📝 About This Recipe

This recipe elevates the humble skirt steak into a gourmet low-carb masterpiece by pairing its deep, beefy intensity with a vibrant, herbaceous Italian-style salsa verde. The steak is seared to a perfect medium-rare crust, while the sauce—a punchy blend of fresh parsley, capers, and lemon—cuts through the richness of the fat beautifully. It is a quintessential keto meal that feels incredibly indulgent without the need for heavy starches or sugars.

🥗 Ingredients

The Steak

  • 2 lbs Skirt Steak (outside skirt preferred, trimmed of excess silver skin)
  • 2 tablespoons Avocado Oil (or any high-smoke point oil)
  • 1.5 teaspoons Kosher Salt (to taste)
  • 1 teaspoon Black Pepper (freshly cracked)
  • 1/2 teaspoon Garlic Powder

The Salsa Verde

  • 2 cups Fresh Flat-Leaf Parsley (packed leaves, finely chopped)
  • 1/2 cup Extra Virgin Olive Oil (high quality)
  • 2 tablespoons Capers (drained and minced)
  • 2 pieces Anchovy Fillets (finely mashed into a paste)
  • 2 cloves Garlic (grated or microplaned)
  • 1 tablespoon Lemon Juice (freshly squeezed)
  • 1 teaspoon Lemon Zest
  • 1/4 teaspoon Red Pepper Flakes (optional for heat)
  • 1 teaspoon Red Wine Vinegar

👨‍🍳 Instructions

  1. 1

    Remove the skirt steak from the refrigerator 30-45 minutes before cooking to bring it to room temperature; this ensures an even cook.

  2. 2

    Pat the steak extremely dry on both sides using paper towels. Moisture is the enemy of a good sear.

  3. 3

    In a small bowl, prepare the salsa verde by combining the finely chopped parsley, minced capers, mashed anchovies, and grated garlic.

  4. 4

    Whisk in the extra virgin olive oil, lemon juice, lemon zest, red wine vinegar, and red pepper flakes until well emulsified. Set aside at room temperature to let flavors marry.

  5. 5

    Season the steak generously on both sides with kosher salt, black pepper, and garlic powder, pressing the spices into the meat.

  6. 6

    Place a large cast-iron skillet over high heat until it is screaming hot and just starting to smoke.

  7. 7

    Add the avocado oil to the skillet, swirling to coat the bottom evenly.

  8. 8

    Carefully lay the skirt steak into the pan. If the steak is too long, cut it into 2 or 3 manageable sections to avoid crowding.

  9. 9

    Sear the steak without moving it for 3-4 minutes, until a deep, dark brown crust has formed.

  10. 10

    Flip the steak and sear the other side for an additional 3 minutes for medium-rare (internal temperature of 130-135°F).

  11. 11

    Transfer the steak to a cutting board and tent loosely with foil. Let it rest for a full 10 minutes to allow juices to redistribute.

  12. 12

    Identify the direction of the grain (the long muscle fibers). Using a sharp knife, slice the steak thinly *against* the grain at a slight diagonal.

  13. 13

    Fan the slices out on a platter and spoon a generous amount of the salsa verde over the top.

💡 Chef's Tips

Always slice against the grain; skirt steak has very long fibers and will be chewy if cut incorrectly. Don't skip the anchovies in the sauce; they provide a savory 'umami' depth and don't taste fishy once mixed. If you can't find outside skirt, inside skirt works but is thinner and cooks faster, so reduce heat time by 1 minute per side. Use a cast-iron skillet for the best crust; stainless steel or non-stick won't provide the same heat retention. Make the salsa verde by hand rather than a food processor for a rustic, chunky texture that looks beautiful.

🍽️ Serving Suggestions

Serve alongside grilled asparagus or roasted broccolini for a complete keto meal. Pair with a glass of bold Malbec or a peppery Syrah to complement the beef and herbs. Add a side of cauliflower mash with plenty of butter and chives. Garnish the plate with a few extra lemon wedges to brighten the flavors at the table. For an extra kick, serve with a small bowl of pickled red onions on the side.
