Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Egg

The egg acts as the binding element of the chaffel, giving structure while contributing protein. It ensures the waffle cooks evenly and holds together during assembly.

Shredded Cheese

Cheese is the star component of any chaffle. It creates the crisp edges and chewy interior characteristic of this keto favourite. Cheddar, mozzarella, or a blend all work well.

Almond Flour

Almond flour provides body and a bread-like texture, helping the chaffel feel more substantial. It keeps the recipe low in carbs and gluten-free.

Baking Powder

A small amount of baking powder adds lift, creating a lighter and more airy chaffel.

Cream Cheese

Cream cheese enriches the batter, providing smoothness and a subtle tang. It also helps the chaffel stay moist without becoming soggy.

Salt and Pepper

Basic seasoning elevates the overall flavour profile and brings balance to the richness of the cheese and cream cheese.

Butter

A light buttering of the waffle iron prevents sticking while adding a hint of richness and helping the chaffel achieve its crisp golden finish.

Sandwich Fillings

Typical fillings include deli turkey or ham, sliced cheese, lettuce, tomatoes, or even bacon and avocado. These transform the chaffel into a complete, satisfying meal.

Directions

Begin by preheating your waffle maker. Lightly butter the plates to prevent sticking and help achieve a crisp exterior. In a small bowl, whisk together the egg, softened cream cheese, and shredded cheese until well combined. Add the almond flour, baking powder, salt, and pepper. Stir until the mixture forms a smooth, cohesive batter.

Pour half the batter onto the heated waffle maker and spread it lightly toward the edges. Close the lid and cook for three to four minutes, or until the chaffel turns a deep golden brown and lifts easily from the plates. Repeat with the remaining batter to create the second chaffel. Allow them to cool briefly on a wire rack; this step helps maintain crispness.

Assemble your sandwich by layering your chosen fillings between the two chaffels. Classic combinations like turkey and cheese, ham and tomato, or bacon with lettuce and avocado work exceptionally well. Slice and serve immediately for best texture. If preparing for later, cool the chaffels completely before assembling to avoid steam softening the layers.

Servings and timing

This recipe yields 1 sandwich (2 chaffels). Preparation and cooking together take approximately 10 minutes. Assembly takes an additional 2 minutes, making this a quick and efficient low-carb meal.

Storage/reheating

Chaffels store well when cooled completely. Place them in an airtight container and refrigerate for up to three days. To reheat, toast them in a toaster or air fryer to restore crispness. Avoid microwaving, as it softens the texture. Assembled sandwiches are best enjoyed fresh, but you may store the components separately and assemble just before eating.
