Ingredients You’ll Need
🐟 For the Fish:

- Salt and freshly ground black pepper, to taste
- Juice of 1 lime
- 1 tablespoon neutral oil (vegetable, coconut, or avocado)
🥥 For the Sauce:
- 1 tablespoon oil (if not reusing the fish pan)
- 2 cloves garlic, minced
- 1-inch piece fresh ginger, grated
- 1 small shallot or ½ red onion, finely chopped
- 1 small red chili (optional), thinly sliced
- 1 cup full-fat coconut milk
- 1 tablespoon fish sauce (or soy sauce for vegetarian)
- Zest of 1 lime
- Juice of 1 lime
- 1 teaspoon brown sugar or palm sugar
- Optional: 1 torn kaffir lime leaf
- Fresh cilantro and Thai basil for garnish
🍚 Suggested Sides:
- Steamed jasmine or basmati rice
- Stir-fried greens (bok choy, spinach, or morning glory)
- Pickled carrots or cucumber salad for a refreshing contrast
Kitchen Equipment Needed
To make this recipe, you’ll need:
- Sharp knife and cutting board
- Citrus juicer or reamer
- Grater or microplane (for ginger and lime zest)
- Skillet or nonstick frying pan with lid
- Spatula or fish turner
- Measuring spoons
- Mixing bowl (for marinating fish)
- Small whisk or spoon (for stirring sauce)
Step-by-Step Instructions
1. Marinate the Fish
Start by patting your fish fillets dry to help them sear properly. Season with salt, pepper, and the juice of one lime. Let them marinate for 10–15 minutes while you prep your sauce ingredients. This simple step brightens the fish and infuses it with tangy flavor.
2. Sear the Fish (Optional but Recommended)
Heat oil in a skillet over medium heat. Sear the fish fillets for 2–3 minutes on each side until lightly golden. Don’t worry if they aren’t fully cooked—they’ll finish poaching in the sauce later. Remove from the pan and set aside.
3. Sauté Aromatics
In the same pan (add more oil if needed), sauté minced garlic, ginger, and shallot for about 1–2 minutes until fragrant. Add chili and kaffir lime leaf if using. This step builds the foundation of your flavor-packed sauce.
4. Make the Coconut Lime Sauce
Pour in the coconut milk and bring to a gentle simmer. Stir in fish sauce, sugar, lime zest, and fresh lime juice. The goal here is balance—taste and adjust as needed. You’re looking for a creamy, tangy, savory sauce with just a hint of sweetness.
5. Poach the Fish
Gently nestle the fish fillets into the simmering sauce. Cover and cook for 5–7 minutes, or until the fish flakes easily with a fork. Don’t overcook—white fish is delicate!
6. To Serve
Plate the fish over a bed of jasmine rice, spoon the coconut lime sauce generously on top, and garnish with cilantro, Thai basil, and chili slices. Add a lime wedge on the side for extra brightness.
Tips, Shortcuts, and Swaps
- Short on time? Skip the marinating and go straight to the searing step, adding lime juice directly to the sauce instead.
- For more heat, stir in a teaspoon of Thai red curry paste when sautéing the aromatics.
- For added veggies, toss in spinach, snap peas, or bell peppers in the last 3–4 minutes of poaching.
- Want it crispy? Dredge the fish in cornstarch and shallow-fry until golden, then spoon the sauce over just before serving.
- Going vegetarian or vegan? Use tofu, tempeh, or mushrooms in place of fish and soy sauce instead of fish sauce.
Food & Drink Pairings
Side Dish Pairings:
- Steamed jasmine rice is a must for soaking up the luscious coconut lime sauce.
- Quick-pickled cucumber or carrots add a crisp, cooling contrast.
- Stir-fried bok choy or Chinese broccoli balances richness with earthy greens.
Drink Pairings:
- A Thai iced tea or coconut water will enhance the tropical notes.
- For wine lovers, a Riesling or Sauvignon Blanc offers citrusy freshness that complements the dish’s acidity.
- Sparkling water with lime keeps things light and refreshing.
How to Store Leftovers
Got leftovers? Here’s how to keep that creamy goodness just right:
- Storage: Place cooled fish and sauce in an airtight container. Refrigerate for up to 2 days.
- Reheating: Gently warm on the stovetop over low heat, stirring occasionally. Avoid boiling, as it may cause the coconut milk to separate.
- Freezing: Not recommended. The texture of the fish and coconut milk sauce doesn’t hold up well to freezing.
Frequently Asked Questions (FAQ)
Q: Can I make this dish ahead of time?
A: You can prep the sauce a day in advance, but it’s best to cook the fish just before serving to preserve its delicate texture.
Q: What kind of fish works best?
A: Mild, firm white fish like cod, halibut, snapper, or tilapia are ideal. Avoid overly flaky fish like haddock or thin fillets that may overcook quickly.

A: Skip the rice and serve with stir-fried greens, zucchini noodles, or cauliflower rice instead.
Q: Is this recipe gluten-free?
A: Yes, as long as your fish sauce or soy sauce is certified gluten-free.
Q: What if I can’t find Thai basil?
A: Substitute with regular basil or even fresh mint for a different twist.
