What Is A Chaffle?

A chaffle is a savory low-carb, keto waffle that is made with just 3 ingredients and 1 net carb per waffle. They are such a great sugar-free breakfast to batch cook and reheat during the week!

This low-carb keto chaffle recipe is basic in steps and ingredients but offers endless options for added flavors, sweet or savory! Even my kids love the chaffle (which they call “cheese waffle”).

What Makes This Recipe Great?

This may sound crazy, but it totally works. Chaffles taste like super crispy, cheesy waffles, but with such a mild flavor that you could drench it in syrup and not even know the difference between these and regular waffles! Except your traditional waffle has tons of carbs, and the net carbs in these are way less!

I love using mozzarella cheese since it’s mild tasting, so it leaves the chaffle more neutral-tasting and ready for whichever toppings you choose! All you need are simple ingredients, a Belgian waffle maker (or mini waffle iron!), and your favorite toppings– the BEST!

Ingredient Notes

• Cheese: I prefer shredded mozzarella because it has the most neutral flavor, but you could also use shredded cheddar, shredded Mexican blend, parmesan cheese, etc.
• Almond Flour: You could substitute almond meal for almond flour. I would NOT recommend substituting coconut flour.
• Egg: I haven’t tried these using just eggs whites, but if you do and it works, let me know in the comments!
• Tree Nut Free: I haven’t tried it, but you should be able to use 2 teaspoons of coconut flour in place of the 2 tablespoons of almond flour. Coconut flour takes a bit to absorb, so I’d let the batter sit for 5 minutes so it can thicken properly.
• Dairy-Free: Sadly, I’m not sure this would work with dairy-free shredded cheese, such as Daiya. I don’t think these can be made dairy free. If you think of a way to make them dairy free please share in the comments!

Step-by-Step Instructions

1. Heat your waffle iron.
2. In a small bowl, combine the large egg, almond flour, and mozzarella cheese. Whisk to combine.
3. Spray the waffle iron with avocado oil spray. Pour the batter onto your waffle iron. Cook for 3-6 minutes, until the waffles are crispy and golden brown.
4. Transfer to a wire rack to cool completely. They are the crispiest when they are allowed to fully cool.

The Best Waffle Maker

I love this waffle iron because I can make up to 4 chaffles at once, and the chaffles/waffles are the perfect size to fit in a toaster oven to reheat.

This recipe is for 2 chaffles. Double the recipe if you want to make 4. Some people really like using a Dash mini waffle maker, but I like the ease of meal prep with the bigger regular waffle maker (now, a chaffle maker!).

Chaffle Toppings

• Grassfed Butter & Lakanto Sugar-Free Syrup
• Avocado & Microgreens
• Almond Butter & Keto Friendly Dark Chocolate Chips
• Fresh Berries & Keto Whipped Cream

Chaffle Flavor Variations

This is a basic chaffle recipe, but there are so many different variations and ways to spice it up! Make sweet chaffles or savory ones! Here are some fun ideas to play around with the change up the flavor profiles of your Chaffle recipe! Sometimes, the keto diet (or low carb diet) can get boring. Switching things up is a great way to make it fun!

• Pumpkin Pie Cheesecake Chaffles: canned pumpkin, cream cheese, cinnamon & pumpkin pie spice.
• Blueberry Chaffles: fresh blueberries, cinnamon, monk fruit sweetener.
• Chocolate Chaffles: cacao powder, dark chocolate chips, monk fruit sweetener.
• Spinach Chaffles: add in a handful of raw chopped spinach, and shredded cheddar cheese.
• Maple Bacon Chaffles: keto-friendly maple syrup, chopped cooked bacon.
• Pizza Chaffles: pizza sauce, pepperoni.
• Avocado Toast Chaffle: mashed avocado, sliced tomatoes, olive oil, everything but the bagel seasoning, or garlic powder. 

Expert Tips

• Toppings: I love my keto chaffle topped with mashed avocado and some micro greens. It is literally the most perfect keto avocado toast I have had in my entire life. But really, the possibilities are kind of endless. I’m even dreaming of using these as sandwich bread, or a bun for burgers. 
• Texture: The texture is a super crisp exterior with a light and airy interior. Also, the almond flour helps give it a little more body and keeps it substantial. The egg gives it rise and those perfect bubbles you see, and the cheese helps it get crispy.
• To get your keto chaffle extra crispy, which is of course my favorite, a waffle has to have CRISP, you want to let them cool fully on a wire rack. The wire rack prevents steam from accumulating on the bottom and causing soggy waffle bottoms. Let them cool down for a good 3-5 minutes so they aren’t soft and eggy.
• Reheating: Best part? You can freeze and reheat chaffles right in the toaster, just like eggo waffles. So you can easily batch cook a bunch and always have a speedy breakfast waiting for you in the freezer. You can also reheat in your air fryer if desired.
