Instructions

  • Preheat oven to 425°F while you butterfly the chicken using kitchen shears to remove the backbone, pressing it flat for even cooking.
  • Rub chicken all over with salt, pepper, oregano, parsley, rosemary, and sage.
  • Place chicken breast side up in a roasting pan. Add sliced shallots and garlic cloves beneath and around the bird.
  • Brush with melted butter, reserving some for basting.
  • Roast uncovered for 45-55 minutes, basting halfway through with reserved butter.
  • Check internal temperature reaches 165°F. Let rest 10 minutes after roasting.
  • For the sauce, deglaze the roasting pan with white wine, add Dijon mustard, and simmer to reduce.
  • Roast a garlic head wrapped in foil at 400°F for 30 minutes until soft.
  • Boil peeled, cubed potatoes until tender.
  • Mash potatoes with butter, cream, roasted garlic, and chives until creamy.
  • Carve rested chicken and serve over mashed potatoes.
  • Drizzle wine mustard sauce over everything and enjoy.

Notes

Make-ahead tips: butterfly and season chicken the day before; use garlic paste when in a rush. Mashed potatoes warm nicely in a slow cooker. Store leftovers up to 4 days.
