  • 1/4 cup heavy cream
  • 3 Tbsp. chopped tarragon

Food Preparation

  • Tie the steaks in two places with kitchen twine to help it keep its shape and season generously with salt and pepper. Refrigerate uncovered for minimum 1 hour, maximum 8 hours.

Vegetable Chips

  1. Position racks in the upper and lower third of the oven and heat your oven to 425 degrees Fahrenheit.
  2. Cover a baking sheet with parchment paper.
  3. Toss the parsnips in a bowl with 1/2 tsp. of olive oil and place in a row on the baking sheet
  4. Add the carrots to the bowl with another 1/2 tsp. of olive oil and toss. Place in a row on the baking sheet.
  5. Take all of the beets and toss in 1/2 tsp. of olive oil. Create a third row on the baking sheet and spread evenly.
  6. Sprinkle the chopped rosemary, 1/2 tsp. salt, and 1/4 tsp. pepper over the parsnips, carrots, and beets.
  7. Put the baking sheet on the top rack of the oven. Gently toss every 15 minutes until the vegetables are crisp and browned (about 30 minutes).

Filet Mignon

Filet mignon on counter
  1. Heat a large cast iron skillet on medium high and add 1 1/2 tsp. oil.
  2. Sear the sides of the filets until browned (about 10 minutes for each steak), adding oil to the pan as needed.
  3. Place the steaks on a rimmed baking sheet and put in the oven for 15 to 25 minutes or until the filets have reached the desired temperature (125–130 degrees Fahrenheit for rare, 135–140 degrees Fahrenheit for medium rare).
  4. Remove the steaks from the oven, transfer to a cutting board, and tent with foil to let the meat rest.

Marsala Miso Mustard Sauce

Butter melting on stovetop
  1. In a saucepan, melt butter on medium high.
  2. Add the shallots and saute until lightly browned (5 to 6 minutes).
  3. Add the wine and continue to cook for about 5 minutes until completely absorbed.
  4. Add in the miso broth and mustard. Cook for about 25 to 30 minutes or until reduced to 1 cup (a measuring cup can be used).
  5. Slowly whisk in the cream and reduce heat to low to keep warm.
  6. Shortly before serving, return the vegetables to the oven to warm for about 2 minutes. Whisk 2 Tbsp. of tarragon into the mustard sauce.


  1. Divide the vegetables and place them on one side of the four plates. Swirl the mustard sauce on the empty side of the plate and lightly drizzle on the vegetables.
  2. Remove the strings from the steaks, cut the filet into 1/2 inch thick slices, and fan the steak slices on the mustard sauce next to the vegetables.

Finished Dish

Garnish the steak with flaky sea salt, the remaining tarragon, and rosemary sprigs and serve! You can find more recipes like this on the WebstaurantStore Instagram.
