Tuna Melt Grilled Sandwich (Printable)

Creamy tuna salad with melted cheese on golden grilled bread

# What You'll Need:

→ Tuna Salad

01 - 1 (5 oz) can tuna in water, drained
02 - 2 tablespoons mayonnaise
03 - 1 teaspoon Dijon mustard
04 - 1 small celery stalk, finely diced
05 - 1 tablespoon red onion, finely diced
06 - Salt and black pepper to taste

→ Sandwich Assembly

07 - 4 slices sandwich bread (white, whole wheat, or sourdough)
08 - 1 tablespoon butter, softened
09 - 4 slices Swiss or cheddar cheese
10 - 2 slices tomato (optional)

# How-To Steps:

01 - Combine drained tuna, mayonnaise, Dijon mustard, celery, and red onion in a mixing bowl. Mix thoroughly until all ingredients are evenly distributed. Season with salt and black pepper to taste, adjusting flavors as needed.
02 - Spread softened butter evenly on one side of each bread slice. This buttered surface will become the exterior of the sandwich, creating a golden, crispy crust when cooked.
03 - Layer half the tuna salad onto the unbuttered side of two bread slices, spreading to cover the surface. Add tomato slices if desired, then top each with 2 cheese slices. Place remaining bread on top with buttered side facing outward.
04 - Heat skillet over medium heat. Place sandwiches in the pan and cook for 3-4 minutes per side, pressing gently with spatula. Flip once the bottom is golden brown and cheese begins melting. Continue cooking until bread is evenly toasted and cheese is fully melted throughout.
05 - Remove sandwiches from skillet and let rest for 30 seconds. Cut each sandwich diagonally in half and serve immediately while hot and cheesy.

# Expert Advice:

01 -
  • The combination of warm melted cheese and cool creamy tuna creates this perfect temperature contrast that hits every comfort button
  • It comes together in under 20 minutes but tastes like something from a proper diner
  • You probably have everything in your kitchen right now
02 -
  • Medium heat is your friend here because high heat burns the bread before the cheese melts
  • Draining the tuna thoroughly is the difference between a sandwich that holds together and one that falls apart
  • A good press with your spatula helps everything meld together beautifully
03 -
  • Mayo can be swapped for Greek yogurt but the texture will be slightly less creamy
  • Add chopped pickles or fresh dill to the tuna salad for extra brightness
  • Let the sandwich rest for a minute before slicing so the cheese sets slightly
