Ingredients

Use simple, pantry-friendly ingredients that come together into something truly satisfying.

Canned tuna (preferably solid white albacore, drained well)
Mayonnaise
Dijon mustard
Red onion, finely chopped
Celery, finely chopped
Lemon juice
Salt
Black pepper
Bread slices (sourdough, white, or whole wheat)
Cheese slices (cheddar, Swiss, provolone, or American)
Olive oil or softened butter (for brushing bread)
Fresh parsley (optional garnish)

Instructions

Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or foil for easy cleanup.
In a mixing bowl, combine drained tuna, mayonnaise, Dijon mustard, red onion, celery, lemon juice, salt, and black pepper. Mix gently until creamy and well combined, but don’t overmix.
Arrange bread slices in a single layer on the prepared sheet pan. Lightly brush or spread olive oil or butter on one side of each slice.
Flip the bread slices so the oiled side is down. Spoon an even amount of tuna mixture onto each slice.
Top the tuna with a slice of cheese, making sure it covers most of the surface for even melting.
Place the sheet pan in the oven and bake for 10–12 minutes, or until the cheese is fully melted and bubbly.
For extra browning, switch the oven to broil and cook for an additional 1–2 minutes, watching closely to prevent burning.
Remove from the oven, garnish with chopped parsley if desired, and serve immediately.

Choosing the Best Tuna for Tuna Melts

Not all tuna is created equal. For the best tuna melt sandwich, opt for solid white albacore packed in water. It has a firmer texture and cleaner flavor that holds up well to baking. Chunk light tuna is more affordable and works fine too, but it tends to be softer and more shredded.

Always drain your tuna thoroughly. Excess liquid can make the mixture watery and prevent the bread from crisping properly in the oven.

Best Cheeses for Sheet Pan Tuna Melts

Cheese is the soul of a good tuna melt. Here are some great options:

Cheddar: Sharp and classic, melts beautifully.
Swiss: Mild, nutty, and pairs well with tuna.
Provolone: Creamy and smooth with excellent melt.
American: Ultra-melty and nostalgic.
Pepper Jack: Perfect if you like a little heat.

You can even mix cheeses for a more complex flavor profile.

Tips for Perfect Oven Baked Tuna Melts

Toast protection: Brushing the bread with oil or butter creates a barrier that prevents sogginess.
Even portions: Spread tuna evenly so every bite is balanced.
Don’t overload: Too much tuna can weigh down the bread and affect texture.
Watch the broiler: Cheese can go from golden to burnt quickly.
Serve hot: Tuna melts are best enjoyed fresh from the oven.

Variations and Flavor Twists

One of the best things about this easy tuna melt recipe is how adaptable it is.

Mediterranean Tuna Melt:
Add chopped olives, capers, and a sprinkle of oregano. Use provolone or mozzarella.

Spicy Tuna Melt:
Mix a little sriracha or chili flakes into the tuna and top with pepper jack cheese.

Healthy Tuna Melt:
Swap half the mayo for Greek yogurt and use whole grain bread.

Open-Faced vs. Classic:
Keep them open-faced for lighter eating, or sandwich two slices together after baking.

Serving Suggestions

Sheet pan tuna melts are satisfying on their own, but they pair beautifully with simple sides:

Tomato soup or creamy vegetable soup
Crispy oven fries or sweet potato wedges
Green salad with lemon vinaigrette
Pickles or coleslaw for crunch and acidity

These sides balance the richness of the tuna and cheese perfectly.

A Little Cultural Context: Why Tuna Melts Are Timeless

The tuna melt rose to popularity in mid-20th-century America, when canned tuna became widely available and affordable. It was a practical, protein-rich option that could be dressed up or down depending on what was in the pantry. Over time, it earned its place on diner menus and in home kitchens alike.

Today, the sheet pan version reflects how modern cooking adapts classics to fit busy lifestyles—same comfort, less effort.

Storage and Reheating

Tuna melts are best fresh, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat in the oven at 350°F (175°C) for 5–7 minutes to restore crispness. Avoid microwaving if possible, as it can make the bread soggy.
