Directions to follow
Prepare the Pickled Scallions: In a heatproof bowl, stir together boiling water, rice vinegar, sugar, mustard seeds, and salt until the sugar dissolves. Toss the sliced scallions to coat and let them rest at room temperature for about 30 minutes.
Rinse the Rice: Under cold water, rinse the jasmine rice until the water runs clear, then drain well.
Cook the Coconut Rice: In a medium saucepan, combine the rice, coconut milk, water, and salt. Bring it to a boil, then cover and reduce the heat to low. Simmer for 15–20 minutes until the liquid is absorbed, and the rice is tender. Fluff with a fork and keep warm.
Preheat the Oven: Set your oven to 425°F (220°C).
Roast the Sea Bass: Place the sea bass fillets on a sheet pan, drizzling with 1 tablespoon olive oil. Season with salt and pepper, then roast for 12–15 minutes until the fish is opaque and flakes easily. Keep warm.
Cook the Vegetables: In a large skillet, heat the remaining olive oil over medium-high. Add onion, garlic, Thai chili, and shiitake mushrooms. Cook, stirring occasionally, for 4–5 minutes until the mushrooms soften and brown.
Make the Miso Coconut Sauce: Stir in the miso paste until smooth, then add coconut cream, rice vinegar, and sugar. Bring to a gentle simmer and cook for 7–8 minutes, stirring often, until the sauce thickens slightly.
Finish with Flavor: Add chili oil, lime zest, and lime juice. Adjust seasoning with salt and black pepper to taste; keep warm over low heat.
Sear the Bok Choy: In another skillet, heat 1 tablespoon of oil over medium-high. Place bok choy cut-side down and cook for 7–8 minutes, turning once until lightly charred and tender. Season with salt and pepper.
Plate Your Creation: Spoon coconut rice onto plates, top with roasted sea bass, and finish with a generous drizzle of the miso coconut sauce. Garnish with pickled scallions, and serve the seared bok choy alongside.

Best ways to enjoy it
Plating this luxurious dish is an art in itself. A small mound of fluffy coconut rice forms a soft bed for the sea bass, while a generous drizzle of miso coconut sauce cascades over the fish, creating a visually stunning centerpiece. Place the bok choy strategically, adding color and crispness to the plate. If you’re feeling fancy, fresh herbs like cilantro or microgreens can lend a vibrant touch.
Pair this feast with a crisp white wine, like a Sauvignon Blanc, or maybe a light sparkling water with lime to cleanse the palate.
How to store & freeze
If you’re lucky enough to have leftovers, store them in an airtight container in the fridge for up to two days. The flavors of the miso coconut sauce deepen as it sits, which can make your next meal even more delicious! Just be sure to store the sauce separately from the fish to keep everything fresh.
To reheat, gently microwave or warm over low heat on the stovetop, adding a splash of coconut milk or water to loosen up the sauce. If you’d like to freeze it, do so before cooking, and defrost in the fridge overnight when you’re ready to use.
Practical cooking tips
- Prep Ahead: You can make the pickled scallions a day in advance, letting their flavors meld beautifully overnight.
- Fish Freshness: Ensure that your sea bass is fresh; it really makes a difference. A firm texture and a clean, briny scent are signs of quality.
- Adjust Spice: Not into spice? Omit the Thai chili or use a milder pepper. You can always add more heat later!
- Cooking Rice: To avoid clumping, stir the coconut rice gently while cooking. Once done, keeping it covered until serving helps maintain its fluffiness.
Creative twists
Feel free to play around! If you want to switch things up, try adding some sautéed bell peppers or snap peas for added crunch to the dish. For a more vibrant stir, consider swapping out the shiitake mushrooms for oyster mushrooms or baby portobellos; their textures lend different dimensions to the dish. And if miso is a bit too bold for your taste, tahini can offer a lovely, nutty flavor in its place.
