The Perfect Baked Tuna Melt Recipe

Ingredients You’ll Need 

Here’s what you’ll need to create the ultimate baked Tuna Melt for two servings (adjust quantities as needed): 

• 2 cans of tuna in water (drained) 
• 2 tablespoons mayonnaise 
• 1 teaspoon Dijon mustard 
• 2 teaspoons relish or chopped pickles 
• Salt and pepper to taste 
• 4 slices of your favorite bread (try sourdough or whole wheat!) 
• 4 slices of sharp cheddar cheese (or any melty cheese you love) 
• Optional toppings: sliced tomatoes, avocado, or jalapeños.

Instructions 

1. Preheat the Oven 

Start by preheating your oven to 375°F (190°C). Line a baking sheet with parchment paper for easy cleanup.

2. Whip Up the Tuna Salad 

Combine your drained tuna, mayonnaise, Dijon mustard, relish, and a sprinkle of salt and pepper in a mixing bowl. Mix until creamy and well-incorporated.

3. Assemble the Melts 

• Lay your bread slices onto the prepared baking sheet.
• Spoon the tuna salad generously onto each slice, spreading it evenly.
• Add optional toppings like sliced tomatoes or avocado for extra flavor.
• Finish with one or two slices of cheese on top of each melt.

4. Bake to Golden Perfection 

Pop the baking sheet in the oven for about 8–10 minutes, or until the cheese is bubbling and golden brown. Watch closely—this is where the magic occurs!

5. Serve Hot and Enjoy! 

Use a spatula to transfer the Tuna Melts onto plates. Serve immediately and bask in the glory of this gooey, crunchy masterpiece.
