I do something like this a lot https://oukosher.org/recipes/potato-carrot-and-zucchini-kugel-pareve/

You can swap in other vegetables--sweet potato, parsnips, yellow squash, whatever works for you. But I'd try to keep the wetter vegetables like zucchini and the dryer ones like potato or carrot in the same ratio as the recipe calls for.

Do you have a recipe to share? TIA
