If you’re already a fan of my Classic Tuna Salad recipe, you’re going to love this next-level comfort food: the Tuna Melt. It’s everything you love about tuna salad—creamy, tangy, and satisfying—but sandwiched between golden, crispy bread and melty cheese (or served open faced!).

This is a totally easy and inexpensive lunch or dinner. The nice thing is you can make the tuna salad ahead to it is ready when you are.

Ingredients Details

  • Tuna – buy cans of high quality canned chunk white albacore tuna for the best results.
  • Mayonnaise – The base for a creamy tuna salad.
  • Celery and Red Onion– Adds crunch and freshness. Dice it small so nobody is getting huge chunks of celery or onion. Also if your onion seems to be really strong, rinse a cut piece in cool water before dicing.
  • Relish – This gives that punchy briny bite.
  • Seasonings – a combo of garlic powder, onions powder, kosher salt and black pepper is all you need.
  • Dijon Mustard – Just like the relish, it gives your tuna salad a tangy punch of flavor.
  • Cheese – Go for a melty cheese like cheddar, American or provolone.
  • Bread – Sourdough, white or wheat sandwich bread, or even a sturdy whole grain will work. For an open faced tuna melt opt for an English Muffin!

Step by Step How To Make The Recipe

Step 1

Mix your drained tuna with the tuna salad ingredients. Taste and tweak!

Step 2

Butter two pieces of bread and spoon on the tuna salad, top with a slice or two of cheese.

Step 3

Heat a skillet over medium low heat, add the sandwich, buttered side down, and grill the tuna melt, flip and continue until the sandwich is golden and the cheese is melty.

Step 4

Serve it up!

Serving Ideas

  • Pair it with tomato soup for that classic diner feel.
  • Serve with kettle chips for crunch.
  • Add a simple green salad with a sharp vinaigrette to balance the richness.
  • Slice it into strips for kids or serve open-faced on an English muffin for brunch

Recipe Tips To Remember

  • Use a high quality canned tuna packed in water, either a chunk white or whole white albacore tuna.
  • Make sure to press all the water out of the tuna before mixing the tuna salad, this will prevent your tuna melt from getting soggy.
  • Low and slow is key. You want the cheese to melt before the bread burns.
  • Don’t overfill the sandwich or it’ll spill out everywhere. Keep it to about ⅓ cup tuna salad per sandwich.
  • If your cheese isn’t melting fast enough, cover the pan with a lid for 30 seconds to trap some heat.
