This grilled sirloin flap steak is a must-try recipe!

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.
How do you prepare sirloin flap steak?
We recommend marinating this cut of beef. Like other flat steaks, sirloin 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 marinade that adds a delicious savory flavor you want with beef.

What you’ll need:
- Sirloin flap steak, 2 pounds
- red wine vinegar
- olive oil
- Worcestershire sauce
- oregano
- celery salt
- white sugar (optional)
- coarse salt (kosher)
- black pepper
- onion powder
- fresh garlic
- herbs found in your spice rack
- red pepper flakes (optional)
Marinating Sirloin Flap Steak:
Place your steaks in a resealable plastic bag. Whisk all of your marinade ingredients in a bowl, and submerge your sirloin flap steaks in the mixture. Seal the bag and place it into your refrigerator for 6-12 hours.
Grilling:
- Preheat your grill to 400 degrees F. These steaks cook over direct heat. If you’d like a bit of smokiness, add a moderate wood (pecan, cherry, etc.) 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, you can spoon or brush on the marinade instead.ย
- Grill steaks for roughly 12-15 minutes, turning two or three times during the cooking process. 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 ourย Steak Temperature Guide to help you determine when to pull your steak.

Slicing and serving:
Let the meat rest for 10 minutes. The best method for slicing your grilled sirloin flap steak is to cut with the grain rather than against it. This is because of its coarse texture and the direction the grain is situated on the steak.
Aim for thinner slices rather than large chunks or strips. Serve with your favorite sides, chop up the leftovers, add breakfast potatoes and make yourself one heck of a delicious breakfast hash.
