Kitchen Equipment

Mini waffle maker
Mixing bowls

Spatula
Measuring cups
Whisk

Step 1: Make the Chaffle Batter

In a medium mixing bowl, whisk the eggs until smooth.

Add:

Mozzarella cheese
Almond flour
Baking powder
Garlic powder
Onion powder
Paprika
Salt

Mix until everything is evenly combined.

The batter will be thick because of the cheese.

Step 2: Cook the Chaffles

Preheat your waffle maker.

Lightly grease it with cooking spray or butter.

Spoon about one-quarter of the batter into the waffle maker.

Close the lid and cook for about 4–5 minutes until golden brown and crispy.

Repeat until you’ve made four chaffles.

Let them cool for a few minutes so they become crisp.

Step 3: Prepare the Burger Patties

Divide the ground beef into two equal portions.

Shape each into a burger patty slightly larger than the chaffles.

Season both sides with:

Salt
Pepper
Garlic powder
Onion powder

If using Worcestershire sauce, mix it into the beef before forming the patties.

Step 4: Cook the Burgers

Heat a cast-iron skillet over medium-high heat.

Cook each burger for about 4–5 minutes per side.

For medium doneness, cook until the internal temperature reaches 160°F (71°C).

During the last minute of cooking, add a slice of cheddar cheese if desired.

Remove from heat and let the burgers rest for 5 minutes.

Step 5: Make the Garlic Sauce

In a small bowl, combine:

Mayonnaise
Sour cream
Dijon mustard
Lemon juice
Garlic

Mix until smooth.

Season with salt and pepper.

Refrigerate until ready to serve.

Step 6: Assemble the Burger

Place one crispy chaffle on a plate.

Spread a generous spoonful of garlic sauce.

Add the beef patty.

Top with:

Pickles
Bacon
Jalapeños
Lettuce
Tomato
Avocado

Spread more garlic sauce on the second chaffle.

Place it on top.

Serve immediately while warm.

Pro Tips

Use freshly shredded mozzarella for the crispiest chaffles.

Don’t overwork the beef while forming patties.

Reheat in an air fryer or skillet for the crispiest results.

Frequently Asked Questions

Can I make the chaffles ahead of time?

Yes. Prepare them up to three days in advance and reheat in a toaster or air fryer for maximum crispiness.

Can I use ground turkey instead of beef?

Absolutely. Ground turkey, chicken, or even plant-based patties work well with this recipe.

Are chaffles gluten-free?

Yes. Since they’re made with eggs, cheese, and almond flour, they’re naturally gluten-free.

Can I freeze the chaffles?

Yes. Freeze them in a zip-top bag with parchment paper between each chaffle. Reheat directly from frozen in a toaster or air fryer.

What cheese works best?

Mozzarella creates a neutral, crispy bun, but cheddar, Monterey Jack, or Colby Jack also taste great.
