Grilled Tuna Melt

Tuna melt sandwiches are one of the forgotten grilled sandwiches because when it comes to grilled cheese because we don’t see it on menus as often as they should be. Creamy, cheesy with fantastic flavor, grilled tuna melts truly melt in your mouth. They are a fantastic lunch sandwich and when paired with a crisp cool salad, it’s an awesome lunch. It’s a great way to use leftover tuna salad and sometimes we eat it up so quick, we have to make a whole new batch just for the tuna melt sandwiches!

Tips on Making Grilled Tuna Melt

We’ve found one of the key variables in making a tuna melt sandwich is the relationship between browning the bread and melting the cheese. Too high of heat and the bread is golden but the cheese hasn’t melted. Too low and it will eventually become a decent tuna melt sandwich, but it takes forever. So find a nice melting cheese to use and don’t cook it too hot. Especially if your bread has a bit of sugar in the ingredient. Those breads are more sensitive to cooking will often brown quicker than other slices of bread. Hope that helps and Enjoy!

Gooey, Cheesy Tuna Melt

Canned tuna fish varies in texture. Some are chunkier and some are more mushy so add the amount of mayo to your preferred taste. Some folks like their tuna extra creamy and some like it drier, with less. So add accordingly!
Different breads will brown quicker than others. If the heat it too warm, the bread may brown quicker than the cheese can melt, so if the bread is very soft or has any sugar in the dough (check the bread ingredients) cook on a little lower heat to make sure the cheese gets to melt by the time the bread browns. It will take a little longer but you’ll get an even browning to cheese melt ratio.
