This Tuna Melt is the ULTIMATE bagel – a tuna sandwich with bells on.

It’s an amazing snack, lunch or quick dinner that takes almost as much time and effort as a regular sarnie, but it’s like heaven to eat. 

Of course, if bagels are not your thing, you could use the same ingredients and method on another vessel instead, from regular bread to a baguette, pittas or sourdough.

Or even serve it all up on a jacket potato.

How we came up with this recipe

A Tuna Melt is so satisfying and delicious, and it’s a great recipe to use when you want to make something quick but a bit more special than a regular cold sandwich. 

I wanted to make a Tuna Melt on a bagel instead of bread, because it adds a bit more robust texture and it feels more like a full meal

There’s also a choice of bagel flavour so you can customise it a little. An onion bagel or wholemeal bagel will work well.

Tuna Melt Ingredients

Ingredients to make bagel tuna melts.
  • Bagels – Choose whichever type of savoury ones you like best
  • Tinned tuna – I prefer in spring water, but choose whichever is your preference
  • Mayonnaise – I use reduced fat, but it’s up to you
  • Red onion – You could use spring onions if you prefer
  • Sweetcorn – Tinned sweetcorn is fine for this
  • Grated mozzarella – Or you could use any other cheese that melts well

How to make Tuna Melts

Step 1 of making tuna melt bagels. All the ingredients in a glass bowl, ready to be mixed.

1. Mix the tuna, sweetcorn, onion, mayo and plenty of salt and pepper together in a bowl.

Step 2 of making tuna melt bagels. Bagels on a board.

2. Cut the bagels in half and toast the outer side of each under a medium grill.

Step 3 of making tuna melt bagels topping with tuna mixture and sweetcorn mixture.

3. Turn the bagel halves over, top with the tuna mixture. (I use a fork to press it down).

Step 4 of making tuna melt bagels topped with cheese, ready to go in the oven.

4. Sprinkle over the cheese and pop under a medium grill for 5 minutes until the cheese is melted.


  • Bread – Feel free to change the bagel for normal bread or another kind of bread you like


Tuna Melts are best eaten immediately, when they’re still warm and the cheese is gooey. However, if you don’t manage that, you could:

In the fridge You can keep this recipe in the fridge for 3 days. Reheat it in the oven before serving.

Be aware that if you heat it in the microwave it might be a little floppy. You can also eat it cold.

In the freezer I wouldn’t recommend freezing this recipe as it’s definitely best eaten straight away, however, if you do, make sure you reheat it fully in the oven, covered in foil.

Top tip

You could add chilli sauce or chilli flakes on top for a bit of heat should you prefer it spicy.


What’s best to serve with Tuna Melt?

If you’d like to make this as a main meal, you could serve it alongside a bowl of hot Tomato Soup, or even some Homemade Chips.

For a lighter meal, go for a simple side salad or coleslaw.
