SUMMARIZE & SAVE THIS CONTENT ON

I'm an endurance athlete, so high-protein dinners that actually taste good are non-negotiable in my kitchen, and bison has quietly become one of my favorite ways to hit that. It's leaner than beef but never bland, and after training I want something this satisfying without a pile of dishes.

These started as a riff on my Greek feta turkey burgers, which are one of the most popular burger recipes on my site. I brought the same feta, oregano, and grated-onion approach to bison, tested it through more than a few dry batches, and landed on the version that stays juicy every time.

I love serving them topped with my healthy low-fat tzatziki or paired with sides like my Mediterranean dense bean salad and air fryer sweet potato wedges. That combo is my go-to summer plate, and it's the meal I come back to most when I want something healthy that still feels like a treat.

Why You'll Love This Recipe

Genuinely juicy, not dry. Grated onion melts into the lean meat, and an egg + yolk holds it together. These are the two fixes I landed on after a few too-dry early batches.
An upgrade on the usual beef burger. Bison is leaner and a little richer, so it feels like something special without any extra work.
That Greek twist. Feta and oregano give every bite a salty, herby pop, and you can go fully Mediterranean with chopped spinach or keep it simple.
One bowl, about 20 minutes. No fancy equipment and easy enough for any night of the week.
Cooks however you like. Grill, skillet, or air fryer all work.
30g of protein per patty. Why these stay in my regular rotation.

Ingredients You'll Need

Labeled bison burger ingredients: ground bison, eggs, feta, spinach, Dijon mustard, and seasonings.

Ground bison. Leaner and a little richer than beef. Look for 90/10 if you can find it, so the patties hold together without drying out.
Grated yellow onion. The secret to juicy bison. Grating it (rather than dicing) lets the onion melt into the meat as it cooks, adding moisture that lean bison doesn't have on its own. It's the same trick I use in my juicy grilled turkey burgers.
Egg. You need 1 egg + 1 yolk. It binds everything so the patties stay tender and hold their shape instead of crumbling, which lean meat tends to do.
Dijon mustard. A little tang and depth in the mix; you won't taste it as mustard.
Feta cheese. The Greek twist. Crumbled in for salty, briny pockets throughout the patty.
Dried oregano, garlic powder, and paprika. The Mediterranean backbone, warm and savory.
Salt and black pepper. Essential for seasoning. Feta cheese is salty, so I actually like to only add a little salt to these burgers.
Baby spinach (optional). Finely chopped and folded in for extra greens and a fuller Mediterranean flavor.
Toppings. Toasted buns, butter lettuce, tomato, red onion, ketchup, or mustard, however you like to build it.

Ingredient Substitutions & Variations

Ground bison: Ground turkey, chicken, or lean beef all work if bison is hard to find. Go by doneness rather than time, since each cooks a little differently.
Feta: Crumbled goat cheese or blue cheese keeps the briny, tangy note. For something milder, mozzarella or provolone melts in nicely.
Egg: Out of eggs? A tablespoon of mayo or a splash of olive oil holds the patties together and keeps them moist.
Make it dairy-free: Leave out the feta. The grated onion and egg still keep the patties juicy, so you don't lose the texture.
Bunless and low-carb: Skip the bun and serve over a Greek salad (similar to my Greek chicken meatballs) or in a lettuce wrap, which is how I eat them on meal-prep days.
Make it Spicy: A pinch of red pepper flakes or a little harissa adds a kick to the Greek flavors.

How to Make Juicy Bison Burgers (Step-by-Step)

Ground bison in a white bowl with eggs, Dijon mustard, feta, chopped spinach, and seasonings before mixing.

Step 1: Combine the ingredients. Add the ground bison, Dijon, grated onion, egg, oregano, garlic powder, paprika, salt, pepper, and feta to a large bowl. Add the chopped spinach now, too, if using.

Step 2: Mix gently. Use your hands to mix just until everything comes together. Stop there, overworking the meat is what makes lean bison dense and tough.

Step 3: Shape the patties. Divide the mixture into 4 equal portions and shape into patties about ½-inch thick. Press a shallow thumb dimple into the center of each, so they cook flat rather than puff up.

Step 4: Cook over medium-high. Heat a lightly greased grill, grill pan, or skillet over medium to medium-high. Cook the patties about 4 to 5 minutes per side.

