Enjoy a dinner as delicious and satisfying as it is healthy and lean. Cooking in individual packages effectively steams the fish and delicate vegetables while retaining all of the flavor and nutrients. This technique is similar to the French en papillote method of baking in parchment, but also has roots in Japanese culinary tradition. Tsutsumi-yaki means cooked package. Feel free to either present these packages for tableside unwrapping or transfer the cooked food to a serving platter and drizzle with the cooking juices.
- 1 leek, julienned
- 1 carrot, julienned
- 2 fish filets, 6 ounces each
- 2 tablespoons sake, divided
- 2 tablespoons mirin, divided
- 2 tablespoon soy sauce or Tamari, divided
- 1 pound brussels sprouts
- 1 tablespoon toasted sesame oil
- 1/2 teaspoon Kosher salt
- 1 tablespoon sesame seeds
- Position oven racks in the upper and lower middle positions. Place a rimmed baking sheet on the lower rack and preheat oven to 450 degrees. Meanwhile, working with 18 by 18-inch square of foil at a time, press foil into bottom of bowl to shape into a bowl. Place shaped foil onto flat work surface.
- Divide leeks and carrots between foil bowls and top with fish fillets. Evenly sprinkle each fillet with 1 tablespoons each of the sake, Kirin, and soy sauce.
- Gently bring the edges of foil together and twist/fold to seal, being sure to leave as much height as possible.
- Toss Brussels sprouts, sesame oil, and salt together in bowl.
- Using oven mitts or dry kitchen towel, remove hot baking sheet from oven. Working quickly arrange Brussels sprouts in a single layer, cut side down and packets on hot sheet tray.
- Return baking sheet to lower rack. Bake until sprouts are well browned and tender and fish registers at least 135 degrees Fahrenheit, about 10-15 minutes.
- To serve, carefully open foil packets. They will release steam, so open away from face!
- Using a spatula, gently place fish and julienned vegetables on plates, reserving liquid.
- Return sprouts to bowl and toss with reserved liquid and sesame seeds.
- Serve immediately alongside fish.
