Flat Iron Steak with Zucchini, Edamame, and Soba Noodles

Scott Phillips

Servings: 6

The deep flavor of flat iron steak works really well with the umami-rich soy sauce and sesame oil featured in this dish. If you can’t find flat iron, substitute rib-eye.


  • Kosher salt
  • 8 oz. dried soba noodles
  • 1 Tbs. Asian sesame oil
  • 3/4 cup soy sauce
  • 3/4 cup mirin
  • 1/4 cup granulated sugar
  • 3 1/4-inch-thick slices peeled fresh ginger
  • 2 medium cloves garlic, peeled
  • 2 flat iron steaks (8 to 10 oz. each)
  • 1 lb. zucchini (2 medium), cut into 2-inch matchsticks
  • 1 12-oz. bag frozen shelled edamame, thawed (about 2 cups)
  • 1 Tbs. chopped pickled ginger (optional)
  • 2 small scallions, white and light-green parts, thinly sliced (optional)
  • 1 Tbs. toasted sesame seeds (optional)

  • Bring a large pot of well-salted water to a boil and cook the noodles until tender, about 4 minutes. Drain well, transfer to a large bowl, toss with the sesame oil, cover, and keep warm.
  • Meanwhile, combine the soy sauce, mirin, sugar, ginger, garlic, and 1 cup water in a 10-inch straight sided sauté pan. Bring to a boil, and then add the steaks. Turn the heat down and simmer gently, flipping once, until medium rare (130°F), 12 to 16 minutes. Transfer the steaks to a cutting board, reserving the liquid in the pan. Discard the garlic and ginger.
  • Return the liquid to a boil. Add the zucchini and edamame, return to a boil, and then lower to a simmer. Cook until the vegetables are just tender, about 2 minutes. Using a slotted spoon, transfer the vegetables to the bowl of noodles. Toss well, cover, and keep warm.
  • Boil the cooking liquid until reduced by half, about 5 minutes.
  • Thinly slice the steaks across the grain. Arrange the noodle mixture on a platter or divide it among 6 shallow bowls. Top with the beef and the pickled ginger, if using. Drizzle some of the sauce over the beef and garnish with the scallions and sesame seeds, if using. Serve, passing the rest of the sauce at the table.

    This recipe is a staple in my repertoire and I’ve tweaked it over the years. I cook the meat as written but I’ve changed the way I do the noodles. Instead of the dry soba noodles, I pick up fresh yaki soba in the cold case at the market. I also chop up a whole bunch of veggies, depending on what’s available — cabbage, carrot, red bell pepper, scallions, bok choy, zucchini, asparagus — and stir fry the veggies with a little garlic and ginger while the meat is resting and the sauce is boiling down. When the veggies are almost done, I add the fresh noodles and a scoop or two of sauce and heat through. Microgreen sprouts are a nice addition after the noodles are off the heat. Plate the noodle/veggie mix, slice the meat and fan on top, sprinkle with sesame, and voila — a one dish meal that never fails to impress!

    Easy to make and tasty! I used lite soy sauce and cut the quantities a bit as I only had a 12oz flat iron.

    I left off the edamame and added red and orange bell peppers instead and my family LOVED this! I will totally incorporate this into my weeknight rotation.
