01 - Preheat oven to 400°F (200°C). Lightly grease a baking dish large enough to fit the chicken breasts in one layer.
02 - In a blender or food processor, combine diced mango, sweet chili sauce, lime juice, honey, minced garlic, soy sauce, fresh ginger, and chili flakes. Blend until completely smooth.
03 - Sprinkle chicken breasts with salt and freshly ground black pepper. Arrange them in the prepared baking dish.
04 - Pour the mango sweet chili sauce over each chicken breast, ensuring an even coating.
05 - Transfer dish to preheated oven. Bake for 25–30 minutes until chicken is thoroughly cooked and sauce is bubbling. Broil for 2–3 minutes at the end for a caramelized finish, if desired.
06 - Remove from oven and let rest for 5 minutes. Top with chopped cilantro, sliced red chili, and lime wedges before serving.
