💡 Pro Tip: Spatchcocking (butterflying) reduces cooking time by roughly 25–30% compared to a whole roast chicken. Always use a meat thermometer to confirm the internal temperature reaches 165°F (74°C) at the thickest part of the thigh — not touching bone.

⏱️ Temperature Conversion: To convert Celsius to Fahrenheit: multiply by 9, divide by 5, then add 32. Example: 220°C × 9 / 5 + 32 = 428°F. Note: Fan-assisted ovens typically run 20°C (35°F) hotter — reduce your set temperature accordingly.

Spatchcock is a nice name for a pretty simple cooking method. The word comes from an old Irish saying about “dispatch the bird”. It is made up of removing the spine of chicken, so that it cooks flat.

How to Spatchcock a Chicken

Some folks call it also butterflying. After the spine is gone and the bird is pressed, it cooks in one layer. Like this one gets faster and even roasting with crisp skin always.

To spatchcock chicken, put the bird on a cutting board, belly down, with legs facing to you. With good kitchen shears, cut through meat and bones along both sides of the spine. Then press hard on the breastbone until you hear a popping sound.

That is the cracking of the middle bone, and the chicken now should lie almost flat. Some methods include removing the bone with a separate knife after that.

It does not need special tools or a pro. A pair of kitchen scissors or good knife at home is enough. The first cutting can seem messy, but the whole process is easy and truly worth the effort.

Using a whole bird is better, because whole chickens usually cost less per pound than parts especially. Also, one can enjoy both white and dark meat from one bird. When the chicken lies flat, all skin is up.

So it gets equal heat and crisps nicely, rather than when part sits in fat juice at the pan edge.

Spatchcocking halves the cooking time compared to usual roasting of a whole bird. The main meal reaches the table more soon. Legs and chests cook evenly and end at the same time.

So one has juicy meat inside and really crisp skin outside.

Do not roast spatchcocked chicken at low and slow temperature. The meat dries out, and the skin becomes rubbery. So rubbing the skin with melted butter or olive oil helps a lot.

Dry spice, Cajun mix or even BBQ sauce layer add taste. Wet salt in the fridge is another good trick for ideal roast chickens. The bird can cook above vegetables, witch makes a wonderful one-pan meal.

There are many ways to adapt spatchcockedchicken with various spices, rubs or sauces.
