Combine the basmati rice, coconut milk, water, and salt in a medium saucepan. Stir everything together and bring the mixture to a gentle boil. Reduce the heat to low once boiling. Cover the pan and let the rice cook until tender and fluffy. Allow the rice to rest for a few minutes after cooking. Fluff it gently with a fork before serving.
Pat the chicken breasts dry with paper towels. This helps the seasoning stick more evenly. Rub the jerk seasoning generously over both sides of the chicken. Add a little olive oil to coat the surface. Let the chicken sit for a few minutes while the rice cooks. This allows the flavors to begin absorbing into the meat.
Heat a skillet over medium-high heat and add the olive oil. Once hot, place the seasoned chicken into the pan. Cook until the outside develops a golden, slightly charred crust. Turn the chicken only once for even cooking. Continue cooking until the chicken reaches a safe internal temperature. Remove it from the pan and let it rest before slicing.
Add the diced mango, red onion, cilantro, and lime juice to a mixing bowl. Sprinkle lightly with salt. Gently toss the ingredients together so the mango remains intact. Avoid overmixing. Taste and adjust seasoning if needed. The salsa should taste fresh, sweet, and slightly tangy.
Allow the chicken to rest for several minutes before cutting. This helps retain the juices. Use a sharp knife to slice the chicken into strips. Thin slices work best for serving in bowls. The beautifully seasoned exterior will add plenty of flavor to every bite.
Divide the coconut rice between serving bowls. Spread it evenly across the bottom. Arrange sliced jerk chicken over the rice. Top generously with fresh mango salsa. Add avocado, cilantro, or lime wedges if desired. Serve immediately and enjoy.
