# What You'll Need:

→ Tenderloin

01 - 3 pounds beef tenderloin
02 - 1 teaspoon salt
03 - 1 teaspoon pepper
04 - 1 tablespoon olive oil
05 - 3 tablespoons unsalted butter, melted
06 - 2 tablespoons balsamic vinegar
07 - 1 teaspoon Dijon mustard

10 - ½ cup Greek yogurt
11 - ¼ cup sour cream
12 - 2 tablespoons lemon juice
13 - 2 teaspoons horseradish
14 - ¼ teaspoon salt or to taste

# Step-by-Step Directions:

01 - If necessary, trim the silver skin and tie the tenderloin properly with kitchen twine. Season the beef generously with 1 teaspoon of salt and 1 teaspoon pepper.
02 - Preheat oven to 450°F (232°C).
03 - Heat the olive oil in a large oven-safe skillet and sear the tenderloin on all sides until evenly browned.
04 - In a small bowl combine the melted butter, balsamic vinegar, Dijon mustard, minced garlic, and thyme. Brush the glaze over the tenderloin, ensuring all sides are evenly covered.
05 - Place the skillet into the oven and roast for about 25 minutes for medium-rare or until a meat thermometer inserted into the thickest part reads 130°F (54°C).
06 - Meanwhile, in a small bowl mix together Greek yogurt, sour cream, lemon juice, horseradish, and salt. Chill until ready to serve.
07 - Remove the tenderloin from the oven and transfer to a cutting board. Cover with aluminum foil and let rest for 10 minutes. Slice and serve with the yogurt sauce.

# Helpful Notes:

01 - A thermometer is the ONLY way to guarantee a perfectly cooked beef tenderloin just how you like it. 120°F to 125°F: rare; 130°F to 135°F: medium-rare; 140°F to 145°F: medium; 150°F: well done.
02 - Beef tenderloin will last in the refrigerator for 3-4 days when stored properly in an airtight container.
03 - To extend its shelf life, store properly in the freezer where it will last up to 3 months. Thaw in the refrigerator overnight before reheating.
