Two-Zone Bison Burgers with Ancho Rub and Garlic-Chive Sauce
Bison is lean and dries out fast, so these patties get a little cold butter, a hard sear, and a finish on the cool side of the grill. The ancho-cumin rub and cool chive sauce do the rest.

Steps
- Make the sauceStir the sour cream, mayonnaise, chives, garlic, lime juice, and salt together in a small bowl. Cover and refrigerate while you cook.
- Shape the pattiesGrate the frozen butter into the bison. Fold it in gently with your hands, just until combined. Divide the meat into 6 equal portions of about 5 1/3 ounces each. Shape each into a patty about 4 inches wide and 3/4 inch thick, and press a shallow dimple in the center with your thumb. Place on a tray and chill at least 15 minutes.
- Heat a two-zone grillLight half the burners on high and leave the others off. Close the lid and preheat 10 minutes until the hot side reads 450°F to 500°F. Clean the grates, then wipe them with oil.
- Grill the onionBrush the onion rounds with olive oil and grill them over direct heat for 4 to 5 minutes per side, until tender with grill marks. Move them to a plate.
- Season and searMix the ancho, paprika, cumin, garlic powder, pepper, and salt. Sprinkle the rub evenly over both sides of the patties, about 1 1/2 teaspoons each. Place them over the hot zone and sear for 3 minutes with the lid open. Flip once and sear 3 minutes more.
- Finish on the cool sideMove the patties to the cool zone and close the lid. Cook 3 to 5 minutes, until an instant-read thermometer in the center reads 160°F. Lay a slice of cheddar on each patty in the last minute and close the lid to melt it.
- Toast the buns and restSet the buns cut side down on the cool zone for 1 to 2 minutes, until lightly toasted. Move the patties to a plate and rest for 3 minutes.
- Build and serveSpread the chive sauce on both halves of each bun. Stack the lettuce, tomato, patty, and grilled onion on the bottom bun, add the top bun, and serve right away.
Bison makes a great burger, but it has far less fat than beef. Cook it like a chuck patty and you end up with a dry puck. These patties get a small amount of cold butter, a quick sear over high heat, and a finish on the cool side of the grill. They come out browned outside and juicy inside.
Set up the grill for two zones
On a gas grill, light half the burners on high and leave the other half off. Close the lid and let it heat for 10 minutes. The hot side should read around 450°F to 500°F. Scrape the grates with a brush, then wipe them with an oiled paper towel held in tongs.
If the grates are caked with old grease, that grease will flare up under lean meat and char the outside before the middle is ready. A clean grill and clean burner tubes make this recipe much easier. If a burner is burning uneven or a flame tamer is rusted through, check the parts diagrams for your brand and order replacements from the Pro Grill parts store.
Keep the meat cold and the mixing light
Freeze the butter for 15 minutes, then grate it on a box grater straight into the bison. Fold it in with your hands just until it is spread through the meat. Overmixing makes dense, rubbery burgers. Shape the patties, press a shallow dimple in each center with your thumb, and put them back in the fridge until the grill is ready.
Salt goes on the outside of the patty with the rub, right before it hits the grates. Salt worked into ground meat early gives it a springy, sausage-like bite.
How to tell they are done
Ground bison needs to reach 160°F in the center, the same as ground beef. Do not pull it at 120°F or 130°F the way you might a steak. Slide an instant-read thermometer in through the side of the patty so the tip sits in the middle.
Color is not a reliable guide. Bison looks darker and browner than beef at every stage. Go by the thermometer and let the patties rest 3 minutes. The temperature will climb a few degrees as they sit.
What goes wrong
- Dry, gray patties: they stayed too long on the hot side. Move them to the cool side as soon as both faces are seared.
- Patties that fall apart: the meat got warm or was overworked. Chill them for at least 15 minutes before grilling and flip only once.
- Flare-ups: there is very little fat here, so flare-ups usually come from grease already in the firebox. Clean out the drip tray before you cook.
- Bitter crust: ancho and paprika scorch if the grates are much hotter than 500°F. Turn the burners down a notch if the rub starts to blacken.
If you ever smell gas while lighting the grill, shut off the valve at the tank, step away, and call a pro. You can find an insured grill pro near you.
Serving
Toast the buns on the cool side while the patties finish. Stack them with the cheddar, grilled red onion, tomato, and butter lettuce, then add a big spoonful of the chive sauce. A cold lager or a crisp slaw goes well on the side.
FAQ
What internal temperature should bison burgers reach?
Cook ground bison to 160°F in the center, measured with an instant-read thermometer. Ground meat can carry bacteria all the way through, so it needs a higher temperature than a whole steak.
Why add butter to bison burgers?
Bison is very lean, and a little fat keeps the patty juicy. Grated cold butter spreads through the meat without melting while you shape the patties. You can use the same amount of grated cold beef suet or a splash of olive oil in a pinch.
Can I make these on a charcoal grill?
Yes. Bank the hot coals on one side and leave the other side empty. Sear over the coals, then move the patties to the empty side with the lid on, and cook to 160°F.
Can I shape the patties ahead of time?
You can shape them up to 8 hours ahead and keep them covered in the fridge on a parchment-lined tray. Wait to apply the rub until just before cooking.
