I live for this sharp cheddar tuna melt. It’s so flavorful and crunchy, with a pickle-y tuna salad, melty cheddar and greens. Best lunch ever!

This sandwich is EVERYTHING.

This tuna melt is packed with the most flavorful tuna mixture, melty sharp cheddar cheese, pickled onions, lots of fresh greens and super golden, toasty, buttery crunchy sourdough bread.

UM yes please.

I have never been a huge sandwich person buuuut… I’m kind of turning into a sandwich person.Β 

And it’s all because of this tuna. And lettuce.Β

Sounds weird but hear me out. I’ve never loved sandwiches because I don’t love deli meat. Growing up, my mom always made tuna or chicken salad or something like that. She would make a lot of fried egg sandwiches for us. I loved those! But I never wanted anything with ham or turkey and I couldn’t stand peanut butter and jelly after eating it everyday in my early years.Β 

When I got older and toast became a big thing, I was all about toast. I mean, I’m still all about toast. So, yes, basically an open-faced sandwich. Those I can get behind and even eat one every single day. Give me an array of toppings, a variety of condiments and I am sold.Β

P.S. this tuna melt isn’t THAT different from my tuscan tuna melts. But here we have lots of thick, crunchy sourdough slices and very sharp cheddar. And creamier tuna.Β

So, back to the whole tuna and lettuce thing. This kind of tuna, made with lots of pickles and sweet relish is my love language. I prefer it over any heavy mayo-based tuna salad, for sure. Tuna salad, my egg salad – those are both sandwiches I love to make. I’ll eat this tuna on a sandwich or with crackers. Even with endive cups which are so crisp and refreshing and delicious.

The other thing that has really got me into sandwiches lately is a dressed lettuce situation. Kind of like the lettuce you put on the tiktok famous grinder sandwich. Shredded lettuce, lots of red wine vinegar, a touch of mayo, some seasonings. That, on a sandwich, is an absolute dream! And while it’s not on this particular sandwich, it’s definitely helped my love of sandwiches grow.

Just like my egg salad, I’m picky with my tuna. I want to make it. I will never order it from a deli, ever. There better not be any celery. And it should be briney and tangy but slightly sweet too. I am a very high maintenance tuna person and I accept it.Β

So on to THIS exact sandwich since I’m rambling like a lunatic.

Here’s how you do it!

The tuna. I add in sweet relish, dill relish, dijon and a (very) little bit of mayo.Β 

Sourdough bread is key here. Preferably homemade. Big slices that can get extra crunchy.Β 

The sharpest cheddar you can find. Go for it.Β 

Pickled onions, because I love them on everything. Keep them in your fridge every week!Β 

And some greens, like a handful of arugula or spinach. This adds a bit of crunch even though it will cook down as the sandwich heats.Β

I layer that in between my bread slices. Cook it in a skillet in butter until it is SO golden, SO crispy and crunchy with cheese melting out of the sides.Β 

This is the ultimate tuna melt. One that is so satisfying and decadent. It feels fancy but it’s easy. And it makes lunch feel extra special!Β
