Ingredients for this buttery pan seared filet mignon steak

Instructions

  • Let steaks sit at room temperature for 30–60 minutes before cooking.

  • Sprinkle salt and black pepper generously over both sides of the steaks.

  • Preheat your oven to 400°F.

  • Heat butter in a cast iron skillet over medium heat until melted and fragrant. Add garlic, rosemary, and thyme.

  • Cook for 2–3 minutes, swirling the pan often to prevent burning.

  • Raise heat to medium-high. When the pan is hot, gently lay the steaks into the skillet.

  • Sear steaks for 2–3 minutes on each side. Continuously spoon hot butter over them while cooking.

  • Flip and repeat, searing the other side for another 2–3 minutes.

  • Insert a meat thermometer into the center of one steak and move the pan to the oven’s center rack.

  • Bake until internal temp hits 125–130°F for medium-rare.

  • Remove the steaks and let them rest 5–8 minutes. The internal temperature will rise another 5 degrees.

  • Slice and serve with roasted potatoes and your favorite green side.
