Ingredients
- Tuna: packed in water or oil allowing for a moist and flaky base for the salad with plenty of protein
- Mayonnaise or Greek yogurt: provides creaminess and binds the ingredients together choose Greek yogurt for a lighter touch
- Dijon mustard: adds a tangy depth balancing the creaminess
- Garlic powder: brings subtle savoriness
- Onion powder: imparts a mild sweetness enhancing the flavor profile
- Salt and black pepper: for seasoning to taste
- Fresh jalapeño: finely diced with seeds removed for mild heat and more if you like it spicy
- Sharp cheddar cheese: shredded adds meltiness and a sharp tangy flavor
- Optional green onions: chopped for brightness and a mild onion crunch
- Bread: sourdough or whole wheat is sturdy enough to hold the filling without getting soggy and adds flavor
- Butter: for grilling provides richness and helps achieve that golden crispy exterior
Instructions
- Make the Tuna Salad:
- In a mixing bowl gently combine tuna mayonnaise or Greek yogurt Dijon mustard garlic powder onion powder salt and black pepper. Stir in the diced jalapeño shredded cheddar cheese and green onions if using. Mix just enough to incorporate evenly without mashing the tuna completely.
- Assemble the Sandwiches:
- Spread butter evenly on one side of each bread slice. Place the buttered side down on a preheated skillet over medium heat. Sprinkle a generous amount of shredded cheddar cheese on one slice of bread. Spread the tuna salad mixture evenly over the cheese layer. Top with the second slice of bread with the buttered side facing up.
- Grill the Tuna Melts:
- Cook each sandwich for about 3 to 4 minutes per side pressing gently using a spatula. Watch for the bread turning golden brown and crisp and the cheese inside melting beautifully. Take care to cook on medium heat so the cheese warms through without burning the bread. Remove sandwiches from heat and let them rest for one minute to allow flavors to settle.
- Serve and Enjoy:
- Slice the sandwiches in half and serve immediately. These go wonderfully with classic pickles a handful of chips or even a light side salad.

One of my favorite things about this recipe is how the sharp cheddar melts into little pockets of gooey goodness surrounded by spicy tuna. It reminds me of casual family dinners where simple ingredients come together to make something everyone loves.
Storage tips
Keep leftover tuna salad in an airtight container in the fridge for no more than three days to keep it fresh and safe. Reheat grilled sandwiches carefully in a skillet over low heat or use an air fryer for a few minutes to crisp them back up without drying out the filling. Freezing is not advised because thawing impacts the texture of the tuna mixture making it less appealing.
Ingredient substitutions
Try canned salmon instead of tuna for a different but equally satisfying flavor. You can swap shredded cheddar for pepper jack or Swiss to change the cheese profile and spice level. Use Greek yogurt completely or in part for mayo if you prefer a lighter option. Whole grain or rye bread works beautifully to add different textures and flavors.
Serving suggestions
Pair these melts with classic tomato soup for a nostalgic cozy combo. Crispy fries or kettle chips add a crunchy contrast that complements the creamy filling. A fresh side salad with lemon vinaigrette lightens the meal and adds a refreshing balance to the cheesy richness.

These melts are a fast crowd pleaser that come together in minutes. Tweak the spice and cheese to make them your own.
