A quick and easy lunch recipe featuring creamy tuna, melted cheese, and tangy sourdough bread toasted to golden perfection. Perfect for a comforting and satisfying meal.

Ingredients

Scale
  • 1 can (5 oz / 142 g) canned tuna, drained (preferably albacore)
  • 2 tablespoons mayonnaise
  • 1 teaspoon Dijon mustard
  • 1 stalk celery, finely chopped
  • 2 tablespoons red onion, finely chopped (optional)
  • Salt and freshly ground black pepper to taste
  • 2 thick slices sourdough bread (about 1/2 inch thick)
  • 2 slices sharp cheddar or Swiss cheese
  • 1 tablespoon butter, softened

Instructions

  1. In a medium bowl, combine the drained canned tuna with mayonnaise, Dijon mustard, finely chopped celery, and red onion (if using). Season with salt and pepper to taste. Mix gently until evenly coated but still chunky.
  2. Spread about 1/2 tablespoon of softened butter on one side of each sourdough slice. This will be the outside of the sandwich.
  3. Place one slice of bread, butter-side down, on a clean surface. Spoon the tuna mixture evenly over the bread, spreading close to the edges but leaving a small border.
  4. Lay 2 slices of sharp cheddar or Swiss cheese on top of the tuna mixture.
  5. Cover with the second slice of bread, butter-side up.
  6. Heat a non-stick skillet or cast iron pan over medium heat. Place the sandwich in the pan and press down gently with a spatula.
  7. Cook for 3-4 minutes on the first side until the bread is golden brown and crispy. Flip carefully and cook the other side for another 3-4 minutes.
  8. If the cheese isn’t melting well, lower the heat and cover the pan for 1-2 minutes to trap heat.
  9. Remove the sandwich from the pan and let it rest for a minute.
  10. Slice diagonally and serve immediately while warm and gooey.

Notes

Use medium heat to avoid burning the bread before the cheese melts. Spread softened butter evenly on the bread’s outside for a crispy golden crust. Do not over-mix the tuna filling to keep some chunkiness. Let the sandwich rest for a minute after cooking to help the cheese set. Thick sourdough slices help prevent soggy bread.
