When you need dinner fast and the fridge is looking a little bare, these crispy tuna, corn, and potato cakes are the kind of pantry meal that saves the night. They’re made with canned tuna, leftover cold mashed potatoes, a handful of corn, and a quick binder of egg and breadcrumbs—nothing fancy, just practical ingredients that turn into something really satisfying.
The outside gets golden and crisp in a skillet, while the inside stays tender and savory. The key is starting with cold mashed potatoes (warm potatoes make the mixture too loose), and giving the shaped cakes a short chill if they feel soft. I also like keeping the heat at medium so the cakes brown evenly without burning before the centers heat through. Serve them with a quick sauce or a simple salad, and dinner is done.
Why You’ll Love This Recipe
- Uses simple pantry staples (canned tuna, potatoes, corn, breadcrumbs).
- Great way to use up leftover mashed potatoes.
- Crispy edges with a soft, flavorful center.
- Fast: minimal prep and quick stovetop cooking.
- Easy to scale up for meal prep or family dinners.
- Practical tip: chilling firms the mixture so the cakes flip without falling apart.
Ingredients
- 2 cans (5 oz / 142 g each) tuna, drained
- 2 cups (about 300 g) cold mashed potatoes
- 1 cup (165 g) corn kernels (fresh, frozen, or canned and drained)
- 1 large egg
- 1/2 cup (55 g) breadcrumbs
- 2 scallions, thinly sliced
- 1/2 teaspoon garlic powder
- 1/2 teaspoon salt
- 1 tablespoon (15 ml) olive oil (for pan-frying)
Ingredient Notes
- Tuna: Any canned tuna works. If it’s packed in water, drain well and squeeze lightly so the cakes don’t get wet.
- Mashed potatoes: Cold potatoes hold shape best. If your mash is very buttery/creamy, you may need a bit more breadcrumbs to firm the mixture.
- Corn kernels: Frozen corn is great—thaw and pat dry. Canned corn works too; just drain well.
- Breadcrumbs: Plain breadcrumbs keep the flavor flexible. Panko will make the cakes slightly crispier, but either works.
- Scallions: Add a fresh bite. If you don’t have them, finely diced onion or chives are good substitutes.
- Olive oil: You’re using just enough to crisp the cakes. If your pan runs dry, add a small splash more between batches.
Kitchen Tools Needed
- Large mixing bowl
- Fork (or clean hands) for mixing
- Measuring cups and spoons
- Plate or small tray (for chilling the cakes)
- Nonstick skillet or well-seasoned cast iron pan
- Thin spatula (helps with flipping)
- Paper towels (optional, for draining)
Step-by-Step Instructions
-
Mix the cake mixture.
In a large bowl, combine the drained tuna, cold mashed potatoes, corn, egg, breadcrumbs, scallions, garlic powder, and salt. Mix until the tuna is evenly distributed and the mixture holds together when you squeeze a little in your hand. -
Check the texture.
If it feels very soft or sticky, stir in 1–2 more tablespoons breadcrumbs (about 7–14 g). This happens more often with very creamy mashed potatoes or extra-wet tuna. -
Shape into cakes.
Divide the mixture into 10 cakes (about the size of your palm). Gently press them into even patties—about 1/2 to 3/4 inch (1–2 cm) thick. -
Chill briefly (optional but helpful).
If the cakes feel delicate, place them on a plate and chill for 10 minutes. This small step makes flipping much easier. -
Heat the skillet.
Heat 1 tablespoon (15 ml) olive oil in a nonstick skillet over medium heat until it shimmers. -
Cook until crisp and golden.
Add the cakes in a single layer (work in batches if needed). Cook for 3–4 minutes per side, until the bottoms are deeply golden and crisp. Flip carefully and cook the second side until crisp and the centers are hot. -
Serve hot.
Transfer to a plate (you can blot lightly with paper towels if you’d like) and serve right away while they’re at their crispiest.
Pro Tips
- Start with cold potatoes. Warm mashed potatoes make the mixture loose and harder to shape.
- Drain tuna and corn really well. Extra moisture is the main reason these cakes fall apart.
- Don’t rush the flip. Wait until the first side is properly browned; it releases from the pan more easily.
- Use medium heat, not high. Medium gives you crisp edges without scorching the breadcrumbs.
- Batch cook without crowding. Crowding traps steam and softens the crust.
Common Mistakes
- Using warm mashed potatoes: The mixture turns sticky and won’t hold its shape.
- Not draining well: Wet tuna or corn makes the cakes fragile and mushy.
- Flipping too soon: If the crust hasn’t formed, the cakes can break.
- Cooking on high heat: Outside browns too fast while the center stays cool.
- Making cakes too thick: Thick cakes can brown before they heat through.
Variations
- Spicy: Add 1/4 teaspoon cayenne or a pinch of red pepper flakes to the mix.
- Herby: Mix in 1–2 tablespoons chopped parsley or dill (about 4–8 g).
- Cheesy: Add 1/3 cup shredded cheddar or mozzarella (about 35–40 g) for a richer center.
- Extra crispy: Swap in panko breadcrumbs, or lightly coat the outside of each cake with a dusting of breadcrumbs before frying.
Serving Suggestions
- Serve with a simple dipping sauce like tartar sauce, lemony mayo, or plain Greek yogurt mixed with a little garlic powder and salt.
- Add a green salad or coleslaw on the side for crunch.
- These also work nicely tucked into a sandwich or wrap with lettuce and sliced tomato.
Storage Instructions
- Refrigerator: Store cooled cakes in an airtight container for up to 3 days.
- Freezer: Freeze cooked cakes in a single layer, then transfer to a freezer bag/container for up to 2 months. Thaw overnight in the fridge for best texture.
Reheating Tips
- Best: Reheat in a skillet over medium heat with a tiny drizzle of oil, 2–3 minutes per side, until hot and crisp again.
- Oven/air fryer: 375°F (190°C) for about 8–12 minutes, flipping halfway.
- Microwave: Works in a pinch, but the cakes will soften rather than stay crisp.

Frequently Asked Questions
Can I use freshly made mashed potatoes?
Yes, but let them cool completely first. Warm potatoes make the mixture too soft and harder to fry without breaking.
What kind of tuna is best for tuna cakes?
Solid or chunk tuna both work. The most important part is draining well so the mixture isn’t watery.
Why are my potato cakes falling apart?
Usually it’s excess moisture or not enough binding. Drain tuna/corn thoroughly, add a bit more breadcrumbs, and chill the shaped cakes for 10 minutes before cooking.
Can I bake these instead of pan-frying?
You can, though they won’t get quite as crisp. Bake at 425°F (220°C) on an oiled sheet pan for about 10–12 minutes per side, flipping carefully.
Can I make the mixture ahead of time?
Yes. Cover and refrigerate the mixture for up to 24 hours, then shape and cook when ready.
Conclusion
These tuna, corn, and potato cakes are one of those low-effort, high-reward dinners—crispy, filling, and made from ingredients I almost always have on hand. Keep the mixture cold, don’t rush the browning, and you’ll get sturdy cakes with a lovely crisp crust every time.
