Instructions
In a bowl or large zip-top bag, combine the soy sauce, Worcestershire sauce, fresh lime juice, chopped garlic, and brown sugar. Whisk or stir until the brown sugar is mostly dissolved.
Add the skirt steak to the marinade, turning to coat it evenly. Seal the bag or cover the bowl and refrigerate for at least 2 hours, or overnight for best flavor. Turn the steak halfway through marinating if possible.
In a separate bowl or zip-top bag, combine the water, soy sauce, Worcestershire sauce, and 2 tablespoons of neutral oil. Add the onions and peppers and toss to coat. Let the vegetables marinate for at least 30 minutes or up to 2 hours.
Remove the steak from the refrigerator 30 minutes before cooking so it can warm up a bit. Remove it from the marinade and pat it completely dry with paper towels. Discard the used marinade.
Heat a heavy cast-iron skillet over high heat until very hot and nearly smoking. Add 1 tablespoon of oil. Place the steak in the skillet and sear for 3 to 4 minutes per side for medium-rare, or until a dark crust forms. Do not move the steak while it is searing.
Transfer the steak to a cutting board and let it rest for 5 minutes. Slice it thinly against the grain before serving.
While the steak rests, heat 1 tablespoon of oil in a second skillet over medium-high heat. Remove the onions and peppers from the marinade and discard the used marinade. Add the onions and peppers to the skillet and cook for 3 to 5 minutes, until the vegetables are tender and lightly charred around the edges. Finish with 1 teaspoon of lime juice and stir to combine. Remove from the heat.
For sizzling service, heat a dry cast-iron skillet over high heat for 3 to 4 minutes until very hot. Carefully add 2 tablespoons of water to the skillet. It will steam immediately. Arrange the steak slices, peppers, and onions on the hot skillet. Place the hot skillet on a heat-proof trivet and serve immediately.
Warm the flour tortillas by wrapping them in a damp paper towel and microwaving for about 30 seconds.
Serve the steak, peppers, and onions with warm tortillas, shredded Colby Jack cheese, sour cream, pico de gallo, guacamole, and lime wedges.
Recipe Tips
Before marinating, trim any visible fat and silvery gristle from the skirt steak so the marinade can penetrate the meat directly. Skirt steak has long, visible muscle fibers running in one direction, so take note of that grain before it goes into the marinade. After cooking, you'll slice against those fibers rather than parallel to them, which is what keeps the finished steak tender instead of stringy.
Keep the steak at medium-rare. Skirt steak has looser muscle fibers than cuts like ribeye, and pushing it past medium turns it chewy fast.
Let the cast-iron skillet get properly hot and slightly smoking before the steak goes in. A cooler pan means the beef steams instead of searing, and you lose the browned crust.
The splash of water in the sizzle-platter step creates the audible sizzle and steam Chili's is known for, but it's purely presentation. Skip it and the dish tastes the same.
Resting the steak both before cooking (to room temperature) and after cooking (on the cutting board) matters just as much as the sear itself for a juicy result.
