Canned tuna helped get me through college, and I still have a soft spot for it even as an adult. I love me a classic tuna melt, and if you do too, this budget-friendly recipe definitely has your name on it. There’s something nostalgic about a diner-style tuna melt that’s slathered in butter and then crisped to perfection. The crunchy toast hugs the creamy, savory tuna salad filling, sandwiched between the warm, gooey richness of melted cheddar cheese. It’s essentially a grilled cheese taken to the next level.

Easy classic tuna melt Recipe
Tuna melts are one of those sandwiches I never get bored of making. There are endless ways to jazz them up—adding capers, lemon, fresh herbs, yogurt, mustard, hot sauce, or crunchy veggies like cucumber or peppers. Between switching up the bread and cheese and layering in extras like avocado, tomato, or bacon, I almost never end up with the same sandwich twice.
I like to keep my tuna melt simple, and combine the tuna with my favorite pickles, sharp red onions, crunchy fresh celery, and creamy mayo. Whether you’re reliving dorm room dinners or just craving something cozy, this tuna melt hits the spot every single time!
Recipe Success Tips
- Work in batches if needed. My skillet could only fit two sandwiches at a time, so I had to work in batches. Feel free to cook all the sandwiches at the same time if your skillet can accommodate them.
- Drain the tuna really well. This ensures there is no excess water to dilute the flavor.
- Watch the pan carefully. Be careful with the butter as it burns easily. Don’t take your eyes off the pan for too long or the bread will burn. I love getting the bread nice and crispy so the cheese melts into the tuna, and I get a delicious creamy burst of flavor and texture with each bite.
- Thin cheese slices. Pre-sliced cheddar cheese is nice and thin, but if you cut your own, make sure the slices aren’t too thick, or they won’t fully melt.
- Use a sturdy bread. You want to make sure it can hold all the goodies we are putting in this sandwich.

serving suggestions
When I serve a tuna melt, I like to round it out with sides that balance all that cheesy, buttery goodness. Crispy chips are a must, especially when paired with fresh veggies dipped in homemade hummus for a little crunch and freshness. If I’m in the mood for something cozy, a bowl of butternut squash soup makes the perfect comforting companion. And on nights when I want to lean fully into comfort food, air fryer french fries are always a winning choice.
Storage and Reheating
If you don’t want to make all 4 sandwiches at the same time, the tuna salad can be stored in an airtight container in the refrigerator for 3-4 days.
If you’ve prepared the sandwiches and toasted them, but there are leftovers, wrap them up tightly and store them in the fridge for 3-4 days. Reheat by popping them in the toaster until the cheese melts and the bread crisps up again.
