Weeknight Skirt Steak Sandwiches with Arugula and Herbed Mayonnaise

Here skirt steak, which cooks to medium-rare in five to six minutes total, is layered with arugula between slices of focaccia smeared with herbed mayonnaise. The key, as with all meats, is to let the steak rest for at least 10 minutes before slicing, and with skirt steak, to slice it thinly against the grain.

Ingredients

  • 1 1/4 - 1 1/2 pound skirt steak
  • kosher salt, to taste
  • freshly cracked black pepper, to taste
  • 1/2 cup mayonnaise
  • 1/4 cup finely minced fresh herbs, such as tarragon, parsley, chives, dill, or cilantro
  • 4 4-inch square focaccia or ciabatta rolls, halved
  • 2 ounces arugula

Directions

  1. Preheat the oven to 500°F. Place an Anolon Vesta 12-Inch Cast Iron Skillet in the oven and let it heat for 20 minutes.
  2. Meanwhile, place skirt steak on a cutting board and season generously on both sides with kosher salt and pepper to taste. Halve the steak or cut into thirds to ensure it will fit in the skillet. Stir together the mayonnaise and herbs. Arrange the halved squares of focaccia on a work surface. Spread each half with a thin layer of the herbed mayonnaise.
  3. Carefully remove skillet from the oven and place over high heat. Lower steak into pan and cook undisturbed for 2 to 3 minutes or until nicely browned with edges beginning to cook. Flip, and cook for 2 minutes more. Transfer to a cutting board and let rest for 10 minutes before slicing against the grain into thin strips.
  4. To assemble: Pile 4 to 5 slices steak onto each bottom half of bread. Top with a handful of arugula. Close sandwich and serve immediately.


Use your fan or open your windows. You may want to disable any smoke alarms, too—this technique tends to produce a lot of smoke.


  If time permits, bring steak to room temperature an hour before cooking it.  
  If you can’t find skirt steak, use any other thin (1/2-inch thick or so) piece of meat—thicker cuts of meat will need to be finished at a lower temperature in the oven or over gentler heat stovetop.
