This recipe keeps things low-carb, high-flavor, and is simple enough for a weekday but fancy enough to impress on the weekend. Let’s jump in and turn that wild game meat into the burger of your dreams.

Why Game Meat?

Game meat like venison, bison, or elk has a rich, earthy flavor you can’t quite get with beef. It’s leaner, meaning fewer calories and more protein, and it’s packed with nutrients like iron and omega-3s. Plus, if you’re on keto, it fits perfectly into your low-carb lifestyle. Just remember: because it’s lean, you’ll want to add a little fat to keep things juicy.

Ingredients

This recipe makes 4 hearty burgers. You can double it if you’re feeding a crowd—or just really hungry.

For the Burgers

• 1 lb ground game meat (venison, elk, bison, or a mix)
• 1/4 cup pork fat or beef tallow (for moisture and flavor)
• 1 tsp garlic powder
• 1 tsp onion powder
• 1/2 tsp smoked paprika (optional, for a smoky kick)
• 1 tsp salt
• 1/2 tsp black pepper
• 1 egg (helps bind the mixture)

For the Caramelized Onions

• 2 medium yellow onions, sliced thin
• 2 tbsp butter (grass-fed if possible)
• 1/2 tsp salt
• 1/2 tsp erythritol or monk fruit sweetener (optional, to mimic the sweetness of regular caramelized onions)

Toppings & Assembly

• Lettuce leaves (for wrapping)
• Keto-friendly burger buns (optional, but there are great low-carb brands out there)
• Sliced avocado
• Sugar-free pickles
• Dijon or spicy mustard
• Cheese (cheddar, Swiss, or Gouda work well—choose a good melty one)

Step-by-Step Instructions

Step 1: Prep Your Meat

In a large bowl, combine the ground game meat, pork fat, egg, garlic powder, onion powder, paprika, salt, and pepper. Don’t overmix—it can make the meat tough. Just use your hands (or a spoon, if you’re squeamish) to gently bring it all together.

Divide the mixture into four equal parts and form into patties about 3/4 inch thick. Make a little dent in the center of each patty with your thumb; this helps them cook evenly.

Pro tip: Chill the patties in the fridge for 20 minutes before cooking. This helps them hold their shape and keeps them extra juicy.

Step 2: Caramelize Those Onions

Heat a skillet over medium heat and add the butter. Once it’s melted, toss in the sliced onions and sprinkle with salt. Stir them around to coat in the buttery goodness.

Turn the heat to low and let the onions cook slowly, stirring every 5–7 minutes. They’ll start to turn golden brown and soft after about 20–25 minutes. If you’re using a sweetener, add it in the last 5 minutes of cooking.

Shortcut: Don’t rush this part—caramelizing onions takes time, but the sweet, rich flavor they bring is worth the wait.

Step 3: Cook the Burgers

Heat a grill or skillet over medium-high heat. If you’re using a skillet, add a little oil to prevent sticking.

Cook the burgers for about 4–5 minutes per side, depending on your preferred doneness. Game meat is best cooked medium or medium-well to avoid dryness.

Cheese fans: Add your cheese during the last minute of cooking and cover the skillet or grill to help it melt.

Step 4: Assemble Like a Pro

Now for the fun part! Lay down a lettuce leaf or keto bun, then stack on your patty. Top it with a generous scoop of caramelized onions, a few slices of avocado, pickles, and a dollop of mustard. Feel free to go wild with your toppings—jalapeños, crispy bacon, or even a fried egg would be amazing here.

Tips to Nail the Perfect Keto Game Meat Burgers

• Don’t Skip the Fat
  Game meat is lean, which can make burgers dry. Adding pork fat, beef tallow, or even a bit of bacon grease keeps them juicy and flavorful.
• Go Low and Slow on the Onions
  Yes, caramelizing onions takes patience, but the flavor payoff is huge. Resist the urge to crank up the heat; you’ll end up with burnt, bitter onions instead of sweet, golden ones.
• Customize Your Seasoning
  The recipe keeps things simple, but feel free to experiment. A dash of Worcestershire sauce or a sprinkle of fresh herbs can totally change the vibe.
• Rest Your Patties
  Letting your burgers rest for a couple of minutes after cooking helps the juices redistribute, making for a juicier bite.

What to Serve with Your Keto Burgers

These burgers are pretty filling on their own, but a good side dish rounds out the meal. Here are a few ideas:

• Zucchini Fries: Crispy, cheesy, and totally keto-friendly.
• Cauliflower Salad: Like potato salad, but without the carbs.
• Pickled Veggies: Tangy and crunchy—they cut through the richness of the burger beautifully.
• Portobello Mushroom Caps: Use these as a bun alternative or grill them for a side.

Why These Burgers Work for Keto

Every bite of this burger is a keto win. The game meat is high in protein, the onions are sweetened without sugar, and the toppings keep the carb count low. Even if you’re using keto-friendly buns, you’ll stay well within your daily limits.

Here’s a rough breakdown of macros per burger (without the bun):

• Calories: 320
• Fat: 22g
• Protein: 25g
• Carbs: 6g (mainly from the onions)

Storage and Leftovers

If you’ve got extra patties, store them in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet to keep them from drying out.

For caramelized onions, pop them in a jar and refrigerate. They’re great for meal prep and will last up to a week. Use them on eggs, salads, or even as a dip for celery sticks.
