What is Beef Flap Steak?

Understanding This Versatile Cut

Tucked away in the bottom sirloin section of the steer, beef flap steak (sometimes labeled bavette or sirloin flap) delivers extraordinary flavor without the premium price tag. This rectangular cut features stunning intramuscular marbling throughout, creating natural flavor pockets that yield incredible juiciness when prepared properly.

Think of it as the perfect middle ground between flank and skirt steak – offering the tenderness of the former with the robust beefy punch of the latter. The distinctive grain structure allows marinades to penetrate deeply, while its relatively thin profile means lightning-fast cooking times.

Why Choose Beef Flap Steak for Grilling?

When planning your next cookout, consider these compelling reasons to reach for beef flap steak:

  • Remarkable flavor concentration – The generous marbling means exceptional taste without requiring premium prices
  • Marinade-friendly structure – The loose grain pattern absorbs seasonings magnificently
  • Budget-conscious indulgence – Experience premium taste while spending significantly less than you would on ribeye or strip steak
  • Weeknight wonder – Quick-cooking nature makes it perfect when time pressures loom
  • Visual drama – The striking grain patterns create impressive serving presentations

Local butchers often set aside their personal stashes of this underappreciated cut, so developing a friendly relationship with your meat purveyor might grant special access to this hidden treasure.

How to Cook Beef Flap Steak on the Grill: 5 Easy Steps

Step 1: Prepare Your Beef Flap Steak

Proper preparation establishes the foundation for exceptional results. Follow these crucial pre-grilling steps:

  1. Remove your steak from refrigeration 30-45 minutes beforehand, allowing it to approach room temperature
  2. Thoroughly pat surfaces dry using paper towels (moisture prevents proper searing)
  3. Evaluate fat distribution, trimming excessive portions while maintaining flavor-enhancing sections
  4. Brush all surfaces lightly with olive oil
  5. Season generously with kosher salt and freshly cracked pepper on both sides
  6. Consider additional flavoring elements like crushed garlic or fresh herbs

Flavor Booster: Create a simple yet effective marinade by whisking together 3 tablespoons olive oil, 2 tablespoons soy sauce, 1 tablespoon Worcestershire sauce, 3 minced garlic cloves, and 1 teaspoon honey. Pour over steak in a sealed container or zip-top bag, refrigerate for 2-4 hours, then bring to room temperature before grilling.

Step 2: Preheat and Prepare Your Grill

Creating the ideal cooking environment ensures consistent results every time:

  1. For gas grills: Preheat to high (450-500°F) for 10-15 minutes with lid closed
  2. For charcoal enthusiasts: Create a two-zone fire configuration by banking most coals to one side
  3. Scrape grates thoroughly with a quality grill brush
  4. Oil grates by dipping folded paper towel in vegetable oil and rubbing across surfaces using tongs
  5. Verify temperature has reached target range before introducing steak

Safety First: Always maintain proper ventilation when grilling, and keep a spray bottle filled with water nearby to manage unexpected flare-ups without compromising your perfect cook.

Step 3: Grill Your Beef Flap Steak to Perfection

Now comes the exciting part – transforming raw potential into culinary achievement:

  1. Place your flap steak directly over the hottest grill section
  2. Resist the temptation to move or peek for 3-4 minutes while developing gorgeous grill marks
  3. Flip once using tongs (never pierce with a fork) and cook second side for 2-3 minutes
  4. For doneness beyond medium-rare, relocate to indirect heat zone (or reduce burner temperature)
  5. Monitor internal temperature frequently using your meat thermometer
DonenessInternal TemperatureTotal Cooking Time
Rare125°F5-6 minutes
Medium-Rare135°F7-8 minutes
Medium145°F9-10 minutes
Medium-Well150°F11-12 minutes
Well-Done160°F13-14 minutes

Chef’s Insight: The sweet spot for beef flap steak typically falls between medium-rare and medium. This range maximizes tenderness while allowing the intramuscular fat to render properly, creating that melt-in-your-mouth sensation that distinguishes truly excellent grilled steak.

Step 4: Rest Your Grilled Beef Flap Steak

Patience during this critical phase separates amateur efforts from restaurant-quality results:

  1. Remove steak when thermometer registers approximately 5°F below your target temperature
  2. Transfer to a clean cutting board or platter
  3. Tent loosely with aluminum foil, creating an environment that retains heat without steaming
  4. Allow a full 5-10 minute rest period during which carryover cooking completes the process
  5. Resist all urges to cut into the meat prematurely (however tempting)

Science Explained: During cooking, intense heat drives juices toward the center of the meat. Resting allows these flavorful liquids to redistribute throughout the muscle fibers rather than escaping onto your plate. This simple patience test results in significantly juicier, more flavorful bites.

Step 5: Slice and Serve Your Beef Flap Steak

The final presentation showcases your grilling mastery:

  1. Identify the direction of muscle grain (visible as parallel lines)
  2. Position your knife perpendicular to these lines, creating thin slices across the grain
  3. Maintain a consistent thickness of approximately ¼-inch for ideal texture
  4. Arrange attractively on a warmed platter
  5. Consider finishing with a light sprinkle of flaky sea salt or a dollop of compound butter

Perfect Pairings: Complement your masterfully grilled flap steak with simple sides that balance the rich flavors:

  • Bright chimichurri sauce
  • Grilled asparagus spears
  • Garlicky roasted potatoes
  • Peppery arugula salad with lemon vinaigrette
  • Full-bodied red wine like Malbec or Syrah

Persistent Flare-Ups

  • Solution: Trim more aggressively before cooking and manage hot spots by moving steak strategically

Inconsistent Doneness

Frequently Asked Questions About Beef Flap Steak

What is another name for beef flap steak?

You might spot beef flap steak under various aliases including bavette, sirloin flap, bottom sirloin butt flap, or simply flap meat. Regional butchery traditions influence these naming variations, but rest assured they reference the same delectable cut.

How long should I marinate beef flap steak before grilling?

The ideal marinating window falls between 2-4 hours for beef flap steak. Unlike denser cuts requiring overnight treatment, flap steak’s naturally loose grain structure allows flavors to penetrate relatively quickly. Extending beyond 12 hours risks compromising texture, particularly with acidic marinades.

Can beef flap steak be cooked to well-done?

While you certainly can cook beef flap steak to well-done temperatures, you’ll achieve noticeably superior results in the medium-rare to medium range (135-145°F). The relatively lean composition means extended cooking can diminish tenderness. If well-done preparation remains your preference, consider tenderizing marinades and particularly thin slicing against the grain.

How do I know which direction is “against the grain” when slicing beef flap steak?

Identifying grain direction becomes straightforward once you know what to seek. Examine your cooked flap steak for visible parallel lines running through the meat—these represent muscle fiber bundles. Slicing perpendicular (not parallel) to these lines cuts across fiber structures rather than along them, significantly enhancing tenderness by shortening tough fibers into bite-sized segments.

How much beef flap steak should I plan per person?

For hearty main-course portions, calculate 6-8 ounces of raw beef flap steak per adult diner. When building diverse menus featuring multiple proteins or substantial sides, adjust downward to 4-6 ounces per person. Factor in approximately 15-20% cooking shrinkage when purchasing.

Can I cook beef flap steak from frozen?

While technically possible, defrosting completely before grilling delivers dramatically superior results. Cooking directly from frozen typically creates a problematic temperature gradient—overdone exterior surrounding an undercooked center. When time constraints exist, employ the cold-water thawing method by sealing in waterproof packaging and submerging in cold water (changing every 30 minutes) rather than attempting frozen grilling.
