First, preheat your oven to 210°F.
Remove the two steaks from the refrigerator 30 minutes before cooking, allowing them to reach room temperature. This will ensure a more consistent cook.
Pat the steaks dry with a paper towel. Then, lightly brush them with avocado oil. Season each side with salt, pepper, and Espelette pepper to add a touch of spice.
Put the seasoned steaks in the preheated oven and cook for 45 minutes and take the steaks out after that.
Next, heat avocado oil in a stainless steel skillet or a cast iron skillet over high heat. When the oil shimmers or ripples, it's ready. Carefully add the first steak to the skillet and sear each side for about 2 minutes to develop a rich brown crust.
Reduce the heat to medium and add butter and garlic to the skillet. As the butter melts, continuously baste the steaks with it for about 1-2 minutes.
To achieve a medium-rare steak, cook for a total of 7-10 minutes, or until it reaches an internal temperature of 132°F. For medium, aim for 140°F. Remember that the cooking time might vary depending on the thickness of your steak.
Once the steak is cooked to your liking, take it out of the skillet and let it rest for about 5 minutes before cutting into it. This rest time allows the juices to redistribute throughout the steak.
Finally, serve the steaks topped with the remaining garlic butter from the skillet and your choice of sides. The generous amount of butter and garlic in this recipe gives the steak a buttery and garlicky flavor.
