Ingredients:
1 whole (6 lb.) beef tenderloin, trimmed of visible fat and silver skin
1/2 c. red wine
1 1/2 Tbsp. fresh juice from 1-2 lemons, divided
3 Tbsp. olive oil, divided
3 medium garlic cloves, minced (about 1 Tbsp.)
1 tsp. dried oregano
1/2 tsp. dried thyme
4 tsp. fresh dill, divided use
Kosher salt and freshly ground black pepper
1/2 c. homemade or store-bought low-sodium beef or chicken stock
2 Tbsp. butter
CREAM:
1 1/2 c. sour cream
2 tsp. prepared horseradish
2 Tbsp. minced fresh flat-leaf parsley
2 tsp. minced fresh mint leaves

Directions:
Place trimmed beef tenderloin in a resealable plastic bag.  Add wine, 1 Tbsp. lemon juice, 1 1/2 Tbsp. olive oil, garlic, oregano, thyme, 2 tsp. dill and 1/2 tsp. each salt and pepper.  Seal, squish around to combine and place in the refrigerator to marinate for 4-6 hours.

When ready to cook, adjust oven rack to lower-middle position and preheat oven to 425 degrees.  Remove meat from the refrigerator and pat dry with paper towels.

Season meat with salt and pepper.  Fold small end of tenderloin back on itself by a few inches to create an even thickness.  Secure meat with kitchen twine at 2 inch intervals to create an evenly sized roast.

Heat 1 1/2 Tbsp. oil in a large, oven-safe roasting pan or Dutch oven until shimmering.  Sear meat until well browned on all sides, about 8 minutes total.  Add marinade to the pan and scrape up any browned bits from the bottom of the pan.  Transfer meat to the oven to cook until meat reaches an internal temperature of 125 degrees as registered on an instant read thermometer for medium-rare, 20-30 minutes.

Remove meat from the oven, transfer to a platter and allow to rest for 10 minutes.  While the meat is resting, deglaze the pan on the stove top over medium-high heat, adding beef broth and scraping up browned bits from the bottom of the pan using a wooden spoon.  Swirl in butter to finish sauce.  Taste and adjust seasonings, if necessary.

In a small bowl, mix the sour cream, horseradish, parsley, mint, remaining 2 tsp. dill and remaining 1/2 Tbsp. lemon juice.  Season with salt and pepper and stir to combine.

Cut string from roast and discard.  Slice meat and place on platter.  Drizzle with pan sauce and serve immediately with horseradish cream.
