Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Start by preheating your mini waffle maker. This is essential for achieving the crispy exterior that makes chaffles so delicious. While it's heating, crack one egg into a small bowl and whisk until smooth.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Add the shredded mozzarella, almond flour, garlic powder, and salt to the whisked egg. Mix thoroughly until well combined. The almond flour adds structure while the cheese provides both flavor and helps create that satisfying crispy exterior when cooked.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Once your waffle maker is hot (most have an indicator light), lightly coat with non-stick spray if needed. Pour half of the chaffle mixture into the center of the waffle maker and close the lid. Cook for about 3-4 minutes until golden brown and crispy. The edges should be slightly darker, which indicates a perfectly crisp chaffle.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Carefully remove the first chaffle to a plate and repeat the process with the remaining batter to make your second chaffle. These will serve as your sandwich "bread." Allow both chaffles to cool slightly, which will help them firm up and become more bread-like in texture.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>While your second chaffle is cooking, heat a small non-stick frying pan over medium heat and add the butter. Once melted, crack your remaining egg into the pan. For a sandwich-style egg, you can break the yolk and slightly spread the egg, or for a more traditional style, leave the yolk intact.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Cook the egg until the whites are set but the yolk is still slightly runny (if preferred), about 2-3 minutes. Carefully flip the egg and place the sliced cheddar on top. Cook for another 30 seconds until the cheese begins to melt.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Assemble your sandwich by placing the cooked egg with melted cheese on one chaffle. Top with the cooked bacon slices, and any optional ingredients like avocado or a dash of hot sauce. These additions provide healthy fats and flavor contrast.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Complete your sandwich with the second chaffle and press gently to help everything adhere. The residual heat will continue to melt the cheese, creating that perfect breakfast sandwich texture. For an extra-crispy experience, you can briefly return the assembled sandwich to the waffle maker and press gently for 30 seconds.</li></ol>

What ingredients are used in Keto Breakfast Sandwich (Chaffle Bread) Recipe?

The main ingredients include eggs, shredded mozzarella, almond flour, garlic powder, salt, cheddar cheese, bacon, and butter. Optional additions include avocado slices and hot sauce. These simple ingredients create a low-carb breakfast alternative with only 3g of carbs.

How to cook Keto Breakfast Sandwich (Chaffle Bread) Recipe at home?

Learn how to cook Keto Breakfast Sandwich (Chaffle Bread) Recipe by first making chaffles in a mini waffle maker using a mixture of egg, mozzarella and almond flour. While they cook, prepare your filling by frying an egg and cooking bacon until crispy. Then simply assemble by layering the egg, cheese, and bacon between your crispy chaffles for a quick, satisfying low-carb meal.

What makes chaffles crispy on the outside but soft inside?

The combination of cheese and egg creates the perfect chaffle texture. Cheese melts then crisps up against the hot waffle maker surfaces, while the egg provides structure and softness inside. Allowing chaffles to cool for 1-2 minutes after cooking helps them firm up for the ideal bread-like consistency.

Can I make chaffle sandwiches in advance for meal prep?

Absolutely! Prepare the chaffles ahead of time and store in an airtight container in the refrigerator for 2-3 days. For best results, reheat them in a toaster or air fryer to restore crispiness before assembling your sandwich. You can even freeze them for up to a month.

What are the best low-carb toppings to customize my breakfast sandwich?

Popular low-carb additions include avocado, sautéed spinach, mushrooms, hollandaise sauce, smoked salmon, cream cheese, jalapeños, different cheese varieties, pesto, or sugar-free ketchup. These additions maintain the keto-friendly profile while offering variety and additional nutrients.
