1-First, remove the giblets from the 4-5 lb whole chicken and let it reach room temperature for even cooking. Pat the chicken dry with paper towels to remove any moisture, then spray or drizzle it with the 2 teaspoons of cooking oil. This helps the seasonings stick and keeps the skin crisp.

2-Next, season all sides of the chicken, including the cavity, with the 3 tablespoons of salt, pepper, and garlic powder. If you choose, apply the optional 1/4 cup of BBQ rub evenly for added zest. Truss the legs with kitchen twine and tuck the wing tips behind the back to ensure even smoking.

3-Preheat your smoker to 275°F (135°C) and place the chicken breast-side up on the grate. Smoke for about 2 hours, spraying with oil or butter after 45 minutes and again after 1.5 hours while rotating as needed. Keep an eye on it to maintain that perfect smoky flavor.

4-Use a meat thermometer to check when the internal temperature hits 165°F (74°C) in the breast and 175°F (79°C) in the thigh for safety and juiciness. Once done, let the chicken rest for 20 minutes before carving so the juices spread out evenly. This step makes a big difference in the final texture.
