Slice the zucchinis lengthwise into thin strips (about 1/8 inch thick). You can use a mandolin slicer for even slices.
Lightly salt the zucchini slices and let them sit for about 10 minutes to release excess water. Pat them dry with a paper towel.
Make the Filling:
In a bowl, combine the ricotta, mozzarella, Parmesan, basil, parsley (if using), minced garlic, salt, and pepper. Mix well until all ingredients are combined.
Assemble the Rolls:
Lay a zucchini strip flat on a clean surface.
Spread a small spoonful of the cheese mixture along one edge of the zucchini slice.
Roll up the zucchini slice tightly to form a roll, securing the filling inside.
Bake the Rolls:
Place the zucchini rolls in a baking dish.
If desired, spoon a bit of marinara sauce over the rolls.
Brush the tops of the rolls with a little olive oil.
Bake for about 20-25 minutes, or until the rolls are golden and the cheese is melted.
Serve:
Garnish with extra fresh herbs or a sprinkle of Parmesan before serving.
