Instructions

1. Step 1: Preheat a clean steel plate or cast iron skillet over medium-high heat for 5 minutes until hot but not smoking. Pat dry 12 oz beef ribeye steak and season both sides with 1 tsp salt and 1/2 tsp black pepper.
2. Step 2: Add 2 tbsp olive oil to the hot steel plate and place the steak down. Sear for 4 minutes without moving until a deep crust forms, then flip and sear the other side for 3 minutes for medium-rare.
3. Step 3: While the steak cooks, melt 3 tbsp unsalted butter in a small pan over low heat with 4 minced garlic cloves and cook gently for 2 minutes until fragrant and softened but not browned.
4. Step 4: Remove the steak from the steel plate and let it rest on a cutting board for 5 minutes. Spoon the garlic butter over the steak and sprinkle 1 tbsp chopped fresh parsley before serving.
