Skirt Steak Tacos With Picked Onions And Lime Crema
Bold, smoky skirt steak with a citrus-spice marinade, quick pickled onions, and a drizzle of lime crema. A taco that tastes restaurant-worthy and takes about an hour from start to table.
Whisk together the olive oil, Worcestershire sauce, lime juice, cumin, coriander, chili powder, garlic powder, onion powder, salt, and pepper in a small bowl.
Place the skirt steak in a shallow dish or zip-top bag. Pour the marinade over it and turn to coat. Refrigerate for at least 30 minutes, or up to 4 hours. Pull the steak from the fridge 30 minutes before cooking.
Make the orange pickled red onions. Add the sliced red onion to a heatproof jar or bowl. In a small saucepan, combine the vinegar, water, sugar, and salt. Bring to a simmer, stirring until dissolved. Remove from heat, stir in the orange peel and orange juice, and pour over the onions. Let sit for at least 30 minutes.
Make the lime crema. In a small bowl, stir together the sour cream, 2 tablespoons lime juice, orange juice, garlic, cumin, and a pinch of salt. Taste and adjust.
When ready to grill, remove the steak from the marinade and allow the excess to drip off. Cook on a hot grill or cast iron skillet over high heat for 2 to 4 minutes per side, until charred and cooked to medium-rare (about 130°F). Transfer to a cutting board and rest for 5 to 10 minutes.
Slice the skirt steak thinly against the grain.
Warm the corn tortillas on a dry skillet or over a gas flame until soft and lightly charred.
Assemble: layer steak on each tortilla and top with orange pickled red onions, cotija, cilantro, and a drizzle of lime crema. Add avocado slices. Finish with a squeeze of lime.
Notes
Marinate for at least 30 minutes. Two to four hours gives noticeably more flavor.
Pull the steak from the fridge 30 minutes before cooking — this helps it cook more evenly throughout.
Cook over very high heat to get proper char. Medium heat leads to a steamed result without the flavor.
Slice against the grain. Look at the direction the muscle fibers run and cut perpendicular to them. This is what makes skirt steak tender.
For grilling: preheat to at least 500°F. Grill 3 to 4 minutes per side, pulling at 130°F internal temp. Rest 5 minutes before slicing.
The pickled onions keep in the fridge for up to 2 weeks. Make a big batch.
Leftover steak reheats best in a hot skillet for 1 to 2 minutes, not the microwave.
