Tuna Melt Recipe with Cheddar and Crispy Toast
A classic tuna melt combines creamy seasoned tuna salad, crisp toasted bread, and warm melted cheddar cheese for a simple lunch that is filling and easy to prepare. This version uses celery and red onion for crunch, while sourdough gives the sandwich a sturdy, golden base that holds the warm filling well.
Why This Tuna Melt Works
The key to a good tuna melt is balancing a creamy filling with crisp, toasted bread and properly melted cheese. The tuna mixture is flavorful without being heavy, and a short cook under a skillet lid helps the cheddar melt before the bread becomes too dark.

Ingredients
For the Tuna Filling
- 2 cans (5 ounces each) tuna in water, drained well
- 1/3 cup mayonnaise
- 1 tablespoon finely chopped celery
- 1 tablespoon finely chopped red onion
- 1 teaspoon Dijon mustard
- 1 teaspoon fresh lemon juice
- 1/4 teaspoon garlic powder
- 1/4 teaspoon black pepper
- 1/8 teaspoon salt, or to taste
For the Sandwiches
- 4 slices sourdough bread
- 2 tablespoons softened butter
- 4 slices cheddar cheese
- 4 small lettuce leaves, optional
- Pickle slices, optional, for serving
How to Make a Tuna Melt
- Prepare the tuna filling. Add the drained tuna, mayonnaise, celery, red onion, Dijon mustard, lemon juice, garlic powder, black pepper, and salt to a bowl. Mix gently until combined. Keep some texture in the tuna rather than turning it into a completely smooth spread.
- Butter the bread. Spread the softened butter evenly over one side of each slice of sourdough. The buttered side will be placed against the skillet to create a crisp, golden crust.
- Build the sandwiches. Place two slices of bread butter-side down. Add one slice of cheddar to each, followed by half of the tuna mixture. Top with another slice of cheddar and the remaining bread, keeping the buttered side facing outward.
- Toast the first side. Heat a large skillet over medium-low heat. Place the sandwiches in the skillet and cook for about 3–4 minutes, until the bottoms are deeply golden and crisp.
- Flip and melt the cheese. Carefully turn the sandwiches over. Cook for another 3–4 minutes. If the bread is browning before the cheese has melted, reduce the heat to low and cover the skillet for 1–2 minutes.
- Serve. Transfer the tuna melts to a cutting board and let them rest for about 1 minute. Cut each sandwich diagonally and serve warm with lettuce and pickle slices if desired.
Tips for a Better Tuna Melt
- Drain the tuna well. Excess liquid can make the filling watery and prevent the sandwich from becoming crisp.
- Use medium-low heat. A tuna melt needs enough time for the cheese to melt without burning the bread.
- Do not overload the sandwich. A moderate layer of tuna keeps the filling from spilling out when the sandwich is flipped or sliced.
- Choose sturdy bread. Sourdough, country bread, or another thick-cut bread works well because it holds the creamy filling without becoming soggy.
- Cover briefly when needed. A lid traps heat and helps the cheddar melt when the bread is already nicely browned.
Variations and Substitutions
For a sharper flavor, replace some or all of the cheddar with Swiss cheese or another good melting cheese. You can add finely chopped dill pickles to the tuna mixture for extra tang, or use a little more Dijon mustard for a stronger savory flavor.
If you prefer a lighter texture, replace part of the mayonnaise with plain Greek yogurt. For extra crunch, add a little more celery or finely chopped pickle. Whole-grain bread can also be used instead of sourdough.
What to Serve with a Tuna Melt
A tuna melt is substantial enough to serve on its own, but it also pairs well with a simple green salad, sliced vegetables, pickles, or a light soup. For a casual lunch, cut the sandwich into halves or quarters and serve it with crunchy vegetables on the side.
Storage and Reheating
The tuna filling can be prepared ahead and stored in a covered container in the refrigerator for up to 3 days. For the best texture, assemble and toast the sandwiches shortly before serving rather than storing fully cooked tuna melts.
If you have a cooked leftover sandwich, reheat it in a skillet over low to medium-low heat until warmed through and crisp again. Avoid microwaving when possible because it can make the bread soft.
