Filled with delicious tuna salad, a layer of cheddar, and fresh sliced tomato this Tuna Melt is baked to perfection in the oven until the cheese is perfectly melted and the bread is crispy golden brown. It’s the ultimate hot sandwich that makes a fantastic easy lunch or dinner!
In a medium size bowl add the tuna, mayonnaise, lemon juice, celery, green onion, fresh parsley, salt, pepper and mix until well combined.
Spread butter on one side of each bread slice. Place 4 slices on a baking sheet, with the buttered side down.
Top each slice of bread with ¼ of the tuna salad, 2 slices of the cheddar cheese and tomato slices. Top with the other slices of bread with the buttered side up.
Transfer the baking sheet to the oven and bake until the cheesy melts, 5 to 8 minutes.
Use tuna in water. Use tuna in water and drain it well. The tuna in oil is not only less healthy but will be way too oily when mixed with the mayo.
Taste for salt. After you mix all the tuna salad ingredients together, taste for salt and add more if needed. You always want to wait till the very end to add any additional salt.
Fully butter the bread. Make sure the butter is softened and that you evenly spread it all over the slices of bread so that the tuna melt bakes to a crispy golden brown.
Already cooked tuna melts will keep in the fridge for up to 3 days. However, they don’t tend to freeze well. To reheat, put the sandwiches in the oven at 350°F (177°C) on a sheet pan for about 10 minutes.
