- 3 eggs
- 150 g of all-purpose flour
- 100 g of grated emmental, cheddar, or your choice of cheese
- 1/2 packet of baking powder
- 50 ml of olive oil
- 1 onion
- 1 tablespoon of mustard
- Salt and pepper to taste

Preparation Section
Step 1: Preparing the Zucchini
Start by washing and peeling the zucchinis. If you prefer, you can leave the skin on for added color and texture. Grate the zucchinis using a fine grater and place them in a colander. Sprinkle a pinch of salt over them and let them sit for about 10 minutes to release excess water. Squeeze out the excess liquid before using.
Step 2: Preparing the Other Ingredients
Finely chop the onion. In a pan, heat a little olive oil and sauté the onion until it turns golden and translucent. This step brings out the sweet, caramelized flavor of the onion, adding depth to the cake.
Step 3: Making the Cake Batter
In a large bowl, crack the eggs and beat them lightly. Add the olive oil and mustard, stirring well to combine. Gradually add the flour and baking powder, mixing until you get a smooth batter. Stir in the grated cheese, drained and flaked tuna, squeezed zucchini, and sautéed onions. Season with salt and pepper to taste.
Step 4: Baking the Cake
Preheat your oven to 180°C (350°F). Pour the batter into a greased or parchment-lined loaf pan. Smooth the top with a spatula. Bake for about 45 to 50 minutes, or until the cake is golden brown and a knife inserted into the center comes out clean.

Storage
Store your Zucchini Tuna Cake in an airtight container in the refrigerator for up to 5 days. If you want to freeze it, wrap individual slices in plastic wrap and aluminum foil, and store in the freezer for up to 3 months. Simply thaw and reheat in the oven when you’re ready to enjoy.
For the best texture, allow the cake to cool completely before storing. This helps prevent moisture from condensing and making the cake soggy.
If you’re planning to serve the cake the next day, consider brushing the top with a little olive oil before refrigerating. This keeps the cake moist and adds a nice sheen to the surface.
Tips and Advice
For a crisper crust, brush the top of the cake with a little olive oil before baking. Also, make sure to preheat your oven fully to ensure even cooking.

Common Mistakes to Avoid
Mistake 1: Over-Salting the Zucchini
When you salt the zucchini to remove excess water, be careful not to overdo it. Too much salt can make the final dish overly salty. Rinse the zucchini under cold water after draining to remove excess salt if needed.
Mistake 2: Not Squeezing Enough Water from the Zucchini
If you don’t squeeze out enough water from the zucchini, your cake can end up soggy. Make sure to press the grated zucchini firmly in a clean kitchen towel to remove as much water as possible.
Mistake 3: Over-Baking the Cake
Over-baking can dry out the cake and make it tough. Keep an eye on the cake and test it with a toothpick or knife around the 45-minute mark. If it comes out clean, your cake is done.
Mistake 4: Using Canned Tuna with Added Salt
Some canned tuna comes with added salt, which can make your cake too salty. Opt for canned tuna in water or unsalted varieties to control the salt content better.
Mistake 5: Not Preheating the Oven Fully
Always preheat your oven to the correct temperature before baking. This ensures that the cake bakes evenly and rises properly. A cold oven can lead to uneven cooking and a less-than-perfect result.
