To take a tuna melt from good to great, it has to have all the right components. In other words, plain mayo alone won't cut it. Here's how we do it: open-faced with crusty toasted bread, melty cheese, capers, cornichons, Dijon mustard, and plenty of seasoning. On a chilly fall day, nothing tastes better.

Ingredient Checklist


Instructions Checklist
  • Set the oven to broil and move the rack to the highest position.

  • In a medium bowl, combine tuna, mayonnaise, mustard, red onion, capers, cornichons, lemon juice, thyme, salt, and pepper and stir thoroughly until combined. Leave the tuna in slightly large chunks, if possible.

  • Arrange bread on a baking sheet and spread mayonnaise on each slice. Divide tuna salad evenly among slices, then top each with 2 slices of tomato and 1 slice of cheese.

  • Broil tuna melts until cheese is golden brown and bubbling, 3 to 4 minutes. Serve warm.

great base recipe. grilled one side of the bread first so that it was nice and crispy. changed around the spices a bit (added smoked paprika) used solid white albacore subbed in shallots and green onions used a nice olive bread added avocado after broiling. IMHO a nice cheddar is a key ingredient to a tuna melt so use that if you have it on hand. Read More

I use pickle relish which made it sweeter than it should have been. Other wise it was a good recipe Read More

I loved this idea! The thyme and red onions are great! I am obsessed with marinated artichoke hearts right now so I had those and not the capers. It still added the pickled flavor. I ve made a version of this sandwich 4 times in a week. Sharp cheddar on top. Broiled. Yummy. Read More
