Ingredients

Grouper fillets (4, about 6 oz each, skin removed): Fresh, firm fillets provide a mild, flaky base that holds up well to rich sauce.
Canned coconut milk (1 cup, full-fat): Adds a creamy, tropical richness essential to the sauce’s silky texture.
Small onion (1, finely diced): Offers subtle sweetness and body, softening gently with the aromatics.
Garlic (2 cloves, minced): Imparts pungent, aromatic depth that complements the spice and coconut.
Fresh ginger (1 tbsp, grated): Adds warm, zesty undertones crucial for balancing richness.
Fresh red chili (1, thinly sliced, seeds optional): Infuses vibrant heat; remove seeds to control spiciness.
Vegetable or coconut oil (1 tbsp): A neutral oil to sauté aromatics and sear the fish beautifully.
Lime juice (juice of 1 lime, about 2 tbsp): Brings bright acidity for freshness and balance.
Brown sugar (1 tsp, packed): Enhances sweetness and rounds out the coconut and chili flavors.
Salt and freshly ground black pepper (to taste): Essential seasoning to enhance all other flavors.
Fresh cilantro leaves (for garnish, roughly chopped): Adds a fresh herbal note and beautiful green contrast.
Optional: Fish sauce (1 tbsp): Provides an extra layer of umami for depth if desired.

Instructions

Prepare Aromatics and Ingredients: Begin by finely dicing the onion, mincing garlic, grating fresh ginger, and thinly slicing the red chili. Setting these out beforehand ensures a smooth cooking process with each ingredient ready to add at the right time.
Heat the Oil and Sauté Aromatics: Warm your vegetable or coconut oil over medium heat in a large skillet until shimmering. Sauté the diced onions for about 3 minutes until softened but not browned, then add garlic, ginger, and red chili. Stir for another minute to release their fragrant oils, building a flavorful base.
Create the Coconut Sauce: Pour in full-fat coconut milk, lime juice, and brown sugar. Gently stir to combine and let the sauce simmer over low heat. Season with salt, pepper, and optional fish sauce to taste. This slow simmer allows flavors to meld beautifully while you cook the fish.
Season and Cook the Grouper: Pat the fillets dry to ensure a good sear, then season both sides lightly with salt and pepper. In a separate pan over medium-high heat, add a little oil and sear the fillets for 3-4 minutes per side, or until opaque and flaky. The goal is a crisp exterior with moist, tender flesh inside.
Combine Fish and Sauce: Transfer the cooked grouper to the coconut sauce pan and let it warm together for a minute or two. This final step helps the fish absorb some sauce flavor. Spoon the creamy sauce generously over the fillets and garnish with chopped fresh cilantro just before serving.

You Must Know

Use fresh, firm grouper for best texture and flavor; avoid frozen if possible.
Adjust chili heat by removing seeds or using less for milder taste.
Shake the coconut milk well before measuring to mix cream and liquid evenly.
Fish sauce is optional but adds authentic umami depth to the sauce.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently on low heat to prevent separating the coconut sauce and to maintain fish texture.

Serving Suggestions

This dish pairs wonderfully with steamed jasmine rice or coconut rice to soak up the sauce. Serve alongside lightly sautéed greens or a tropical mango salsa for a fresh contrast.

Professional Tips

Pat fish dry before searing to achieve a crispy, golden crust.
Sauté aromatics gently to avoid burning and to develop a mellow, balanced base.
