Pat chicken breasts completely dry with paper towels—moisture is the enemy of crispiness. Slice each breast horizontally to create two thin cutlets of uniform thickness, ensuring even cooking throughout the 20-minute process.
Combine flour, salt, pepper, and cornstarch in a shallow bowl with precision. Whisk eggs in a separate bowl until completely uniform, then set both stations up for quick breading work.
Dredge each chicken piece in flour mixture, shaking off excess, then dip into egg wash, then back into flour for a double-coated, extra-crispy crust. Work quickly so the coating doesn't become soggy from residual moisture.
Heat vegetable oil in a large skillet over medium-high heat until shimmering but not smoking, approximately 2 minutes. This crispy honey garlic chicken elegant recipe depends on proper oil temperature—too hot burns the outside, too cool produces grease instead of crust.
Fry chicken pieces 3-4 minutes per side until deeply golden and internal temperature reaches 165°F, using an instant-read thermometer for precision. Transfer to a paper towel–lined plate immediately after cooking.
In the same skillet, reduce heat to medium and add minced garlic to the remaining oil, stirring constantly for 30 seconds until fragrant. Add honey, soy sauce, rice vinegar, and chicken broth, whisking until completely combined.
Mix cornstarch with 1 tablespoon water to create a slurry, then pour into the sauce while stirring constantly for 60 seconds until it thickens into a glossy coating. The glaze should coat the back of a spoon but still flow easily.
Return chicken to the skillet and toss gently to coat every surface with the stunning glaze. Cook for 1-2 minutes until the coating becomes tacky and caramelizes slightly, then drizzle sesame oil over everything and garnish with green onions.
