A chicken breast is thick at one end and thin at the other, and no pan can fix that. By the time the thick end is cooked through, the thin end is dry. Butterflying is the cut that solves it.
You are opening the breast like a book: one horizontal cut through the thick side that stops just short of the far edge, so the two halves stay hinged. The result is a piece of even thickness that cooks in half the time.
This guide covers the hand position that keeps you safe, where to start the cut, when to butterfly versus cutting two separate cutlets, and whether you still need to pound it afterward.
What You'll Need
- A sharp chef's knife: Long enough to cross the breast in one draw, sharp enough that it slices rather than pushes. A dull knife tears chicken into a ragged surface.
- A board that will not move: Your knife is travelling horizontally with your flat hand on top of the meat, so a board that slides puts your palm in the path of the blade. A ROO Mat grips smooth counters so the board stays anchored, and it is top-rack dishwasher safe for raw poultry work.
- Plastic wrap and a mallet: For evening out the thickness afterward, if the piece is still uneven.
- Paper towels: Patting the breast dry gives your guiding hand grip on a very slippery surface.
How to Butterfly a Chicken Breast, Step by Step
Chill it and pat it dry
Work with the breast cold from the fridge and blot the surface dry. Cold firm meat cuts cleanly, and a dry surface is one your flat hand can actually hold still.
Trim the tenderloin and any fat
Pull off the loose tenderloin strip on the underside if it is still attached and save it, it cooks faster than the breast. Trim any fat or gristle at the thick end.
Set it thick side toward your knife
Lay the breast flat and smooth side up, with the thick end facing your knife hand and the tapered end pointing away. You cut into the thick side, never the thin one.
Flatten your guiding hand on top
Lay your palm flat on the breast to hold it down, fingers spread and flat, well above the plane of the blade. This is the one cut where the claw grip is wrong, because the knife is travelling horizontally.
Cut horizontally into the thick side
Hold the knife parallel to the board and slice into the thick edge at its midpoint, working slowly toward the far side with long draws rather than short saws.
Stop about half an inch from the far edge
Do not cut all the way through. That last half inch is the hinge. Feel for it with your free hand and stop before the blade breaks the far side.
Open it like a book
Fold the top half back and the breast lies flat as one thin, even piece roughly double the original width.
Even it out with a few taps if needed
Lay plastic wrap over it and give the thicker areas a few light taps with a mallet or the base of a pan. You are levelling, not tenderizing, so tap rather than hammer.

ROO is a silicone mat that sits under your cutting board. It grips smooth countertops so the board never slides, and its built-in 7-cup pouch catches peels and trimmings as you cut. The Bundle includes the mat, a rubberwood board, and a reusable storage bag. $54.99.

There is nothing to open there and the knife exits immediately. Always start on the thick side.
The claw grip protects your fingertips from a vertical blade. Here the blade is horizontal, so you want a flat palm held high above the cutting plane.
It is a mild mistake, not a disaster. You get two cutlets. If you wanted a hinge for stuffing, go slower and feel for the far edge.
Room-temperature breast is soft and squirms under the knife. Cold from the fridge is far easier to control.
Pounding alone can even out a thin breast, but a thick one turns to mush before it flattens. Cut first, then tap lightly to finish.
Upgrade Your Prep Workflow: The ROO Bundle
Butterflying is the one cut where a moving board is genuinely dangerous, because the blade travels horizontally with your flat hand pressed on top of the meat. The ROO Mat sits under the board and grips smooth countertops so nothing shifts mid-draw, and the 7-cup pouch takes the trimmed fat and gristle off the board instead of leaving raw scraps beside the meat. The mat is top-rack dishwasher safe, and the Bundle includes a 13.75" x 9.75" rubberwood board and a reusable storage bag.

A horizontal cut needs a board that cannot slide.

Frequently Asked Questions
Is it better to butterfly a chicken breast or pound it?
Butterfly first for anything thick. Pounding alone shreds the fibers of a thick breast before it flattens. A few light taps afterward to even out the surface is the ideal combination.
What does butterflying a chicken breast mean?
Cutting horizontally into the thick side and stopping short of the far edge, so the breast opens like a book into one thin, even piece that stays attached at the hinge.
What is the difference between butterflying and making cutlets?
The hinge. A butterflied breast stays joined and opens flat, which you need for stuffing and rolling. Cutting all the way through gives you two separate cutlets.
Why do restaurant chicken breasts cook so evenly?
Because they are almost always butterflied or pounded to a uniform thickness first. Even thickness means the whole piece finishes at the same time.
How long does a butterflied chicken breast take to cook?
Far less than a whole one. In a hot pan it is typically three to four minutes per side, but cook to an internal temperature of 165°F rather than to the clock.
Cold breast, sharp knife, thick side first, flat palm on top. Cut slowly toward the far edge and stop half an inch short. If you go through, you have cutlets, and dinner is still fine.
