Add the basmati rice, coconut milk, and water to a medium saucepan. Bring to a boil.
Stir once, reduce the heat to low, cover, and cook for 15 minutes until the liquid is absorbed. Remove from heat and let rest for 5 minutes before fluffing.
While the rice cooks, combine the diced mango, chopped red onion, cilantro, salt, and fresh lime juice in a bowl. Mix gently and set aside.
Pat the chicken breasts dry and season both sides generously with jerk seasoning.
Heat the oil in a large skillet over medium-high heat until shimmering.
Place the chicken in the skillet and cook undisturbed for 3–5 minutes.
Flip and cook another 3–5 minutes, or until the internal temperature reaches 165°F (74°C).
Let the chicken rest for a few minutes before slicing.
Assemble the Jerk Chicken Bowls by adding coconut rice to serving bowls, topping with sliced jerk chicken and a generous spoonful of mango salsa. Garnish with an extra lime wedge if desired.
