Instructions

  1. Preheat oven to 400°F. Wash and dry all produce. Peel and dice sweet potatoes into 1-inch cubes. Trim woody ends from asparagus. Finely chop chives. Crack tricolor peppercorns in a mortar and pestle or place in a bag and crush with a heavy pan.
  2. Place sweet potatoes in a medium pot and cover with salted water. Bring to a boil and cook until fork-tender, about 15-20 minutes. Drain and return to pot. Mash with sour cream, 1 tablespoon butter, salt and black pepper to taste. Cover to keep warm.
  3. While potatoes cook, season beef tenderloin steaks all over with salt. Press the cracked peppercorns onto both sides of the steaks to form a crust. Heat 1 teaspoon cooking oil in a large oven-safe skillet over medium-high heat. Sear steaks for 2-3 minutes per side, until golden brown. Transfer skillet to the oven and roast to desired doneness (about 5-7 minutes for medium-rare). Remove from oven, transfer steaks to a plate and tent with foil. Let rest 5 minutes.
  4. In the same skillet (wipe out excess oil if needed), add 1 teaspoon cooking oil over medium heat. Add sliced almonds and cook, stirring, until golden, about 1 minute. Add asparagus and cook, tossing, until bright green and tender, 3-4 minutes. Season with salt and black pepper. Remove from heat.
  5. In a small bowl, combine remaining 2 tablespoons butter (softened) with chopped chives. Mix well. Season with a pinch of salt.
  6. Serve the peppercorn-crusted beef tenderloin with a dollop of chive butter on top, alongside the asparagus amandine and mashed sweet potatoes.
  7. For extra flavor, drizzle any accumulated juices from the rested steak over the meat.

Recipe Tips

For even cooking, let the steaks come to room temperature for 20 minutes before searing.

If you don’t have a mortar and pestle, place the peppercorns in a zip-top bag and crush with a rolling pin or heavy skillet.

To make chive butter ahead of time, roll it in plastic wrap into a log and refrigerate. Slice into rounds as needed.
