Equipment

  • 1 Nonstick Skillet
  • 1 Mixing Bowl
  • 1 Spatula
  • Measuring spoons (set)
  • 1 Butter Knife

Ingredients
  

  • 12 ounces canned albacore tuna drained well, packed in water
  • 1/3 cup mayonnaise or half mayo, half plain Greek yogurt for a lighter option
  • 2 tablespoons finely diced red onion
  • 2 teaspoons freshly squeezed lemon juice
  • A pinch of dried oregano
  • Salt and freshly ground black pepper to taste
  • 4 slices thick-cut sandwich bread white, wheat, sourdough, or your choice
  • 4 slices cheese cheddar, provolone, Swiss, or preferred variety
  • Optional: sliced avocado for creaminess
  • Optional: sliced tomato for freshness

Instructions
 

  • Prepare the Tuna Mixture: In a medium mixing bowl, combine the drained tuna with mayonnaise, diced red onion, lemon juice, and oregano. Stir well until all ingredients are evenly incorporated. Adjust the texture by adding more mayonnaise if you prefer a creamier filling. Season the mixture with salt and pepper according to your taste preferences.
  • Assemble the Sandwiches: Lightly butter one side of each bread slice. On the unbuttered side of two slices, spread the prepared tuna mixture evenly. Layer a slice of cheese over the tuna, then add any optional toppings such as avocado or tomato slices. Place another slice of cheese on top of the toppings, and finish by covering with the remaining bread slices, buttered side facing out.
  • Cook the Tuna Melts: Heat a skillet over medium-low heat. Carefully place the assembled sandwiches into the skillet. Cook until the bottom slice of bread turns golden brown and the cheese begins to melt, about 3-4 minutes. Flip the sandwiches gently and cook the other side until it is also toasted and the cheese is fully melted, approximately another 3-4 minutes.

Notes

  • Tuna Quality: Use premium canned albacore tuna packed in water for a mild, flaky texture. Ensure it is thoroughly drained to prevent soggy sandwiches.
  • Cheese Options: Feel free to experiment with your favorite cheese varieties such as pepper jack for a spicy kick, or classic American for creaminess.
  • Bread Choices: Any thick-cut bread will work well; sourdough and rye add extra flavor complexity.
  • Topping Variations: Keep it simple or get creative by adding bacon, sprouts, jalapeños, or a dash of hot sauce to elevate your melt.
  • Alternate Cooking Methods: For an open-faced version, omit the top bread slice and broil until bubbly and golden. Alternatively, use an air fryer at 370°F for 2-3 minutes per side for a quicker, crispy finish.
  • Make-Ahead Tips: The tuna mixture can be prepared in advance and refrigerated for up to 4 days, perfect for meal prepping lunches.
