Tuna Potato Bake with Cheese Method

  • Put the kettle on to boil
  • Peel potatoes and slice them very thinly.
  • Put the potatoes, with a dash of salt, into a saucepan
  • Cover potatoes with boiling water and bring to the boil. Simmer for about 12 minutes - until the potatoes start to break up when you poke them with a fork.

Tuna Potato Bake Tip

Tip: If you have a vegetable steamer, then just steam the potato slices, I find it's quicker, the potatoes have a better consistency, there's less steam produced and I find it easier to rinse out a vegetable steamer than washing up a saucepan (I have limited space in the kitchen and my vegetable steamer is about 1/2 the size of a saucepan). Additionally, steaming your potato slices will retain the vitamins... I like to leave the skins on too!

Tuna Potato Bake with Cheese Method

  • Pre-heat the oven to about 200°C/375°F
  • Strain the potatoes and put them in a large mixing bowl then mash the potatoes to taste. For me this means dropping in a large spoon of Flora Light and some black pepper, but for others of you this might mean mixing with butter and possibly a dash of milk or cream.
  • Once the spuds are mashed, open the tin of tuna and add the tuna to the potato - pick the tuna out of the can in small bits with a fork.
  • Mix the tuna/mash together and spoon the mix into ovenproof dishes. How many you use depends on how much you think a portion is - and what dishes you have!
  • Sprinkle grated cheese on top of the tuna/mash mix
  • Place the dish(es) into the oven and bake for about 20 minutes. The cheese should be melted and slightly browned.
  • Remove from the oven and serve your tuna potato bake while it's still hot.

Once made, this tuna potato bake can be refrigerated, in a covered dish, and will be fine to eat up to 3-4 days later. You can eat it cold, or you can microwave the tuna potato bake for 3-4 minutes to reheat it. It will also freeze well.

And there you have it: Tuna Mashed Potato Bake achieved quick and easy!

Serving Suggestions

  • just a splash of brown sauce
  • serve with baked beans, pease or green beans
  • serve with a side salad


Any portions of tuna and mashed potato bake that you don't eat immediately can be put covered into the fridge and used up to 3 days later by microwaving it for 4-5 minutes. Or you could freeze it into portions.

I like this a lot. Tuna potato bake is cheap, easy to prepare, keeps for days and tastes great.

I hope you enjoy this Tuna Potato Bake with Cheese recipe as much as I do.

Can You Freeze Tuna Potato Bake?

This can be frozen. Simply cover it and put it in the freezer. To defrost, either remove it from the freezer the night before and put it in the fridge overnight, or bake from frozen, or you can microwave it to defrost it, then bake it (to save time over baking from frozen).

Tuna Casserole with Potato

If you're reading this in the US you'll know this as a tuna casserole with potato. In the UK we use the term "bake", whereas Americans call this dish a tuna casserole.

In the UK a casserole is meat/vegetables swimming in gravy, baked in the oven in a casserole dish. If a dish is firm and uses a white sauce (among others) then we use the term "bake".

Alternative Methods

If you want to keep it easy, then instead of baking this Tuna & Potato Bake in the oven, why not just mix the tuna and mash, form into neat little cakes and fry them?

Tuna & Potato Fishcakes

After shaping the tuna/potato mix into neat individual cakes, coat in flour or breadcrumbs.

I'd put the cheese on the inside so it's a melted layer!

For speed, you could finish the mix off under a medium grill instead of the oven.

I've just made this Tuna & Mashed Potato Bake, but this time I had some spare tomatoes that needed using up.... so I sliced them and put them on the top before baking It turned out even better! Served with a splash of my favourite brown sauce. mmmm

Growing up my grandmother made my now 87 year old mother and her brothers a tuna pie (top and bottom crust) with mashed potatoes but no vegetables. Mom grew up and still lives in Westbrook Maine. Mom regrets never getting that recipe. Would anyone by some miracle have such a recipe? We have a salmon pie recipe but this was tuna. What would you use for spices? Thank you.

Yes, you can make a white sauce and add that to the tuna, then add the potatoes - that'd be awesome!

I made this last night and it was absolutely gorgeous, and went down very well. I will definitely make this again, due to the cheap nature of the ingredients.

I made one slight alteration, which was to include a chopped onion in the mix, gave it a bit of crunch. Was lovely if you like that sort of thing!
