Garlic Rosemary Beef Tenderloin

Roast a Garlic Rosemary Beef Tenderloin with a bright horseradish cream for an elegant, easy centerpiece.

Ingredients

• 4 cloves garlic (minced)
• 1 tablespoon chopped fresh rosemary
• 1 tablespoon chopped fresh thyme leaves
• Kosher salt and freshly ground black pepper (to taste)
• 1 (4-pound) beef tenderloin (trimmed and tied into 2-inch sections)
• 1 tablespoon olive oil

For the horseradish cream sauce :

• 1/2 cup sour cream
• 1/4 cup mayonnaise
• 2 tablespoons prepared horseradish
• 2 tablespoons chopped fresh chives
• Kosher salt and freshly ground black pepper (to taste)

Instructions

Step 1: Make the horseradish cream sauce

Whisk together sour cream, mayonnaise, prepared horseradish and the chopped chives in a medium mixing bowl until smooth and slightly glossy; taste and season with kosher salt and freshly ground black pepper. Spoon the sauce into a small ceramic serving bowl, cover or nestle it in the fridge so the flavors meld and chill while you prepare the beef — this cool, creamy condiment will be bright, tangy and thick enough to hold a spoonful on each slice.

Step 2: Prep the roasting sheet and oven

Preheat the oven to 275°F and line a rectangular baking sheet with aluminum foil, then mist the foil lightly with nonstick spray so the beef releases cleanly later. Keep a small prep bowl and your utensils nearby: a shallow bowl for the herb-garlic paste and a wooden spoon for mixing — everything staged simply and cleanly on the painted white pine surface.

Step 3: Make the garlic-herb rub

In a small bowl combine the minced garlic, chopped fresh rosemary, chopped fresh thyme, kosher salt and freshly ground black pepper; mix to form a coarse, fragrant paste with visible flecks of herb and garlic. The mixture should smell potent and fresh, the herbs still bright green against the pale garlic, ready to cling to the meat when pressed into the surface.

Step 4: Oil, season, and arrange the tenderloin

Pat the trimmed, tied beef tenderloin dry with paper towels, drizzle evenly with olive oil and gently press the garlic-herb mixture all over the exterior so the paste adheres and creates a textured crust. Place the prepared tenderloin, tied into its 2-inch sections, onto the foil-lined rectangular baking sheet, tuck a small bowl with any remaining rub and the wooden spoon nearby.

Step 5: Roast and rest

Roast the tenderloin in the preheated oven until the internal temperature reaches about 130–135°F for medium-rare (times will vary by weight), then remove and let the whole roast rest undisturbed for about 10 minutes so juices redistribute and the meat firms slightly for clean slicing. During resting the crust remains textured and concentrated with herb and garlic fragments clinging to the browned surface.

Step 6: Slice and serve with horseradish cream

Slice the rested tenderloin into thick, lustrous pieces that reveal a warm pink center and a richly browned, herb-speckled crust. Arrange the slices on a rectangular serving platter to mirror the baking sheet’s geometry, place the chilled horseradish cream in the same small ceramic bowl alongside, scatter a few fresh chives and a sprig of rosemary for color, and serve immediately while the meat is warm and succulent.

Notes

• Use an instant-read thermometer to pull the roast at the right temperature.
• Keep the horseradish cream chilled and separate until serving for best texture.
• Let the roast rest at least 10 minutes before slicing for cleaner cuts.
• Ask your butcher to trim and tie the tenderloin if you want consistent cooking.
• Taste the horseradish cream while mixing and adjust heat gradually.
