Turbot with Mushrooms, Ginger, and Soy Broth comes together quickly and makes for an easy, healthy, and flavorful main course. Serve this brothy, umami-rich dish with steamed rice and sautéed baby bok chop or another leafy Asian green. If you can't find turbot (a delicate, flat white fish), substitute with another delicate, flaky white fish. Most options should work, but be sure to watch cook time carefully as it may need to be adjusted.
Preheat the oven to 425°F (220°C) with a rack in the center position.
Thinly slice the mushrooms and spread them out in a large 9 x 13 inch (23 x 33 cm) baking dish (they should fill and reach ¾ up the sides of the dish). Add 4 tablespoons of the finely minced ginger, the minced garlic, toasted sesame oil, and soy sauce to the dish and gently toss everything together. Season with salt and pepper.
Roast for 15 minutes, tossing once or twice, until the mushrooms are soft and the juices have released. Remove from the oven and season with salt and pepper to taste.
Slice the fish into 4 ounce pieces and season generously with salt and pepper. Rub the tops of the fish with the remaining minced ginger (dividing it evenly among all the pieces). Place the fish on top of the cooked mushrooms, spacing them apart by an inch or so, and bake for another 8 to 12 minutes (depending on the thickness of your fish fillets), or until the fish is just cooked and flakes easily with a fork.
Serve immediately with steamed rice and sauteed baby bok choy or another leafy green.
Tips for Success:
If you are unable to find turbot fillets at your local grocery store or fish monger, feel free to substitute with flounder or another delicate, flaky white fish.
