I've made spatchcock chicken dozens of times, and this cast-iron method never fails. It's my go-to for juicy meat, ultra-crispy skin, and even cooking-every single time. I used to save whole roasted chicken for special occasions, but ever since I started making it this way-in my cast-iron skillet with plenty of garlic herb butter-it's become a regular in my dinner rotation. Whether you're a first-timer or just want to get it right on the first try, I'll walk you through exactly how to make it foolproof.

This Flat-Roasting Method Works
Spatchcocking sounds like one of those cooking techniques that is going to be much more complicated than it actually is. Luckily, it's really just a matter of removing the backbone and pressing the chicken flat. And there is a good reason to do it. A whole chicken is an awkward shape, so the different parts don't cook at the same rate. The breasts are leaner and tend to cook faster, while the thighs and legs need more time. Flattening the chicken helps everything cook more evenly, so you can get juicy breast meat and tender thighs without waiting forever for dinner.
The flat shape also gives more of the skin a chance to brown and crisp up in the oven. And if you love crispy chicken skin as much as I do, that's reason enough. One important step is making sure you really flatten the chicken. After removing the backbone, flip the chicken over and press firmly on the breastbone with both hands. You should hear a little crack as the breastbone gives way. Don't be afraid to put some weight behind it. The chicken should lie fairly flat in the skillet when you're finished. You'll never make a whole chicken the same way again.
Key Ingredients
- Whole chicken (4-5 lbs). The star of the dish. A smaller 3-4 lb bird works too; just start checking the temperature around the 40-minute mark since it will cook faster.
- Unsalted butter, softened. Carries the garlic and herb flavor under the skin and helps it crisp. If you're dairy-free, swap in softened ghee or olive oil; the skin will be a shade less golden but still crisps up well.
- Garlic cloves, minced. Sharp raw, but mellows and sweetens as it roasts under the skin.
- Lemon zest and juice. Zest the lemon before you juice it. For a milder, slightly sweeter flavor, swap in orange zest.
- Fresh herbs (parsley, rosemary, thyme). if you don't have fresh on hand, use 1 tablespoon of dried herbs total (about a third of the fresh amount) and add an extra pinch of lemon zest to make up for the brightness dried herbs lack.
- Onion. Props the chicken up off the bottom of the skillet so the skin doesn't steam, and flavors the pan drippings. Halved lemons or a bed of hearty root vegetables work as a substitute if you want to skip the onion.
See the recipe card below for the remaining ingredients and quantities.
Instructions
Step 1
Preheat the oven to 375°F. Remove the giblets from inside the cavity and trim any excess fat, skin, or leftover feathers. Pat the chicken dry thoroughly with paper towels. Place the chicken on a flat, sturdy surface with the backbone facing up. Use kitchen shears or a sharp knife to cut along both sides of the backbone and remove it.
Step 2
Flip the chicken over so the breasts are facing up. Place your fingers underneath the breasts with your thumbs on top, then press down firmly with your thumbs while pulling out slightly with your fingers. You should hear a crack-this means the chicken is now flattened and ready to roast.

