- 1 1/4 pounds winter squash, peeled, seeded and cut into chunks
- 1 pound fingerling potatoes, split lengthwise
- 1/2 pound carrots, split lengthwise and cut into 2-inch pieces
- 2 tablespoons extra-virgin olive oil
- salt and ground black pepper to taste
- 1 (3 pound) whole chicken, giblets removed
- 1/2 cup butter, divided
- 1 stalk celery, leaves removed
- Preheat oven to 425 degrees F (218 degrees C).
- Toss squash, potatoes, carrots, olive oil, salt, and pepper in a roasting pan. Spread into a single layer and place a V-rack on top. Season chicken generously inside and out with salt and pepper. Place 1 tablespoon butter in the chicken cavity. Arrange dollops of remaining butter between skin and flesh of breast meat. Cut celery into 3 or 4 pieces and place in cavity of chicken.
- Bake in preheated oven for 30 minutes. Turn heat down to 375 degrees F (190 degrees C) and continue baking until no longer pink at the bone and juices run clear, about 30 minutes. An instant-read thermometer inserted into the thickest part of the thigh, near the bone should read 165 degrees F (74 degrees C). Remove the chicken from the oven, cover with a doubled sheet of aluminum foil, and allow to rest in a warm area for 10 minutes before slicing.
