Cheesy Tuna Melt Cakes have a crunchy exterior that leads to soft potato, corn and tuna cake with a warm melted cheese center.

I am a huge fan of good salmon cakes. But instead of making salmon cakes, I wanted to do something a little different.

These cheesy tuna melt cakes were inspired by my husbands favorite sandwich, the tuna melt. But instead of the cheese being on the outside, the cheese is stuffed into the cakes for a melty cheesy center.

What cheese is best?

A good white, melting cheese is best. One that will stand up to the flavor of the tuna.  I like havarti, white cheddar, gruyere, provolone.

How to make the Cheesy Tuna Melt Cakes

The cakes start with mashed potatoes. They are mixed with a good quality, sustainable canned tuna. The zest and juice of a lemon are added for delicious freshness along with yellow mustard, a good quality mayonnaise, corn for sweetness and fresh chopped chives for just a hint of onion flavor.

Now, here comes the best part, the cheese filling. Form the cakes into a flat round, add a cube of cheese and push it into the center. Re-form the patties so the cheese is well covered into 3 inch diameter by 1 inch high cakes. Refrigerate for 30 minutes to set their shape.

The cakes are coated egg and  panko breadcrumbs, which is the best choice because we want them as crispy as possible. They are then shallow fried to a perfect golden brown.

You might say these are similar to tuna croquettes, just gussied up with potato, corn and melted cheese.

The cakes are garnished with a very easy lemon mayonnaise; made simply with fresh lemon juice and mayonnaise mixed together that is a fresh tasting ‘sauce’ which complements the cakes perfectly.
