Grilled Flank Steak with Basil Dressing

For a grilled flank steak with a char-kissed exterior and a perfectly cooked interior, we had to revisit the idea of the marinade. A wet marinade is the enemy of good browning. On top of that, the test kitchen has proven that marinades barely penetrate the surface of meat. But since salt and sugar (when applied far enough in advance) do dissolve and penetrate deep into the meat, we skipped the marinade and simply seasoned our steak with salt, sugar, and pepper.
To cook this wedge-shaped cut to the same internal temperature from end to end, we set up our grill with a cooler side and a hotter side. After briefly grilling the entire steak on the hotter side, we positioned the steak so that the thinner portion was over the cooler side of the grill to save it from overcooking.
Finally, we converted our unused marinade—a vinaigrette of olive oil, basil, lemon, honey, garlic, and pepper—into a sauce that we drizzled over the perfectly grilled steak.

Ingredients

Steak:

  • 1 2-pound flank steak, trimmed
  • 2 teaspoons sugar
  • ½ teaspoon salt
  • ½ teaspoon pepper

Basil Dressing:

  • ¼ cup extra-virgin olive oil
  • ¼ cup chopped fresh basil
  • 1 shallot minced
  • 2 tablespoons red wine vinegar
  • 2 teaspoons lemon juice
  • 1 teaspoon honey
  • 1 clove garlic minced
  • ½ teaspoon red pepper flakes
  • ½ teaspoon salt
  • ¼ teaspoon pepper

Instructions

Pre-season the steak:

  • If using a grill pan, pre-cut the flank steak across the grain in 2-3 large pieces that will fit the surface of your grill pan. Since flank steak has a thicker and a thinner side, be mindful of how you portion the steak so that each portion is relatively consistent in thickness.
  • Pat steak dry with paper towels and sprinkle with sugar, salt, and pepper.
  • Transfer steak to plate, cover with plastic wrap, and refrigerate for at least 1 hour or up to 24 hours.

Prepare the grill:

    For a charcoal grill:

    • Open bottom vent completely. Light large chimney starter mounded with charcoal briquettes (7 quarts). When top coals are partially covered with ash, pour evenly over half of grill. Set cooking grate in place, cover, and open lid vent completely. Heat grill until hot, about 5 minutes.

    For a gas grill:

    • Turn all burners to high, cover, and heat grill until hot, about 15 minutes. Leave primary burner on high and turn off other burner(s).

    Sear, Flip, and Rotate:

      Grill using a charcoal or gas grill:

      • Set wire rack in rimmed baking sheet.
      • Clean and oil cooking grate.
      • Place steak on hotter side of grill and cook (covered if using gas) until browned on both sides, about 2 minutes per side.
      • Flip steak again and rotate so that thin end is over cooler side of grill and thick end remains over hotter side.
      • Continue to cook (covered if using gas), flipping the steak every 2 minutes, until thick end of steak registers 125° (for medium-rare) or 130° (for medium), 2 to 6 minutes longer.
      • Transfer steak to prepared rack, tent with aluminum foil, and let rest for 10 minutes.

      Grill using a grill pan:

      • Set a wire rack in a rimmed baking sheet.
      • Pre-heat the grill pan over medium-high heat for 5 minutes before beginning to grill.
      • Lightly oil the grill pan using tongs and paper towels dipped in canola oil.
      • Place the first piece of steak on the grill pan and cook, covered, until the steak is brown on the first side, about 2 minutes.
      • Flip the steak over and continue to cook, covered, flipping the steak every 2 minutes, until the steak registers 125° (for medium-rare) or 130° (for medium), 2 to 6 minutes longer.
      • Remove the steak to the prepared rack and tent with foil.
      • Repeat with the remaining pieces of flank steak.
      • Let the last piece of steak rest for 10 minutes before serving.

      While the steak is resting, make the dressing:

      • Whisk all ingredients in bowl until well combined; set aside.

      To serve:

      • Transfer steak to carving board and cut in half lengthwise with grain to create 2 narrow steaks.
      • Slice each steak thin on bias against grain.
      • Transfer steak to shallow platter and pour dressing over top. Serve.

      Notes

      • We season this steak with sugar in addition to salt and pepper to help promote browning during the relatively short cooking time.
      • While the original recipe calls for covering the steak with plastic and to avoid patting the steaks dry before grilling, it might make more sense to let the steaks rest in the refrigerator on a rack in a rimmed baking sheet, uncovered, so the steak will dry out and to avoid steaming on the grill pan.
      • The dressing ingredients can be prepared ahead of time and whisked together, except for the basil which should be chopped and whisked in right before serving.
