Toss potatoes with olive oil, paprika, garlic powder, salt, and pepper, spread on a baking tray and roast for 35 - 40 minutes, turning halfway, until crispy.
While the potatoes roast, rub steaks with Worcestershire sauce, olive oil, salt, pepper, and cumin.
Heat a pan over high heat. Sear the steaks for 2- 3 minutes per side for medium-rare (or longer if preferred).
Rest the steaks for 5 minutes, then slice thinly.
Spread crispy potatoes on a large serving plate and sprinkle the grated cheese over and let it melt slightly.
Add sliced steak, then drizzle with sour cream and hot sauce.
Garnish with spring onions, chilli, and fresh coriander.
