- Let the steaks sit at room temperature for about 30 minutes before cooking so they cook more evenly from edge to center.
- Pat the filet mignon very dry with paper towels before seasoning. Removing surface moisture is key to getting a deep, golden-brown crust.
- Use a heavy, oven-safe skillet (cast iron is ideal) for the best sear. Avoid non-stick pans for high-heat cooking.
- Sear in a little high-heat oil first, then add butter toward the end of cooking for rich flavor without burning the butter.
- For medium-rare, aim for a final internal temperature of 130°F–135°F. Pull the steaks from the oven about 5°F before your target, as they will continue to cook while resting.
- Always use an instant-read thermometer and insert it into the center of the thickest part of the steak. Time is just a guideline – temperature is the most accurate way to know when your filet mignon is done.
- Let the steaks rest for about 10 minutes before serving so the juices can redistribute. This is the secret to a juicy, tender filet mignon.
- Optional but highly recommended: top each hot steak with a slice of steakhouse butter while it rests so it melts over the top and into every bite.
