Instructions

  1. Step 1: Remove 12 oz ribeye steak from the fridge 20 minutes before cooking to reach room temperature, then season both sides evenly with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Heat 1 tbsp olive oil in a heavy skillet over medium-high heat until shimmering but not smoking, about 2 minutes.
  3. Step 3: Add the steak and sear for 4 minutes on the first side without moving, then flip and cook for another 3 minutes for medium-rare doneness.
  4. Step 4: Reduce heat to medium-low, add 3 tbsp unsalted butter, 3 minced garlic cloves, 2 tbsp chopped parsley, and 1 tbsp fresh thyme leaves to the pan.
  5. Step 5: Tilt the pan slightly and spoon the melted butter and herb mixture repeatedly over the steak for 2 minutes until the butter is fragrant and the steak is coated.
  6. Step 6: Remove steak from the pan, let rest on a cutting board for 5 minutes to redistribute juices, then slice and drizzle with remaining herb butter before serving.

How do I store leftover Pan-Seared Ribeye with Garlic Butter and Keto Herb Sauce?

Can I substitute ingredients in Pan-Seared Ribeye with Garlic Butter and Keto Herb Sauce?

How do I scale Pan-Seared Ribeye with Garlic Butter and Keto Herb Sauce for a different number of people?
