Ingredients

  • 4 12 ounce filet mignon steaks
  • 2 tablespoons extra virgin olive oil
  • 1 ½ tablespoons kosher salt
  • 1 ½ tablespoons coarse ground pepper
  • 1 ½ tablespoons granulated garlic

Brown Butter Sauce

  • 1 tablespoon extra virgin olive oil
  • 8 tablespoons unsalted butter (plus 1 tablespoon for sauté)
  • 6 ounces cremini mushrooms, cleaned and sliced
  • 2 tablespoons diced shallots
  • 2 cloves garlic cloves, minced
  • 2 tablespoons diced fresh sage
  • ½ teaspoon kosher salt

Instructions

For the Grilled Filet Mignon

  • Remove filet from the refrigerator. Pat dry and allow them to come to room temperature (30 minutes to 1 hour).
  • While filets are coming to room temperature, prepare grill for two zone or direct indirect method. Ideally the temperature directly above the charcoal is over 500 degrees.
  • Lightly coat the steaks with olive oil. Combine the salt, pepper, and garlic in a small bowl and apply liberally to the steaks, including the sides.
  • Place the steaks over direct heat for 2 minutes (enough to get a sear, but not burned). Flip the steaks and cook the other side for additional 2 minutes.
  • Move the steaks to the indirect side of the grill, and finish cooking until the internal temperature of the steak is 125 - 130 degrees F for rare (or longer for your preferred finishing temperature). Remove steaks and let rest. While resting prepare the brown butter.

For the Mushroom Brown Butter Sauce

  • In a large skillet over medium heat, add one tablespoon of butter and one tablespoon olive oil. Allow butter to melt and then add mushrooms. Saute mushrooms for 10 - 12 minutes to brown and slightly caramelize.
  • After 10 - 12 minutes add shallots and garlic, and saute for additional 4 minutes to soften. Remove the mushroom, shallot, garlic mixture from the pan and set aside.
  • In the same pan, add the remaining 8 tablespoons of butter over medium heat. Bring butter to a small simmer, stirring occasionally for additional 10 minutes or until the butter starts turning brown and has a nutty aroma. Add back the mushrooms, shallots, and garlic mixture to the brown butter. Finally add salt and sage and immediately remove from heat, stirring to combine.
  • Spoon brown butter over the steak and serve.
