Ingredients You’ll Need

For the Tuna Filling:

• 1 tablespoon mustard (optional)
• 1 celery stalk (finely chopped)
• 2 tablespoons onion (finely chopped)

For the Sandwich:

Step-by-Step: How to Make the Best Tuna Melt

Step 1: Prepare the Tuna Mixture

In a bowl, combine tuna, mayonnaise, mustard, celery, onion, lemon juice, salt, and pepper. Mix until creamy but still slightly chunky.

Step 2: Assemble the Sandwich

Spread the tuna mixture evenly on one slice of bread. Add cheese on top, then place another slice of bread to close the sandwich.

Step 3: Butter the Bread

Spread butter on the outside of both slices. This helps achieve that golden, crispy texture when grilled.

Step 4: Cook Until Crispy

Heat a pan over medium heat. Place the sandwich in the pan and cook for about 3 to 4 minutes per side until the bread is golden brown and the cheese is fully melted.

Step 5: Serve Warm

Remove from heat, slice in half, and serve immediately while the cheese is gooey and delicious.

Tips for the Perfect Tuna Melt

The secret to a great tuna melt is all about balance.

Don’t overload the tuna mixture or the sandwich can become soggy
Use medium heat so the bread crisps without burning
Choose a cheese that melts well for that creamy texture
Toast slowly to allow the cheese to melt evenly

These small steps make a big difference in the final result.
