Recipe: Black Steel Roasted Grass Fed Skirt Steak with a Balsamic and Rosemary Glaze

Our grass fed and grass finished Skirt Steak is a supremely flavorful cut, but because it is thin it cooks really quickly over high heat. It only requires a few minutes in a simple steel or cast iron pan. So you’ll need to make sure your sauce is powerfully flavorful and straightforward because it won’t have a lot of time to interact with the beef. That’s why a secondary glaze is so great here- it picks up all the flavors of the marinade and amplifies them.

Course: Main Course
Author: Katy Sparks


  • 2 lbs skirt steak, trimmed if needed
  • 2 Tbsp rendered fat

For the Marinade

  • 2 cloves garlic, thinly sliced
  • 4 Tbsp shoyu or soy sauce
  • 2 Tbsp toasted sesame oil
  • 1 tsp dried red chili flakes
  • 4 Tbsp balsamic vinegar

For the Glaze

  • 1 cup balsamic vinegar
  • 1 Tbsp rosemary, minced
  • 1 Tbsp honey


  • Combine all of the marinade ingredients and pour over the skirt steak, turning until the steak is evenly coated. Marinate in the refrigerator for 2 hours.
  • In a non-reactive pan, combine all the glaze ingredients and very slowly reduce at a low simmer until the glaze coats the back of a spoon.
  • Heat a cast iron or steel pan with the rendered fat until the fat is shimmering.
  • When ready to cook the steak, drain most of the marinade off and lightly blot the skirt steak with paper towels. Add the steak carefully and cook 2-3 minutes per side until you get a deep browning.
  • Let the steak rest on a cutting board for at least 5 minutes before slicing into thin angled slices.
  • Drizzle the sliced skirt steak with the balsamic-rosemary glaze.


Tip: When slicing skirt steak before serving, observe that the meat will have a direction or “grain” running across the short length of the piece. For best texture, slice the meat so your knife is cutting across these strands of muscle. If you slice along the same direction of the grain of the meat, it will be much chewier, so we always recommend cutting across the grain.

    So glad I found this recipe. It’s a keeper. Son just butchered the first of his grass fed cows ( 100% grass fed) and we are so enjoying the meat. Everyone enjoyed this dish.
