To butterfly a chicken simply means to remove the backbone so that the bird can lay flat on your cooking surface.
The purported benefits being more exposure of the chicken skin and even cooking of the legs/thighs and the breast meat.
In order to spatchcock or butterfly a chicken, you will need:
*I personally don’t recommend using a knife to butterfly a chicken. Maybe you’re more skilled than I am but I’ve had a few close calls when removing the backbone/going through ribs with a knife.
The first thing I always do is check the inside of the bird for the giblet bag.
The giblet bag contains parts of the chicken that most folks would consider offal – namely the gizzard, mechanical stomach, liver, heart, etc.
Keep in mind: The giblet bag that’s found in your Chicken isn’t from the original Chicken.

Even if you opt to cook the giblets, the bag should be removed to prevent the packaging from melting or being altered. If melted, the packaging can leach harmful chemicals into the surrounding meat.
Similarly, I also remove the pop-up timer if the bird has one in it.
This is as easy as pulling the pop-up timer out of the bird.
Both of these may not be present in your bird. However, they’re pretty common with Roaster chickens (which are around 5+ lbs). With a bird like a fryer or broiler they’re less common (which are around 2 – 4.5 lbs).
The next thing I always do is pat dry the surface of the chicken. Aside from making the chicken easier to work with, it also helps with achieving crispy skin.
The reason for this is because the surface moisture needs to evaporate before browning can happen.
This same concept is true for steak and developing a desirable outer crust.
With chicken something that a lot of people struggle with is achieving:
Pat drying and butterflying can help to address these issues.
Start with the whole chicken so that the breast is facing the cutting board and the backbone is up. The bird should look like this:
I prefer to cut from the tailbone end towards the neck (the side with the drumsticks and thighs).
You then want to use your kitchen shears to cut parallel to the tailbone – both on the left and right of it – to remove the backbone.
I find that alternating between both sides is helpful. Mainly because the ribs keep the backbone straight, which makes cutting easier.
When one side is cut at a time the backbone gets pushed to the side that isn’t cut and you’re left trying to cut on an angle.
Now that the backbone is removed, the inside of the chicken will be exposed and laid open:
Sometimes the inside of the bird will have entrails that I prefer to remove, namely parts of the kidney that are left near the thigh meat.
I find that paper towel works well to take the remnants out.
If they’re giving you a hard time, you can use your knife to scrape them out.
With the inside exposed, I like to do a quick trim of the fat globules and scraggly skin.
Typically the thighs will each have a large piece of fat that extends from them (my bird only had it on one). You can use your hands to tear this fat off and it will cleanly pull away from the thigh.
If it doesn’t, use a sharp knife or kitchen shears to remove it.
Similarly, the breast will typically have scraggly skin and exposed fat near where the neck would of been; Use a sharp knife or your kitchen shears to remove this.
You want enough skin so that it covers each breast; Any excess fat also isn’t necessary and likely won’t render.
The small bit above I trimmed with my kitchen shears.
Here’s the inside of the bird with the excess fat and kidneys removed:
There are two popular methods people use to flatten the chicken.
I personally find that using kitchen shears to break the clavicle (wish bone) is the most consistent. Since we already have the bird facing down, it’s also right there and easy to do.
I first like to make an incision with a sharp knife into the meat. As indicated by the dotted white line:
This helps expose the clavicle so that I can get under it with my kitchen shears.
Just to get a better visual of what this looks like:
We can now flip the bird over to verify that the bird is laying flat and that it’s spatchcocked:
The bird lays flat and is now considered spatchcocked or butterflied.
