Ingredients You’ll Need

Tip: You’ll find the full list of ingredients and measurements in the recipe card below.

120 ml chopped fresh mango
120 ml white wine
25 g sugar
1 teaspoon peeled and minced fresh ginger
Juice of 2 fresh limes
60 ml heavy cream
115 g unsalted butter, cut into small pieces
Salt and ground black pepper, to taste
6 Mahi Mahi fillets (170 g each, approximately 1.02 kg total)
30 ml olive oil
½ teaspoon Italian seasoning (optional)

Let’s Get Started

In a small saucepan over medium heat, combine the chopped mango, white wine, sugar, and minced ginger. Bring to a gentle simmer and cook for 5–7 minutes until the mango softens and the liquid reduces slightly.
Stir in the fresh lime juice and continue simmering for another 2–3 minutes. The mixture should smell bright and slightly citrusy.
Lower the heat and stir in the heavy cream. Let it gently simmer for 2 minutes, stirring occasionally.
Reduce heat to low and begin adding the butter pieces a few at a time, whisking constantly. Allow each piece to melt fully before adding the next. The sauce should become smooth, glossy, and slightly thickened.
Season the sauce with salt and black pepper to taste. For a smoother texture, you may blend the sauce briefly, then return it to low heat to keep warm. Do not let it boil once the butter is incorporated.
Pat the mahi mahi fillets dry with paper towels. Season both sides with salt, pepper, and Italian seasoning if using.
Heat olive oil in a large skillet over medium-high heat. Once hot, add the fillets and cook for about 3–4 minutes per side, depending on thickness. The fish should be opaque and flake easily with a fork when done.
Remove the fish from the skillet and let it rest for 2–3 minutes. Spoon the warm mango lime butter generously over each fillet before serving.

Servings and Pairing

This recipe serves 6. Pair with coconut rice, roasted asparagus, or a light cucumber salad. It’s also beautiful served alongside grilled vegetables or a simple mixed greens salad with a citrus vinaigrette.

Variations

Add a pinch of red pepper flakes to the sauce for gentle heat.
Substitute pineapple for mango for a slightly tangier twist.
Grill the mahi mahi instead of pan-searing for a smoky flavor.
Add fresh chopped cilantro to the sauce for a herbal finish.

Storage Tips

Store leftover fish and sauce separately in airtight containers in the refrigerator for up to 2 days. Reheat gently over low heat. Avoid high heat to prevent the butter sauce from separating.

FAQs

Can I use frozen mahi mahi?

Yes. Thaw completely in the refrigerator and pat dry before cooking for best texture.

How do I know when the fish is done?

The fish should turn opaque and flake easily with a fork. Internal temperature should reach 63°C.

Can I make the sauce ahead of time?

You can prepare the reduction in advance, but whisk in the butter just before serving for the best texture.

Final Thoughts

Mahi Mahi with Mango Lime Butter is fresh, flavorful, and beautifully balanced. The silky butter sauce with bright citrus and sweet mango transforms simple fish into something truly special. It’s a dish that feels impressive but is wonderfully approachable to make at home.
