Ingredients

Scale
  • 1.5 pounds flank steak, trimmed of excess fat
  • 1 cup beer (preferably darker lager or amber ale)
  • 2 tablespoons olive oil
  • Juice of 1 large lime (about 2 tablespoons)
  • 3 cloves garlic, minced
  • 1 teaspoon ground cumin
  • 1 teaspoon chili powder
  • 1 teaspoon paprika
  • 1 teaspoon salt (kosher preferred)
  • ½ teaspoon freshly ground black pepper
  • 1 large onion, sliced into thin strips
  • 2 medium bell peppers (red and green), sliced into strips
  • 810 flour or corn tortillas, warmed
  • Optional toppings: fresh cilantro, sliced avocado, sour cream, shredded cheese, lime wedges

Instructions

  1. Prepare the marinade by whisking together beer, olive oil, lime juice, minced garlic, cumin, chili powder, paprika, salt, and black pepper in a large mixing bowl.
  2. Place the flank steak into the marinade, turning to coat all sides. Cover and refrigerate for a minimum of 2 hours, ideally 4-6 hours or up to overnight.
  3. About 15 minutes before grilling, slice the onion and bell peppers into thin strips. Toss lightly with a pinch of salt and a drizzle of olive oil.
  4. Preheat the grill to medium-high heat (about 450°F). If using a grill pan, preheat over medium-high heat until smoking slightly.
  5. Remove the steak from the marinade, letting excess drip off and discard the marinade. Grill the steak for 3-4 minutes per side for medium-rare (internal temperature about 130°F). Avoid flipping too often.
  6. While the steak rests under foil for 5 minutes, grill the onions and peppers, turning occasionally until tender and slightly charred (8-10 minutes).
  7. Slice the steak thinly against the grain into strips.
  8. Warm the tortillas on the grill for 30-60 seconds per side. Assemble fajitas by filling tortillas with steak strips, grilled vegetables, and desired toppings.

Notes

Marinate steak at least 2 hours for tenderizing; 4-6 hours is ideal. Slice steak against the grain for tenderness. Let steak rest under foil after grilling to redistribute juices. Use direct high heat for searing to lock in flavor. For gluten-free, use corn tortillas and gluten-free beer. For dairy-free, omit cheese and sour cream or use alternatives.
