What size chicken should I buy?
A 4 to 5 pound chicken is the sweet spot. Smaller cooks faster but can dry out if you overdo it. Bigger takes longer and can brown too much before the inside is ready.
Do I have to spatchcock it?
Nope. This recipe is written for a whole bird, but if you want faster cooking and more crisp skin, spatchcocking works great. Roast at 425°F and start checking temp around 35 to 45 minutes, but plan for 40 to 55 minutes depending on size, pan, and your oven. Check early, then every 5 to 10 minutes.
How do I know it is done?
Use a thermometer. For the breast, you are looking for 160 to 165°F in the thickest part. (USDA guidance is 165°F for poultry.) For the thigh, aim for 175 to 185°F for the best texture. Resting helps everything finish gently and stay juicy.
Why is my skin not crispy?
The usual culprits are moisture and low heat. Pat the chicken very dry, do not skip the oil on the skin, and finish with a higher-heat blast. Also, avoid covering the chicken while it rests. If you baste a lot, the skin will soften, so keep it minimal.
Can I make it dairy-free?
Yes. Swap the butter for olive oil or a dairy-free butter alternative. You will still get great flavor and crispness.
Should I salt ahead?
If you have the time, yes. Season the chicken with the salt and leave it uncovered on a plate in the fridge for 1 to 24 hours. It makes the meat juicier and the skin crispier. If you are cooking right away, no stress, just follow the recipe as written.
