Ingredients:
- 1 whole chicken (about 3.5 lbs / 1.6 kg), patted thoroughly dry
- 2 tablespoons Olive Oil
- 1 teaspoon Kosher Salt
- 1/2 teaspoon freshly ground Black Pepper
- 1 large Yellow Onion, quartered
- 4 large Shallots, peeled and halved lengthwise
- 4 sprigs fresh Thyme
- 2 cloves Garlic, smashed
- 1 cup Dry Ruby Port Wine
- 1 cup good quality Chicken Stock (low sodium)
- 2 tablespoons Unsalted Butter, chilled and cubed
- 1 tablespoon Balsamic Vinegar
Instructions:
- Preheat oven to 400°F (200°C). Season the chicken liberally, inside and out, with salt and pepper. Place the onion quarters, shallots, thyme, and garlic inside the cavity.
- Heat olive oil in a large oven-safe Dutch oven over medium-high heat. Sear the chicken breast-side down first until deeply golden brown (about 5-7 minutes). Flip and sear the back for 3 minutes. Remove chicken and set aside.
- Add a splash of Port to the hot pan to lift any browned bits (the fond). Add any remaining shallots and onions and sauté briefly until softened.
- Return the chicken to the pot, breast-side up. Pour the remaining Port wine around the chicken (not over the skin). Bring to a gentle simmer on the stovetop.
- Cover the Dutch oven and transfer to the preheated oven. Roast for 45 minutes.
- Remove the lid. Lower the oven temperature to 375°F (190°C). Continue roasting for another 30-45 minutes, basting occasionally, until the internal temperature in the thickest part of the thigh reads 165°F (74°C).
- Remove the chicken from the pot and let it rest tented loosely with foil for at least 15 minutes.
- Strain the pan juices into a small saucepan, discarding the cooked aromatics. Add the chicken stock. Bring to a rolling simmer over medium heat and reduce by about one-third until it coats the back of a spoon (nappé stage).
- Remove the sauce from the heat. Whisk in the chilled butter, one cube at a time, to emulsify and enrich the sauce (monter au beurre). Stir in the balsamic vinegar, if using. Taste and adjust seasoning.
- Carve the chicken and drizzle generously with the Port reduction sauce. Serve immediately with creamy mashed potatoes.
