Description

Flavorful juicy flank steak tacos are quick and simple to prepare. Allow the easy chipotle marinade to season and tenderize the steak before grilling, then slice and tuck the succulent steak into corn tortillas with cabbage slaw and avocados for your next taco night. 


Ingredients

Units Scale
  • 3 chipotle chilis in adobo sauce, minced
  • 1/4 cup plus 2 teaspoons pure maple syrup, dark or amber
  • 5 tablespoons cider vinegar, divided
  • 1 1/2 teaspoons salt, divided
  • 1 small grass-fed flank steak, about 1 1/2 pounds
  • 2 teaspoons canola oil
  • 3 cups finely chopped cabbage
  • 1/2 cup julienne-cut radishes
  • 1/4 cup roughly chopped cilantro leaves
  • 1 avocado, diced
  • 12 corn tortillas, warmed

Instructions

  1. Whisk chipotle, ¼ cup maple syrup, 3 tablespoons vinegar and 1 teaspoon salt in a small bowl. Place flank steak in a large re-sealable plastic bag, and add chipotle mixture. Re-seal and turn to coat. Refrigerate for 12 to 24 hours.
  2. Preheat grill to medium-high heat. Remove steak from the marinade and discard any remaining marinade. Oil grill rack and add flank steak. Grill steak, 5 to 7 minutes per side for medium rare, 6 to 7 for medium and 8 minutes per side for medium-well. Let rest 10 minutes while preparing slaw.
  3. Whisk the remaining 2 teaspoons maple syrup, the remaining 2 tablespoons vinegar, the remaining ½ teaspoon salt and oil in a medium bowl. Add cabbage, radishes and cilantro and toss to combine.
  4. Slice the flank steak into thin strips, across the grain (see tip below). Fill tortillas with steak and slaw and top with avocado.

Notes

How To Slice The Flank Steak:

It is important to cut steak against the grain. The grain is the direction that the muscle fibers run. Cutting across these fibers shortens them and makes the beef slices more tender and easier to chew.

To broil flank steak for tacos:

Arrange oven rack in upper third of the oven. Preheat broiler. Coat a broiler pan with cooking spray. Drain steak, pat dry with paper towels and discard marinade. Place steak on the broiler pan.

Broil the beef just below the heat for 3 minutes. Turn the pan 180 degrees and continue cooking until the meat starts to char in areas.

Flip meat over and cook under the heat, rotating once for an additional 4 to 6 minutes. Let meat rest for at least 5 minutes before slicing against the grain.

To cook flank steak on an indoor grill pan:

Make sure your grill pan is wide enough to accommodate the steak. If it isn’t you can broil it (see above) or pan-sear it in a large skillet. Preheat the grill pan over high heat and set the fume hood on high. Brush oil over the pan.

Remove the steak from the marinade and pat it as dry as possible with clean paper towels. This will help it sear on an indoor grill.

Then place in the pan, and cook until the steak has nice grill marks and easily releases from the pan. This takes about 4-5 minutes on the first side.

Flip over and continue grilling until desired internal temperature (145 F for medium-rare). Remove from the pan, and allow steak to rest on a cutting board for 5-10 minutes before slicing.
