Sirloin Flap Steak

The Steak Lover's Hidden Gem: Irish Dexter Sirloin Flap Steak

Some of the most delicious steaks aren't the ones with the fanciest names.

Meet our Irish Dexter Sirloin Flap Steak, also known as bavette steak—a richly flavored, beautifully textured cut that's made for a sizzling grill, a hot cast-iron skillet, and a table full of hungry people.

Our Sirloin Flap Steak comes from our own heritage Irish Dexter cattle, raised on pasture at Fluffy Butt Farms and 100% grass-fed and grass-finished.

This cut has a distinctive, loose grain that absorbs marinades especially well. When cooked over high heat, rested, and sliced thinly against the grain, it delivers a delicious, satisfying steak experience.

If you love the bold flavor of skirt steak or flank steak, sirloin flap deserves a place on your grill.

Five Delicious Ways to Enjoy Sirloin Flap Steak

1. Grilled Garlic & Herb Bavette Steak

Marinate with olive oil, minced garlic, rosemary, thyme, and a splash of lemon juice. Grill over high heat, rest, and slice thinly against the grain. Serve with roasted potatoes and grilled asparagus.

2. Sizzling Steak Fajitas

Season with chili powder, cumin, garlic, lime juice, and a little oil. Grill or sear the steak, then slice into thin strips and serve with sautéed bell peppers, onions, warm tortillas, and fresh salsa.

3. Carne Asada Street Tacos

Marinate with lime juice, garlic, cilantro, and your favorite Mexican-inspired seasonings. Grill until beautifully browned, then chop or slice into bite-sized pieces. Serve in warm corn tortillas with diced onion, cilantro, and lime.

4. Cast-Iron Steak with Chimichurri

Season simply with salt and pepper and sear in a hot cast-iron skillet. Finish with a bright chimichurri sauce made from parsley, garlic, olive oil, vinegar, and red pepper flakes. Serve with crispy potatoes.

5. Steakhouse Sandwiches with Caramelized Onions

Cook the steak, rest, and slice very thinly against the grain. Layer onto toasted rolls with caramelized onions, provolone cheese, and a little horseradish cream for an unforgettable steak sandwich.

How to Cook Sirloin Flap Steak for the Best Results

1. Thaw completely. Thaw your steak in the refrigerator before cooking for more even results.

2. Season or marinate. Salt and pepper are delicious on their own, but this cut also responds beautifully to garlic, citrus, herbs, and savory marinades.

3. Get your grill or skillet hot. A hot cooking surface develops a flavorful browned exterior. Use a little cooking oil if needed.

4. Cook with attention. Sirloin flap can vary in thickness. Sear or grill, turning as needed, and use a meat thermometer rather than relying on a fixed cooking time.

5. Rest before slicing. Allow the steak to rest for approximately 5–10 minutes after cooking.

6. Slice against the grain. This is the secret to enjoying sirloin flap steak! Look for the direction of the muscle fibers and cut across them into thin slices to shorten the fibers and improve tenderness.

Food safety note: USDA recommends cooking whole beef steaks to a minimum internal temperature of 145°F followed by a 3-minute rest.

A Little Farm Kitchen Wisdom

Sirloin flap steak is not naturally as tender as a filet, and that's part of what makes it such a satisfying cut when prepared correctly.

Its real strengths are bold beef flavor, a marinade-friendly texture, and versatility. Give it a good sear, avoid unnecessary overcooking, and always slice thinly against the grain.

One more tip: If your steak is a long piece with grain direction that changes, cut it into smaller sections before slicing so you can cut each section correctly against the grain.
