Ingredients :

  • 2 cans (5 ounces each) tuna in water, drained
  • 1/4 cup mayonnaise
  • 1/4 cup celery, finely diced
  • 2 tablespoons red onion, finely minced
  • 1 tablespoon fresh lemon juice
  • 1/2 teaspoon dijon mustard
  • 1/4 teaspoon salt
  • 1/4 teaspoon ground black pepper
  • 4 slices sourdough bread
  • 2 tablespoons unsalted butter, softened
  • 4 slices sharp cheddar cheese
  • 4 slices ripe tomato

Method :

  1. In a medium bowl, combine the drained tuna, mayonnaise, diced celery, minced red onion, lemon juice, and dijon mustard.
  2. Season the tuna mixture with the salt and black pepper, stirring well with a fork to combine and break up any large tuna chunks.
  3. Spread the softened butter evenly on one side of each of the four bread slices.
  4. Place two slices of bread, buttered-side down, on a clean work surface.
  5. Divide the tuna mixture evenly onto the unbuttered sides of the two bread slices on the surface.
  6. Top each portion of tuna salad with two tomato slices and two slices of sharp cheddar cheese.
  7. Place the remaining two bread slices on top of the cheese, with the buttered-side facing up.
  8. Heat a large skillet over medium-low heat.
  9. Place the sandwiches in the skillet and cook for 4 to 5 minutes per side, until the bread is golden brown and the cheese is fully melted.
  10. Remove from the skillet, cut each sandwich in half, and serve immediately.

Recipe Notes :

  • Chef’s Tip: Use high-quality tuna packed in olive oil for a richer flavor and moisture.
  • Variation: Add sliced pickled jalapenos inside the sandwich for a spicy kick.
  • Storage: Store any leftover tuna salad mixture in an airtight container in the refrigerator for up to 3 days; assemble and grill just before serving.

Frequently Asked Questions

What is the best bread for a tuna melt?

Sourdough or sturdy country white bread works best because it toasts beautifully and holds the heavy filling.

Can I use a different type of cheese?

Yes, Swiss, provolone, or Monterey Jack cheese are excellent alternatives to cheddar.

How do I prevent the sandwich from getting soggy?

Make sure to drain the tuna thoroughly and toast the sandwich over medium-low heat so the bread crisps before the cheese melts.
