The Key Ingredients (and Why They Matter)

Below I list the main components (no amounts here — follow the recipe card). I’ll explain what each does so you can tweak with confidence.

• Mahi-Mahi fillets — Firm white flesh holds the crust; mild taste pairs well with sweet-savory sauces. Fresh is great; frozen works fine.
• Toasted shredded coconut — Offers the characteristic island flavor and crunchy exterior. Toast it for deeper, nuttier notes.
• Panko breadcrumbs — Light and airy; they build crunch without turning heavy.
• Flour + egg wash — Create the “glue” that helps the coconut-panko stick to the fish.
• Butter — For both browning the fillets and finishing the sauce — butter makes everything feel indulgent.
• Pineapple juice + beer — The acid and sweetness from pineapple cut through the butter, while beer adds a mellow, malty depth.
• Salt, white pepper, coriander — Minimal seasonings that highlight, not hide, the fish. Use them sparingly.

If you swap anything, keep the balance: crunchy exterior, tender fish, and a bright sauce to tie it together.

How to Make It

Prep the fish

Dry the fillets well. Pat them until they stop looking damp. Season with salt, white pepper, and ground coriander. Let them rest on a rack in the fridge for 15–30 minutes — this firms the surface and helps the coating stick.

Build the breading station

Set out three shallow bowls: one with flour, one with beaten eggs (thin with a splash of cold water), and one with the coconut-panko mix. Press the coconut mixture gently into the fish so it adheres well.

Pan-sear, then finish in the oven

Heat an oven-safe nonstick skillet over medium-high and melt a few tablespoons of butter. Sear the coated fillets 2–2½ minutes per side until the crust darkens but doesn’t burn. Slide the whole pan into a preheated 425°F oven and roast about 10 minutes, or until the fish flakes easily.

Make the Pineapple Beer Butter Sauce

Reduce pineapple juice and beer over medium heat until nearly dry. Remove pan from heat and whisk in cold butter one tablespoon at a time until emulsified and glossy. Don’t rush this — adding butter too fast or heating too high will break the sauce. Season with a little salt and taste.

Serve

Plate the fish, drizzle the sauce tableside, and garnish with cilantro leaves or microgreens. Serve immediately.

Pro tips for perfect results

• Dry the fillets thoroughly. Moisture prevents a crispy crust.
• Toast your coconut. Toasting enhances flavor and prevents sogginess.
• Don’t crowd the pan. Overcrowding drops the pan temperature and ruins the sear.
• Add butter slowly to the sauce and keep heat low — temps above 135°F can cause it to break.
• Use an oven-safe skillet. Sear on the stovetop, then finish in the oven for even cooking.
• Test doneness by flaking. The fish should flake easily with two forks.

Bold tip: If you’re unsure about searing time, a quick internal temp target of 135–140°F will keep the fish juicy without overcooking.

Why cookware matters (and a quick equipment note)

A good nonstick, oven-safe pan helps the coconut crust slide off—onto the fish, not the skillet. We like using reliable nonstick cookware that tolerates metal tools and high oven heat. If you’re in the market for new pans, consider brands known for durability and oven safety. (FYI: a sturdy pan saves you cleanup grief and helps you get that perfect crust.)

Variations to try

• Spicy glaze: Add a tablespoon of sriracha or a chipotle puree to the sauce for a smoky kick.
• Nutty twist: Mix finely chopped macadamia nuts into the coconut for extra crunch.
• Citrus finish: Add a squeeze of lime or a splash of orange juice to the sauce for zesty brightness.
• Herb crust: Stir chopped cilantro and parsley into the coconut-panko for a fresher herbaceous note.
• Beer swap: Use a lighter lager for a cleaner finish, or a wheat beer for more citrusy highlights.

Don’t be afraid to experiment — this recipe forgives small changes and often rewards them.

Best ways to serve this (Caribbean-style favorites)

• Pigeon peas & rice — A traditional pairing that soaks up the sauce beautifully.
• Fried plantains — Sweet, caramelized, and texturally perfect alongside the fish.
• Simple green salad — A crisp counterpoint to the buttery sauce.
• Coconut rice — If you love coconut, double down for a truly tropical plate.

This makes a standout Caribbean Fish Dinner when you add those sides. Serve family-style or plate individually for a fancier presentation.

Quick tips for storage and leftovers

• Cooked fish: Store in an airtight container in the fridge for up to 2 days. Reheat gently in a 300°F oven to avoid drying.
• Sauce: Refrigerate separately for up to 3 days. Rewarm over very low heat, whisking to re-emulsify.
• Coconut crust: It loses crunch when refrigerated on the fish — store any extra crust in a separate airtight container at room temp.
  IMO, this dish tastes best fresh, but leftovers still make a terrific fish taco filling.

A note on flavor balance

This recipe walks a tightrope between sweet and savory. The coconut and pineapple add gentle sweetness; the beer brings depth and a touch of bitterness; the butter adds silk. Keep seasonings light and taste as you go. The fish should remain the star.
