Preheat the oven to 350°F. Wash and cut the zucchini into cubes.
To make the crumble, mix the flour, parmesan, diced butter, salt and pepper in a bowl using your hands. The mixture should be forming crumbs and hold together when pinched.
Butter a baking dish. Add the zucchini, pesto, salt and pepper and mix to combine.
Add the crumbled goat cheese on top, followed by the crumble mixture. Bake for 40 minutes, until the crumble is nice and golden.
Serve and enjoy!
