What is flap steak?

Flap steak comes from the sirloin primal, is packed full of flavor, and perfect for that delicious fajita dish or marinating. But, with about a dozen interchangeable titles, flap steak’s notoriety may be overshadowed by sheer naming overload. It can be hard to remember what it all means when you’re shopping for beef, so we’ve assembled a list of other common names for flap steak.

Flap steak is also known as:

  • Bavette
  • Flap meat
  • Bottom sirloin bavette
  • Bottom sirloin butt
  • Bottom sirloin flap
  • Sirloin flap
  • Sirloin Bavette

Now, once you fall in love with the flap steak, you’ll already be a naming expert and know how to find it at your favorite retailer.

Is flap steak the same as skirt steak?

Great question. Though the skirt and flap do share some characteristics, it’s important to note that they come from different parts of the animal. The skirt steak (both the inside skirt and outside skirt) come from the plate, or the underside of the animal’s chest. The flap steak hails from the sirloin, or the mid-back of the animal. Another difference: flap is more tender than the skirt steak, while the skirt steak offers a slightly more robust, beefier flavor.

What is flap steak good for?

Like other hearty cuts including the flank and skirt steaks, flap steak is ideal for fajitas, sandwiches, and alongside equally flavorful side dishes like garlic mashed potatoes or tahini and lime-dressed veggies.

Here’s a secret: flap meat historically was a cut that butchers kept out of the meat case because they were saving it for themselves. Fortunately, the secret is slowly getting out, so it’s becoming easier to find this cut in stores. Ask your butcher for an Aspen Ridge Natural Angus Beef bavette the next time you’re shopping.

How do I cook flap steak?

As we mentioned above, flap steak really shines when it’s marinated. The marinade’s ingredients will tenderize and add flavor to the meat. Once it’s flavored up, flap steak often ends up on the grill, where the high heat adds a pleasant, smoky char while keeping the meat moist.

Flap steak also works well when broiled or as part of a beef stir-fry.

How to Grill Flap Steak

  1. Preheat the grill to high.
  2. Take steak out of marinade or packaging and pat dry with a paper towel.
  3. Sprinkle with salt.
  4. Grill 2-3 minutes per side for medium-rare. Use a meat thermometer to ensure your steak is at the temperature you desire.
  5. Let stand for 5 minutes before thinly slicing against the grain.
