If you love burgers but want a low-carb alternative to traditional buns, the chaffle burger is the perfect solution. A “chaffle” is a waffle made primarily with cheese and eggs, creating a crispy, savory base that works beautifully as burger buns. This recipe is easy, satisfying, and packed with flavor. Whether you are following a keto lifestyle or simply looking for a fun twist on burgers, this chaffle burger recipe will quickly become a favorite.

What Is a Chaffle?

A chaffle combines shredded cheese and eggs cooked in a waffle maker until golden and crisp. The result is a sturdy, flavorful waffle that can replace bread in sandwiches and burgers. Chaffles are popular because they are gluten-free, low in carbs, and highly customizable.

For this recipe, the chaffles act as burger buns, sandwiching a juicy beef patty, melted cheese, fresh vegetables, and your favorite sauces.

Ingredients

For the Chaffles

• 1 cup shredded mozzarella cheese
• 2 large eggs
• 2 tablespoons almond flour
• 1/2 teaspoon baking powder
• 1/2 teaspoon garlic powder
• 1/4 teaspoon salt

For the Burger Patties

• 1 pound ground beef
• 1 teaspoon onion powder
• 1 teaspoon garlic powder
• Salt and black pepper to taste
• 1 tablespoon olive oil

Burger Toppings

• 4 slices cheddar cheese
• Lettuce leaves
• Tomato slices
• Pickle slices
• Thinly sliced onions

Burger Sauce

• 2 tablespoons mayonnaise
• 1 tablespoon ketchup
• 1 teaspoon mustard
• 1 teaspoon pickle relish

Equipment Needed

• Waffle maker
• Mixing bowls
• Spatula
• Skillet or grill pan

Step 1: Prepare the Chaffle Batter

In a medium mixing bowl, whisk together the eggs until fully combined. Add the shredded mozzarella cheese, almond flour, baking powder, garlic powder, and salt. Stir everything together until a thick batter forms.

The almond flour helps provide structure while the baking powder gives the chaffles a lighter texture. Garlic powder adds extra savory flavor that pairs perfectly with burgers.

Let the batter rest for about 2 minutes while the waffle maker heats up.

Step 2: Cook the Chaffles

Preheat your waffle maker according to the manufacturer’s instructions. Lightly grease it with cooking spray or a small amount of oil to prevent sticking.

Scoop a portion of the batter into the center of the waffle maker. Spread it slightly but avoid overfilling because the batter expands during cooking.

Close the lid and cook for 3–5 minutes, or until the chaffles are golden brown and crispy on the outside.

Carefully remove the cooked chaffle and place it on a cooling rack. Repeat until you have four chaffles, which will create two burgers.

Allowing the chaffles to cool slightly helps them crisp up even more.

Step 3: Make the Burger Patties

Divide the ground beef into two equal portions and shape them into burger patties slightly larger than the chaffles. The patties shrink a little during cooking.

Season both sides with onion powder, garlic powder, salt, and black pepper.

Heat olive oil in a skillet over medium-high heat. Cook the patties for about 4–5 minutes on each side for medium doneness. Adjust cooking time based on your preferred level of doneness.

During the last minute of cooking, place cheddar cheese slices on top of the patties and cover the pan briefly so the cheese melts perfectly.

Step 4: Prepare the Sauce

In a small bowl, mix together mayonnaise, ketchup, mustard, and pickle relish until smooth.

This sauce adds creamy tanginess that complements the rich burger and cheesy chaffles beautifully.

Step 5: Assemble the Chaffle Burgers

Place one chaffle on a plate as the bottom bun. Add a lettuce leaf, tomato slices, and the cheesy burger patty.

Top with onions, pickles, and a generous spoonful of burger sauce.

Finish with another chaffle on top.

Repeat with the second burger.

Serve immediately while the chaffles are still crisp and warm.

Tips for the Best Chaffle Burgers

1. Use Freshly Shredded Cheese

Freshly shredded mozzarella melts better and creates crispier chaffles compared to pre-packaged shredded cheese.

2. Avoid Overfilling the Waffle Maker

Too much batter can spill over the edges and prevent even cooking.

3. Crisp the Chaffles Further

If you want extra crispy chaffles, place them in a toaster or oven for a few minutes before assembling the burgers.

4. Choose the Right Beef

Ground beef with an 80/20 fat ratio creates juicy and flavorful burger patties.

Variations

Bacon Chaffle Burger

Add crispy bacon strips inside the burger for extra crunch and smoky flavor.

Spicy Jalapeño Chaffle Burger

Mix chopped jalapeños into the chaffle batter and add pepper jack cheese for heat.

Chicken Chaffle Burger

Replace beef patties with grilled chicken breasts or crispy chicken fillets.

Mushroom Swiss Chaffle Burger

Top the burger with sautéed mushrooms and Swiss cheese for a rich, savory variation.

Storage and Reheating

Chaffles can be made ahead of time and stored in an airtight container in the refrigerator for up to 4 days.

To reheat, place them in a toaster or air fryer for a few minutes to restore crispiness.

Burger patties can also be refrigerated separately and reheated in a skillet or microwave.
