Easy Tuna Melt Sandwich Recipe
What Is a Tuna Melt Sandwich?
A Tuna Melt Sandwich is a warm sandwich made with creamy tuna filling, melted American cheese, and buttery toasted bread. It’s like a mix of a grilled cheese sandwich and tuna salad. It’s warm, cheesy, and full of flavor—perfect for lunch or dinner.
Ingredients (for 4 sandwiches)
- 4 (5-ounce) cans of drained tuna
- 2/3 cup mayonnaise
- 2 small ribs of celery, diced
- 1 clove garlic, finely minced
- 1 tablespoon capers, finely minced
- 1 small dill pickle, diced (about ¼ to ⅓ cup)
- ½ of a medium red onion, peeled and diced (about ½ cup)
- 1 tablespoon fresh dill, finely chopped
- Juice of ½ lemon (about 1½ tablespoons)
- 4 tablespoons unsalted butter
- 8 slices of white bread
- 8 slices of American or cheddar cheese
- Salt and black pepper to taste
Instructions
- Make Tuna Mixture
In a large bowl, mix together tuna, mayonnaise, celery, garlic, capers, pickle, onion, dill, lemon juice, salt, and pepper until well combined. - Toast the Bread (First Side)
Heat 1 tablespoon of butter in a skillet or griddle over low-medium heat. Once melted and bubbling, place 4 slices of bread in the pan and toast for 2 minutes. - Flip and Add Cheese and Tuna
Flip the bread over. Add another tablespoon of butter to the pan. Place 1 slice of cheese on each toasted bread slice. Spread some of the tuna mixture on two of the slices. - Close the Sandwich & Cook
Put the other slice of bread (with just cheese) on top of the tuna-covered slice, with the cheese facing down. Cook for 2 minutes until the sandwich is golden brown and cheese is melty. - Slice & Serve
Remove the sandwiches from the pan, let them rest for a moment, then slice in half. - Repeat
Repeat with remaining butter, bread, cheese, and tuna filling to make two more sandwiches.
Tips & Tricks
- Don’t make it soggy: Make sure the tuna is well drained. Too much mayo or wet tuna will make the bread soggy.
- Low-medium heat is best: Cooking on low-medium helps get crispy golden bread without burning.
- Try open-faced: Place tuna and cheese on one slice of toasted bread and broil for 2–3 minutes until cheese bubbles.
- Flavor it your way: Add things like paprika, green onions, hot sauce, horseradish, or roasted red peppers to change the taste.
- Add toppings: Make it more filling with sliced tomato, bacon, or extra pickles before adding the top slice.
Serving Suggestions
- Great with fries, potato chips, or a pickle spear
- Add coleslaw or potato salad for a classic deli-style lunch
- Perfect with a warm bowl of tomato soup for a cozy meal
Make-Ahead & Storage
- Make-Ahead: Make the tuna mix a day in advance and store it in the fridge in a sealed container. Assemble and cook the sandwiches when ready to eat.
- Storing Leftovers: Store leftover sandwiches or filling in the fridge for up to 2 days.
- Reheating: Warm in a skillet on low heat, or use a 375ºF air fryer or toaster oven until hot and crispy.
