Why We Love This Recipe

We love this recipe because it’s quick, easy, and comforting. It uses pantry staples like canned tuna and mayonnaise, yet delivers a restaurant-quality sandwich when paired with sourdough and broiled cheese. It’s versatile too—you can keep it classic or add your own creative touches, like sliced tomatoes, caramelized onions, or even a spicy kick of jalapeños.

The beauty of the tuna melt lies in its texture contrast: crunchy sourdough, creamy tuna salad, and stretchy melted cheese. Every bite feels indulgent but approachable. It’s also budget-friendly and kid-approved, making it a go-to recipe that works for almost every occasion.

Why It’s a Must-Try Dish

• Course: Main Course (Sandwich)
• Cuisine: American Comfort Food

Ingredients

• 2 (5-oz) cans tuna, drained
• 2–3 tablespoons mayonnaise
• 1 tablespoon Dijon mustard (optional)
• 1 celery stalk, finely chopped
• 2 tablespoons red onion, finely chopped
• 1 teaspoon lemon juice
• Salt and freshly ground black pepper, to taste
• 4 slices sourdough bread
• 4 slices cheddar cheese (or Swiss, provolone, or your favorite)
• 2 tablespoons butter, softened

Quick Directions

1. Mix tuna with mayonnaise, mustard, celery, onion, lemon juice, salt, and pepper.
2. Spread butter on sourdough slices and layer tuna mixture with cheese.
3. Grill on a skillet until golden and cheese is melted.
4. Slice and serve warm.

Step-by-Step Preparation Method:

Step 1: Make the Tuna Salad

• In a bowl, combine tuna, mayonnaise, mustard (if using), celery, onion, lemon juice, salt, and pepper.
• Mix well until creamy and evenly combined.

Step 2: Assemble the Sandwich

• Butter one side of each slice of sourdough bread.
• On the unbuttered side of two slices, layer tuna salad evenly.
• Place cheese slices on top, then close the sandwich with the second slice of bread, buttered side facing out.

Step 3: Cook the Sandwich

• Heat a skillet or griddle over medium heat.
• Place sandwiches in the pan and cook for 3–4 minutes per side, pressing lightly with a spatula, until the bread is golden brown and the cheese has melted.

Step 4: Serve

• Slice diagonally and serve hot.

How to Serve

• Serve the tuna melt with a side of potato chips, French fries, or a crisp green salad.
• Pair with tomato soup for the ultimate comfort-food combo.
• Garnish with pickles or a small side of coleslaw for added crunch.

Tips for this Recipe:

1. Don’t Overcrowd the Pan: Cook 1–2 sandwiches at a time for even browning.
2. Use Room-Temperature Butter: Spreads more evenly on bread.
3. Low and Slow Heat: Prevents burning the bread before cheese melts.
4. Cheese Choices: Cheddar is classic, but provolone, mozzarella, or pepper jack add new flavors.
5. Toast Bread Slightly First: For extra crunch, pre-toast sourdough before assembling.

Variations:

• Spicy Tuna Melt: Add sriracha or jalapeños to the tuna mix.
• Avocado Tuna Melt: Add sliced avocado for creaminess.
• Italian-Style Melt: Use mozzarella, sun-dried tomatoes, and basil.
• Open-Faced Tuna Melt: Assemble on one slice of bread and broil until cheese bubbles.

Freezing and Storage

• Refrigeration: Store assembled sandwiches (uncooked) in an airtight container for up to 1 day. Cooked tuna melts can be refrigerated for up to 2 days, but they lose crispness.
• Freezing: Not recommended, as mayonnaise and bread don’t freeze well.
• Reheating: Warm in a skillet or oven (350°F) for 8–10 minutes to restore crunch.

Special Equipment Needed

• Skillet or griddle
• Spatula
• Mixing bowl
• Sharp knife
