Raw Sirloin Flap Meat

What is sirloin flap steak?

Sirloin flap meat comes from the bottom sirloin and is considered a low-priced beef steak. In New England, this cut is known as sirloin tips; other names include faux hanger, sirloin bavette, or sirloin flap meat. Because it is cut thin, this steak is often confused with other flat steaks like skirt or hanger steaks. Typically sirloin flap steaks are ground up and used for beef sausages and hamburger patties. It is also a popular choice for making carne asada to use in tacos, fajitas, etc.

How do you prepare sirloin flap steak?

We recommend marinating this cut of beef. Like most flat steaks, flap meat is tough and coarse in texture, so it holds onto the acids and flavors quite well. However, you can season it with a simple salt and pepper rub, grill it hot and fast, and it will be delicious. Our recipe includes a rich, savory marinade that compliments the steak’s natural beefy flavor.

  • Sirloin flap steak, 2 pounds

  • white sugar (sub with brown sugar for a more caramel/molasses flavor)

marinating meat

Marinating Sirloin Flap Steak:

Place the flap steaks in a resealable plastic bag. Whisk the marinade ingredients in a bowl, and pour the mixture over the steaks. Seal the bag, work the marinade around, and place it into your refrigerator for 6-12 hours.

Note: Always have a instant read thermometer nearby!


  • Preheat your grill to 400 degrees F. These steaks cook over direct heat. If you’d like, add a moderate wood (pecan, cherry, or maple.) a few minutes before grilling.
  • Remove steaks from the marinade and place them onto the grill. Carefully pour any leftover marinade over the top of the steaks. If you find this task too messy, spoon or brush on the marinade instead. 
  • Grill steaks for roughly 12-15 minutes, turning 2-3 times during cooking. We recommend cooking sirloin flap steak to medium-rare or medium doneness. It’s naturally chewy, so rare will not produce the best results. Read our Steak Temperature Guide to help you determine when to pull your steak.

Slicing and serving:

Rest the grilled sirloin flap steak on a clean cutting board for 10 minutes and then slice with the grain rather than against it. The grain is situated differently on flap steaks, and the meat texture is coarse. So, slicing with the grain will yield tender, juicy pieces. Carve into thin slices rather than large chunks or strips. Serve with your favorite sides like corn and potato salad, or make a delicious steak salad or sandwiches. Chop it up, add breakfast potatoes, and make yourself a nice breakfast hash.