Step 3
In a bowl, mix together the butter, garlic, lemon zest, lemon juice, salt, black pepper, and herbs until well combined.
Step 4
Gently loosen the skin from the meat and rub the herb butter underneath. Spread the remaining butter over the top of the chicken skin.
Step 5
Place the onion at the bottom of a cast-iron skillet or oven-safe baking dish, then lay the chicken on top. Drizzle the skin with a little oil for extra color and crispiness.
Step 6
Roast the chicken on the middle rack for 30 minutes. Baste with the juices from the pan, then return it to the oven and roast for another 20-30 minutes, or until the internal temperature reaches 165°F.
Step 7
Remove the chicken from the oven and let it rest for 10-15 minutes before carving.
How to Spatchcock a Chicken (Video Tutorial)
Sarah's Top Tips
- Dry the chicken thoroughly before you do anything else. I pat mine down with paper towels for a full minute, including under the wings and around the legs. Any surface moisture turns to steam in the oven, and steam is the enemy of crispy skin. This one step matters more than any amount of butter on top.
- Baste at the halfway point, not before. I tested this both ways, basting from the start versus waiting until the 30-minute mark, and basting too early washes away the seasoning before it has a chance to form a crust. Wait until the butter and pan juices have started to caramelize, then spoon them over the skin.
- Tuck the wings. Tuck the wing tips underneath the bird before it goes in the oven so they don't scorch, and always confirm doneness with a meat thermometer in the thickest part of the thigh (165°F) rather than trusting the clock. Ovens run differently, and a thermometer is the only way to know for sure.
Serving Suggestions
I love serving this spatchcock chicken with simple sides that let the crispy skin and herb butter shine. Think air fryer frozen brussels sprouts or a bright lemony arugula salad to balance it all out. If I'm feeling fancy, I'll drizzle the pan juices over everything-it's too good not to.
I always make this when I know I'll need leftovers to hold me over for a few days. I shred the extra chicken for sandwiches, toss it into soups, or make a quick apple chicken salad for lunch the next day. It's one of those meals that feels special but works just as well for meal prep.
Storage & Reheating
Fridge: Place any cooled chicken in an airtight container and store it in the fridge for up to 4 days.
Freezer: For longer storage, freeze individual pieces for up to 3 months-I like to wrap them in foil first, then pop them in a freezer bag.
Reheating: When you're ready to reheat, I recommend warming it in a 350°F oven or a covered skillet on the stovetop with a splash of broth or pan juices to keep it moist. Skip the microwave if you can-it tends to dry out that perfectly roasted chicken.

Ingredients
- 4-5 pound uncooked whole chicken
- ⅓ cup unsalted butter, softened
- 3 garlic cloves, minced
- 2 tablespoons lemon zest
- 1 tablespoon lemon juice
- 1 ½-2 teaspoons salt
- 1 teaspoon black pepper
- ¼ cup fresh chopped herbs, parsley, rosemary, thyme, etc.
- 1 large onion cut into quarters
- Olive oil or avocado oil
Instructions
- Preheat the oven to 375 degrees F. Remove the giblets from inside the cavity and remove any excess fat, skin, and leftover feathers. Pat the chicken dry with paper towels.4-5 pound uncooked whole chicken
- Place the chicken on a flat, sturdy surface. The backbone should be facing up towards you. Use kitchen shears or a sharp knife to cut carefully along each side of the backbone.
- When the backbone is removed, flip the chicken over so the breasts are facing up. Grab underneath the breasts with your fingers so your thumbs are still on the breasts. Push down with your thumbs at the same time you pull out with your fingers. You should hear the bone crack, and the chicken should now lie flat. (see notes below if you need help with this)

- Using your hands, season the chicken between the skin and the meat with the herb butter, and then use the remaining butter to cover the top of the skin.
- Place the onion at the bottom of your cast iron skillet or baking dish, and place the chicken on top. I like to drizzle the skin with a little oil before placing it in the oven to give it a little more color.1 large onion cut into quarters, Olive oil or avocado oil

Sarah's Tips
- Pat the chicken drier than feels necessary, and make sure the oven is fully preheated before the skillet goes in. Surface moisture and a cold oven are the two most common reasons the skin doesn't crisp up.
- Don't roast a partially frozen bird. It cooks unevenly and the breastbone won't release cleanly during flattening, so thaw it completely in the fridge first (about 24 hours per 4 to 5 pounds).
- For more heat, add a half teaspoon of red pepper flakes or cayenne to the herb butter. The lemon and herbs balance heat well, so you can go heavier than you'd expect.
- If you're watching sodium, cut the butter's salt to 1 teaspoon and season the cavity lightly instead. You'll lose a little crust flavor but keep the same juicy texture.
- No cast iron skillet? A heavy oven-safe skillet or a rimmed sheet pan both work. The cast iron mainly gives a head start on browning, so a sheet pan version will still be delicious, just slightly less crisp on the bottom.

Haven't cooked a whole chicken in many years, but will make this again! Rec'd a 5 lb. chix and decided to spatchcock and cook in 10" cast iron frying pan. At 85 y/o I had never spatchcocked a chicken before; it was so easy to do. I marinated it overnight; let it come to room temp; patted it completely dry and roasted as directed. I cooked a lemon rice casserole next to it in the oven. Chicken was moist and delicious. The drippings over the rice fantastic. My picky family really enjoyed.
