Ingredients

Instructions

  1. Step 1: Pat steaks dry with paper towels and season both sides evenly with 1/2 tsp sea salt and 1/4 tsp black pepper. Heat 1 tbsp olive oil in a heavy skillet over medium-high heat until shimmering.
  2. Step 2: Add steaks to skillet and cook for 3 minutes without moving to develop a crust, then flip and cook for 3 more minutes for medium-rare.
  3. Step 3: Remove steaks to a plate and tent with foil. Add 2 tbsp unsalted butter and 2 minced garlic cloves to the skillet, stirring until butter melts and garlic is fragrant (about 30 seconds).
  4. Step 4: Add 8 oz sliced cremini mushrooms to skillet and cook, stirring occasionally, for 5 minutes until mushrooms are golden and release their liquid.
  5. Step 5: Return steaks to skillet and spoon mushroom mixture over top. Squeeze 1 tbsp lemon juice over everything and cook for 1 minute to meld flavors before serving.
