Yucatecan -Style Grilled Mahi-Mahi

This vibrant Yucatecan-style grilled mahi-mahi brings the sunshine of the Mexican peninsula to your dinner table. The firm, lean white fish is steeped in a fragrant marinade of earthy achiote paste, citrus juices, and aromatic oregano before being gently steamed inside banana leaves. This traditional cooking method ensures the fillets remain incredibly succulent while absorbing the subtle, smoky notes from the grill, resulting in a dish that is as visually impressive as it is delicious.

As a diabetes-friendly main course, this recipe focuses on high-quality protein and heart-healthy fats, making it a nutritious choice for a light summer supper. Serving the fish with sharp pickled onions and a fresh tomato salsa adds a wonderful brightness without the need for heavy sauces. It is an excellent option for those seeking a sophisticated yet simple homemade meal that is naturally low in carbohydrates and bursting with fresh, authentic flavour.

How to make Yucatecan -Style Grilled Mahi-Mahi

Place fish in 13x9x2-inch glass baking dish. Whisk achiote paste and next 7 ingredients in medium bowl. Pour achiote mixture over fish; turn to coat. Cover and chill 1 hour.

Prepare barbecue (high heat). Brush shiny side of banana leaves with 2 tablespoons oil; place each on baking sheet, oiled side down (some of leaf will hang over edge of sheet). Arrange 2 fillets with marinade still clinging crosswise in centre of each banana leaf, spacing 2 inches apart. Drizzle wine around fish in leaves. Top each fillet with 1 bay leaf and 1 sprig of fresh epazote or parsley or 1 pinch of dried epazote. Fold overhanging edges of banana leaf over fish to enclose loosely. Transfer fish from baking sheet to grill, folded edges up. Cover and grill until fillets are just opaque in centre, about 10 minutes.

Open banana leaves. Transfer fish to plates. Garnish with tomato and lime slices. Serve with Yucatecan Pickled Onions and Habanero-Tomato Salsa.
