Pat the chicken dry with paper towels, especially around the skin, to ensure crispiness.
Mix together salt, paprika, garlic powder, and black pepper to create a flavorful dry rub.
Rub the spice mixture generously all over the chicken, pressing it into the skin and seasoning the cavity if desired.
If using, stuff garlic cloves and lemon wedges inside the chicken cavity for extra aroma and flavor.
Open the beer can and pour out a small amount of liquid to prevent overflow. Place the can on a stable surface or drip tray.
Brush the chicken skin with oil or melted butter to help achieve a crispy, golden finish.
Carefully lower the chicken onto the beer can, balancing it upright with the legs on the tray and the can supporting the cavity.
Preheat your grill to medium heat or set your oven to 375°F. Place the chicken on the grill grates or in a roasting pan.
Roast the chicken, uncovered, for about 90 minutes, or until the skin is deeply golden and crispy, and the internal temperature reaches 165°F.
Carefully remove the chicken from the heat and let it rest for 10 minutes to allow juices to redistribute.
Carefully detach the chicken from the can, carve, and serve hot, enjoying the crispy skin and juicy meat with smoky flavor.
