Because flat-iron steaks are well marbled, there's no need to add oil to the skillet. When cooked up to medium, they remain tender and juicy. Our stir-together mustard sauce is another delicious accompaniment.

Instructions Checklist
  • Heat a large cast-iron or other heavy-bottomed skillet over medium-high until very hot. Season steaks with salt and pepper. Add to skillet; sear 4 to 8 minutes per side for medium-rare (if browning too quickly, reduce heat after turning steaks). Transfer steaks to a plate, and cover loosely with aluminum foil (reserve skillet).

  • Add wine to skillet; simmer over medium-high, stirring occasionally and scraping up browned bits with a wooden spoon, until syrupy, 4 to 6 minutes. Remove skillet from heat. Stirring constantly, drop butter into sauce, one piece at a time, waiting for each piece to blend in before adding the next. Season with salt and pepper. Serve steaks drizzled with sauce.

I added some shallot, which I love with beef, to the wine before reducing slightly. I sprinkled some freshly minced chives on top before serving. Fabulous!

Very delicious. I did the wine reduction, and would not do it again. It added no additional flavor. The mustard sauce is a must! Simple, easy, and fast dinner.
