What you’ll learn

  1. The bird in the bagPick a young broiler-size chicken, name the breast-versus-leg problem, and scale Kenji's four-plate roast.Buy a broiler-fryer or small roaster, not a stew hen. Breast dries near 150°F. Legs want more heat for collagen. An adult owns the raw bird. You measure.
  2. Salt, not waterSkip the sink wash, pat the skin dry, dry-brine with kosher salt, and explain why uncovered fridge air and a pinch of baking powder help browning.CDC and USDA: do not wash raw chicken. Towels, then salt, then an uncovered rest. Wet skin steams. Baking powder is a skin trick that speeds Maillard.
  3. Flatten the birdSpatchcock with shears, park breasts in the pan's cool middle and legs at the hot edge, and keep herbs under the skin.Wet brine and trussing are Band-Aids. Flattening uses the sheet pan's unfair heat. Adult shears. Wings tucked. Backbone saved for jus.
  4. Heat, brown, 165Roast a flat bird at 450°F, oil the skin once, and confirm 165°F in thigh, wing, and breast before a five-minute rest.Hot oven, no watery basting. USDA 165°F is tonight's floor. Kenji's 150/170 talk is texture science. Three spots, no bone. Loose foil, five minutes.
  5. Carve, leftover, next birdCarve the flat bird, make backbone jus, refrigerate leftovers within two hours, and troubleshoot the next roast.Breasts, then legs. Jus from the back, lemon, soy, butter. USDA two-hour clock and 3 to 4 days in the fridge. Pale skin is wet skin. Color is not doneness.

Questions this course answers

Why does Kenji butterfly, or spatchcock, a roast chicken?

Kenji uses the unfair heat of a sheet pan on purpose: legs at the hot edge, breast in the cooler center, so dark meat can go further without turning the breast to cardboard.

In your own words, why is washing a raw chicken in the sink a bad idea?

CDC: raw chicken is ready to cook and does not need washing. Splash spreads Campylobacter and Salmonella. Heat, not a tap, is the kill step.

Match each move to the job it does on the bird

Salt seasons and buffers. Dry air crisps. Baking powder is a skin trick, not a cake trick. Oil is fat. Drippings are water.

Put Kenji's first roast chicken in the order that keeps skin dry and both meats cooked

Shape and dry first. Salt next. Heat third. Rest and the leftover clock last. Wash never makes the list.

USDA says to check a whole bird in three places. Which list is that?

USDA food-thermometer guidance: innermost thigh, innermost wing, thickest breast. Bone, fat, and gristle lie.

Kenji will not baste a roast chicken with pan drippings. Why?

Kenji and Gritzer: watery drippings (and whole butter) wet the skin. Oil once. Opening the door to baste also dumps oven heat.
