Step-by-Step Preparation
Step 1: Make the Chaffle
- Preheat your mini waffle maker.
- In a small bowl, whisk the egg until smooth.
- Mix in shredded cheddar, almond flour, baking powder, salt, and pepper until fully combined.
Step 2: Cook the Chaffle
- Pour the batter into the preheated waffle maker.
- Cook for 3–4 minutes until golden brown and crisp.
- Carefully remove and let cool slightly on a plate.
Step 3: Prepare the Tuna Topping
- In a small bowl, combine the drained tuna, mayonnaise, Dijon mustard, red onion, parsley, salt, and pepper.
- Mix until well combined and creamy.
Step 4: Assemble the Tuna Melt
- Spread the tuna mixture evenly over the cooked chaffle.
- If desired, top with an extra slice of cheddar cheese.
- Broil in the oven for 1–2 minutes until the cheese is melted and bubbly.
Step 5: Serve & Enjoy
Serve warm as a protein-packed snack or light meal. For added freshness, garnish with extra parsley or a squeeze of lemon.
Tips for Perfect Chaffles
- Crispier Texture: Let the chaffle sit in the waffle maker for an extra 30 seconds before removing to ensure crispiness.
- Cheese Choice: Sharp cheddar gives more flavor, but mozzarella or gouda works well too.
- Prevent Sticking: Lightly grease the waffle maker if needed.
- Make Ahead: You can cook multiple chaffles in advance and refrigerate or freeze for later use. Reheat in the toaster or air fryer for best results.
- Extra Flavor: Add smoked paprika, garlic powder, or a pinch of cayenne to the chaffle batter for a flavor boost.
Variations
- Tuna Salad Mix-ins: Add chopped celery, pickles, or capers for crunch and tang.
- Avocado Topping: Mash avocado into the tuna mixture for creaminess and healthy fats.
- Open-Faced or Sandwich: Use two chaffles for a full sandwich-style tuna melt.
- Cheese Variations: Pepper jack, Swiss, or provolone can be substituted for cheddar.

Frequently Asked Questions (FAQ)
1. Can I make this vegetarian?
Yes! Substitute the tuna with chickpea salad or mashed white beans for a vegetarian version.

Absolutely! The batter can be doubled or tripled to make multiple servings. Cook one at a time unless you have a larger waffle maker.
3. Can I freeze cooked chaffles?
Yes. Cool completely, wrap individually, and freeze. Reheat in a toaster or air fryer for best crispiness.
4. Can I skip the broil step?
Yes, the tuna mixture is ready to eat cold, but broiling melts the cheese and creates a traditional tuna melt effect.
5. Can I use other flours?
Almond flour is best for low-carb purposes. Coconut flour can be used but requires adjustments to moisture (use less flour and more cheese/egg).
