Easy Garlic Butter Beef Tenderloin is an elegant yet simple main dish perfect for special occasions. Tender roasted beef is finished with a rich, garlicky herb butter that enhances its natural flavor for a restaurant-quality result.

Ingredients

  • 1 whole beef tenderloin (about 34 lbs), trimmed
  • Salt and freshly ground black pepper
  • 2 tbsp olive oil
  • 6 tbsp unsalted butter
  • 4 cloves garlic, minced
  • 1 tbsp fresh rosemary or thyme, chopped
  • 1 tbsp fresh parsley, chopped (optional, for garnish)

Instructions

  1. Preheat oven to 425°F (220°C). Pat the beef tenderloin dry and season generously with salt and pepper on all sides.
  2. Heat olive oil in a heavy skillet over medium-high heat. Sear the tenderloin for 2–3 minutes on each side until browned all over.
  3. In a small saucepan, melt butter with garlic and herbs over medium heat. Cook until fragrant, about 1–2 minutes, then remove from heat.
  4. Transfer seared tenderloin to a baking dish or oven-safe skillet. Brush with some of the garlic butter.
  5. Roast for 25–30 minutes or until internal temperature reaches 130–135°F for medium-rare. Baste with more garlic butter halfway through.
  6. Remove from oven and let rest for 10–15 minutes. Slice and drizzle with remaining garlic butter before serving. Garnish with fresh parsley if desired.

Notes

  • Add a splash of balsamic or Worcestershire sauce to the butter for extra flavor.
  • Use compound butter with Dijon or blue cheese for variation.
  • Serve over mashed potatoes, polenta, or roasted vegetables.
  • Finish with flaky sea salt for a gourmet touch.
  • Use a meat thermometer to ensure perfect doneness.
