Additional details
Bison sirloin steak is a great place to start if you're new to bison, and a reliable weeknight cut if you're not. Rich in flavor, naturally lean, and easier on the wallet than premium cuts, our grass-fed bison sirloin earns its place at the table on a Tuesday just as easily as a Saturday.
What Is Bison Sirloin Steak?
Cut from between the rib section and the rump, the bison sirloin (sometimes called buffalo sirloin steak or bison top sirloin steak) is lean but well-flavored, with a firm texture. It's one of our most versatile grass-fed bison steaks, falling between the more delicate filet and the richness of ribeye.
What Does Bison Sirloin Taste Like?
Bison sirloin has a clean, slightly sweeter flavor than most people expect, with rich, deep beefiness that holds up beautifully on its own. We love it simply seasoned with salt, pepper, and garlic, though it takes well to bold marinades too. If you're curious how bison steak compares to beef, bison tends to be leaner with a cleaner finish. Most people are pleasantly surprised.
Raised on Regenerative Pastures
Our bison graze on native grasses across open regenerative pastures for their entire lives. We've seen firsthand how rotational grazing builds healthier soil and produces clean, quality meat. Browse our full grass-fed bison collection to explore everything we raise.
Free From Hormones, Antibiotics, and GMOs
No shortcuts, no confusing label tricks. Our bison are raised without GMOs, antibiotics, hormones, or grain, and we're happy to talk about it any time you visit the farm. Our Beef Favorites Box is a great way to explore beyond bison.
Bison Sirloin vs. Bison Ribeye
The sirloin is leaner with a clean, straightforward beefy flavor that fits well into any weeknight. Bison ribeye is richer and more marbled, best saved for when you want to slow down and savor it. Still exploring? Our bison NY strip steak is worth a look too.
Bison Sirloin vs. Bison Filet Mignon
Both are excellent cuts with different strengths. Our bison filet mignon is the most tender cut we offer and worth every penny for a special occasion. Bison sirloin is firmer with a beefier character and the kind of everyday versatility that earns a permanent spot in your freezer.
How to Cook Bison Sirloin Steak
Bison sirloin cooks faster than you might expect, so pay close attention to avoid overcooking. For the grill, cook over high heat for a few minutes per side, then let it rest before slicing. For the stovetop, we love it pan-seared in a cast-iron skillet with a little butter. However you cook it, a meat thermometer takes the guesswork out and helps you hit your preferred doneness every time.
Bison Sirloin Recipe Ideas
Grill it with herb butter for a quick weeknight dinner or slice it thin for steak salads and fajitas. A salt, pepper, and garlic rub is all it needs most nights. For something with a little more depth, a simple olive oil and herb marinade works beautifully before it hits the heat.
