Preparation Guide
Ingredients

• 1 cup canned tuna, drained (approx. 165 g)
• 1/2 cup shredded cheese (cheddar or mozzarella), packed (~56 g)
• 2 large eggs
• 1/4 cup almond flour (~28 g)
• 1/4 cup mayonnaise (~60 g)
• Salt and pepper to taste (start with 1/4 tsp each)
• Cooking spray or oil for the chaffle maker

Optional ingredients and substitutions

• Swap mayonnaise with plain Greek yogurt (for lower fat) or avocado mayo for a cleaner-fat profile.
• Use tuna in water or oil depending on preference — tuna in water reduces calories and fat.
• Add 1–2 tablespoons chopped green onion or dill for freshness.
• Substitute 1/2 cup cottage cheese blended smooth for mayo (adds protein).
• For dairy-free: use a dairy-free shredded cheese alternative (results may vary).

Method & Process

1. Preheat your chaffle maker according to the manufacturer’s instructions.
2. In a medium bowl, flake and drain the canned tuna, then add the shredded cheese, eggs, almond flour, mayonnaise, salt, and pepper. Mix until well combined — avoid overmixing to preserve some texture.
3. Grease the chaffle maker lightly with cooking spray or brush with oil.
4. Spoon the tuna mixture into the chaffle maker (use about 1/2 of the mixture per chaffle if your maker makes two), close it, and cook for 3–5 minutes, or until the chaffles are golden brown and set.
5. Carefully remove the chaffles and serve warm. Optionally top with extra cheese or herbs.

Practical tips

• Do a test chaffle first to check cooking time: different machines vary in heat. If the center seems soft after 5 minutes, add 30–60 second increments.
• Avoid excess moisture: drain tuna well and pat dry to prevent soggy chaffles.
• For extra crispness, finish chaffles in a toaster oven or air fryer at 375°F (190°C) for 2–3 minutes.
• If using tuna in oil and you want less fat, drain and blot well or reduce mayonnaise.

Serving Suggestions
Best Pairings

• Classic: Serve the chaffles plain or with a light spread of butter for breakfast with a cup of coffee or tea.
• Melted & Topped: Add a slice of tomato and broil briefly to melt extra cheese on top; finish with fresh parsley.
• Dipping: Offer lemon-garlic aioli, spicy sriracha mayo, or a scoop of Greek yogurt mixed with dill.
• Sandwich-style: Use two chaffles as “bread” with extra tuna salad, pickles, and leafy greens for a handheld lunch.
• Lighter sides: Pair with a simple mixed greens salad, cucumber ribbons, or roasted asparagus.

Shelf Life & Storage

• Room temperature: Do not leave chaffles out at room temperature for more than 2 hours (per food safety guidelines).
• Refrigeration: Store in an airtight container for up to 3–4 days. Reheat in a toaster oven, oven, or air fryer to restore crispness.
• Freezer: Wrap individually in parchment and place in a freezer bag for up to 2 months. Reheat from frozen in an air fryer at 350°F (175°C) for 6–10 minutes, flipping halfway, until heated through.

Chef’s Advice

• Cheese choice matters: Cheddar gives robust flavor and an excellent crisp; mozzarella produces more stretch and milder flavor. A blend can be ideal.
• Texture balance: Almond flour provides structure and a slightly nutty crumb — don’t swap it 1:1 with coconut flour (it absorbs more liquid).
• Tuna type: Tuna in water keeps fat lower; tuna in oil increases richness. Taste and adjust salt since some canned tuna is already salted.
• Doneness cues: Look for golden-brown edges and a firm center. If it jiggles, give it a bit longer.
• For extra binding, an extra egg white can help if your mixture seems loose; conversely, add a tablespoon more almond flour if excessively wet.

Creative Twists

• Mediterranean Tuna Chaffles: Mix in chopped kalamata olives, sun-dried tomatoes, crumbled feta, and a pinch of oregano. Top with fresh arugula and a squeeze of lemon.
• Spicy Sriracha Twist: Stir in 1–2 teaspoons sriracha or chili paste to the tuna mixture and top with sliced jalapeños for heat.
• Tuna Avocado Open Chaffle: Top each chaffle with smashed avocado, a scoop of tuna, and microgreens for a brighter, fresher bite.
• Lower-Fat Version: Replace mayonnaise with 3 tablespoons Greek yogurt and 1 teaspoon olive oil; reduce cheese to 1/3 cup and choose a lower-fat cheese.
• Extra-Crisp Air-Fryer Finish: After cooking in the chaffle maker, pop chaffles into a preheated air fryer (350°F / 175°C) for 2–3 minutes for maximum crunch.

All Your Questions Answered
Q: Can I make these without almond flour?
A: Almond flour provides structure and a low-carb profile. You can try 1/4 cup coconut flour, but you’ll need less (about 2–3 tbsp) and may need extra liquid — results will change.

Q: How do I prevent a soggy center?
A: Drain the tuna thoroughly and pat dry, limit wet add-ins, and ensure your chaffle maker is fully preheated. Finish in a toaster oven or air fryer if needed.

Q: Are these suitable for a keto diet?
A: Yes — this recipe is low in carbs and high in fat/protein, fitting well into many ketogenic meal plans. Check specific macros to match your daily goals.

Q: Can I prepare the mix ahead of time?
A: You can mix and refrigerate the filling for up to 24 hours, but cook chaffles just before serving for best texture.

Q: What’s a healthier mayo alternative?
A: Plain Greek yogurt or mashed avocado both reduce fat and add nutrients while changing the flavor profile slightly.
