Method

Beef and seasoning

  1. 1

    Bring to room temperature

    Remove the 250 g beef tenderloin from the refrigerator 30–45 minutes before cooking and pat dry with paper towel. Bringing it closer to room temperature ensures even cooking.

  2. 2

    Season

    Season all sides of the steak evenly with 1 tsp kosher salt, 1 tsp freshly ground black pepper, and 1 tsp garlic powder. Pat the seasonings gently so they adhere.

Cooking fats & finishing

  1. 3

    Preheat pan

    Place a heavy skillet (cast-iron preferred) over medium-high heat for 3–4 minutes until very hot. Add 1 tbs neutral oil and swirl to coat the pan; the oil should shimmer but not smoke heavily.

  2. 4

    Sear the tenderloin

    Carefully place the seasoned tenderloin in the hot pan. Sear without moving for 2–2½ minutes until a deep brown crust forms. Flip and sear the other side for 2–2½ minutes. Also sear the edges (use tongs to hold the steak) for about 30–45 seconds to render exterior fat and color the sides.

  3. 5

    Baste for flavor

    Reduce heat to medium. Add 1 tbs unsalted butter, the smashed garlic clove, and 2 thyme sprigs to the pan. Tilt the pan slightly and use a spoon to baste the melted butter over the steak continuously for 30–60 seconds while it finishes cooking. This builds flavor and helps the surface finish evenly.

  4. 6

    Check doneness

    For a 250 g (about 1.5–2-inch thick) tenderloin, target internal temperatures: 50–52°C (122–126°F) for rare, 54–57°C (130–135°F) for medium-rare, 60–63°C (140–145°F) for medium. Insert an instant-read thermometer into the center to check. If under target, continue cooking, flipping and basting, in 30-second increments and recheck.

  5. 7

    Rest and finish

    Transfer the steak to a cutting board and tent loosely with foil. Add 1 tsp resting butter on top (optional) and let rest for 5–8 minutes to allow juices to redistribute. While resting, discard the garlic and thyme from the pan or spoon any pan juices over the steak for extra flavor.

  6. 8

    Serve

    Slice the tenderloin against the grain into 2–3 slices or serve whole. Sprinkle with 1 tsp finely chopped parsley (optional) and serve with a lemon wedge if desired.
