This easy Whole Chicken au Poivre recipe roasts a spatchcock chicken and baby potatoes in a creamy peppercorn sauce with garlic, shallots, rosemary, thyme, and sherry. It's a cozy, one-pan dinner that's naturally gluten-free!
Place the chicken breast-side down on a large cutting board and remove the giblets. Using kitchen shears, cut along the backbone until the chicken is fully open.
Flip the chicken breast-side up and press firmly on the breastbone until it flattens. Pat dry with paper towels.
Place the chicken breast-side up on a large rimmed baking tray. Drizzle with the olive oil and rub ¾ teaspoon salt evenly over the chicken.
Roast for 15 minutes.
While the chicken roasts, combine the heavy cream, paprika, remaining ¾ teaspoon salt, cracked peppercorns, garlic, rosemary, thyme, shallots, and sherry cooking wine in a large bowl. Let sit at room temperature.
Remove the chicken from the oven. Arrange the baby potatoes around the chicken and pour the au poivre cream over and around everything.
Return to the oven and roast for about 45 minutes, basting the chicken with the pan sauce every 15 minutes, until the chicken reaches 165°F in the thickest part and the potatoes are fork-tender.
Let the chicken rest for 5–10 minutes before carving. Serve with the potatoes and spoon the sauce over the top.

Use a little less if you prefer a milder sauce.
