Please share

Classic tuna melts are quick and easy to make, and they are so good. The open faced sandwich has tuna salad, melted cheese, and tomato for the best mix of warm and cozy with fresh and tasty.

Whether you are looking for a quick and easy lunch or an option for Lent, these tasty tuna melt sandwiches are just the thing. It’s time to bring back the tuna melt!

This is one of those vintage recipes that scream diner classic to me. I can just imagine folks going out for dinner in the 1960s and ordering one.

Tuna melts topped with tomato, ready to eat.

They were brand new and supposedly discovered by accident when a bowl of tuna salad spilled onto a grilled cheese. Whether that is true or not, who knows. But, it is a fun story!

Either way, I am sure the housewives of the era were happy to have a new trendy meal to make that was simple to put together. I’ll have to ask my grandma what she thought when they came onto the scene.

No matter the history, Little Dude was introduced to his first tuna melt when we were testing tuna melt recipes. He didn’t think he liked tuna going into it, but he is a fan now!

We have been on a run of tuna melts, and this recipe is our favorite. We hope you give it a try for yourself!

What You’ll Need

This is one of those really simple recipes that can easily be customized to what you have on hand, and it will still be delicious.

However, a few tips can make them extra fabulous. So here are some recommendations after our testing:

Ingredients including bread, tuna, mayonnaise, mustard, pickle relish, onion, celery, cheese, and eggs ready to be made into tuna melt sandwiches.

Tuna – Your favorite canned tuna will work great. You can use oil packed for more flavor, but water packed works well, too. Starting with a drained canned of tuna keeps the recipe super simple and really affordable.

Bread – Lightly toasted sandwich bread will work fine, so go ahead and use it if that is what you have.

However, something a little bit hearty is great too. We tried some on my mom’s homemade sandwich bread, and it was fabulous.

Nice thin slices of sourdough bread are wonderful, too. They taste great, have a nice sturdy texture, and allow for a slightly bigger portion.

Cheese – We like using a nice shredded cheddar on our tuna melts. It is a classic pairing.

However, Swiss or gouda are great options as well. You can use a slice of cheese if you want, or go ahead and grate it so it can cover edge to edge.

Tomatoes – The tomato is optional but highly encouraged. We like to put a slice of cold or room temperature tomato on top of the hot sandwich.

However, if you prefer your tomato warm, just put it on the sandwich under the cheese. Both ways are good, so it is just a matter of preference.

The rest – everything else is just standard tuna salad fare. We use celery, pickle relish, mayonnaise, and Dijon mustard.

Sometimes, we toss in chopped hard-boiled eggs as well. It just depends on our mood.

If you want to fancify it a bit, add a little fresh dill for garnish. It tastes great with the tuna and adds a little bit of frill.

Frequently Asked Questions

Can I make tuna melts in advance?

The tuna salad can be made up to 3 days in advance. Then all you have to do is assemble the sandwich and you are ready to go.

The tuna melts themselves are best fresh. However, if you make too many, you can wrap them in plastic wrap or put them in an airtight container and enjoy it as a tuna sandwich later.

Just know that the bread will likely get a bit soggy as it sits.

What toppings can I put on my tuna melt?

If you want even more than melty cheese and a slice of tomato, don’t despair. Try adding sliced avocado, some lettuce, or your favorite deli pickles.

Do you have to eat tuna melts open face?

Of course not! Our preference is to eat them open faced. We usually eat them with a fork, but sometimes, we will pick them up and eat it as is.

However, you can toast a second piece of bread and put it on top after you cheese is melted. Then you can pick it up and eat it like a sandwich.

This recipe will make 4 melts using sandwich bread sized slices. Or it will make 2-3 larger
sandwiches if you use a bigger loaf of sourdough or rye bread.
We like the contrast of the warm sandwich and the cold tomato. However, you can put the tomato under the cheese and cook it along with the sandwich if you prefer it to all be warm.
You can make the tuna salad up to 3 days in advance. Just store it in an airtight container in the refrigerator until you are ready to assemble your melts.
Both sweet and dill pickle relish taste great in tuna salad. Pick whichever you prefer or are in the mood for.

Always been a fan of tuna melts. I make them in English muffins but I’m going to try like this. Looks so good.

I love a good tuna melt! Never heard of that "accident" origin story, but it makes sense! Don't always think of putting tomato on a tuna melt, but what a great idea!

The tomato gives it a nice pop of cool acidity with goes so nicely with the warm, creamy tuna and cheese.
