    Happy 1st March Folks! I know it's been a while since Christmas, although it just feels like only yesterday, don't you think?

    Back then, I devised this tuna sweetcorn cakes recipe, a batch of delicious oven baked tuna sweetcorn cakes that quickly became a household favourite.

    I was faced with several mountains platefuls of leftover mashed potatoes in the fridge and wondering just what to do with them.

    Rather than freeze them in portions as I normally would, I thought I would try and come up with something else different.

    There's usually always a spare tin of tuna as a backup in the cupboard as well as plenty of bags of frozen vegetables like sweetcorn in the freezer.

    Pairing those together seemed like a good idea, and the result was these simple tuna sweetcorn cakes. A perfect budget meal that's quick, satisfying, and family-friendly.

    This was not only a great outcome after Christmas when I was skint but also a great outcome now, as I'm still making them and saving money in the process!

    I used frozen sweetcorn here, as that's all I had available.

    It's cheap after all and handy for bulking up recipes like these easy tuna sweetcorn cakes.

    You could use peas or any other chopped up leftover vegetables you might have to hand.

    My wholemeal breadcrumbs come from a bag of frozen leftover bits of bread that I keep in the freezer.

    When I need breadcrumbs, I take this bag out, take sufficient bread bits out to defrost and blitz them to a breadcrumb consisency in my food processor.

    Any breadcrumbs left over just go back into the bag and into the freezer. As you know, nothing and I mean NOTHING goes to waste in this kitchen! 🙂

    You'll find that a lot of other fish cake recipes are fried too, rather than oven baked as these are.

    Oven baking these healthy tuna sweetcorn cakes makes them healthier and less calorific whilst still keeping them seriously tasty.

    Are these tuna sweetcorn cakes healthy? Yes, because these tuna sweetcorn cakes are oven baked rather than fried they are healthy. They're also made with wholemeal breadcrumbs, and packed with protein and fibre from the tuna and vegetables.

      What an excellent way to use up leftover mashed potatoes! We often have a can of tuna in the cupboard, too, but I've never thought about pulling it out for the leftover potatoes. And the breadcrumb topping? I bet it provides the perfect crunch! I'm tempted to go make more mashed potatoes now...just so I can have leftovers for these tuna cakes. Haha! Great idea, and I hope you and Lynne have a wonderful weekend, my friend!

        It's amazing what you can do with some left over mashed potatoes and a can of tuna. I was walking home from work yesterday and I knew I had some of these in the freezer. It was a really snowy day and I couldn't be bothered cooking anything so I just re-heated a couple of these in the oven and served them in between rolls. They tasted amazing and I can't wait to see what other ideas of dishes I can come up with, with mashed potato! Ha ha! Hope you have a great weekend too!

      Neil, I love everything about this recipe, how easy it is to make, the delicious combo of ingredients but I really love how healthy it is too being baked and not fried. Perfect lunch recipe...this I have got to try. Thank you for the delicious recipe. Have a great weekend:)

        Perfect for lunches Ashika, yes! And perfect for packed lunches too. I haven't tried myself but I'm pretty sure that the cakes could easily be re-heated at work if there's a microwave available and paired with a simple salad this would be absolutely delicious. I don't think I'd get any work done with looking forward to my lunch! Ha ha! ๐Ÿ˜†

      Another wonderful idea. I haven't tried those chickpea cakes/fritters yet, and now you've brought my favorite tuna...and corn...and potatoes...in one dish. Hard to decide. How cruel, Neil! ๐Ÿ˜‰
