Spatchcocked, miso-butter rubbed, dry-brined overnight, roasted high. The cooked-miso execution at full volume.
Most miso roast chicken recipes I’ve read miss the same two things. They use the wrong miso. And they don’t give the bird enough heat.
This recipe is the fix for both. A shinshu base — balanced, neutral, reliable — with a single spoon of red miso stirred in for depth. Smeared into softened butter. Worked under the skin. Dry-brined uncovered in the fridge for 18 to 24 hours, which dries the skin the way Chinese roast ducks dry the skin, so it can actually crisp. Then roasted at 425°F — not 375, not 400, because at those temperatures the miso’s sugars never caramelize and the skin pulls out the oven beige and sad. At 425°F the miso-butter Maillards on the bird and the whole skin goes bronze and lacquered, and the breast stays juicy because the spatchcock cuts the cook time short enough that it doesn’t have time to dry out.
Two structural rules before we start, because they are the recipe:
Spatchcock the bird. Remove the backbone, press the breast flat. Flat-birds cook faster and more evenly than upright ones. A whole-roasted chicken is charming. A spatchcocked chicken is better. I’ll take better over charming every time.
Dry-brine uncovered in the fridge, overnight minimum. The salt in the miso pulls moisture out of the skin, pulls it back in seasoned through osmosis, and leaves the surface dry and primed for crisping. Skip this step and the miso-butter slides around on a wet skin and the whole thing steams instead of roasts. Don’t skip this step.
