Ingredients You’ll Need
- 2 zucchinis, grated
- 1 can of tuna in water, drained (about 200g)
- 3 eggs
- 150g all-purpose flour
- 1 packet of baking powder
- 100ml olive oil
- 100g grated cheese (like emmental or cheddar)
- Salt and pepper to taste
- Herbs de Provence or dill (optional)
Substitution Options
- If you don’t have zucchini, try using yellow squash or even grated carrots.
- For the tuna, you can substitute with canned salmon or even finely chopped cooked chicken.
- Any type of shredded cheese will work, such as Gruyère or mozzarella.
Step-by-Step Preparation
Step 1: Preheat and Prep
Preheat your oven to 180°C (350°F). Grease a loaf pan so your cake doesn’t stick. In a large mixing bowl, whisk together the eggs and olive oil until they’re well combined and slightly frothy. The mixture should be smooth and silky, setting the stage for the rest of the ingredients.
Step 2: Combine Dry Ingredients
Add the flour and baking powder to the egg mixture. Stir gently until just combined. Be careful not to overmix, as this can lead to a tough cake. The batter should be thick but still pourable, like a luscious, creamy sauce.
Step 3: Mix in the Zucchini and Tuna
Fold in the grated zucchini, drained tuna, and grated cheese. Season with salt, pepper, and your choice of herbs. The zucchini will add a vibrant green color, while the tuna and cheese bring a wonderful, savory aroma. Mix everything together until the ingredients are evenly distributed.
Step 4: Bake to Perfection
Pour the batter into the prepared loaf pan. Smooth the top with a spatula. Bake for about 40-45 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. The kitchen will be filled with the mouthwatering scent of freshly baked goodness.
Step 5: Cool and Serve
Let the cake cool in the pan for a few minutes before transferring it to a wire rack. Allow it to cool completely before slicing. Serve it warm or at room temperature, perhaps with a side of mixed greens or a simple tomato salad. The contrasting textures and flavors will make every bite a joy.
Chef’s Secret: A Special Tip
For an extra burst of flavor, sprinkle some lemon zest over the top of the cake before baking. The citrusy notes will complement the zucchini and tuna beautifully, adding a bright, refreshing touch.

Storage Tips
Store the Zucchini Tuna Cake in an airtight container in the refrigerator for up to 3 days. It’s best to let it come to room temperature before serving, as the flavors will be more pronounced. If you want to freeze it, wrap it tightly in plastic wrap and then in aluminum foil. It will keep in the freezer for up to 2 months. Thaw it in the fridge overnight before serving.
For a quick and tasty snack, slice the cake and reheat it in the oven for a few minutes. The edges will crisp up, and the inside will stay moist and delicious. You can also freeze individual slices for quick grab-and-go meals or snacks.
When reheating, avoid using the microwave, as it can make the cake rubbery. Instead, use the oven or a toaster oven to maintain the cake’s texture and flavor. The oven method ensures that the cake retains its moisture and fluffiness, making it as good as new.
Tips and Advice
- Grate the zucchini just before adding it to the batter to prevent it from releasing too much liquid.
- Use a high-quality canned tuna for the best flavor. Look for one packed in water rather than oil.
- Don’t overmix the batter; it should be just combined to ensure a light and fluffy texture.
Presentation Tips
For a beautiful presentation, garnish the Zucchini Tuna Cake with fresh herbs like dill or parsley. You can also add a dollop of Greek yogurt or a drizzle of garlic aioli on top of each slice. Serving it on a colorful platter with a side of sliced tomatoes and cucumbers will make it look even more inviting.

Common Mistakes to Avoid
Mistake 1: Squeezing Too Much Liquid Out of the Zucchini
While it’s important to remove excess moisture from the zucchini, don’t overdo it. Zucchini needs to retain some of its natural moisture to keep the cake moist. To avoid this, simply squeeze the zucchini lightly in a clean kitchen towel or cheesecloth. Pro tip: save the zucchini juice and use it in a smoothie or soup for a nutrient boost.
Mistake 2: Overmixing the Batter
Overmixing can lead to a tough and dense cake. Once you add the dry ingredients to the wet, mix just until the batter is combined. A few lumps are okay! This will ensure your Zucchini Tuna Cake is light and fluffy.
Mistake 3: Not Checking the Doneness
Every oven is different, so it’s essential to check the cake’s doneness. Insert a toothpick or cake tester into the center. If it comes out clean, the cake is done. If it’s still wet, give it a few more minutes. Overcooking can dry out the cake, so keep a close eye on it.
Mistake 4: Forgetting to Let the Cake Cool
It’s tempting to dig in right away, but letting the cake cool for a few minutes after baking is crucial. This allows the cake to set and makes it easier to slice. Plus, the flavors will meld together better, giving you a more delicious result.
Mistake 5: Using Flavored Canned Tuna
Always opt for unflavored, canned tuna in water. Tuna packed in oil or with added spices can alter the taste of your Zucchini Tuna Cake. The simple, mild flavor of plain tuna works best with the other ingredients.
FAQ
