Start by preheating your oven to 400°F (200°C). This temperature helps the coconut crust cook quickly and turn golden brown. Line a baking sheet with parchment paper so the fish won’t stick while baking.
In a shallow plate, combine breadcrumbs, shredded coconut, salt, cumin, paprika, garlic powder, and black pepper. Mix everything thoroughly so the spices distribute evenly. This mixture will create the crispy, flavorful coating on the fish.
Crack the egg into a bowl and whisk until smooth. Dip each fish fillet into the egg mixture, making sure it is fully coated. Then press the fish into the coconut breadcrumb mixture so both sides are evenly covered.
Place each coated fillet onto the prepared baking sheet. Leave a little space between them so they cook evenly. Lightly drizzle olive oil over the top of each fillet to help the crust crisp up during baking.
Transfer the baking sheet to the oven and bake for about 15 minutes. The fish should turn golden brown on the outside and flaky on the inside. Cooking time may vary depending on the thickness of your fillets.
While the fish is baking, combine diced mango, cherry tomatoes, diced purple onion, jalapeño, lime juice, salt, and chopped cilantro in a bowl. Toss everything together gently so the ingredients stay fresh and vibrant.
Once the fish is cooked, remove it from the oven and let it rest for a minute. Spoon the fresh mango salsa over each fillet just before serving. The cool salsa balances the warm crispy fish perfectly.
