Ingredients
2 cans (5 oz each) tuna, drained well
1/4 cup mayonnaise
1 tablespoon Dijon mustard (optional)
1/4 cup finely diced celery
2 tablespoons finely diced red onion
1 tablespoon lemon juice
Salt and black pepper, to taste
4 slices bread (sourdough, rye, or whole wheat)
4 slices cheese (cheddar, provolone, Swiss, or American)
Optional toppings: sliced tomato, pickles, fresh parsley
Instructions
Mix the Tuna Salad: In a bowl, combine tuna, mayonnaise, mustard (if using), celery, red onion, lemon juice, salt, and pepper. Mix until creamy and evenly combined.
Assemble: Lay bread slices on a clean surface. Spoon tuna mixture evenly over each slice. Top with a slice of cheese.
Air Fry: Place sandwiches in the air fryer basket in a single layer. Air fry at 375°F (190°C) for 6–8 minutes, until the bread is crisp and the cheese is melted and bubbly.
Serve: Carefully remove, add optional toppings, and serve hot.
Notes
Cooking Tips
-
Drain tuna thoroughly to prevent soggy bread.
-
Open-faced works best for even melting and crisp edges.
-
Check at 5 minutes—air fryers vary, and cheese can melt fast.
-
For extra crunch, lightly butter or spray the bread edges before air frying.
Variations
-
Healthy Swap: Use Greek yogurt instead of mayo and whole-grain bread.
-
Spicy Tuna Melt: Add diced jalapeños or a dash of hot sauce.
-
Mediterranean Style: Mix in capers, olives, and use provolone or mozzarella.
-
Low-Carb: Skip the bread and air fry the tuna mixture in portobello mushroom caps or on bell pepper halves.
