Preheat your oven to 375°F (190°C).
Cut the zucchinis in half lengthwise and scoop out the pulp, leaving the zucchini halves intact to form boats. Set the pulp aside.
Grease a baking tray with vegetable oil and place the zucchini halves on it. Season with salt, Italian herbs, smoked paprika, and pepper mixture.
In a pan, sauté the chopped onion in a little oil until softened. Add the grated carrot, potato, and the chopped zucchini pulp. Cook for about 5-7 minutes or until the vegetables are tender and the mixture has thickened slightly. Season with salt.
Spoon the veggie mixture into the hollowed zucchini boats and press gently to pack the filling.
Bake the zucchini boats for 25-30 minutes, or until the zucchini is tender and the filling is golden and lightly crispy.
Serve hot and enjoy!
