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 (4 oz)
• 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 (240 ml) 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.
FAQ
Q: What is a chaffle
A: A chaffle is a keto-friendly waffle made from two simple ingredients: cheese and egg. It creates a delicious, savory, and sturdy low-carb alternative to bread, perfect for sandwiches.
Q: How do I make my chaffles extra crispy
A: For the crispiest chaffles, cook them for 3-5 minutes until golden brown. After removing them from the waffle maker, let them rest on a wire cooling rack for a minute. This allows steam to escape and prevents them from getting soggy.

Pro Tips
- Let the chaffles rest on a wire rack for a minute after cooking so steam escapes and they stay crisp under the warm fillings.
- A mix of mozzarella and cheddar gives a chewier texture to the chaffles, while a pinch of Parmesan adds a nutty note.
- Do not overfill the waffle maker — a little less than you think is usually the perfect amount to prevent overflow and cook evenly.
- Fry the eggs sunny-side up, over-easy, or over-medium so the yolk stays saucy inside the sandwich.
- Make a large batch of chaffles ahead and store them in the fridge or freezer; a toaster or air fryer brings them back in minutes.
Frequently Asked Questions
Is this breakfast sandwich keto?
Yes — each sandwich has 3 g of carbs with 35 g of protein, and the 'bread' is cheddar-and-egg chaffles with no flour.
Can I meal-prep the chaffles?
That is the best way to run this recipe — make a big batch, refrigerate or freeze it, and reheat in a toaster or air fryer each morning.
Why did my chaffles overflow?
The maker was overfilled. The cheese-and-egg batter spreads as it cooks, so keep each scoop modest and centered on the plates.
What cheese works best for these chaffles?
Cheddar is the classic choice; a mozzarella-cheddar mix makes them chewier and a pinch of Parmesan brings a nutty flavor.
