Goal / Why this exists

Transform flap meat (bavette) into tender, charred carne asada using a broiler instead of a grill. The loose grain of flap meat absorbs marinade beautifully, and high-heat broiling creates char without drying out the meat. Batch prep friendly — slice and portion for tacos, rice bowls, or salads all week.

Ingredients

Meat

  • 700-900g flap meat steak (bavette)
  • 8g kosher salt (Diamond Crystal)

Marinade

  • 60 mL soy sauce
  • 30 mL lime juice (1-2 limes)
  • 30 mL vegetable oil
  • 20g garlic (4-5 cloves), minced
  • 15 mL Worcestershire sauce
  • 10g cumin, ground
  • 5g black pepper
  • 5g smoked paprika
  • 5g dried oregano
  • 2-3 chipotles in adobo, minced (or 15 mL adobo sauce for less heat)

Optional Finish

  • Fresh cilantro, chopped
  • Extra lime wedges
  • Sliced radishes
  • Pickled jalapeños

Method

Prep & Marinade (15 min + resting)

  1. Trim flap meat if needed — remove any silver skin or excessive fat.
  2. Salt the meat on both sides. Let sit 10 min while making marinade.
  3. Make marinade: Whisk together soy sauce, lime juice, oil, garlic, Worcestershire, cumin, pepper, paprika, oregano, and chipotles in a bowl or large zip bag.
  4. Marinate meat: Add flap meat to marinade, turning to coat. Refrigerate minimum 30 min, up to 12 hours. Longer = more flavor penetration.
  5. Bring to room temp: Remove from fridge 20-30 min before cooking.

Broil (10-12 min)

  1. Position rack 4-6 inches from broiler element. Preheat broiler to high.
  2. Prep sheet pan: Line with foil for easy cleanup. Place a wire rack on top if you have one (better char, better drainage).
  3. Remove meat from marinade. Shake off excess — don’t wipe dry. Discard remaining marinade.
  4. Arrange on pan. If flap meat is very long, cut into 2-3 sections for even cooking.
  5. Broil 5-6 min on first side until charred and starting to caramelize.
  6. Flip carefully. Broil 4-5 min on second side.
  7. Check temp: Pull at 125-130°F for medium-rare, 135°F for medium. Meat will carry over 5°F while resting.

Rest & Slice (10 min)

  1. Rest on cutting board loosely tented with foil, 8-10 min. This is critical — don’t skip.
  2. Slice against the grain into thin strips (5mm). Flap meat has visible grain lines running lengthwise.
  3. Serve immediately or portion for meal prep.

Success Criteria

  • Charred exterior with visible caramelization spots
  • Pink interior (medium-rare to medium)
  • Tender slices that aren’t chewy — grain is cut crosswise
  • Smoky-savory flavor with cumin and chipotle coming through
  • Internal temp 130-140°F after resting

Variations

Korean-Style:

  • Replace marinade with: 60 mL soy sauce, 30 mL mirin, 20g gochujang, 15 mL sesame oil, 30g Asian pear (grated), garlic, ginger
  • Finish with sesame seeds and scallions

Citrus-Forward:

  • Add 30 mL orange juice to marinade
  • Use 2 limes instead of 1
  • Add 5g orange zest

Extra Spicy:

  • Double the chipotles
  • Add 5g cayenne to marinade
  • Serve with salsa macha or hot sauce

Storage & Reheat

Refrigerator: Sliced meat keeps 4-5 days in airtight container. Store any juices with the meat.

Reheating:

  • Best method: Quick sear in hot skillet, 1-2 min just to warm through. Don’t overcook.
  • Microwave: 1-2 min covered, but texture suffers slightly.

Freezer: Portion sliced meat into bags with juices. Freezes well 2-3 months. Thaw overnight in fridge.

Serving Ideas

  • Tacos: Corn tortillas, onion, cilantro, lime, salsa verde
  • Rice bowls: Over white rice with pickled veg, avocado, fried egg
  • Burrito bowls: Rice, black beans, corn, cheese, sour cream
  • Salads: Over romaine with cotija, pepitas, chipotle dressing
  • Quesadillas: With cheese and sautéed peppers

Notes

  • Flap meat is sometimes labeled “sirloin tip” or “bavette” — all the same cut.
  • The loose grain means it absorbs marinade faster than denser cuts.
  • Don’t marinate longer than 12 hours — acid will start to break down texture.
  • If you don’t have a broiler, use highest oven heat (500°F+) or a very hot cast iron.
