Ingredients
For the Chaffles
- 2 cups shredded mozzarella cheese
- 4 large eggs
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon salt
- ¼ teaspoon black pepper
For the Burger Patties
- 1 pound (450g) ground beef (80/20 blend)
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon Worcestershire sauce
- 1 teaspoon garlic powder
Burger Toppings
- 4 slices cheddar cheese
- 1 large tomato, sliced
- 1 cup lettuce leaves
- ½ red onion, thinly sliced
- 8 pickle slices
- 2 tablespoons mayonnaise
- 1 tablespoon mustard
- 1 tablespoon sugar-free ketchup (optional)
Equipment Needed
- Waffle maker
- Mixing bowls
- Skillet or grill pan
- Spatula
- Measuring spoons
Instructions
Step 1: Prepare the Chaffle Batter
In a medium mixing bowl, whisk the eggs until smooth. Add the shredded mozzarella cheese, garlic powder, onion powder, salt, and black pepper. Stir until all ingredients are evenly combined.
Allow the mixture to rest for 2–3 minutes. This helps the cheese absorb some of the moisture from the eggs, creating a better texture.
Step 2: Preheat the Waffle Maker
Preheat your waffle maker according to the manufacturer’s instructions. Lightly spray it with non-stick cooking spray if needed.
A properly heated waffle maker ensures crispy chaffles with a golden exterior and prevents sticking.
Step 3: Cook the Chaffles
Scoop approximately ¼ cup of the chaffle mixture into the center of the waffle maker. Close the lid and cook for 3–4 minutes or until golden brown and crisp.
Carefully remove the chaffle and place it on a cooling rack.
Repeat the process until you have 8 chaffles, which will serve as the top and bottom “buns” for the burgers.
Step 4: Prepare the Burger Patties
In a bowl, combine the ground beef, salt, black pepper, Worcestershire sauce, and garlic powder.
Mix gently until just combined. Avoid overmixing, as this can make the burgers tough.
Divide the mixture into four equal portions and shape them into burger patties slightly larger than the chaffles, as they will shrink during cooking.
Step 5: Cook the Burger Patties
Heat a skillet or grill pan over medium-high heat.
Cook each patty for approximately 4–5 minutes per side for medium doneness. Adjust cooking time according to your preferred level of doneness.
During the final minute of cooking, place a slice of cheddar cheese on each patty and cover briefly to allow the cheese to melt.
Step 6: Assemble the Chaffle Burgers
Spread mayonnaise, mustard, or your preferred condiments on one chaffle.
Place a lettuce leaf on the bottom chaffle, followed by the cheeseburger patty.
Add tomato slices, red onion, and pickles.
Top with another chaffle and gently press together.
Repeat for the remaining burgers.
Step 7: Serve
Serve immediately while the chaffles are warm and crisp.
Pair with a side salad, roasted vegetables, zucchini fries, or cauliflower tots for a complete low-carb meal.
Tips for Success
Use Freshly Shredded Cheese
Pre-shredded cheese contains anti-caking agents that can affect texture. Freshly shredded mozzarella produces crispier chaffles.
Don’t Overfill the Waffle Maker
Using too much batter can cause overflow and uneven cooking. A small amount goes a long way.
Let Chaffles Cool Slightly
Cooling the chaffles on a wire rack helps maintain crispness and prevents sogginess.

Meal Prep Option
Chaffles can be prepared ahead of time and stored in the refrigerator for up to 4 days. Reheat in a toaster or air fryer before serving.
Storage Instructions
Refrigerator
Store leftover burger patties and chaffles separately in airtight containers for up to 4 days.
Freezer
Freeze cooked chaffles in a freezer-safe bag for up to 2 months. Place parchment paper between each chaffle to prevent sticking.
Reheating
Reheat chaffles in a toaster, oven, or air fryer until crispy. Avoid microwaving, as it can make them soft.