Step 5: Check temp, rest, and serve. Pull the burgers at 140 to 145°F for medium, let them rest a few minutes so the juices settle, then build them on toasted buns with your favorite toppings.

Tips for Juicy Bison Burgers

Don't overcook them. This is the one that matters most. Bison is much leaner than beef, so it goes from juicy to dry fast. Pull the burgers at 140 to 145°F for medium and let the temperature carry up as they rest.
Use a thermometer, not the clock. Grills and skillets all run differently, so an instant-read thermometer is the difference between perfect and dry. It's the single best upgrade for cooking lean meat.
Add the grated onion. Grated (not diced) onion melts into the meat as it cooks and is the main reason these stay moist. It's the same trick I use in my grilled turkey burgers.
Mix gently and don't overwork it. Overmixing makes the patties dense and tough. Combine everything just until it comes together, then stop.
Make a thumb dimple in each patty. A small indent in the center keeps the burgers from puffing into a dome, so they cook flat and even.
Let them rest before serving. A few minutes off the heat lets the juices redistribute instead of running out the moment you bite in.

What Temperature to Cook Bison Burgers

Cook bison burgers to 140 to 145°F for medium, the sweet spot where they stay juicy. Bison is lean, so a few degrees past that dries them out; pull them early and let them rest. For food safety, the USDA recommends cooking ground meat to 160°F.

Medium-rare: 130 to 135°F, very pink and juicy
Medium: 140 to 145°F, slightly pink, and the best balance for bison
Medium-well: 150 to 155°F, just a hint of pink
Well-done: 160°F and up, cooked through but easy to overdry

What to Serve with Bison Burgers

These are the sides I make on repeat with these burgers. Each one comes together fast and plays well with the Greek flavors:

Healthy Greek pasta salad - the natural match here, same feta-and-oregano flavor family, and it holds up for days in the fridge.
Crispy oven-roasted potatoes - golden and crisp, the closest thing to fries without the fryer. My most-requested cookout side.
Mediterranean dense bean salad - high-protein and packed with veggies, filling enough to round out the plate.
Summer avocado corn salad - sweet corn, creamy avocado, and lemon, a backyard-cookout side that balances the rich burger.
Watermelon basil salad - my favorite summer pairing; the juicy watermelon cuts through the savory bison.

How to Store and Reheat

Store leftovers in an airtight container in the fridge for up to 4 days.
Reheat gently to keep them juicy: in a skillet over medium-low heat for 2 to 3 minutes per side, in the microwave in 30-second bursts, or in a 350°F oven for about 10 minutes.
Freeze cooked patties for up to 3 months. Cool completely, then wrap individually and store in a freezer-safe bag with parchment between each one.
Freeze raw patties on a parchment-lined sheet pan until solid, then transfer to a freezer bag. Cook from frozen or thaw overnight in the fridge first.
Thaw overnight in the fridge before reheating for the most even results.

Bison Burgers FAQs

Does ground bison taste like beef?

Close, but better, in my opinion. Bison tastes like beef with a slightly richer, naturally sweeter flavor, and it isn't gamey at all. It's also leaner than beef with more protein per calorie. If you like a good beef burger, these will feel familiar but a little more special.

Why are my bison burgers dry?

Almost always overcooking. Bison is much leaner than beef, so it has less fat to keep it moist. Pull the burgers at 140 to 145°F for medium, and use the grated onion and egg in this recipe, both of which add moisture that lean meat doesn't have on its own.

Can I air fry bison burgers?

Yes. Preheat the air fryer to 375°F and cook the patties about 5 minutes, flip, then 3 to 4 more minutes, until they hit 140 to 145°F for medium. The air fryer is a great hands-off option, just check the temp early since lean bison cooks fast.

How long do you cook bison burgers?

About 4 to 5 minutes per side over medium to medium-high heat, but go by temperature, not the clock. Every grill and skillet runs differently, so an instant-read thermometer is the most reliable way to nail it.

Are these bison burgers gluten-free?

The patties are naturally gluten-free; just skip the bun or use a gluten-free one. Double-check your Dijon mustard, since a few brands add gluten.

Can I make these bison burgers dairy-free?

Yes, just leave out the feta. The grated onion and egg still keep the patties juicy, so you don't lose the texture.
