A foolproof grilled porterhouse steak recipe featuring truffle butter and sautéed wild mushrooms, perfect for quick gourmet meals that impress without fuss.

Ingredients

Scale
  • 1 large porterhouse steak (about 24 oz / 680 g), ideally dry-aged or grass-fed
  • 2 tablespoons olive oil (for seasoning)
  • Coarse sea salt and freshly ground black pepper (to taste)
  • 4 tablespoons unsalted butter, softened
  • 1 teaspoon truffle oil (white or black)
  • 1 small garlic clove, minced
  • 1 teaspoon fresh parsley, finely chopped
  • Pinch of sea salt
  • 8 oz (225 g) mixed wild mushrooms (shiitake, oyster, chanterelle, or cremini)
  • 2 tablespoons unsalted butter
  • 1 small shallot, finely diced
  • 1 teaspoon fresh thyme leaves
  • Salt and pepper to taste

Instructions

  1. Take the porterhouse out of the fridge 30-45 minutes before grilling to reach room temperature. Pat dry with paper towels, then rub both sides with olive oil, coarse sea salt, and black pepper. Set aside.
  2. In a small bowl, combine softened butter, truffle oil, minced garlic, parsley, and a pinch of salt. Mix well using a fork or whisk. Transfer to a small piece of parchment paper, roll into a log shape, and refrigerate while you cook.
  3. Clean mushrooms gently with a damp cloth and slice if large. Heat butter in a cast iron skillet over medium heat until melted and bubbling. Add shallots and cook for 1-2 minutes until translucent. Toss in mushrooms and thyme. Sauté for about 6-8 minutes until mushrooms are golden and tender. Season with salt and pepper. Keep warm.
  4. Preheat your grill to high heat (~450-500°F / 230-260°C). If using charcoal, wait until coals are white-hot. Oil the grates lightly to prevent sticking.
  5. Place steak directly over the heat. Grill for about 4-5 minutes per side for medium-rare (internal temp 130°F / 54°C). Use tongs to flip—don’t pierce the meat. For thicker cuts, finish on indirect heat for a few minutes to avoid burning. Rest the steak for 5-10 minutes on a cutting board.
  6. Slice the truffle butter into rounds and place on top of the rested steak so it melts luxuriously. Plate with the sautéed wild mushrooms alongside. Optionally, add a sprinkle of fresh herbs for color.

Notes

Rest the steak after grilling to allow juices to redistribute for maximum juiciness. Use a meat thermometer to ensure perfect doneness. For a deeper crust, sear in a super-hot cast iron pan after grilling. Avoid overcrowding mushrooms when sautéing to develop caramelized flavor. Truffle butter can be made up to 3 days ahead and refrigerated.
