Ingredients
(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)
Canned tuna is the main protein source. It provides a rich, savory flavor and works perfectly with creamy and cheesy elements.
Egg is essential for binding the chaffle batter. It helps create structure and gives the waffle its signature texture.
Shredded mozzarella cheese forms the base of the chaffle, creating a crispy exterior and a soft, cheesy interior.
Mayonnaise adds creaminess to the tuna mixture and enhances the overall richness.
Cheddar cheese is used for the melt, adding a sharp and bold flavor that pairs beautifully with tuna.
Dijon mustard brings a slight tang that balances the richness of the cheese and mayo.
Salt enhances the overall flavor and ensures the dish is well seasoned.
Black pepper adds a mild kick and complements the savory ingredients.
Garlic powder adds depth and a subtle savory boost.
Directions
Preheat your waffle maker and lightly grease it to prevent sticking. This ensures the chaffle cooks evenly and releases easily.
In a bowl, whisk together the egg and shredded mozzarella cheese until well combined. This forms the base of your chaffle batter.
Pour half of the mixture into the waffle maker and cook for about 3 to 4 minutes, or until golden and crisp. Repeat with the remaining batter to make a second chaffle.
While the chaffles are cooking, prepare the tuna filling. In a bowl, combine the drained tuna, mayonnaise, Dijon mustard, salt, black pepper, and garlic powder. Mix until smooth and creamy.
Place one chaffle on a flat surface and spread the tuna mixture evenly over it. Top with cheddar cheese, then place the second chaffle on top to form a sandwich.
Return the assembled chaffle to the waffle maker or a skillet and heat until the cheese melts and the sandwich is warmed through.
Serve immediately while hot and crispy for the best texture and flavor.

Storage/reheating
Store any leftover components separately in airtight containers in the refrigerator for up to 2 days. The chaffle may soften slightly over time.
To reheat, place the chaffle in a skillet or toaster oven until it becomes crisp again. Avoid microwaving if possible, as it can make the texture soft.
The tuna filling can be made ahead and stored, making this recipe even quicker to assemble when needed.
Variations and Customizations
Tuna Melt Chaffles are incredibly versatile, allowing you to adjust flavors based on your preferences. One simple variation is to add finely chopped celery or red onion to the tuna mixture. This adds a refreshing crunch and enhances the texture of the filling.
For a spicier version, mix in a dash of hot sauce or a pinch of chili flakes. This creates a bold contrast with the creamy tuna and melted cheese. I once added a bit of sriracha, and it gave the sandwich a pleasant heat that balanced the richness perfectly.
You can also experiment with different cheeses. Pepper jack adds spice, while Swiss cheese offers a milder, nutty flavor. Each variation changes the overall profile of the dish in an interesting way.
If you want to lighten the recipe, substitute mayonnaise with Greek yogurt. This keeps the filling creamy while reducing fat content. You can also add fresh herbs like parsley or dill for a brighter, fresher taste.
For added nutrition, consider layering in slices of tomato or spinach. These additions bring freshness and balance to the richness of the chaffle. You can even turn this into an open-faced version by using just one chaffle and topping it generously.
