Instructions

1. Step 1: Preheat the oven to 275°F. Pat dry the 4 lb whole chicken and rub it all over with 2 tbsp olive oil, 2 tsp salt, 1 tsp black pepper, and 6 minced garlic cloves, making sure to cover inside the cavity as well. Squeeze juice from 1 lemon half over the chicken and place the squeezed halves inside the cavity.
2. Step 2: Toss 3 peeled and chopped carrots, 2 peeled and chopped parsnips, and 4 quartered red potatoes in 2 tbsp olive oil, 2 tsp salt, and 2 tbsp chopped fresh rosemary until evenly coated. Spread vegetables evenly around the bottom of a large roasting pan.
3. Step 3: Place the chicken breast side up on a rack over the vegetables and roast in the preheated oven for 3 to 3.5 hours, or until the internal temperature reaches 165°F and the skin is lightly browned but not crisped.
4. Step 4: In the last 15 minutes, squeeze juice from the remaining lemon half over the vegetables and chicken for a bright finish. Remove from oven and let rest for 15 minutes before carving and serving with the roasted vegetables.
