Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

4 medium zucchini
1 tablespoon olive oil
1 small onion, finely chopped
2 cloves garlic, minced
200 grams mushrooms, finely chopped
2 cups fresh spinach, chopped
1 cup ricotta cheese
1/2 cup shredded mozzarella cheese
1/4 cup grated parmesan cheese
1 teaspoon dried oregano
1/2 teaspoon salt
1/2 teaspoon black pepper
1/4 teaspoon chili flakes (optional)

Directions

Preheat your oven to 180°C (350°F). Line a baking tray with parchment paper or lightly grease it with oil.

Wash the zucchini and slice them in half lengthwise. Using a spoon, carefully scoop out the center to create a hollow “boat” shape, leaving a thin border around the edges. Set the scooped flesh aside as it will be used in the filling.

Heat olive oil in a pan over medium heat. Add the chopped onion and cook for about 2–3 minutes until softened. Stir in the garlic and cook for another 30 seconds until fragrant.

Add the chopped mushrooms to the pan and cook until they release their moisture and become tender, about 5–6 minutes. Stir occasionally to prevent sticking.

Next, add the chopped spinach and the reserved zucchini flesh. Cook until the spinach wilts and excess moisture evaporates. Season the mixture with salt, pepper, oregano, and chili flakes if using. Remove from heat and allow it to cool slightly.

In a bowl, combine the cooked vegetable mixture with ricotta cheese, half of the mozzarella, and half of the parmesan. Mix well until creamy and evenly combined.

Place the hollowed zucchini halves on the prepared baking tray. Spoon the filling generously into each zucchini boat, pressing it gently to ensure it stays in place.

Sprinkle the remaining mozzarella and parmesan cheese on top of each stuffed zucchini.

Bake in the preheated oven for 20–25 minutes, or until the zucchini is tender and the cheese is melted and lightly golden.

Remove from the oven and allow to cool slightly before serving.

Servings and timing

This recipe serves 4 people, with each serving consisting of two zucchini halves. Preparation time is approximately 15 minutes, and cooking time is around 25 minutes, bringing the total time to about 40 minutes.

Variations

You can customize this recipe in several ways to suit your taste preferences. Add cooked shredded chicken for extra protein or swap ricotta with cream cheese for a richer texture. For a dairy-free version, use a plant-based cheese alternative. You can also experiment with herbs such as basil or thyme to enhance the flavor profile. Adding chopped olives or sun-dried tomatoes can bring a Mediterranean twist to the dish.

Storage/Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the zucchini boats in an oven-safe dish and warm at 170°C (340°F) for about 10–15 minutes until heated through. You can also reheat them in a microwave for 2–3 minutes, though the texture may be softer. Avoid freezing, as zucchini tends to release excess water when thawed.
