Remove chicken from packaging. Remove giblets from cavity. Rinse briefly under cold water and pat COMPLETELY dry with paper towels—inside and out. In small bowl, mix 2 tablespoons kosher salt, 1 tablespoon black pepper, 1 tablespoon garlic powder, 1 tablespoon smoked paprika, and 1 tablespoon cornstarch. This is your dry brine and dehydration mixture. Cornstarch is one of key Crispy Grilled Chicken Secrets—it pulls moisture from skin and creates crispy coating. Rub mixture all over chicken—under skin (gently loosen skin over breast and thighs), inside cavity, and all over exterior. Stuff cavity with lemon halves and fresh herbs (rosemary, thyme). Place chicken on wire rack set over rimmed baking sheet. Refrigerate UNCOVERED for 12-24 hours. Circulating cold air will dehydrate skin, forming pellicle. Longer you leave it (up to 24 hours), crispier skin will be.

Two-zone method is one of most critical Crispy Grilled Chicken Secrets. It allows gentle cooking over indirect heat, then high-heat sear over direct flames. FOR CHARCOAL: Fill chimney starter with Kingsford Charcoal and light. Wait until coals covered with white ash (15-20 minutes). Pour all hot coals onto ONE SIDE of grill, leaving other side empty. This creates hot zone (direct heat) and cool zone (indirect heat). Add 2-3 chunks applewood or cherry wood on top of coals for smoke. Place grill grate on and preheat 5 minutes. Scrub clean with grill brush. FOR GAS: Light burners on one side only. Leave other side off. This creates same two-zone setup.

Remove chicken from refrigerator 30 minutes before grilling to bring closer to room temperature. This ensures even cooking—cold chicken cooks unevenly with outside overcooking before inside reaches safe temp. Brush skin lightly with olive oil or melted butter—this aids browning and Maillard reaction.

Place chicken BREAST-SIDE DOWN on INDIRECT HEAT side (side without coals or with burners off). Close lid. Maintain grill temperature 350°F-375°F (177°C-190°C). Use grill's built-in thermometer or insert probe thermometer through vent. Cook 45-60 minutes depending on size. Do NOT open lid frequently—every time you open, you lose heat. After 45 minutes, check internal temperature by inserting instant-read thermometer into thickest part of THIGH (without touching bone). Look for 155°F-160°F (68°C-71°C) at this stage.

Once chicken reaches 155°F-160°F internally, time to crisp skin. This is where final Crispy Grilled Chicken Secrets come into play. Carefully flip chicken BREAST-SIDE UP. Move to DIRECT HEAT side (over hot coals or lit burners). Close lid for 5-8 minutes. You'll hear fat sizzle and see flare-ups as drippings hit coals—this is good. Flames create char and smoky flavor. Watch carefully to prevent burning. If flames too aggressive, move chicken slightly to side. Skin should darken, blister slightly, become deeply golden brown with visible cross-hatch grill marks. Internal temperature will rise to 165°F (74°C) during final sear.

Remove chicken from grill when thigh reaches 165°F (74°C). Transfer to cutting board and tent loosely with aluminum foil. Let rest 10-15 minutes. During rest, carryover cooking brings temperature up another 5°F, and juices redistribute throughout meat. When you carve, chicken will be moist, not dry. Skin will remain crispy because you properly dehydrated during air-dry phase. If you skip that step, skin softens during rest. Carve and serve immediately while skin is still crackling.
