Ingredients

Scale
  • 4 filet mignon steaks, about 6 ounces (170 grams) each, trimmed and at room temperature
  • 4 tablespoons (about 57 grams) unsalted butter, softened
  • 1 teaspoon chopped fresh rosemary
  • 1 teaspoon chopped fresh thyme
  • 1 tablespoon chopped fresh parsley
  • 2 cloves garlic, minced
  • Kosher salt, for seasoning
  • Freshly ground black pepper, to taste
  • 1 tablespoon (15 ml) olive oil, for brushing

Instructions

  1. Prepare the Herb Butter (10 minutes plus chilling): In a small mixing bowl, combine the softened unsalted butter, minced garlic, chopped rosemary, thyme, and parsley. Mix thoroughly until evenly incorporated. Transfer the butter mixture onto plastic wrap, roll into a log shape, and chill in the fridge for at least 30 minutes to firm up before slicing.
  2. Season the Steaks (5 minutes): Remove filet mignons from the fridge about 20 minutes before grilling to reach room temperature. Pat dry with paper towels, brush lightly with olive oil, and season generously with kosher salt and freshly ground black pepper on all sides.
  3. Preheat the Grill (10 minutes): Heat grill to high, around 450°F (232°C). For charcoal grills, let coals ash over and spread evenly. Clean grill grates well to prevent sticking.
  4. Grill the Steaks (8-10 minutes): Place steaks on the hottest part of the grill. Cook about 4-5 minutes per side for medium-rare (internal temp 130°F/54°C). Flip only once using tongs to develop a good sear. For medium, add 1-2 minutes per side.
  5. Rest the Steaks (5-7 minutes): Remove steaks from grill, place on a warm plate, top each with a slice of chilled herb butter, cover loosely with foil, and let rest to redistribute juices and melt butter.
  6. Serve and Enjoy: Plate steaks with preferred sides such as roasted vegetables or garlic mashed potatoes. Spoon melted herb butter over the top.

Notes

Bring steaks to room temperature before grilling for even cooking. Use a meat thermometer to achieve perfect doneness (130°F for medium-rare). Avoid piercing the meat to retain juices. Clean grill grates before cooking to prevent sticking. Herb butter can be made up to 3 days ahead and stored in the fridge. For dairy-free option, substitute butter with a plant-based spread.
