Preheat your oven to 425°F and line a baking sheet with parchment paper.
Pat the chicken breast dry and place it in a shallow bowl.
In a separate bowl, whisk together the egg white, juice from the half orange (reserve the zest from the orange), minced garlic, and grated ginger.
Pour the egg mixture over the chicken, ensuring it is evenly coated.
In another shallow dish, add the panko bread crumbs along with a pinch of salt and pepper.
Dip the chicken in the panko mixture, pressing lightly to ensure an even, crispy coating.
Place the coated chicken on the prepared baking sheet and bake for 20-25 minutes or until the chicken is cooked through and the coating is crisp.
While the chicken bakes, steam the broccoli until tender but still vibrant, about 4-5 minutes.
Once cooked, finish the chicken by sprinkling with the reserved orange zest for an extra burst of citrus aroma.
Plate the crispy orange chicken alongside the steamed broccoli, and serve immediately.
