Flank steak fajitas made with a beer-lime marinade is tender and so flavorful. Sautéed onions and colorful strips of bell pepper are stuffed into flour tortillas and topped with sour cream, cheese and salsa.
Combine the beer, half the cilantro, lime juice, oil, chipotle peppers, garlic, honey, cumin, salt, and pepper in a blender or food processor. Blend until everything is finely chopped and well mixed. Pour the marinade over the steak in a shallow dish, cover, and refrigerate for at least 4 hours, turning the meat occasionally.
Preheat the broiler for 5 minutes. Remove the steak from the marinade and pat it dry with paper towels. Brush both sides lightly with olive oil and place it on a baking sheet.
Position the sheet pan on the upper rack, about 4 inches from the broiler. Broil for 6–8 minutes, then flip and broil for another 4–6 minutes for medium-rare. For medium to well-done, add 2 to 4 more minutes. Transfer the steak to a cutting board, cover loosely, and let it rest while you cook the vegetables.
Heat the oil in a large skillet over medium-high heat. Add the onion and cook for about 1 minute, then add the sliced peppers. Cook until the vegetables are tender but still crisp. Stir in the remaining ½ cup of cilantro and toss to combine. Transfer the vegetables to a serving platter. Slice the flank steak thinly against the grain and arrange it alongside the peppers.
Serve with warm tortillas, lime wedges, sour cream, salsa, Cotija cheese and cilantro sprigs.
Notes
Marinate ahead: Let the steak sit in the marinade for at least 4 hours, or overnight, for maximum flavor. It’s an easy make-ahead move that pays off.Prep the steak: Pat the steak dry so it sears properly under the broiler.Slice it right: Cut against the grain to keep the steak tender.Don’t crowd the pan: Give the veggies space in the skillet so they sear instead of steam. Work in batches if needed to keep them crisp and caramelized.Warm the tortillas: Heating them up makes them soft, pliable, and easier to fold.Nutrition values do not include the marinade or optional add-in items.
