Instructions
Begin by preheating your oven to a steady 350 degrees F (175 degrees C), ensuring it's at the perfect temperature for even roasting. In a spacious roasting dish, combine 1 cup of water with the chopped onion, 5 tablespoons of rich olive oil, and 2 tablespoons of tangy balsamic vinegar. Stir in the smooth Dijon mustard, the pungent aroma of crushed garlic cloves, and the warming spices of black and cayenne pepper. Season generously with salt to taste. This vibrant mixture will be the heart of your marinade. Add the whole chicken to this flavorful bath, carefully turning it over so every inch is luxuriously coated with the aromatic sauce. Let the chicken absorb these flavors before placing it in the oven. Roast the chicken in the preheated oven, allowing it to cook slowly and evenly. Roast until an instant-read thermometer inserted into the thickest part of the thigh near the bone registers 165 degrees F (74 degrees C), which should take about 1 hour and 30 minutes. This ensures the chicken is perfectly cooked, juicy, and tender. For best results, baste the chicken occasionally with the pan juices to enhance moisture and flavor. Once cooked, let the chicken rest for a few minutes before carving to allow the juices to redistribute, resulting in a succulent and satisfying meal.
