Ingredients in Chaffle Breakfast Sandwiches

This recipe for keto breakfast sandwiches made with chaffles requires relatively few ingredients. For the chaffles themselves, you’ll only need two ingredients:

  • 1 large egg
  • 1/2 cup of shredded cheese

This will make enough chaffle batter for 2 mini chaffles — or the two “buns” of our breakfast sandwich.

Then, for the filling of the sandwich, you can choose between all sorts of keto-friendly ingredients.  In this version, I’ve used

  • thick-cut bacon
  • fried egg
  • sliced cheese

But this recipe would also be great with:

  • sausage
  • ham
  • scrambled eggs
  • sliced avocado
  • sauteed mushroom and peppers
  • hot sauce, etc!

How to Make Keto Breakfast Sandwiches with Chaffles

The first thing you’ll need to do to make chaffle breakfast sandwiches is to make your chaffle “bread”.  Luckily, making chaffles is so quick and easy.  Start to finish, it takes less than 5 minutes.

A keto chaffle is a waffle made from two basic ingredients: egg and shredded cheese.  For a chaffle breakfast sandwich, I like to use Cheddar cheese.  But you can use any shredded cheese you like.

The only piece of kitchen equipment you need to make these keto chaffles is a waffle maker. I’ve made chaffles successfully in a normal size Belgian waffle maker. And, I’ve made smaller size chaffles in a mini waffle maker.

But, I’ve had the most success using this Dash Mini Waffle Iron to cook chaffles. It is the perfect size to cook them quickly and make them crispy.

Then, after the chaffle “bread” is ready, you can fill your sandwich with any toppings you like.  For this recipe, I’ve used crispy thick-cut bacon and a fried egg.  But you can switch it up with sausage, ham, scrambled eggs, avocado, hot sauce, etc.  It’s really up to you!

Variations on the Chaffle Recipe

You can add all sorts of flavorings to plain chaffle batter to create new types of chaffles.

  • Try experimenting with different kinds of cheese.  Cheddar is the original flavor, but I also like to use Monterrey Jack, Colby, mozzarella cheese, etc.
  • Add spices such as garlic powder, Italian seasoning, Everything But the Bagel seasoning, or assorted herbs.
  • For a sweet “McGriddle” type of chaffle, use mild mozzarella cheese, and add 1 tsp or 2 of sugar-free maple syrup to the batter.
  • For even lighter chaffles, you can add a teaspoon of coconut flour or a tablespoon of almond flour to the egg mixture.  For the ultimate fluffiest chaffles, add 1/4 tsp baking powder and a pinch of salt.

  2. I am newly diabetic and now new to Keto and your recipes have me excited! I am not a fan of many vegetables to this is a challenge I am trying to overcome. I have a question on your light fluffy chaffes…. It says “For even lighter chaffles, you can add a teaspoon of coconut flour or a tablespoon of almond flour to the egg mixture.” Are these ingredients instead of the cheese and if so are they more like a “bread”? Thank you in advance and thank you for helping me get excited about getting healthy.

  5. I don’t understand, where are 6g of carbs coming from in this? Bacon, egg and cheese are all 0 carb. You *might get some carbs from the cheddar if you use pre-shredded but I don’t think 6g…
