Instructions

Preheat and Prepare Steaks: Preheat your grill to medium-high heat, around 450°F (230°C). Pat the tenderloin steaks dry with paper towels to ensure a good sear, then brush both sides lightly with olive oil.
Season the Steaks: In a small bowl, combine kosher salt, black pepper, garlic powder, and onion powder. Rub this seasoning evenly onto both sides of each steak to infuse flavor.
Grill the Steaks: Place the seasoned steaks on the hot grill. Cook for 4–5 minutes per side for medium-rare, or adjust cooking time to your preferred doneness. Use a meat thermometer for accuracy: 130°F for medium-rare, 140°F for medium.
Prepare Herb Butter: While the steaks grill, mix softened unsalted butter with minced garlic and chopped fresh rosemary or thyme in a small bowl to create the compound butter.
Rest and Serve: Once the steaks are cooked, transfer them to a plate and top each with a spoonful of the herb butter. Let the steaks rest for 5 minutes to redistribute juices, then serve with optional lemon wedges.

Notes

Bring steaks to room temperature before grilling for more even cooking.
You can substitute the homemade compound butter with store-bought garlic butter for convenience.
Letting the meat rest after grilling helps keep it juicy and tender.
