Before you start

Before beginning, gather all necessary equipment and ingredients to ensure a smooth cooking process. Take the steaks out of the refrigerator exactly thirty minutes before cooking to bring them closer to room temperature, which promotes even cooking.

Finely mince the garlic and measure out the butter and fresh thyme sprigs. Heat the cast-iron skillet over high heat until it is smoking hot. Ensure a reliable instant-read meat thermometer is nearby to monitor the internal temperature accurately.

Ingredients at a glance (4)
  • 2 thick-cut steaks
  • 4 tbsp butter
  • 3 cloves garlic, minced
  • 4 sprigs fresh thyme

Instructions

Searing the Crust

  1. Prepare the Steaks
    Pat the steaks completely dry with paper towels. Ensure the surface is dry to the touch, which promotes a much better sear when the meat hits the hot pan.
    Look for The steaks should be dry to the touch.
    Tip Dry surfaces promote a much better sear.
  2. Sear the Steaks
    Heat a heavy cast-iron skillet over high heat until smoking. Place the steaks in the hot pan and sear without moving for two to three minutes until a deep, caramelized crust forms. Flip and sear the other side.
    Look for A deep, dark brown crust should form on the bottom side.
    Tip Do not move the steaks while they sear.

At the end of this phase, the steaks should have a deeply caramelized, dark brown crust on both sides. The skillet will be hot, and the meat should release easily from the pan when flipped. The kitchen will fill with a rich, savory aroma of seared beef. Do not move the steaks prematurely; let the crust form completely before flipping to ensure a perfect sear.

Butter Basting

  1. Baste with Garlic Butter
    Reduce the heat slightly and add the butter, minced garlic, and fresh thyme sprigs to the skillet. Tilt the pan and spoon the foaming garlic butter continuously over the steaks for two minutes until the internal temperature reaches 145°F (63°C) for safe consumption, then let the meat rest for at least 3 minutes.
    Look for The butter will foam and the garlic will become highly aromatic.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Keep the butter moving to prevent the garlic from burning.

During this phase, the butter will melt rapidly and begin to foam, turning a light golden brown. The minced garlic and fresh thyme sprigs will release an intense, aromatic fragrance into the air.

As the hot, seasoned butter is spooned continuously over the steaks, the meat will take on a glossy, decadent finish while reaching its final target temperature of 145°F (63°C) for a safe, medium doneness.

Resting and Slicing

  1. Rest the Steaks
    Transfer the basted steaks to a clean wooden board. Let the meat rest for at least three minutes to allow the juices to redistribute and ensure maximum tenderness.
    Look for The meat rest must be at least three minutes.
    Tip Never skip resting or the juices will run out.
  2. Slice and Serve
    Slice the rested steak against the grain into thick, even slices. Pour the remaining warm garlic butter from the pan over the top and serve immediately.
    Look for The interior should show a warm pink color with rising steam.
    Tip Slice against the grain for the most tender bite.

At the final checkpoint, the cooked steaks must rest on a clean wooden board for at least three minutes. This allows the hot juices to redistribute throughout the meat, ensuring a tender and juicy interior. Slicing through the rested steak should reveal a perfectly cooked, warm pink center with rising steam, ready to be served immediately with the remaining melted butter poured over the top.

Common mistakes

One common mistake is crowding the pan or using a skillet that is not hot enough, which causes the steaks to steam rather than sear. Another error is basting too early; adding the butter at the start of cooking will cause the milk solids to burn, resulting in a bitter flavor.

Lastly, cutting into the steak immediately after cooking without resting will cause all the delicious juices to run out onto the board, leaving the meat dry.

How to tell it’s done

To ensure the steak is cooked safely and perfectly, always use an instant-read meat thermometer. Insert the probe into the thickest part of the steak, avoiding any bone or fat.

For safe consumption, whole cut beef must reach an internal temperature of at least 145°F (63°C), followed by a mandatory three-minute rest period. This resting time allows the temperature to stabilize and ensures the meat remains exceptionally juicy and tender before slicing.
