Jalapeño and Lime–Marinated Skirt Steak Tacos

These vibrant jalapeño and lime-marinated skirt steak tacos are a celebration of bright, punchy flavours and tender grilled beef. The marinade, infused with fresh coriander, garlic and earthy cumin, works quickly to tenderise the skirt steak while providing a zesty contrast to the rich meat. Using a griddle pan creates those essential charred edges that bring a professional, smoky finish to your homemade Mexican feast.

As a high-protein dish, these tacos are as nutritious as they are satisfying, making them an excellent choice for a healthy midweek dinner or a relaxed weekend gathering. The combination of creamy avocado, cooling soured cream and sharp lime wedges allows everyone to customise their plate. For the best results, ensure you slice the beef against the grain to guarantee a melt-in-the-mouth texture in every bite.

Ingredients for Jalapeño and Lime–Marinated Skirt Steak Tacos

  • 1 medium jalapeño, thinly sliced

  • 2 garlic cloves, finely chopped

  • 1/4 cup coarsely chopped coriander

  • 1/4 cup fresh lime juice

  • 60ml olive oil

  • 1 teaspoon kosher salt

  • 1/2 teaspoons freshly ground black pepper

  • 3/4 teaspoons ground cumin

  • 450g skirt steak, cut crosswise into 5–6-inch segments

  • 8 (8-inch) corn tortillas

  • Homemade or store-bought tomatillo salsa (for serving)

  • 1/2 medium avocado, sliced

  • 80ml soured cream, thinned with a tablespoon of water or lime juice

  • Crumbled queso fresco (optional), coriander leaves, thinly sliced red onion, and lime wedges (for serving)

Combine jalapeño, garlic, coriander, lime juice, oil, salt, pepper, and cumin in a large resealable bag or bowl. Add steak and toss to coat; if using bowl, wrap with plastic. Marinate at least 30 minutes at room temperature or chill up to overnight in refrigerator, tossing occasionally.

Let steak sit at room temperature 30 minutes before cooking if chilled. Prepare a grill or grill pan for medium-high heat. Remove steak from marinade, scraping off any bits that cling to meat; discard marinade. Grill steak 2–3 minutes per side for medium rare. Let rest 10 minutes before thinly slicing against the grain.

Warm tortillas in a microwave, oven, or over a gas flame. Divide steak among tortillas, then top with salsa, avocado, soured cream, queso fresco, if using, coriander, and onion. Serve with lime wedges alongside.

Steak can be marinated 1 day ahead; keep chilled.
