Recipe Information
Prep Time: 10 minutes
Cook Time: 8 minutes
Total Time: 18 minutes
Servings: 2
Ingredients
2 cans tuna, drained well
¼ cup mayonnaise
1 tablespoon Dijon mustard
2 tablespoons finely chopped celery
2 tablespoons finely chopped red onion
1 teaspoon lemon juice
¼ teaspoon black pepper
¼ teaspoon garlic powder
4 slices bread
1 cup shredded cheddar cheese
2 tablespoons butter, softened
Chopped parsley, optional
How to Make the Tuna Filling
Add the drained tuna to a medium bowl. Break it apart with a fork until it is flaky.
Add the mayonnaise, Dijon mustard, chopped celery, chopped red onion, lemon juice, black pepper, and garlic powder. Mix until the tuna is creamy and evenly seasoned.
Taste the filling and adjust the seasoning if needed. You can add a little more mayonnaise for a creamier texture or more lemon juice for a brighter flavor.
How to Make a Cheesy Tuna Melt
Spread a thin layer of softened butter on one side of each slice of bread.
Place two bread slices butter-side down on a clean surface. Add a layer of shredded cheddar cheese to each slice.
Spoon the tuna mixture evenly over the cheese. Add the remaining cheddar cheese on top of the tuna filling, then place the second slices of bread on top with the buttered sides facing outward.
Heat a skillet over medium-low heat. Place the sandwiches in the skillet and cook for 3 to 4 minutes per side.
Press the sandwiches gently with a spatula as they cook. The bread should become golden and crisp, while the cheese melts fully inside.
Remove the sandwiches from the skillet and let them rest for one minute before slicing. This helps the filling stay inside and gives the cheese time to settle slightly.
Tips for the Best Tuna Melt
Drain the tuna very well before mixing it with the other ingredients. Excess liquid can make the filling watery and cause the bread to become soggy.
Cook the sandwiches over medium-low heat rather than high heat. Lower heat allows the cheese to melt before the bread gets too dark.
Use a sturdy bread that can hold the creamy filling. Sourdough, white sandwich bread, whole wheat bread, or thick-cut bakery bread all work well.
For an extra cheesy melt, use a blend of cheddar and mozzarella.
Easy Variations
Add sliced tomato inside the sandwich for a fresh classic tuna melt. Pat the tomato dry first so the sandwich does not become too wet.
For a spicy version, mix a little hot sauce, diced jalapeño, or crushed red pepper flakes into the tuna filling.
Add chopped pickles or relish for a tangy flavor. You can also use Swiss cheese, provolone, pepper jack, or American cheese instead of cheddar.
For a lighter option, use Greek yogurt in place of part of the mayonnaise.
What to Serve with a Tuna Melt
Serve your tuna melt with potato chips, French fries, sweet potato fries, a green salad, tomato soup, or coleslaw.
A bowl of pickles, sliced tomatoes, or fresh fruit also makes a simple and delicious side.
Storage and Reheating
The tuna filling can be stored in an airtight container in the refrigerator for up to two days.
For best texture, cook the sandwiches fresh when you are ready to eat. If you have leftover cooked sandwiches, reheat them in a skillet or air fryer until warm and crisp.
Avoid reheating in the microwave for too long because the bread can become soft.
Common Mistakes to Avoid
Do not cook the sandwich over high heat. The bread can burn before the cheese melts.
Avoid using too much tuna filling. A thick layer can make the sandwich difficult to flip and may spill out while cooking.
Do not skip buttering the outside of the bread. It gives the sandwich its golden, crisp grilled-cheese texture.
