Equipment

  • Grill or grill pan
  • Instant-read thermometer
  • Small saucepan

Ingredients
  

For the Steaks:

  • 2 16-ounce, 1¼- to 1½-inch-thick New York strip steaks
  • 2 teaspoons kosher salt
  • 1 teaspoon freshly ground black pepper

For the Mustard-Pepper Sauce:

  • ½ cup 1 stick unsalted butter, cut into 8 pieces
  • 1½ tablespoons stone-ground mustard
  • 1 tablespoon freshly squeezed lemon juice
  • 1 tablespoon coarsely ground black pepper
  • Pinch of fine sea salt
  • 2 sprigs of fresh rosemary

Instructions
 

  • Prep the Steaks: Take the steaks out of the fridge 20 to 30 minutes before cooking to let them come to room temperature. This step helps them cook more evenly.
  • Heat the Grill: Preheat your grill to medium-high heat.
  • Season and Grill: Coat the steaks thoroughly with the kosher salt and ground black pepper. Place them on the hot grill and immediately lower the heat to medium. Let the steaks cook for 4 to 5 minutes on one side until a deep brown crust forms. Flip the steaks and cook them for an additional 4 to 8 minutes, depending on how well-done you prefer them. Use an instant-read thermometer to monitor the temperature; remove the steaks from the grill when they are 5° to 10°F below your target doneness.
  • Rest the Steaks: Set the cooked steaks on a plate, loosely covering them with foil, and allow them to rest for about 10 minutes. This resting period locks in the juices.
  • Prepare the Sauce: In a small saucepan, combine the butter, mustard, lemon juice, black pepper, and sea salt. Set the heat to low and whisk constantly for 2 to 3 minutes, ensuring the butter melts completely and the sauce begins to lightly steam (avoid boiling to keep it smooth). Once steam appears, remove the pan from the heat. Add the rosemary sprigs and let them infuse the sauce for about 30 seconds, then discard them. Keep the sauce warm until serving.
  • Serve: Slice the steaks across the grain for maximum tenderness and arrange the slices on a serving platter. Drizzle the mustard-pepper sauce generously over the steak or serve it on the side for dipping. Enjoy immediately!

Notes

Feel free to swap in more budget-friendly steak cuts like ribeye or top sirloin. Adjust the cooking time based on the thickness of your steak.
For perfect doneness, use these temperature guidelines:
  • Medium-rare: Remove at 130°F to 135°F (will rise to 140°F when served).
  • Medium: Remove at 140°F to 145°F (will rise to 150°F when served).
  • Medium-well: Remove at 145°F to 150°F (will rise to 155°F when served).
Don’t be shy with the seasoning—it’s key to enhancing the flavor of the steak.
This mustard-pepper sauce also works beautifully with chicken, pork, or roasted vegetables.
