Tuna Potato Cakes

Crispy on the outside, soft on the inside. A great way to turn canned tuna and potatoes into something that feels like a real meal.

Prep: 15 min Cook: 10 min Total: 25 min Servings: 4 (makes about 8 cakes) Difficulty: Medium

Allergens: Contains Fish (tuna), Eggs, Gluten (flour).

Ingredients

  • 2 cans (5 oz each) tuna, drained
  • 3 medium potatoes, peeled and boiled (or 1 can of potatoes, drained and mashed)
  • 1 egg
  • ¼ cup flour
  • 3 tablespoons vegetable oil (for frying)
  • ½ medium onion, finely diced

Optional Extras

  • Salt and pepper to taste
  • Garlic powder
  • 2 tablespoons crushed cereal (Chex or corn flakes) for extra crunch

Equipment

  • Large pot (for boiling potatoes)
  • Skillet or frying pan
  • Mixing bowl
  • Fork or potato masher
  • Spatula

Instructions

  1. If using fresh potatoes: Peel and cut into chunks. Boil in a pot of water for 15–20 minutes until a fork slides through easily. Drain and mash until smooth. Let cool for a few minutes.
  2. Add the drained tuna, diced onion, egg, and flour to the mashed potatoes. Mix everything together with a fork until evenly combined. Season with salt, pepper, and garlic powder if you have them.
  3. Scoop about ¼ cup of the mixture and shape it into a flat patty (like a small hamburger). Repeat until all the mixture is used — you should get about 8 cakes.
  4. If you want extra crunch, press each side of the patty into crushed cereal before frying.
  5. Heat the vegetable oil in a skillet over medium heat. The oil should shimmer but not smoke.
  6. Place the cakes in the skillet. Don't crowd the pan — cook in batches of 3–4 at a time.
  7. Cook for 3–4 minutes per side until golden brown. Flip carefully with a spatula.
  8. Place finished cakes on a plate. Serve warm.

Notes

  • Canned chicken swap: Works the same way. Drain it well and break it up before mixing.
  • Serving idea: These are good on their own, with canned vegetables on the side, or on bread like a sandwich.
  • Make ahead: Form the patties and refrigerate for up to a day before frying.
  • Egg-free? Skip the egg and add an extra tablespoon of flour. Handle the cakes gently — they'll be more fragile but still work.
  • Gluten-friendly version: Substitute the flour with cornstarch. Use crushed rice-based cereal for the coating.
