Ingredients

Scale
  • 2 filet mignon steaks (68 oz / 170225 g each), about 1.5 inches thick
  • Salt (kosher or sea salt preferred)
  • Freshly ground black pepper
  • 2 tablespoons olive oil or avocado oil
  • 8 oz (225 g) cremini or white mushrooms, sliced
  • 3 tablespoons unsalted butter
  • 3 cloves garlic, minced
  • 1 teaspoon fresh thyme leaves (optional)
  • Salt and pepper, to taste
  • Fresh parsley, chopped (for garnish)

Instructions

  1. Bring steaks to room temperature for 15-20 minutes.
  2. Pat steaks dry with paper towels and season generously with salt and freshly ground black pepper on both sides.
  3. Preheat a heavy-bottomed skillet or cast iron pan over medium-high heat for about 5 minutes until very hot.
  4. Add 2 tablespoons of olive oil to the pan. Place steaks in the hot pan and sear without moving for 3-4 minutes until a golden-brown crust forms. Flip and repeat on the other side.
  5. Check temperature with an instant-read thermometer aiming for 125°F (52°C) for medium-rare, adjusting time for preferred doneness.
  6. Remove steaks from pan and tent loosely with foil. Let rest for 5-7 minutes.
  7. Reduce heat to medium. Add butter to the same pan and let it melt.
  8. Add minced garlic and thyme to the melted butter and stir for 30 seconds until fragrant but not browned.
  9. Add sliced mushrooms, season with salt and pepper, and sauté for 5-7 minutes until golden and tender, stirring occasionally.
  10. Plate the rested filet mignon and spoon garlic butter mushrooms over or beside the steaks. Garnish with chopped fresh parsley.

Notes

Bring steaks to room temperature before cooking for even doneness. Pat steaks dry to ensure a good crust. Avoid overcrowding the pan when cooking mushrooms to prevent steaming. Rest steaks after cooking to lock in juices. Use an instant-read thermometer for perfect doneness. For dairy-free, substitute butter with vegan buttery spread or olive oil.
