Instructions

  1. Adjust rack to middle position and preheat oven to 425°F. Wash and dry produce. Dice potatoes into ½-inch pieces. Place in a medium pot with enough salted water to cover by 2 inches. Bring to a boil and cook until tender, 10-15 minutes. Reserve ½ cup potato cooking liquid, then drain. Return potatoes to pot and cover to keep warm. (You’ll finish the potatoes in Step 5.)
  2. While potatoes cook, heat a drizzle of oil in a large pan over medium-high heat. Add prosciutto in a single layer; cook until browned and crispy, 2-3 minutes per side. TIP: If prosciutto starts to brown too quickly, reduce heat to medium. Turn off heat; transfer prosciutto to a paper-towel-lined plate. Wipe out pan.
  3. Trim and discard woody bottom ends from asparagus. Halve, peel and mince half the shallot (all for 4 servings). Finely chop chives.
  4. Pat chicken dry with paper towels; season all over with half the herbes de Provence (all for 4 servings), salt and pepper. Heat a drizzle of oil in pan used for prosciutto over high heat. Add chicken and sear until golden brown, 2 minutes per side. Turn off heat; transfer chicken to one side of a baking sheet. Wipe out pan and let cool slightly. Toss asparagus on empty side of sheet with a drizzle of oil, salt and pepper. Roast on middle rack until chicken is cooked through and asparagus is tender and lightly browned, 12-14 minutes. Transfer chicken to a cutting board.
  5. To pot with potatoes, add sour cream and 2 TBSP butter (4 TBSP for 4 servings); mash until smooth, adding splashes of reserved potato cooking liquid as needed. Taste and season with salt and pepper if desired. Heat 1 TBSP butter (2 TBSP for 4) and a drizzle of oil in pan used for chicken over medium heat. Add minced shallot and cook, stirring occasionally, until fragrant, 1-2 minutes. Reduce heat to low and whisk in ¼ cup water (½ cup for 4), jam and demi-glace. Bring to a simmer, then cook, whisking constantly, until slightly thickened, 1-2 minutes more.
  6. Slice chicken crosswise. Divide chicken, asparagus and mashed potatoes between plates. Spoon pan sauce over chicken and crumble prosciutto over potatoes. Garnish everything with chives and serve.

Recipe Tips

For extra crispy prosciutto, cook it over medium-high heat but reduce heat if it browns too quickly.

Reserve more potato cooking liquid than you think you’ll need; it’s great for adjusting mashed potato consistency.

Let the chicken rest for a few minutes after roasting before slicing to keep it juicy.

FAQ

Can I use dried herbs instead of Herbes de Provence?

Yes, you can substitute with a mix of dried thyme, rosemary, marjoram and lavender if available or just use Italian seasoning.

What can I substitute for fig jam?

You can use any fruit jam like apricot or raspberry or even a tablespoon of honey mixed with a splash of balsamic vinegar.

Can I prepare this dish ahead of time?

The mashed potatoes can be made a day ahead and reheated with a splash of milk. The chicken and asparagus are best served fresh, but leftovers can be reheated in the oven.
