Step-by-Step Instructions

Prepare the tuna filling – Mix drained tuna, mayonnaise, Dijon mustard, celery, red onion, lemon juice, salt, and pepper until creamy and evenly combined.

Make the chaffle mixture – Whisk shredded cheese, eggs, garlic powder, onion powder, salt, and pepper until cohesive and thick.

Preheat the waffle maker – Heat according to manufacturer directions to ensure crisp browning and easy release.

Cook the chaffles – Lightly grease the waffle maker, add half the batter, and cook 3–5 minutes until golden and crisp; repeat with remaining batter.

Assemble the sandwich – Place tuna mixture on one chaffle, sprinkle with shredded cheese, and top with the second chaffle.

Melt the topping cheese – Return briefly to the waffle maker or broil until cheese is bubbly and fully melted.

Cool slightly and serve – Rest briefly for cleaner slicing, then cut and enjoy warm.

Use finely shredded cheese – Helps the chaffle bind and crisp evenly.
Avoid overfilling – Keeps the sandwich stable and easy to melt.

Why This Recipe Works

This recipe succeeds by leveraging the structural properties of melted cheese and coagulated egg proteins to replace traditional bread. The chaffle crisps through fat rendering and surface browning, creating stability for the creamy tuna mixture. Acid from mustard and lemon balances the richness of mayonnaise and cheese, preventing palate fatigue. Because it’s naturally low in carbohydrates yet high in protein and fat, the dish delivers sustained fullness with moderate calories compared to conventional tuna melts.
