Step-by-Step Instructions
Prepare the Zucchini
Wash the zucchini thoroughly and slice each one in half lengthwise. Using a spoon, carefully scoop out the center to create zucchini boats while leaving enough flesh around the edges so they remain sturdy during baking.
Prepare the Filling
Peel and grate the potatoes. Squeeze out excess moisture using a clean kitchen towel. In a large bowl, combine the grated potatoes with drained tuna, onion, garlic, olive oil, paprika, oregano, salt, pepper, and half of the mozzarella cheese.
Mix until everything is evenly combined.
Fill the Zucchini
Arrange the zucchini boats in a lightly greased baking dish. Spoon the tuna and potato mixture into each zucchini, pressing gently to fill them completely.
Add the Cheese
Sprinkle the remaining mozzarella and Parmesan cheese evenly over each stuffed zucchini. This creates a beautifully golden topping as it bakes.
Bake
Preheat your oven to 375°F (190°C). Bake for 25–30 minutes, or until the zucchini is tender and the cheese is melted, bubbling, and lightly browned.
Garnish and Serve
Remove from the oven and allow the stuffed zucchini to rest for five minutes. Garnish with freshly chopped parsley before serving.
Expert Tips
- Choose medium-sized zucchini for even cooking.
- Drain the tuna thoroughly to avoid a watery filling.
- Remove excess moisture from grated potatoes.
- Freshly grated cheese melts better than pre-shredded cheese.
- Let the zucchini rest after baking to help the filling set.
Common Mistakes

Cover loosely with foil if the cheese browns too quickly.

Extra Cheesy
