About Tuna Melt
The tuna melt is an American diner and lunch-counter fixture — tuna salad and melted cheese pressed between bread and griddled until crisp. It sits at the crossroads of the tuna sandwich and the grilled cheese, taking the creamy, celery-flecked tuna filling and warming it under a blanket of melting cheddar so the whole thing turns rich and gooey. This version uses baguette and Kewpie mayonnaise, the Japanese mayo whose egg-yolk richness and gentle tang give the tuna salad more depth than the standard supermarket jar.
What you want from a tuna melt is contrast: a shatteringly crisp, butter-golden exterior giving way to warm, creamy tuna and stretchy melted cheese, with the diced celery adding a small fresh crunch against all that richness. Buttering the outside of the bread and cooking it low and patient in a skillet is the technique that gets both a proper crust and fully melted cheese without scorching. It is high in protein and comes together in about fifteen minutes, which makes it a legitimately good quick lunch or dinner. Serve it hot and cut on the diagonal, ideally with something sharp on the side — pickles or a simple salad — to balance the density.
