Start by whisking together the honey, soy sauce, and chili garlic sauce in a small bowl. This mixture is the heart of the dish, delivering sweet and savory flavors. Set it aside so it’s ready to go later.
Cut the chicken thighs into bite-sized pieces, then toss them with salt, garlic powder, black pepper, and cornstarch in a medium bowl. The cornstarch helps create a slight crust on the chicken, which absorbs the sauce beautifully.
Heat 1 tablespoon of butter in your skillet over medium-high heat. Toss in the zucchini, bell pepper, and onion, and cook until the veggies are tender yet slightly charred. This step adds smoky undertones to the dish. Transfer them to a plate and set them aside.
Using the same skillet, add the remaining butter and sesame oil. Cook the seasoned chicken until it’s golden brown, crispy on the outside, and fully cooked through. Add the minced garlic and ginger, letting them sauté for a few seconds until fragrant. This step builds the flavor with aromatic notes.
Pour the prepared sauce over the chicken, bringing it to a boil. Stir frequently until the sauce thickens to a glossy consistency and coats the pieces fully. Return the cooked vegetables to the skillet, tossing everything together for a flavorful finish.
