Breakfast

March 9, 2026

Say goodbye to boring low-carb breakfasts and hello to your new morning obsession! This Keto Chaffle Breakfast Sandwich packs all the savory goodness of a classic breakfast sandwich—crispy bacon, gooey cheese, and a perfectly fried egg—all nestled between two golden, cheesy chaffles. It’s ridiculously easy, incredibly satisfying, and ready in under 10 minutes. Who said keto had to be complicated?

Ingredients

• Yields: 2 Sandwiches
• For the Chaffles
• Shredded Cheddar Cheese – 1 cup / 113g
• Large Eggs – 2
• For the Sandwich
• American Cheese – 2 slices
• Bacon – 4 strips
• Large Eggs – 2

Instructions

1. Preparation Method
2. Preheat your mini waffle maker. Once hot, lightly grease the plates with butter or a non-stick cooking spray.
3. In a small bowl, whisk together 2 large eggs and the 1 cup of shredded cheddar cheese until well combined. The mixture will be thick.
4. Pour half of the cheese and egg mixture onto the hot waffle maker, close the lid, and cook for 3-5 minutes, or until golden brown and crispy. Carefully remove the chaffle and repeat with the remaining mixture to make a second chaffle.
5. While the chaffles cook, fry the bacon strips in a skillet over medium heat until your desired level of crispiness is reached. Transfer to a paper towel-lined plate to drain excess grease.
6. In the same skillet, fry the remaining 2 eggs to your preference (sunny-side up, over-easy, or over-medium work best).
7. Assemble your sandwiches: Place one chaffle on a plate, top with a slice of American cheese, two strips of crispy bacon, a fried egg, and finally, the second chaffle. Serve immediately and enjoy!

Pro Tips

• For extra crispy chaffles, let them rest on a wire cooling rack for a minute after removing them from the waffle maker. This allows steam to escape and prevents them from getting soggy.
• Don’t overfill your waffle maker! A little less than you think is usually the perfect amount to prevent overflow and ensure even cooking.
• Feel free to experiment with different cheeses. A mix of mozzarella and cheddar creates a chewier texture, while a pinch of parmesan adds a nutty flavor.
• Make a large batch of chaffles ahead of time and store them in the fridge or freezer. Reheat in a toaster or air fryer for a quick and easy breakfast base.
