Bison Ribeye
The rib eye roll — longissimus dorsi with the spinalis cap wrapped around one edge. On beef that cap is the fattiest, most prized part of the steak. On bison it is simply the tastiest part, because bison deposit fat around muscles rather than through them.

The steak whose whole reputation is marbling, from the animal that doesn't marble.
Buy it if
You want a ribeye's beefy flavor without a beef ribeye's fat, and you own a thermometer.
The fat is in a different place, not just in a smaller amount. Cattle bred for grain finishing lay fat down inside the muscle, in flecks between bundles of fiber. Bison put theirs as a cap on the outside and in the seams between muscles. That distinction matters more than the total: seam fat can be trimmed off and cooked around, while intramuscular fat cannot be removed and melts into the meat from the inside as it heats.
Which is why this is the cut that changes most. A beef ribeye is the marbling cut — marbling is most of what the grading system measures, and it is the reason ribeye costs what it costs. Take it away and you have not made a slightly worse ribeye; you have made a different steak. Darker, firmer, cleaner-tasting, closer in character to a strip loin than to the beef ribeye it is cut from.
Cook the seams, not just the middle. The cap and the seam fat will render if you give them direct heat and a little longer than the eye needs. Stand the steak on its fat edge in the pan for a minute before you lay it flat — that is the fat you paid for, and it is the only fat this steak has.
The eye itself holds no reserve, so it wants heat that arrives fast and then stops. Thick steaks reward a reverse sear; thin ones want a very hot pan and no patience at all.

| Cook to | Medium-rare, 130–135°F, and no further. Pull at 130°F and let carryover finish it — there's no intramuscular fat to cover an overshoot, so 140°F is dry. Rest 5 minutes. |
Stand it on the fat edge first and render the cap, then lay it flat. That gives you the only fat on the steak, and something to baste with.
Go in cold from the fridge — a cold centre lags while the surface browns, which is free margin on a steak that has none. Oil the steak, not the pan. Rest it 5 minutes on a warm plate rather than under foil, which steams off the crust you just built.

Common questions
Is the fat cap worth eating, or should I trim it?
It is the best part, and it is the only significant fat on the steak, so leave it on through cooking. Render it deliberately by standing the steak on that edge for a minute in a hot pan. Cut away raw, you have removed the one thing keeping this from eating like a lean roast.
Why is bison meat so much darker than beef?
More myoglobin, the oxygen-storing protein in muscle. Bison stay physically active and were never bred for rapid confined finishing, and hard-working muscle carries more of it. It is the same reason duck breast is dark and chicken breast is not — colour tracks how much a muscle actually gets used.
Does dry-aging do anything for a steak this lean?
Less than it does for beef. Dry-aging works partly through enzymes tenderising the muscle and partly by drying and concentrating fat, and the second half barely applies here. It also costs yield you are paying for. Fresh or wet-aged bison is not the compromise it would be on a well-marbled beef steak.
Should I buy it bone-in?
Only for the presentation. The bone adds no flavour — it insulates the meat against it, so that side cooks slower, which is an argument for buying the steak thick rather than for buying the bone. Either way you are paying steak prices for bone weight.
