Ingredients Equipment Method Notes

Ingredients
  

  • 1.5 lb boneless sirloin steak trimmed and cut into 1-inch cubes
  • 1 tsp kosher salt
  • 0.5 tsp black pepper
  • 2 tbsp neutral oil divided
  • 8 oz cremini mushrooms halved or quartered
  • 4 tbsp unsalted butter divided
  • 4 cloves garlic minced

Equipment

  • 1 12-inch skillet

Method
 

  1. Pat the steak dry with paper towels, then season it evenly with the salt and pepper.
  2. Heat 1 tablespoon oil in a 12-inch skillet over medium-high heat until shimmering. Sear half the steak in a single layer, turning the pieces as they brown, until browned and at least 145°F in the center, about 4 to 6 minutes; transfer to a plate and repeat with the remaining oil and steak.
  3. Reduce the heat to medium and add 2 tablespoons butter and the mushrooms to the skillet. Cook, stirring occasionally, until the mushrooms are browned and tender, about 5 to 7 minutes.
  4. Add the remaining 2 tablespoons butter and the garlic, and cook, stirring, until fragrant, about 30 seconds.
  5. Return the steak and any accumulated juices to the skillet and toss until coated and hot, about 1 minute.
  6. Rest for 3 minutes before serving.

Notes

Sear the steak in batches without crowding the skillet for better browning. Refrigerate leftovers for up to 3 days; freezer storage is suitable. For a dairy-free swap, use plant-based butter.
