Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.

For The Creamy Tuna Mixture

The tuna filling is based on my perfect tuna salad recipe that is always on high rotation in our house!

• Tuna – canned. Drain the tuna well.
• Whole egg mayonnaise – or kewpie mayo – see tips.
• Celery and red onion – finely diced, they both add a delicious crunch in every bite!
• Pickles or dill cucumbers – drained and diced. Being stored in brine, these miniature cucumbers add an all important salty, acidic flavour to the tuna filling – not to be missed!
• Dill and chives – chopped.
• Dijon mustard – the traditional mustard of France. Dijon is made from crushed mustard seeds and has a creamy texture, a spicy taste and smooth finish, with a more complex flavour than regular yellow mustard.
• Salt and pepper – to season.

For The Sandwiches

• Sourdough bread – see tips.
• Burger cheese or cheddar – the best cheese to use in this recipe is either slices of burger cheese, sharp cheddar cheese, Monterey jack, pepper jack, Swiss cheese, American cheese or any other melty cheddar cheese. You could also use grated mozzarella cheese if you prefer.
• Butter.
• Parmesan cheese – finely grated (optional).

Equipment Required

Besides the usual utensils needed to chop and mix ingredients, the only equipment required depends on how you want to cook your tuna melt sandwich.

You may use a:

• Frying pan – my preferred way for the crispiest, crunchiest tuna melt!
• Sandwich press, or
• Air fryer.

Step By Step Instructions

Make sure you cook these toasties until the sourdough is golden and crispy, and the cheese is melted and oozy…..that’s true comfort food!

Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.

Step 1 – Prepare The Tuna Filling

Drain the tuna well and place it in a large bowl.

Add the remaining filling ingredients – whole egg mayonnaise, chopped celery, diced red onion, dill pickles, fresh dill and chives, Dijon mustard, salt and black pepper.

Mix until all the ingredients are combined in the bowl. Set aside.

Step 2 – Assemble The Sandwiches

Lay out the slices of bread on a bench or board and lightly spread each slice with butter.

Place the slices of cheese on every second slice of bread.

Spoon tuna salad mixture on top of each cheese slice in a single layer and spread evenly.

Place the remaining bread slices on top of the filling. Lightly spread butter over the top and bottom of the sandwiches (for the ultimate crunch!!!)

Step 3 – Cook The Tuna Melt

HIGHLY RECOMMENDED!!! Frying Pan Method – (the ultimate method for crunchy tuna melts!!) – heat a frying pan over medium-low heat. Fry the sandwiches in batches until golden brown and crunchy and the cheese has melted, turning over partway through.

Sandwich Press Method – cook the sandwiches in batches until golden brown and crunchy.

Air Fryer Method – cook in batches on 180 degrees celsius for 5 – 10 minutes, turning over partway through. Note: All air fryers are different so cooking time may vary. If using the air fryer, lightly spray the outside of the bread with cooking oil spray rather than spreading with butter.

Once cooked, remove the tuna melt from the pan (or sandwich press or air fryer), and sprinkle a little finely grated parmesan cheese over the crispy bread (optional), then cut and serve whilst warm.

Trust me, these are the BEST sandwiches!

Expert Tips

Here’s my top tips for the best tuna melt!

• Ensure you drain all of the liquid from the tuna well before using to prevent the sourdough from becoming soggy.
• Whole egg mayo or kewpie mayo are the best options for a thick and creamy filling.
• Cheese – use burger cheese, cheddar cheese or any melting cheese.
• I recommend using sourdough bread, rather than regular bread, as it gives the tuna melt a deliciously crunchy texture and is firm enough to hold the filling in place. 
• Cooking method – you can cook these tuna melts in a frying pan, a sandwich press or an air-fryer. For the ultimate golden crunch, melty goodness and gooey cheese, I recommend using a frying pan and lightly buttering the outside of the bread before cooking!
• Serving suggestions – A tuna melt pairs perfectly with crunchy potato chips, pickles, coleslaw or a fresh green salad for balance. For something warm, try a comforting bowl of tomato soup, crispy sweet potato fries, or roasted potatoes.
• Storing – the tuna melt filling can be stored in an airtight container in the fridge for up to 3-4 days. However once cooked, enjoy your tuna melt straight away!
• This recipe is not suitable for freezing.
