Keto Chaffle Sandwich (Chaffwich)
Fluffy, cheesy, and low-carb, this keto chaffle sandwich (Chaffwich) is my fun twist on the keto classic. I’ve always loved experimenting with cheese and eggs on keto, but I wanted something different from the usual “eggy waffles.” That’s when I started making sandwiches in my 3-in-1 sandwich maker/waffle iron and the Chaffwich was born.
Back when I was on strict keto for fast weight loss (I’m maintaining now), I packed these for lunch, and they always made me smile. I’d open my lunchbox, and coworkers would ask why my sandwich looked so different.
No bread, just golden mozzarella-packed chaffles layered with pepperoni, bell peppers, and more melty cheese. Crispy edges, gooey center, and only 2g net carbs per serving.
If you’ve tried my Crispy Keto Chaffle Pizza, you’re going to enjoy this fun mash-up. It’s like a handheld pizza sandwich, no flour needed, and still super cheesy and satisfying.
What is a Chaffwich?
A Chaffwich is exactly what it sounds like: a chaffle sandwich. Instead of bread, you use crispy cheese-and-egg waffles (aka chaffles) as the base, then layer them with sandwich fillings like pepperoni, cheddar, turkey, or veggies. Think of it as the ultimate low-carb sandwich bread replacement.
Unlike a basic chaffle recipe, this one isn’t just for waffles with syrup, it’s savory, high-protein, and perfect for sandwiches.

Keto chaffle pizza: Chaffwich Keto Chaffle Breakfast Sandwich Pepperoni Recipe
Step-by-Step Instructions
Preparation (Making the Chaffles):
- Preheat your sandwich maker. Start with the triangle sandwich plates. Make sure they’re clean before heating to avoid burning crumbs.
- Mix the batter. In a small bowl, whisk together the eggs, shredded mozzarella, and parmesan cheese (this helps the chaffles crisp up nicely).
- Cook the chaffles. Pour the mixture evenly into the four triangle sections of the preheated sandwich plates. Close the lid and cook for 3–5 minutes, until the chaffles are golden brown and crispy.
Tip: If you only have a round Dash mini waffle maker, you can still make this recipe. The chaffles will just come out in half-moon shapes instead of triangles.
Assembly (Building the Chaffwich):
- Switch plates. Carefully change your sandwich maker plates from the triangle inserts to the panini press plates (or use any flat grill plates).
- Layer the fillings. Place two chaffles onto the panini press. Add your fillings: pepperoni slices, chopped bell pepper, spring onions, and a sprinkle of shredded cheese.
- Top and press. Add two more chaffles on top to make a sandwich. Close the lid and press down gently. Cook for 2–3 minutes, until the cheese melts and everything is warmed through.
- Serve hot or cold. Slice and enjoy your melty, crispy Chaffwich!

Tips for the Perfect Chaffwich
- Use shredded mozzarella, not fresh. Fresh mozzarella is too wet and will make soggy chaffles.
- Always preheat your waffle maker. Cold plates = uneven, soft chaffles.
- Don’t overload with fillings. Too many toppings can weigh down the sandwich and soften the texture.
- No waffle maker? Use a skillet and press down with a spatula for a “flat chaffle sandwich.”
Storage & Reheating
- Fridge: Store leftover chaffwiches in an airtight container in the fridge for up to 3 days.
- Freezer: Wrap individually in parchment paper and freeze in a zip-top bag for up to 2 months.
- Reheating: Reheat in a panini press, oven, or air fryer at 350°F (175°C) for 5–7 minutes until crispy again. Avoid the microwave, it makes the chaffles soft instead of crispy.
Swaps & Variations
- Meat swaps: Use turkey pepperoni, deli ham, cooked bacon, or shredded chicken instead of pepperoni.
- Cheese swaps: Any dry shredded cheese works – cheddar, gouda, or even a Mexican blend will all give a different flavor. Just avoid fresh mozzarella (too much moisture).
- Veggies: Try spinach, mushrooms, or zucchini instead of bell peppers for more variety.
- Sauce option: Spread a thin layer of sugar-free marinara or mustard between the layers for extra flavor.
Serving Ideas
- Classic breakfast sandwich – Add bacon, egg, and cheddar cheese
- Turkey club chaffle – Layer with deli turkey, lettuce, tomato, and mayo
- Veggie option – Use spinach, mushrooms, and bell peppers for a meat-free version
Final Thoughts
The Chaffwich is more than just a keto chaffle sandwich—it’s a fun, cheesy, low-carb meal that makes keto exciting again. Whether you pack it for lunch, enjoy it as a keto breakfast sandwich, or serve it as a quick dinner, it’s guaranteed to impress.
FAQ
Q: Can I make this in a Dash mini waffle maker?
A: Yes! Just divide the batter into smaller portions and cook in batches.
Q: What’s the perfect size for a chaffle, and which waffle iron should I use?
A: The perfect size for a chaffle is usually small and thick, similar to traditional waffles. A mini dash waffle maker or a Belgian waffle maker can be used, depending on your preference for chaffle thickness.
Q: Can I make chaffles without a waffle maker?
A: Absolutely! While a mini waffle iron is ideal, you can use a regular waffle maker or even an air fryer with a baking sheet to make chaffles. Just pour the chaffle batter onto the appliance and cook until crispy.
Q: How can I ensure my chaffles are crispy and not soggy?
A: To get that perfect crispy texture, cook your chaffles on medium heat until they’re golden brown. Let them cool on an oven rack in a single layer to prevent steam from making them soggy.
