Air Fryer Tuna Melt

Equipment

• Air fryer (any size; a 4–6 quart model works best)
• Mixing bowl
• Fork
• Butter knife or spatula
• Toothpicks (optional, for securing sandwiches)

Ingredients

For the Tuna Salad

• 1 can (5 oz / 142 g) solid white tuna in water, drained well
• 3 tablespoons mayonnaise
• 1 teaspoon Dijon mustard
• 1 stalk celery, finely diced
• 2 tablespoons red onion, finely diced (optional)
• 1 tablespoon sweet pickle relish (optional but recommended)
• 1 teaspoon fresh lemon juice
• ¼ teaspoon garlic powder
• ¼ teaspoon onion powder
• Salt and black pepper, to taste
• 1 tablespoon fresh parsley, chopped (for garnish)

For the Sandwiches

• 4 slices sourdough, Italian, or rye bread (or 2 thick slices cut in half)
• 2 tablespoons unsalted butter, softened
• 4 slices cheddar, Swiss, or mozzarella cheese (about 4 oz / 113 g total)
• Optional: sliced tomato, avocado, or extra pickles for serving

Instructions

Step 1: Prepare the Tuna Salad (5 minutes | Intensity: Easy)

1. In a medium mixing bowl, combine the drained tuna, mayonnaise, Dijon mustard, diced celery, red onion, relish, lemon juice, garlic powder, and onion powder. Use a fork to flake the tuna and mix everything together until well combined but still slightly chunky. Season with salt and pepper to taste. Set aside.
2. Tip: Drain the tuna thoroughly. Excess moisture can make the bread soggy in the air fryer.

Step 2: Assemble the Sandwiches (3 minutes | Intensity: Easy)

1. Lay the four slices of bread flat on a clean surface. Butter one side of each slice generously — this will be the outside of the sandwich, helping it crisp up beautifully.
2. Flip two slices over so the buttered side faces down. Divide the tuna salad evenly between them, spreading it to the edges. Top each with two slices of cheese, then place the remaining bread slices on top, buttered side up.
3. If your sandwiches feel tall or unstable, secure them with a toothpick through each corner.

Step 3: Preheat the Air Fryer (2 minutes | Intensity: Easy)

1. Set your air fryer to 370°F (188°C) and let it preheat for 2 minutes. Preheating is essential for even crisping — don’t skip this step.

Step 4: Air Fry the Sandwiches (8–10 minutes | Intensity: Easy)

1. Carefully place the sandwiches into the air fryer basket. If your air fryer is small, cook them one at a time to avoid overcrowding. Cook at 370°F (188°C) for 8–10 minutes , flipping halfway through at the 4–5 minute mark.
2. Timing Guide by Texture:
3. 6–7 minutes: Soft, lightly toasted bread and just-melted cheese
4. 8–9 minutes: Golden, crispy exterior with fully melted cheese (recommended)
5. 10–12 minutes: Deep golden, extra crunchy, cheese slightly browned at edges
6. Keep an eye on them during the final minutes, as air fryers vary in intensity and heat distribution.

Step 5: Rest and Serve (1 minute | Intensity: Easy)

1. Remove the sandwiches from the air fryer and let them rest for 1 minute. This allows the cheese to set slightly so it doesn’t run everywhere on the first bite. Remove toothpicks if used, slice in half diagonally, and garnish with fresh parsley.
2. Serve immediately with extra pickles, a handful of chips, or a simple side salad.
