Table of Contents
One of my favorite nostalgic comfort foods is a toasty tuna melt. It’s always on my list to order at a diner, but it’s simple and easy to prepare at home. It’s a great way to take my classic tuna salad and transform it into a delicious leveled-up grilled cheese sandwich. It only takes a few minutes to cook for a quick lunch or dinner.
My tuna melt sandwich recipe starts with thick slices of bread and layers of cheddar cheese, juicy tomatoes, and a creamy protein-packed filling. Buttering the bread ensures golden brown and crisp pieces. Serve with a side of potato wedges, crispy chips, or a dill pickle.
Key ingredients
- Canned Tuna: Use three 5-ounce cans of tuna in water and drain well. White albacore tuna will give a lighter color and firmer texture. Light tuna will be darker in color and softer in texture, with a more robust fish flavor.
- Mayonaise: The emulsified egg and oil sauce adds creaminess to the salad.
- Vegetables: Celery and red onions add a delicious crunch and freshness.
- Relish: Add tanginess with sweet pickle relish, dill pickle relish, or chopped pickles.
- Herbs: Sliced green onions and chopped parsley add an herbaceous taste.
- Mustard and Citrus: Dijon and lemon juice add a hint of spice and tartness.
- Seasonings: Salt and pepper enhance the savory taste.
- Bread: Purchase thick pieces of white, wheat, or sourdough bread, about ½ inch thick. This will create a sturdy sandwich.
- Cheese: Add about 1 ounce of mild or sharp cheddar—two slices or ¼ cup grated.
Make the salad
Use a fork to break up the tuna into smaller flakes. This will mainly be needed if using solid white tuna. Combine the fish with the mayonnaise, celery, red and green onions, relish, dijon mustard, parsley, lemon juice, salt, and pepper.
Mix until the tuna mixture is combined. It yields about 2 cups, ½ cup per sandwich. The salad can be prepared up to 5 days in advance, making it ideal for meal prep.
Butter the bread
The fat and milk solids in butter help the bread develop a golden brown hue and flavorful surface. Use softened butter to make it easy to spread a thin layer on one side or each piece. I also find it easy to brush on melted butter for an even coating, especially if the bread tends to be more delicate.
You can skip this step. However, the bread will be drier. If you want to reduce the amount of butter, you can lightly grease the pan each time the sandwich is flipped. Vegetable oil can also be used. I’ve also used mayonnaise to spread onto the bread for a crisp surface, but it will have a slightly eggy flavor.
Build the sandwich
To ensure that the cheese starts to melt first, it’s important to layer the sandwich a certain way. Add the cheese slices or grated cheese to the bread so it’s on the bottom. This gives it closer contact with the hot pan. Add the tomatoes on top, followed by ½ cup of tuna salad.
Place the other piece of bread on top. Now you’re ready to toast the sandwich! Alternatively, add cheese to the top and bottom for extra gooeyness. This also helps the sandwich stick together if you add additional ingredients to the tuna salad.
Cook the sandwich
The trickiest part of making a tuna melt is the timing of toasting the bread and melting the cheese. I prefer a nonstick pan or cast iron skillet that retains the heat well. Preheat the skillet over medium-low heat, then add the sandwich buttered-side down with the cheese on the bottom first.
Cover the sandwich with a lid to trap the steam. This will help melt the cheese and slightly warm the tuna salad. The moderate heat will gradually toast the bread, but check for doneness after 2 minutes. Adjust the heat down if needed.
Carefully flip the sandwich over, cover, and cook until the other side of the bread is golden brown, about 2 to 3 minutes. Slice and enjoy immediately for a hot meal.

Frequently asked questions
The key ingredients are thick pieces of bread, tuna salad, and cheddar cheese. The sandwich is toasted until the bread is golden brown and crisp and the cheese is melted. It can be served as an open-faced sandwich, especially if adding a lot of toppings.
Try sour cream or plain Greek yogurt instead of mayonnaise in the tuna salad. This will add a tangier flavor. Mashed avocado is a good dairy-free substitute.
Any type of melting cheese to give the characteristic cheese pull and help bind the sandwich. Cheddar, mozzarella, Monterey Jack, swiss, gouda, Gruyere, or Colby are good choices. Avoid dry-aged cheese like Parmesan.
Toasting tuna melts in the oven
To cook multiple tuna sandwiches simultaneously, bake them in the oven. Heat the oven to 400ºF (200ºC). Evenly space them on a large rimmed baking sheet. Bake on the middle rack for about 5 to 8 minutes, until the bread is toasted and the cheese is melted. The hot enclosed environment will quickly dry the surface of the bread and melt the cheese.
