Cut russet potatoes into thin, long strips resembling string fries. Place them in ice water for 15-20 minutes to remove excess starch.
Heat oil in a deep pot or fryer to 350 degrees Fahrenheit (175 degrees Celsius). Drain the soaked potato strips and pat them dry. Fry the fries in batches for about 5-6 minutes until golden and crispy. Remove and drain them in a foil-lined pan.
Sear the seasoned skirt steak over hot coals or in a preheated grill pan/skillet for approximately 3-4 minutes per side. Let the cooked steak rest for about 8 minutes.
While the steak is resting, return the previously fried fries to the hot oil for a second fry until crispy and golden brown.
Slice the rested skirt steak against the grain into bite-sized portions.
Assemble the dish by arranging the crispy fries (optionally tossed in Potato Slayer rub or seasoning) on a serving dish. Top with the grilled skirt steak slices. Drizzle generously with chimichurri sauce.
