Additional details
If fajitas, carne asada, or a fast weeknight steak dinner is your kind of meal, our grass-fed flank steak belongs in your freezer. It's a lean, flavorful cut built for bold marinades and high-heat cooking with deep, satisfying flavor.
What Is a Flank Steak?
Flank steak comes from the abdominal muscles below the loin. It's a long, flat, boneless cut with a pronounced grain and bold, beefy flavor. It's leaner than rib or loin cuts, so always slice against the grain after cooking. That simple step shortens the muscle fibers, making every bite tender.
Bold Flavor, Fast Cooking
Flank steak is a weeknight workhorse. It cooks in minutes over high heat, and its beefy flavor holds its own against bold seasonings. Whether you're feeding a crowd on taco night or pulling together a quick steak dinner, this is the cut that delivers.
Flank Steak vs. Skirt Steak
Both are lean, flat cuts popular for grilling, but they're not identical. Flank is wider, thicker, and slightly leaner, with a cleaner slice that works well for plated dishes. Skirt steak is thinner and carries a more intense beefy flavor, making it the more traditional choice for Tex-Mex fajitas. Flank is the better pick when presentation matters, while skirt delivers flavor intensity.
From Regenerative Pastures
Our 100% grass-fed, grass-finished cattle graze on diverse grasses and forage their entire lives, rotating to fresh pasture to keep the land healthy. On our farm and across our partner farms, we've seen how this diet produces grass-fed beef with a cleaner, more mineral-rich flavor that pairs with bold seasonings and marinades. No grain finishing. No shortcuts.
Free From Hormones, Antibiotics, & GMOs
Every cut comes from cattle raised without hormones, steroids, antibiotics, or GMO feed. We hold our partner farms to the same high standards as our own, no exceptions. Explore our full lineup of grass-fed steaks to find your next favorite cut.
Versatile Across Cuisines
The lean muscle and visible grain of flank steak absorb flavors deeply. Bold marinades, citrus, garlic, chimichurri, soy, or chili-based blends all pair beautifully with flank beef. We love it for steak fajitas, Korean bulgogi, grilled steak salads, carne asada tacos, beef stir-fry with vegetables, and London broil with roasted vegetables. Pair it with our grass-fed ground beef for a complete taco night spread.
How to Cook Grass-Fed Flank Steak
Grill or sear over high heat for the best results, 4 to 5 minutes per side on a hot grill or in a cast-iron skillet. You can also broil for 4 to 5 minutes per side. Target medium-rare to medium (130–145°F) for optimal tenderness and juiciness. Because this is 100% grass-fed beef, it may cook faster than conventionally raised beef, so keep a close eye on it. Let the steak rest 5 to 10 minutes before slicing thin against the grain.
Storage & Preparation
With home delivery, your grass-fed flank steak ships frozen and vacuum-sealed. We guarantee it in your freezer for up to one year. To thaw, place it in the refrigerator overnight. For a head start on flavor, add your marinade to the bag while it thaws. Once thawed, cook within three days. Leftover slices keep well in the fridge and work beautifully in sandwiches, grain bowls, or salads.

Bruce's Take on Beef Flank Steak
"Flank steak is a lean, flavorful cut that’s best when marinated and cooked quickly over high heat. It’s a great value steak with a satisfying bite, perfect for slicing thinly against the grain. While it benefits from proper preparation, it’s easy to grill or pan-sear for a bold and beefy meal." - Bruce (the 6th son)

Common Questions About our Beef Flank Steak

Flank steak is a lean, flat cut taken from the belly of the cow. It’s known for its beefy flavor and visible grain.
-
Grill or sear over high heat and target medium-rare to medium (130–145°F) for the best results. Because it comes from 100% grass-fed cattle, this cut may cook faster than conventionally raised beef, so watch it closely. Let it rest for 5 to 10 minutes after cooking, then slice thin against the grain.
-
Both are lean cuts built for high heat and bold flavors. Flank steak is wider and slightly leaner, while skirt steak is thinner with a more intense flavor.
-
A marinade is a great choice for flank steak. The lean muscle and visible grain absorb flavors deeply, so bold marinades like citrus, garlic, soy, and chimichurri all work beautifully. Thirty minutes to two hours is ideal, long enough to build flavor without breaking down the texture.
