Ingredients
-
Potatoes – 1.2 kg (about 3 lbs), peeled and cubed
-
Canned tuna – 170 g (6 oz), drained
-
Capers – 1 tablespoon, drained
-
Black or green olives – 100 g (4 oz), chopped
-
Parmesan cheese – to taste, finely grated
-
Breadcrumbs – as needed, for binding and coating
-
Olive oil – for drizzling and baking
-
Salt and pepper – to taste
Step-by-Step Cooking Directions
1. Cook the potatoes
Peel and cube the potatoes. Add them to a large pot of salted water, bring to a boil, and cook until tender—about 15–20 minutes. Drain and mash while still warm.
2. Prepare the mix-ins
Drain the canned tuna and use a fork to flake it apart. Roughly chop the olives and drain the capers.
3. Combine the ingredients
In a large bowl, mix the mashed potatoes with the tuna, capers, and olives. Season with salt and black pepper to taste. Add grated Parmesan and enough breadcrumbs to bind the mixture—about 1/2 cup to start.
4. Shape the cakes
Form the mixture into small, palm-sized patties. If it’s sticky, dampen your hands with a bit of water. For extra crunch, you can lightly coat the patties with more breadcrumbs.
5. Bake the tuna cakes
Preheat the oven to 200°C (400°F). Place the cakes on a parchment-lined baking sheet, drizzle them lightly with olive oil, and bake for 20 minutes, or until golden brown and crisp.
6. Serve hot
Serve warm with a wedge of lemon, a drizzle of olive oil, or your favorite dipping sauce.

Ingredient Spotlight: Capers
Capers are the unripe flower buds of the caper bush, typically pickled and preserved in brine. Their sharp, salty tang adds a punch of flavor that balances the richness of tuna and potatoes. They’re low in calories, high in antioxidants like quercetin and rutin, and a staple in Mediterranean cooking. Use them sparingly—just a tablespoon goes a long way!
