What is the best way to cook a filet mignon sous vide for a perfectly tender and juicy result?

To cook a filet mignon sous vide for a perfectly tender and juicy result, first season the steak with salt and pepper, then vacuum-seal it in a bag. Cook it in a water bath at 130F (54C) for 1-2 hours. After cooking, sear the steak in a hot pan for a minute on each side for a nice crust. This method ensures the steak is cooked evenly and retains its juices, resulting in a tender and flavorful filet mignon.
