Instructions

  1. Preheat oven to 425°F. Wash and dry potatoes. Prick potatoes with a fork and microwave on high for 5-7 minutes until tender. Alternatively, bake in oven for 40 minutes.
  2. Meanwhile, trim woody ends from asparagus. Cut lemon into wedges. Finely chop shallot. Coarsely crush tricolor peppercorns using a mortar and pestle or the bottom of a pan.
  3. Pat duck breasts dry with paper towels. Score the skin in a crosshatch pattern, being careful not to cut into the meat. Season both sides generously with salt and black pepper.
  4. Place duck breasts skin-side down in a cold skillet. Turn heat to medium-high and cook until skin is deep golden and crispy, about 6-8 minutes. Flip and cook 2-3 minutes more for medium-rare (or longer to desired doneness). Transfer duck to a plate, leaving rendered fat in the skillet.
  5. While duck rests, add shallot to the skillet and cook over medium heat until softened, about 1 minute. Add crushed peppercorns and cook 30 seconds. Stir in chicken demi-glace and ¼ cup water. Simmer until slightly thickened, 2-3 minutes. Remove from heat and swirl in 1 tablespoon black truffle butter until melted. Season with salt to taste.
  6. Place asparagus on a baking sheet, drizzle with olive oil and squeeze lemon wedges over top. Season with salt and pepper. Roast in oven until tender, 8-10 minutes.
  7. Mash the cooked potatoes with sour cream and remaining 1 tablespoon black truffle butter. Season with salt and pepper to taste.
  8. Slice duck breasts against the grain. Serve with mashed potatoes, roasted asparagus and drizzle peppercorn sauce over the duck.

Recipe Tips

For extra crispy skin, score the duck and start in a cold pan.

Let duck rest 5 minutes before slicing to keep juices inside.

If you can’t find tricolor peppercorns, use black peppercorns alone.

FAQ

Can I use chicken instead of duck?

Yes, but adjust cooking time. Chicken breasts should be cooked to 165°F internal temperature.

What can I substitute for black truffle butter?

Regular butter mixed with a few drops of truffle oil or simply use plain butter.

How do I store leftovers?

Store in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet.
