Ingredients

Instructions

  1. Step 1: Trim 1 lb sirloin steak of excess fat and dice into 1.5-inch cubes. Season with 1 tsp salt and 1/2 tsp black pepper evenly.
  2. Step 2: Heat 1 tbsp olive oil in a large skillet over medium-high heat until shimmering, about 2 minutes. Add the steak cubes in a single layer and sear for 3-4 minutes without moving until golden brown on one side.
  3. Step 3: Flip steak cubes and cook for another 3 minutes until desired doneness, then remove steak from skillet and set aside.
  4. Step 4: Reduce heat to medium and add 4 tbsp unsalted butter and 4 minced garlic cloves to the skillet. Sauté for 1-2 minutes until garlic is fragrant and butter is melted and slightly bubbling.
  5. Step 5: Return steak bites to the skillet and toss to coat with garlic butter sauce. Cook together for 1 minute until heated through.
  6. Step 6: Remove from heat and sprinkle 2 tbsp chopped fresh parsley over the steak bites before serving.
