Cheddar Cheese: Go for sharp cheddar slices that melt beautifully under the air fryer’s heat. It adds a creamy, tangy layer that elevates the whole sandwich. In my experience, pre-sliced works best for even melting without extra hassle.

How to Make Air Fryer Low Carb Tuna Melts
Prepare the Tuna Salad Mixture
Start by draining two cans of tuna thoroughly and flaking it into a bowl with a fork. Mix in mayonnaise, diced celery, finely chopped red onion, a squeeze of lemon juice, salt, and pepper for that fresh crunch and zing. This tuna salad is the heart of your Air Fryer Low Carb Tuna Melts, so taste and adjust seasonings to your liking—I’ve found a dash of dill weed adds a herby twist that everyone loves. It only takes about 5 minutes to whip up, setting the stage for assembly.
Assemble the Sandwiches
Now, lay out your low-carb bread slices and spread a generous scoop of the tuna mixture on one side of each pair. Top with cheddar cheese slices, ensuring they cover the tuna evenly for optimal melting. If you like, add a slice of tomato or pickle for extra flavor, but keep it light to maintain the low-carb profile. Press the tops on gently—these stacks are now ready to transform in the air fryer, and the smell alone will have you salivating.
Air Fry to Perfection
Preheat your air fryer to 375°F, then lightly spray the basket with oil to prevent sticking. Place the assembled Air Fryer Low Carb Tuna Melts inside, ensuring they’re not overcrowded for even cooking. Air fry for 5-7 minutes, flipping halfway if needed, until the bread is golden and the cheese is bubbly. Watch closely the first time; in my experience, timing varies by model, but the result is always irresistibly crispy outside with a warm, melty center.

They keep well in the fridge for up to 2 days, though the bread might soften slightly over time. For reheating, pop them back in the air fryer at 350°F for 3-4 minutes to restore crispiness—avoid the microwave to prevent sogginess. Freezing isn’t ideal, but if needed, wrap tightly and thaw before reheating.
Customizing Your Air Fryer Low Carb Tuna Melts

Add jalapeños for heat or olives for Mediterranean flair—experiment to suit your palate. If you’re gluten-free, ensure your low-carb bread fits; for extra protein, mix in chopped hard-boiled eggs.

Timing
Recipe Details
Equipment
Ingredients
- 01 1 (7oz) can tuna packed in water (well drained)
- 02 1 heaping cup shredded cheddar cheese
- 03 1 large egg
- 04 seasoning (but NO salt needed)
Instructions
In a medium size bowl, mix together the drained tuna, cheese and egg until well combined. You can optionally add in some seasoning such as black pepper, garlic powder, and cayenne. I’d avoid salt because the tuna is already loaded with it.
Form the tuna mixture into small, tightly packed patties and place them onto the bottom of your air fryer. I made mine about 2 inches wide.
Air fry at 390°F for 12-16 minutes, flipping them over half way through. After making these a few times, I’ve discovered that they are more done than they look! They continue to crisp up as they cool down.
Allow them to cool for a few minutes and then enjoy alone or with your favorite dipping sauce. I think they're yummy with Ranch dressing!
