Filet Mignon

Mashed Potatoes

Method

Filet Mignon

  1. 1

    Prepare the Steak

    Remove the filet mignon from the refrigerator and let it come to room temperature for about 30 minutes. This will help it cook evenly.

  2. 2

    Season the Steak

    Generously season both sides of the filet mignon with salt and black pepper.

  3. 3

    Sear the Steak

    In a skillet over medium-high heat, add the olive oil. Once hot, add the filet mignon and sear for about 4-5 minutes on each side for medium-rare, or until desired doneness.

  4. 4

    Add Butter and Thyme

    During the last minute of cooking, add the butter and thyme to the skillet. Spoon the melted butter over the steak to enhance the flavor.

  5. 5

    Rest the Steak

    Remove the steak from the skillet and let it rest for about 5 minutes before slicing.

Mashed Potatoes

  1. 6

    Prepare the Potatoes

    Peel and quarter the russet potatoes. Place them in a large pot, cover with cold water, and add a pinch of salt.

  2. 7

    Boil the Potatoes

    Bring the water to a boil over high heat. Once boiling, reduce heat to medium and cook the potatoes until tender, about 15-20 minutes.

  3. 8

    Drain and Mash

    Drain the potatoes and return them to the pot. Add the butter, heavy cream, salt, and black pepper. Mash until smooth and creamy.

  4. 9

    Serve

    Transfer the mashed potatoes to a serving dish and serve alongside the filet mignon.
