Ingredients:

  • 1.5 lbs sirloin steak, cut into 1-inch cubes
  • 1 lb Yukon Gold potatoes, cut into ½-inch cubes
  • 2 tbsp olive oil
  • 1 tsp kosher salt
  • ½ tsp black pepper
  • 4 tbsp unsalted butter
  • 4 cloves garlic, minced
  • 1 tbsp fresh parsley, finely chopped
  • ¼ tsp red pepper flakes

Instructions:

  1. Cube the sirloin steak into 1-inch pieces and Yukon Gold potatoes into ½-inch pieces to ensure even cooking.
  2. Toss steak and potatoes in separate bowls with salt and pepper immediately before cooking.
  3. Heat 1 tbsp olive oil in a 12-inch cast iron skillet over medium-high heat until shimmering.
  4. Add potatoes in a single layer and sear undisturbed for 3-4 minutes to develop a golden-brown crust; stir and cook for another 5-7 minutes until tender, then remove from pan.
  5. Add the remaining 1 tbsp olive oil to the skillet and increase heat to high.
  6. Sear steak bites in a single layer for 1-2 minutes per side until a deep mahogany crust forms, then return the cooked potatoes to the pan.
  7. Reduce heat to medium and add unsalted butter and minced garlic.
  8. Toss steak and potatoes constantly for 1-2 minutes until the butter foams and coats the ingredients in a glossy glaze.
  9. Remove from heat and stir in fresh parsley and red pepper flakes.
