Preheat your oven to 425°F and pat the whole chicken dry inside and out with paper towels. This crucial step ensures crispy, golden skin that crackles beautifully when you slice into it.
Combine minced garlic, fresh rosemary, fresh thyme, Dijon mustard, paprika, salt, and pepper in a small bowl. Rub this herb mixture generously all over the chicken, inside the cavity and under the skin for maximum flavor distribution throughout the roasted chicken.
Halve two of the lemons and stuff them inside the cavity along with the quartered onion. Pierce the remaining two lemons with a fork and place them around the chicken in your roasting pan.
Place the cozy lemon roasted whole chicken recipe on a bed of baby potatoes and baby carrots in a large roasting pan. Roast at 425°F for 20 minutes, then reduce heat to 375°F and continue roasting for 50-55 minutes until the internal temperature reaches 165°F at the thickest part of the thigh.
Drizzle the vegetables with olive oil, salt, and pepper before adding them to the pan. Halfway through cooking, brush the chicken with honey mixed with the pan juices for a gorgeous caramelized finish.
Remove the pan from the oven when the chicken reaches temperature and the skin is deeply golden. Let it rest for 10 minutes—this allows the juices to redistribute, keeping the meat incredibly tender and moist.
Pour the chicken broth into the pan to create a silky pan sauce that's perfect for spooning over everything. Transfer the chicken and vegetables to a serving platter and drizzle generously with this flavorful sauce.
