Instructions
- Step 1: Pat dry 12 oz ribeye steak and season both sides with 1 tsp salt and 1/2 tsp black pepper. Let rest at room temperature for 15 minutes.
- Step 2: Heat 1 tbsp extra virgin olive oil in a heavy skillet over medium-high heat until shimmering. Add the steak and sear for 4 minutes without moving to develop a crust.
- Step 3: Flip the steak and add 3 tbsp unsalted butter, 3 minced garlic cloves, and 2 fresh thyme sprigs to the pan. Tilt pan and spoon the melted butter over the steak continuously for 3-4 minutes until the internal temperature reaches 130°F for medium-rare.
- Step 4: Remove steak and let rest on a plate tented with foil for 5 minutes.
- Step 5: In the same skillet, add 5 cups fresh baby spinach and sauté over medium heat for 2 minutes until wilted. Season with a pinch of salt and 1 tsp lemon juice to brighten.
- Step 6: Slice the steak against the grain, drizzle with the garlic butter from the pan, and serve with the wilted spinach.
