In a large resealable bag, combine 4 chopped boneless skinless chicken breasts and 4 tablespoons corn starch. Seal the bag and shake it gently until the chicken pieces are well-coated. This step is crucial for achieving a crisp outer layer when cooked.
In a separate bowl, whisk together 6 tablespoons honey, 4 tablespoons ketchup, 3 tablespoons granulated sugar, 1 tablespoon brown sugar, 2 tablespoons white vinegar, 3 tablespoons soy sauce, and 1 teaspoon garlic powder. This sauce will be your flavor bomb, so ensure it’s mixed thoroughly before setting it aside.
Next, heat 2 tablespoons olive oil in a large skillet over medium heat. Once the oil is shimmering, add the coated chicken from the bag. Cook for about 5 to 6 minutes, turning occasionally until the chicken pieces are golden brown and cooked through.
After the chicken is nicely browned, toss in 2 cups broccoli florets. Immediately pour the prepared sauce over the chicken and broccoli. Stir well to coat everyone in that delicious sauce.
Let everything cook for an additional 4 to 5 minutes, continuing to stir occasionally. The broccoli should be vibrant and tender, and the chicken should be fully cooked, reaching an internal temperature of 165 degrees Fahrenheit.
While the chicken and broccoli are cooking, grab a small bowl and mix together 2 tablespoons cornstarch and 2 tablespoons cold water. This mixture is key for thickening your sauce to a perfect consistency.
Once the chicken and broccoli have cooked through, stir in the cornstarch mixture into the skillet. Continue stirring as the sauce thickens, which should take about 1 to 2 minutes. Be sure to watch closely to avoid burning.
Once the sauce has reached your desired thickness, remove the skillet from heat. Finally, sprinkle some sesame seeds over the top as a garnish for a lovely finishing touch.
Serve your delicious Skillet Sesame Chicken Broccoli immediately, either on its own or over cooked rice or noodles for a more filling meal. Enjoy!
