Ingredients You’ll Need for the Perfect Tuna Melt

You probably already have most of these ingredients at home. Here’s what you’ll need:

• 2 cans (7 oz each) albacore tuna in water, drained
• ½ cup mayonnaise
• ¼ cup sour cream
• 1 tablespoon Dijon mustard
• 1 stalk celery, chopped
• 2 tablespoons finely chopped red onion
• ⅕ cup sweet pickle relish
• 1½ tablespoons fresh chopped parsley, divided
• ½ teaspoon dried dill weed
• ¼ teaspoon freshly ground black pepper
• 6 slices of your favorite bread: sourdough, rye, wheat, pumpernickel
• 12 thin slices of tomato
• 1¼ cups shredded cheddar cheese

If you’re leaning into healthy lunch options, you can also try this Healthy Tuna Melt Wrap for a lighter spin.

Let’s Talk About the Bread

I’ve made this recipe with sourdough, whole wheat, and even pumpernickel—they all work beautifully.

The key is to choose a bread that’s sturdy enough to hold up under the creamy tuna salad and gooey cheese.

If you’re using really soft sandwich bread, I recommend toasting it a little longer to avoid a soggy bottom.

How to Make a Tuna Melt (Step-by-Step)

Here’s exactly how I make these cheesy, crispy tuna melt sandwiches at home:

1. Preheat your oven

Set your oven to 400°F (200°C) so it’s nice and hot when you’re ready to bake.

2. Mix up the tuna salad

In a large bowl, combine the drained tuna, mayo, sour cream, mustard, celery, red onion, relish, 1 tablespoon of parsley, dill, and pepper.

Mix everything together until it’s creamy and well-blended.

Tip: Taste as you go. Sometimes I like to add a little extra mustard or dill if I’m in the mood for a zingier flavor.

3. Toast your bread

Lightly toast the slices of bread in a toaster or under the broiler.

This helps create a crisp foundation and keeps the sandwich from getting soggy.

4. Assemble your melts

• Place the toasted bread slices on a baking sheet.
• Divide the tuna mixture evenly between them.
• Add 2 slices of tomato to each.
• Sprinkle generously with shredded cheddar.

5. Bake to perfection

Slide the tray into the oven and bake for 10–15 minutes, or until the cheese is melted and bubbling and the sandwich is warmed through.

If you like a slightly crispy cheese topping, pop them under the broiler for the last minute or two—just keep a close eye so they don’t burn.

6. Garnish and serve

Sprinkle the remaining chopped parsley on top before serving.

That final touch of green makes everything look a little more fresh and homemade.

Tuna Melt Variations to Try

One of the things I love most about this recipe is how easy it is to tweak.

Here are a few fun ways to switch it up:

Cheese swaps

• Swiss, provolone, or mozzarella all melt beautifully.
• Add a little Parmesan on top for an extra layer of flavor.

Looking for more melty goodness? Try these crowd-pleasing cheesy broccoli rice casserole or creamy cowboy soup—both loaded with comforting flavors.

Bread options

• Try a baguette, English muffin, or even naan.
• Turn it into a grilled sandwich by pressing it on a skillet with butter.

Add some crunch or spice

• Toss in some chopped pickles, jalapeños, or banana peppers.
• Add a dash of hot sauce to the tuna mixture for a kick.

Make it low-carb

• Skip the bread and serve the tuna melt mixture in bell pepper halves, then bake.
• Or serve it over a bed of lettuce as a tuna melt salad.

Make-Ahead Tips for Busy Days

One of my go-to time-savers is mixing the tuna salad a day or two ahead.

Just store it in an airtight container in the fridge.

That way, when you’re ready to eat, all you need to do is assemble and bake.

You can even prep a double batch and use it for lunches throughout the week.

Pair it with make-ahead sides like this fresh cranberry salsa or pomegranate guacamole to round out the meal.

What to Serve with Tuna Melts

These sandwiches are pretty filling on their own, but here are a few easy sides to serve with them:

• Potato chips or sweet potato fries
• Tomato soup or a light veggie soup
• Cucumber or green salad with vinaigrette
• Pickles or coleslaw for a little crunch

If you’re hosting guests or planning ahead, serve this alongside a Greek hummus platter for a balanced and shareable lunch.

Storage and Reheating

If you have leftovers, store them in an airtight container in the fridge for up to 2 days.

To reheat:

• Pop them back into a 375°F oven for about 10 minutes.
• Or reheat in a toaster oven to bring back that crispness.

I don’t recommend microwaving them—it makes the bread soggy and the cheese rubbery.
