There’s just something about a tuna melt that hits all the right notes—crispy, creamy, gooey, and comforting in every bite. It’s that nostalgic diner classic that somehow always feels like the perfect lunch, especially when served hot off the skillet with a side of chips and an iced tea.

If you’ve only had tuna melts at your local lunch spot, it’s time to bring that magic home. This sandwich is surprisingly easy to make with pantry staples, and you can customize it with your favorite cheese, bread, or even swap the tuna if you’re in the mood. It’s a simple, satisfying recipe that’s great for busy weekdays or lazy weekend lunches.
Ingredients You’ll Need
- 2 cans tuna (well-drained; I like using sustainably sourced)
- ⅓ cup mayonnaise (or Greek yogurt, if preferred)
- 1 rib celery, finely chopped
- 2 tablespoons pickle relish (or chopped dill pickles)
- 2 tablespoons red onion, finely chopped
- Salt and pepper, to taste
- 8 slices sandwich bread (rustic bread like sourdough works best)
- 4 slices ripe tomato (optional, but delicious)
- 4 slices cheddar cheese (or use Swiss, provolone, or pepper jack)
- Butter, for the bread (or mayo if you prefer to spread that)

How to Make a Tuna Melt
Make the Tuna Salad
In a mixing bowl, combine the drained tuna with mayo, celery, relish, and red onion. Season with salt and pepper to taste. Stir until everything’s well combined. You can make this a day ahead and keep it chilled until ready to use.
Build the Sandwiches
Butter one side of each bread slice. On the unbuttered side of half the slices, layer a scoop of tuna salad, sliced tomato (if using), and a slice of cheese. Top with the remaining bread slices, buttered side facing out.
Cook to Melty Perfection
Heat a skillet or griddle over medium heat. Place sandwiches in the pan and cook until golden brown on the bottom. Flip carefully and cook until the second side is golden and the cheese is melted. Each side should take about 3–4 minutes.
Serve Hot
Slice the sandwiches in half and serve immediately. These are perfect with potato chips, pickled veggies, or a side salad.
Tips for the Best Tuna Melt
- Don’t skimp on the bread – Use sturdy bread that holds up to the heat and filling. Rustic sourdough or whole wheat works better than soft white bread.
- Add crunch – Celery and onion are classic, but finely chopped apples work great if you want a touch of sweetness.
- Get that golden crust – Buttering the outside of the bread (or spreading on mayo) gives you that perfectly crisp texture.
- Mix up your cheese – Try provolone, Swiss, or pepper jack for different flavor vibes.
- Toast it right – A nonstick skillet or cast iron pan gives great browning. Press slightly with a spatula to help melt the cheese.

FAQs
Can I make it ahead?
Yes, the tuna salad can be made up to 3 days ahead and stored in the fridge. Assemble and cook the sandwich just before serving for the best texture.
Can I make it open-faced?
Absolutely! Toast one slice of bread, add tuna salad and cheese, then broil until melty.
Can I use something other than tuna?
Try cooked shredded chicken or flaked salmon as a delicious twist.
What’s the best cheese to use?
Cheddar is a classic, but provolone, Swiss, colby, or mozzarella are all melty favorites.
Final Thoughts
The next time you’re craving something comforting, skip the deli line and whip up this easy tuna melt sandwich at home. With its golden crust and warm, cheesy center, it’s a classic you’ll come back to again and again.
