I’ve been making tuna melts since I was a teenager, and honestly, they never get old. There’s something so satisfying about that combination of creamy tuna salad and melted cheese on toasted bread. The key is getting everything just right – not too much mayo in the tuna, the perfect amount of cheese, and timing that broiler so the top gets golden without burning.
My version uses a mix of canned tuna (I prefer the kind packed in water) with just enough mayonnaise to bind it together. I add diced celery for crunch and a squeeze of fresh lemon juice to brighten everything up. Some people go heavy on the mayo, but I think that makes the whole thing soggy. You want the tuna mixture to hold together but not be swimming in dressing.
Getting the Tuna Salad Right
The cheese situation is crucial here. I use a good sharp cheddar or Swiss – something that melts well but has enough flavor to stand up to the tuna. And here’s my secret: I toast the bread first, then add the tuna, then the cheese. This prevents the bottom from getting soggy while the top is browning under the broiler. The whole thing takes maybe ten minutes from start to finish.
Why Toasting First Makes All the Difference
These are perfect for a quick lunch or light dinner. I often serve them with some pickles and maybe a simple green salad. They’re also great for using up that extra loaf of challah or rye bread that’s starting to get a little stale.

Ingredients
Method
- Preheat your broiler and position the oven rack about 6 inches from the heat source.
- In a medium bowl, combine the drained tuna, mayonnaise, diced celery, lemon juice, salt, and pepper. Mix gently with a fork, breaking up the tuna but not mashing it completely.
- Toast the bread slices in a toaster or toaster oven until lightly golden. You want them crispy but not too dark since they're going back under the broiler.
- Arrange the toasted bread on a baking sheet. Divide the tuna mixture evenly among the 8 slices, spreading it to the edges.
- Top each slice with cheese, covering the tuna mixture completely. The cheese should go right to the edges to prevent the tuna from drying out.
- Broil for 2-3 minutes, watching carefully, until the cheese is melted and golden brown in spots. The timing depends on your broiler, so keep an eye on them.
- Remove from oven and let cool for a minute before serving. The cheese will be very hot.
