In this post, we’ll guide you through preparing Mahi Mahi in banana leaves, showcasing the vibrant flavors of Costa Rica.

The Essence of Costa Rican Cuisine

Costa Rican cuisine is a captivating mix of indigenous, Spanish, and Afro-Caribbean influences. It boasts fresh ingredients, colorful flavors, and diverse cooking methods. Essential components of Costa Rican cooking include herbs, spices, and local produce, which create hearty and delicious dishes.

For Mahi Mahi, embrace local favorites like garlic, cilantro, lime, and chili peppers. These ingredients are commonly used and can truly elevate your meal.

Ingredients You'll Need

Gather these ingredients to create your delicious Mahi Mahi dish:

4 Mahi Mahi fillets
4 large banana leaves (fresh or frozen)
2 tablespoons olive oil
4 cloves garlic, minced
1 small onion, finely chopped
1 red bell pepper, diced
1 green bell pepper, diced
1 lime (juice and zest)
1 teaspoon ground cumin
1 teaspoon paprika
1 teaspoon salt
1/2 teaspoon black pepper
Fresh cilantro for garnish

Preparing the Ingredients

Preparation is key to a great dish. Here’s what you need to do:

Banana Leaves: If using frozen leaves, thaw them and clean. Rinse fresh leaves under cold water. Cut them into squares roughly 12 inches by 12 inches to wrap the fish.
Mahi Mahi: Rinse the fillets under cold water and pat dry with paper towels, ensuring they're clean for optimal flavor absorption.
Vegetables: Chop the onion and bell peppers, and mince the garlic.
Seasoning: Mix olive oil, lime juice, lime zest, cumin, paprika, salt, and black pepper to create a flavorful marinade.

Marinating the Mahi Mahi

Now that your ingredients are ready, marinate the Mahi Mahi for enhanced flavor:

Place the fillets in a shallow dish and pour the marinade over, making sure they’re evenly coated.
Cover the dish with plastic wrap and refrigerate for at least 30 minutes. This marination time allows the ingredients to meld and enhances the fish’s natural flavor.

Assembling the Dish

With the Mahi Mahi marinated, it’s time to assemble the dish using the banana leaves:

Lay a banana leaf on a clean surface, shiny side up.
Place a marinated Mahi Mahi fillet in the center.
Add a spoonful of the chopped onion and bell peppers on top of the fish.
Fold the banana leaf over the fish and vegetables, sealing it tightly. Use kitchen twine or toothpicks to secure it if necessary.
Repeat this process for the remaining fillets.

Cooking the Mahi Mahi

You can cook your banana leaf-wrapped Mahi Mahi through different methods, such as grilling, baking, or steaming. Here’s how to use each method:

Grilling

Preheat your grill to medium-high heat.
Place the wrapped Mahi Mahi directly on the grill grates.
Grill for about 10-15 minutes, turning occasionally. The fish should be cooked through and flake easily.

Baking

Preheat your oven to 375°F (190°C).
Place the wrapped Mahi Mahi on a baking sheet.
Bake for 20-25 minutes, or until the fish reaches the right texture.

Steaming

Fill a large pot with water and bring to a boil.
Place a steaming rack in the pot and arrange the wrapped Mahi Mahi on top.
Cover the pot and steam for about 15-20 minutes until cooked through.

Serving Suggestions

Once your Mahi Mahi is ready, it’s time to serve:

Carefully unwrap the banana leaves to let the steam escape.
Transfer the fish and vegetables to a serving platter.
Garnish with fresh cilantro and lime wedges to add a burst of flavor.
Pair with traditional Costa Rican sides like rice and beans or a refreshing salad for a complete meal.
