Here are some expert tips on how to cook a perfect steak:

• Bring the steak to room temperature before cooking to ensure even cooking.
• Use a heavy-bottomed pan such as cast iron and heat it very hot before adding the steak.
• Oil the steak lightly and season both sides generously with salt and freshly ground black pepper.
• For a medium-rare 2.5 cm thick steak, cook on high heat for about 3-4 minutes per side, turning frequently (every minute or so).
• In the last minute of cooking, add butter, garlic cloves, and fresh herbs like thyme or rosemary to the pan. Baste the steak continuously with the melted butter for extra flavor.
• After cooking, let the steak rest for 4-5 minutes to seal in juices.
• For additional flavor, drizzling pan juices or serving with a steak sauce works well.

Additional guidance includes:

• Avoid overcrowding the pan to ensure a good sear.
• Use a high smoke point oil like sunflower or vegetable oil.
• Frequent flipping can help even cooking rather than flipping only once.
• Avoid overcooking to maintain juiciness and tenderness.

These tips will help achieve a juicy, flavorful steak with a nice crust and tender inside.
