Set a bavette and a flank steak side by side on a cutting board and they'll look nearly identical, long, flat, and thin. Cook them the same way, though, and you'll notice the difference fast. These two cuts share a general neighborhood on the cow but come from different muscles entirely, and that distinction shapes everything from texture to how you should season them.

Where Each Cut Comes From

  • Flank steak comes from the rectus abdominis, a muscle in the lower belly that works hard helping the animal move. That constant use makes the meat lean and firm, with a clear, tight grain running in one direction. Most flank steaks run a half inch to an inch thick.
  • Bavette, sometimes called flap steak, comes from the bottom sirloin instead. This muscle does far less work than the flank, which gives it a looser grain and noticeably more marbling. It also tends to run a bit thicker than flank, and that extra fat makes for a juicier bite.

Grain, Marbling, and Flavor

Flank's tight, parallel grain carries a clean, deep beef flavor, but it needs careful slicing to avoid toughness. Bavette's open, coarse grain does the opposite: it holds onto a dry rub or marinade beautifully, and the extra marbling keeps the meat moist through a hot sear. Neither cut wants to go past medium-rare; the long fibers in both tighten up and lose their juice if pushed further.

Feature Bavette Flank
Primal Bottom sirloin Flank
Grain Loose, coarse Tight, parallel
Marbling Moderate to high Low, lean
Thickness 1-1.5 inches 0.5-1 inch
Best Use High-heat sear Fast grill or sear

How to Cook Both

  • Bring the steak to room temperature, about 30 minutes out of the fridge.
  • Get your pan or grill aggressively hot before the meat goes on.
  • In the final minute, add a pat of butter and baste for extra richness.
  • Pull at 120°F for rare or 125°F for medium-rare, using a thermometer rather than guessing.
  • Rest 5-7 minutes on a board.
  • Slice thin, across the grain.

Both cuts cook fast, 3-5 minutes per side over high heat, so stay close and don't wander off.

Slicing Against the Grain

This is the step that determines whether either steak feels tender or tough. Find the direction the muscle fibers run, then cut across that line rather than with it. Shortening those fibers is what makes the difference between a chewy bite and an easy one; studies on meat texture have found that cutting against the grain can cut the effort needed to chew a piece of beef by half. A slight angled cut, rather than straight down, makes each slice look larger and stay just as tender.

When to Reach for Each

Flank works well in dishes where the beef shares the plate, tacos, stir-fry, anything where its clean, lean flavor plays a supporting role. It's also the better choice if you're making jerky, since its leanness helps it dry well and keep. Bavette shines as the main event on its own plate, standing in for a strip steak or sirloin with a richer, more forgiving bite.
