Low Carb BLT Chaffles – Keto Recipe

by Alli

Low Carb BLT Chaffles are so delicious! Eggs and mozzarella cheese are cooked in a waffle iron until crisp. Add mayo, bacon, lettuce, and tomato, and make a sandwich – just like a regular BLT. The chaffle takes the place of the bread!

What in the world is a chaffle?

A chaffle is a low-carb “waffle” made with eggs and cheese. Cheese plus eggs cooked in a waffle iron equal chaffles! 

If you’re doing low-carb or keto, you will love these chaffles. I’m a BLT lover but I’m trying to cut back on bread so these are just the thing to satisfy my BLT cravings.

Ingredients For BLT Chaffles 

  • mozzarella cheese
  • eggs
  • bacon
  • tomato
  • lettuce
  • mayonnaise 
  • salt and pepper

How To make BLT Chaffles

To make BLT Chaffles, I use a Presto Waffle Flip-Side Waffle Maker. I linked it down below in the recipe card. 

Preheat waffle iron. Spread half the cheese on the iron. Pour the beaten eggs over the cheese. Top with remaining cheese. Close iron and cook until steam stops (about 5 minutes) and the chaffle is crispy.

Questions About BLT Chaffles

  • Does the chaffle taste like eggs? No, they really don’t. I can smell the eggs while they are cooking but the chaffles come out light and fluffy. (I’m not much of an egg person and I promise these do not taste eggy at all.) 
  • How do I know when the chaffle is done? I cook mine for 5 minutes, about the same time the waffle iron stops steaming. 
  • Can I use a mini waffle maker? Yes! Just pour half of the batter in when making a chaffle. 
  • Can this recipe be doubled? This recipe makes one chaffle. You can make as many chaffles as you need. Each chaffle is made with 2 beaten eggs and 1/2 cup mozzarella cheese. Make sure the chaffle is cooked until crispy. 
  • I’ve found that if you mix the eggs and cheese together before cooking, it just doesn’t taste as good. It’s best to follow the directions on the recipe card. 
Yield: one serving
