Ingredients
Method
- Mix the jar. Combine everything in a bowl, breaking up any lumps of brown sugar with your fingers so it blends evenly. Pour into a sealed jar and shake for 20 seconds. Double-check the box says baking powder, not baking soda — soda in this amount tastes soapy and metallic.
- Dry the chicken hard. Pat every surface completely dry with paper towels, and get inside the cavity of a whole bird. Wet skin steams; dry skin crisps. This step matters as much as the rub itself.
- Season, and get under the skin. Use about 1 to 1½ teaspoons of rub per pound of chicken. Coat all the outer skin, and where you can — on a whole bird or bone-in thighs — gently loosen the skin and work a little rub directly onto the meat underneath.
- Rest it uncovered (the crispy-skin payoff). Set the chicken skin-side up on a rack over a sheet pan and refrigerate uncovered for 4 to 24 hours. This is where the baking powder and salt pull moisture out and tighten the skin. You can skip it in a pinch, but an overnight rest is the difference between good skin and great skin.
- Cook it hot. Roast, grill over indirect heat, or air-fry. For bone-in parts, cook at 425°F until the thickest part of the thigh hits 175°F; a whole bird runs about 45–60 minutes at 425°F depending on size. The skin should come out deep golden and crisp — no oil needed.
- Store the rest. Keep it in an airtight jar in a cool, dark cupboard away from the stove. Give it a shake before each use, since the baking powder and sugar can clump in humid weather. Best within about three months.
Notes
For extra-crispy wings, toss them with the rub plus an additional 1/2 teaspoon of straight baking powder per pound before the fridge rest — it's the classic trick and it works. Cooking over an open flame? Keep the chicken over indirect heat or drop your grill temp, because the brown sugar can scorch over direct fire; for a hard-sear, high-flame cook, leave the sugar out. And because the salt lives in this jar, don't also brine the chicken in salt first or it'll come out too salty — this rub is the seasoning.
