What is a Tuna Melt Sandwich?

A tuna melt is a classic, simple sandwich of tuna salad, melted cheese, and toasted bread. According to legend, it was invented by accident in 1960 when a lunch counter chef spilled tuna salad onto a grilled cheese sandwich at a Woolworth's in Charleston, South Carolina. The pairing was a hit, and the sandwich quickly became popular for both its convenience and affordability.

A classic version typically features creamy tuna salad, melted cheese, crisp bread, and sometimes a pickle on the side. Read more about the tuna melt's origins on FoodRepublic.com.

Is a Tuna Melt Healthy?

This tuna melt is more comfort food for the soul than a health food, but the protein-rich tuna gives it some nutritional perks. I find it helps keep my blood sugar and energy more stable than a standard grilled cheese, though everyone's body is different. This is based on personal experience and not medical advice.

Tuna is also a source of heart-healthy omega-3 fats and other vitamins, but it's best enjoyed in moderation due to mercury content, so consult your doctor or dietitian for more guidance.

Ingredients

These simple ingredients make best tuna melt sandwich:

For the Tuna Salad:

• Tuna – The star of the show! I like light flaked tuna canned in water, such as skipjack, for its milder flavor and lower mercury content compared with albacore tuna (white tuna).
• Mayo – I use avocado oil mayo for a clean-eating option, but any favorite mayo works.
• Dijon mustard – Adds tang and a little kick to the tuna salad.
• Celery (optional) – Chopped celery gives fiber and crunch, but skip it if you're in a hurry.
• Scallions (optional) – Finely chopped scallions help balance the richness, though they're optional if you want to keep things simple.
• Seasoning – I always add a little sea salt and black pepper, and optionally a little garlic powder or garlic-infused olive oil for extra depth of flavor. You don't have to add much salt as the cheese also adds salty flavor.

For the Sandwich:

• Butter – Unsalted butter for toasting makes the bread crispy, golden, and indulgently comforting.
• Bread – The best bread for a tuna melt – I recommend white sourdough, though virtually any bread works, including gluten-free. Rye is another classic choice.
• Cheese – Looking for the best cheese for a tuna melt? I love marble or medium cheddar, but Monterey jack, Swiss or provolone also work. Slicing from a block about ¼-inch thick makes it extra cheesy and delicious.

Equipment You'll Need

Air Fryer Tuna Melt

Here's the equipment you'll need to make this easy recipe for tuna melt in the air fryer:

• Air fryer oven – needs a broil setting, like the Instant Pot Vortex Plus 10-quart Air Fryer, to toast the bread without drying it out
• Measuring cups and spoons
• Can opener – for opening canned tuna
• Small mixing bowl – for mixing tuna salad
• Fork – for mixing tuna salad
• Paring and butter knives – for slicing cheese and spreading butter
• Air fryer basket or tray – to hold the sandwich

Here's what you'll need to make the tuna melt on the stove:

• Lid or foil – to cover while toasting
• Measuring cups and spoons
• Can opener – for opening canned tuna
• Small mixing bowl – for mixing tuna salad
• Fork – for mixing tuna salad

How to Make a Tuna Melt Sandwich

This sandwich is comfort food made simple. The stovetop version tends to look a little prettier, with a golden, evenly toasted crust, while the air fryer version delivers maximum crispiness and is more set-it-and-forget-it friendly. Either way, you'll end up with melted cheese, savory tuna salad, and buttery toasted bread that will make your mouth water with every bite.

Air Fryer Oven Method

This air fryer tuna melt recipe is written for an air fryer oven with a Broil setting. In my tests, the regular air fry function tended to dry out the bread without giving it that classic golden finish. Broil, on the other hand, crisps the bread beautifully and melts the cheese just right.

Step #1: Preheat Air Fryer Oven

Set your air fryer oven to Broil at 400°F (200°C) and let it heat up for 10 minutes.

Step #2: Mix the Tuna Salad

In a small bowl, use a fork to combine the canned tuna, mayonnaise, Dijon mustard, and, if you like, celery and scallions for extra crunch and brightness. Season with salt, pepper, and a touch of garlic powder or garlic oil, if using.

Step #3: Butter the Bread

Slather one side of each slice of bread with butter.

Step #4: Build the Sandwich

• Place one slice of bread, butter side down, on your air fryer tray.
• Add a layer of cheese.
• Spread the tuna mixture evenly on top.
• Finish with the second slice of bread, butter side up.

Step #5: Toast it Up

Broil on the top rack of your air fryer for 8 minutes, flipping the sandwich horizontally halfway through, until the bread is golden and the cheese is melted. When using long sourdough bread, flipping it horizontally helps it hold together better.

Step #6: Enjoy

Slice in half (the best part is watching the cheese stretch) and enjoy right away.

Stovetop Method

Making a tuna melt on the stove is simple, but the key is gentle heat and a lid (or foil if you don't have an adequate lid). This way, the cheese gets melty while the bread toasts up perfectly.

Step #1: Preheat the Pan

Place a large frying pan or skillet over medium-low heat—hot enough that butter sizzles gently without browning too quickly.

Step #2: Make the Tuna Salad

Prepare the filling as described and shown in the air fryer method above.

Step #3: Butter the Bread

Butter one side of each slice of bread (pictured above).

Step #4: Build the Sandwich

• Place one slice of bread butter side down in the frying pan. Make sure your pan is hot enough before adding, or else it may not toast dark enough.
• Place cheese slices in a single layer on the bread.
• Spread the tuna mixture over the cheese slices.
• Close it up with the second slice of bread, butter side up.

Step #5: Toast to Perfection

Cover with a lid or foil (not pictured) to trap the heat and help the cheese melt. Cook 3–4 minutes per side, flipping horizontally, until the bread is golden brown and the cheese is gooey.

Step #6: Enjoy

Slice in half and enjoy while it's still warm and melty.

Variations

• Open Faced – Try an open-faced tuna melt for a lighter, lower carb option—just one slice of bread topped with tuna salad and cheese, broiled in your air fryer oven or on the stovetop until melty.
• Add-ins – Upgrade your classic tuna melt with simple add-ins: tomato or avocado slices, a fried or sliced hard-boiled egg on top, crispy bacon tucked into the tuna salad, or a spicy kick with hot sauce or chili flakes. These quick tweaks make a comforting sandwich even more enjoyable.
