Pineapple Mahi Mahi Recipe Baked: Tropical Citrus Glaze Over Flaky Fish

This baked mahi mahi delivers flaky, tender fish topped with a bright tropical glaze that balances sweet and tangy notes perfectly. The baking method locks in moisture while creating a caramelized finish.

I developed this recipe to highlight mahi mahi’s natural mild flavor without overpowering it. The pineapple citrus glaze enhances the fish’s sweetness while adding a vibrant, restaurant-quality presentation.

You’ll achieve perfectly cooked fillets with a glossy, slightly sticky glaze that pairs beautifully with the fish’s natural texture. The baking process ensures even cooking and a flaky result every time.

Serve alongside rice or roasted vegetables for a complete meal. Here’s how to make this dish.

Ingredients for Pineapple Mahi Mahi Recipe Baked

Bright citrus and pineapple elevate this flaky mahi mahi with minimal effort.

The mahi mahi fillets are the foundation. Wild-caught from a reputable fishmonger or Whole Foods ensures optimal freshness and texture. Look for fillets that are uniform in thickness (about 1-inch) for even cooking. The pineapple juice should be 100% pure without added sugars—brands like Dole or Native Forest are reliable. Fresh citrus juices are non-negotiable; bottled lacks the vibrant acidity needed to balance the glaze.

No pineapple juice? Mango or passionfruit nectar works as a substitute, though the flavor profile shifts slightly. Swap honey for maple syrup or agave if avoiding bee products. Soy sauce can be replaced with tamari for gluten-free or coconut aminos for a milder taste. Fresh ginger is ideal, but ground ginger at one-quarter the amount can be used in a pinch. The cornstarch ensures the glaze clings; omit only if a thinner consistency is acceptable.

Prepare the glaze up to 2 days ahead—store it in the fridge. Mahi mahi is best cooked the same day as purchase, but can be refrigerated for up to 24 hours if necessary. Leftovers keep for 3 days in the fridge, though the fish texture is optimal when fresh. Reheat gently to preserve moisture.

Step-by-Step Instructions for Baked Pineapple Mahi Mahi

Master this technique for perfectly flaky fish with a glossy citrus glaze every time.

Step 1: Prepare the Mahi Mahi Fillets

Pat the 1.5 lb Mahi Mahi Fillets completely dry with paper towels to ensure even browning. Season both sides generously with 0.5 tsp Salt and 0.25 tsp Black Pepper, pressing the seasoning into the flesh so it adheres well.

Place the fillets on a plate and let them sit at room temperature for 10 minutes while you prepare the glaze. This step prevents the fish from seizing up when it hits the hot oven, ensuring it cooks evenly throughout.

Step 2: Create the Tropical Citrus Glaze

In a small saucepan, combine 0.5 cup Pineapple Juice, 2 tbsp Fresh Lime Juice, 2 tbsp Fresh Orange Juice, 2 tbsp Honey, 1 tbsp Soy Sauce, 2 cloves Minced Garlic, and 1 tsp Fresh Ginger. Bring to a gentle simmer over medium heat.

In a small bowl, whisk 1 tsp Cornstarch with 1 tablespoon of cold water to create a slurry. Stir this into the simmering liquid and cook for 2-3 minutes until the glaze thickens enough to coat the back of a spoon. Remove from heat and set aside.

Step 3: Bake the Mahi Mahi to Flaky Perfection

Preheat your oven to 400°F. Lightly grease a baking dish with 1 tbsp Olive Oil, then arrange the seasoned mahi mahi fillets in a single layer. Pour the prepared glaze evenly over the fillets, ensuring they’re fully coated.

Bake for 12-15 minutes until the fish is opaque and flakes easily with a fork. The glaze should bubble and caramelize slightly at the edges. For extra color, broil for the final 1-2 minutes, watching closely to prevent burning.

Step 4: Garnish and Serve Immediately

Sprinkle 0.25 tsp Red Pepper Flakes over the fillets for a subtle kick, if desired. Garnish with 2 tbsp Fresh Cilantro, dividing it evenly across the dish. The cilantro adds a bright, fresh contrast to the rich, sweet-tangy glaze.

Serve immediately while the glaze is still glossy and the fish retains its moisture. The mahi mahi should break apart effortlessly with a fork, revealing tender, flaky layers that soak up the vibrant tropical flavors of the glaze.

Storing and Reheating This pineapple mahi mahi recipe baked

Refrigerator Storage

Let your mahi mahi cool completely, then transfer to an airtight container within 2 hours of cooking. Store in the fridge at 40°F or below for up to 3 days. The flavors meld beautifully overnight, making leftovers even more delicious. ❄️

Freezer Storage

For longer storage, freeze in a single layer first, then transfer to a freezer-safe bag with parchment between fillets. This prevents sticking and preserves the glaze. It keeps well for up to 2 months without texture loss. Always label with the date.

Stovetop Reheating

Gently reheat in a skillet over medium-low heat with 1 tbsp water or broth to prevent drying. Cover and warm for 4-5 minutes, flipping once. This method keeps the fish moist and the glaze glossy.

Microwave Reheating

Place fillets on a microwave-safe plate, cover with a damp paper towel, and heat on 50% power for 1-2 minutes. Check and continue in 30-second bursts until warmed through. The glaze may thin slightly but will re-thicken as it cools.

Oven Reheating

Preheat to 300°F, place fillets in a baking dish with 2 tbsp pineapple juice, and cover with foil. Heat for 10-12 minutes until internal temp reaches 145°F. This method best preserves the original texture.

Serving Leftovers

Reheated mahi mahi works great in tacos or over a cold salad. Add fresh cilantro and lime wedges to brighten the dish. I often serve mine with a side of rice to soak up any extra glaze. 💡
