Slice the chicken breasts in half so that they have the same thickness. If you don't cut them to the same thickness, they will cook differently.

In a small bowl, mix the orange juice, soy sauce, hoisin sauce, ginger, garlic, sugar and salt.

In a glass casserole, add the chicken breasts, pour 2 tbsp of the sauce on top, and mix the breasts lightly. Cover with a plastic film and refrigerate for an hour (up to 24 hours). Keep the remaining sauce in the refrigerator as well. By marinating the chicken breasts, the sauce adds flavor to the meat and will become more tender after cooking.

Preheat the oven to 375°F. Drain the marinated chicken breasts and arrange them on a casserole or a deep tray. Pour the reserved sauce over the chicken and bake for about 30-35 minutes, turning the chicken breasts twice during baking.

Remove the chicken breasts from the oven and let them cool for 5 minutes.

Serve with sesame seeds and chopped chives on top, along with a side dish such as rice, broccoli, asparagus, or anything else you prefer.

Enjoy the meal!
