A straightforward and delicious grilled T-bone steak recipe topped with a flavorful garlic herb butter that melts perfectly to infuse rich, buttery notes and fresh herbs.

Ingredients

Scale
  • 1 thick-cut T-bone steak (about 1 to 1.5 inches thick, 1620 oz / 450-570g)
  • 4 tablespoons unsalted butter (about 60g), softened
  • 3 cloves garlic, minced
  • 1 tablespoon finely chopped fresh parsley
  • 1 tablespoon finely chopped fresh thyme
  • 1 tablespoon finely chopped fresh rosemary
  • Coarse kosher salt, to taste
  • Freshly ground black pepper, to taste
  • 1 tablespoon olive oil

Instructions

  1. Bring the T-bone steak to room temperature by letting it sit covered on the counter for 20-30 minutes.
  2. In a small bowl, combine softened unsalted butter with minced garlic, chopped parsley, thyme, and rosemary. Mix well and set aside.
  3. Preheat the grill to high heat, around 450°F to 500°F (230°C to 260°C). If using charcoal, wait until coals are glowing red with a light ash coating.
  4. Brush both sides of the steak with olive oil. Season generously with coarse kosher salt and freshly ground black pepper on both sides.
  5. Place the steak on the hottest part of the grill. Grill uncovered for 4-5 minutes per side for medium-rare (internal temperature about 130°F / 54°C). For thicker cuts, grill a bit longer. Avoid flipping more than once or twice.
  6. During the last minute of grilling, dollop about half of the garlic herb butter on top of the steak and close the grill lid to let it melt.
  7. Remove the steak from the grill and transfer to a cutting board. Tent loosely with foil and let it rest for 5-10 minutes to allow juices to redistribute.
  8. Slice the steak off the bone, spread the remaining garlic herb butter on top, and serve immediately.

Notes

Use a meat thermometer to ensure perfect doneness (130°F for medium-rare). Let the steak rest after grilling to keep it juicy. Add garlic herb butter during the last minute to avoid burning. Control flare-ups by moving steak to cooler side if needed. Butter can be prepared ahead and refrigerated. If no grill is available, use a cast-iron skillet or grill pan on stove.
