Ingredients for a Garlic Bread Tuna Melt
The Tuna Salad
Well-drained solid white albacore tuna, mayo, Dijon, sweet relish, chopped pickle, celery, red onion, fresh dill, a splash of pickle juice, garlic powder and black pepper.
The Garlic Butter
Softened butter, finely grated garlic, Parmesan, chopped parsley and a pinch of salt.
The Bread and Cheese
Thick-cut sourdough, sharp cheddar and provolone.
Swap note: Use gluten-free bread for a gluten-free tuna melt. For a lighter tuna salad, swap half the mayo for Greek yogurt.
How to Make a Tuna Melt
Step 1: Make the tuna salad
Drain the tuna really well, then mix it with the mayo, Dijon, relish, pickle, celery, red onion, dill, pickle juice, garlic powder and pepper.
Step 2: Make the garlic butter
Stir together the softened butter, grated garlic, Parmesan, parsley and a pinch of salt.
Step 3: Assemble in the skillet
Spread the garlic butter on one side of each slice of sourdough. Heat a skillet over medium-low heat, place the bread butter-side down and layer on the cheddar and provolone. Spread the tuna salad on top and close the sandwich.
Step 4: Grill until golden
Cook 3 to 4 minutes until deeply golden and crispy. Carefully flip and cook the other side until golden and the cheese is melted, covering the pan for a minute if needed.
Step 5: Rest and slice
Let it sit for a minute so the filling sets, then slice and serve.
Carly’s Expert Tips
- Drain the tuna really well. Extra liquid makes the sandwich soggy.
- Keep the heat medium-low so the cheese melts before the garlic bread burns.
- Cheese against the bread acts like glue and keeps the tuna in place.
- Cover the pan for a minute to help everything melt.
Make It Your Own
- Open-faced: Broil the tuna and cheese on garlic bread for an open-faced melt.
- Spicy: Add sliced jalapeños or a drizzle of sriracha mayo.
- Tomato: Layer in a thin slice of tomato before closing.
- Different cheese: Swiss, pepper jack or American all melt beautifully.
Make-Ahead and Meal Prep: Make the tuna salad and garlic butter up to 3 days ahead and keep them in the fridge. Assemble and grill when you are ready to eat.
What to Serve With a Tuna Melt
Pair your tuna melt with a cup of Roasted Tomato Basil Soup, kettle chips, a pickle spear or a simple side salad.
Storing and Reheating
A tuna melt is best eaten right away. Store leftover tuna salad in an airtight container in the fridge for up to 3 days.
To reheat a leftover sandwich, warm it in a skillet over low heat or in the air fryer at 350°F for 3 to 4 minutes.
