How to Make Thai Coconut Poached Fish

1. Season: Evenly sprinkle kosher salt over the fish fillets, ensuring each piece is well seasoned. Let them sit for a moment to absorb the flavors, enhancing their overall taste.

2. Saut : Heat the neutral cooking oil in a large skillet with a fitted lid over medium heat. Add the thinly sliced onion and cook until softened and translucent, about 5 minutes.

3. Add Aromatics: Stir in the garlic, ginger, and sliced chile, cooking for an additional 2 minutes. You ll know it s ready when the kitchen fills with a fragrant aroma that makes your mouth water.

4. Simmer Broth: Pour in the coconut milk, seafood stock, fish sauce, sugar, and lime zest. Bring the mixture to a gentle simmer, then toss in the fresh spinach. Stir until it wilts and brightens up the broth.

5. Cook Fish: Carefully nestle the seasoned fish fillets into the aromatic coconut broth, ensuring they are mostly submerged. Lower the heat to low, cover, and cook until the fish is just opaque and cooked through, about 6 to 8 minutes.

6. Finish with Lime: Remove the lid and squeeze in some fresh lime juice (start with about 1 tablespoon). Taste and adjust as needed, adding more lime to suit your preference.

7. Garnish and Serve: Plate your Thai Coconut Poached Fish, garnishing with fresh cilantro, scallions, and a drizzle of chili oil or chili crisp for those craving extra spice. Serve over fluffy Jasmine rice to soak up every drop of that delicious broth.
