Pat the mahi mahi dry and season both sides with paprika, garlic powder, onion powder, salt, and pepper. Heat olive oil in a skillet over medium-high heat and sear the fillets 3–4 minutes per side until golden and flaky.
Lower the heat and add butter to the same pan. Once melted, stir in lime zest, lime juice, and honey. Let it gently bubble into a glossy sauce.
Fold in diced mango and let it warm slightly without overcooking.
Return the fish fully into the pan and spoon that buttery mango lime sauce generously over the top. Sprinkle chopped parsley or cilantro for a fresh finish.
Plate the mahi mahi and spoon extra mango lime butter over each fillet. Garnish with more mango cubes and herbs. Serve immediately.
