heated through.
Step 9: Serve - Remove from heat and serve your Easy Mongolian Chicken over rice or noodles, garnished with additional scallions if desired.
