Ingredients in a Chaffle BLT

You already know that veggies and bacon are keto-diet go-to ingredients.  But what’s the bread that’s holding this sandwich together?  It’s a chaffle.

A chaffle is a fantastic low-carb alternative to bread.  It’s the perfect keto swap for making delicious sandwiches. It’s made from two basic ingredients: egg and shredded cheese.  Yes, that’s it!

If you like, you can even change up the flavor of your chaffle bread by using different cheese or adding herbs and spices. And, if you want the best tasting sweet chaffles, start with a milder tasting cheese like mozzarella. You’ll have to try them out and see what you think for yourself!

How to Make Chaffles for Sandwiches

Making chaffle bread for sandwiches is easy and fast — from start to finish it will take about 5 minutes.

The only special piece of kitchen equipment you need to make these keto chaffles is a waffle maker.  Although I have made chaffles successfully in a normal size Belgian waffle maker, I’ve had a lot easier time using this Dash Mini Waffle Iron. It is the perfect size to cook them quickly.

The mini waffle maker will make 2 pieces of  bread out of 1 egg and 1/2 cup of cheese. And, the smaller size helps the chaffles get nice and crispy.
