Be sure to squeeze the shredded zucchini very well in a clean kitchen towel to remove excess moisture, which is key to preventing a soggy kugel and helping it hold its shape.
The potato acts as a natural binder and should not be skipped, as it absorbs moisture and creates a more structured, sliceable texture.
For the best results, let the kugel rest for 10–15 minutes after baking so it firms up before slicing.
If the mixture feels too wet before baking, you can add a small amount of additional matzo meal to help absorb excess moisture.
For a crispier finish, place the kugel under the broiler for the last few minutes, watching closely.
This kugel can be made ahead by baking, cooling completely, and refrigerating for up to 24 hours before reheating in a 350°F oven.
It also freezes well for up to 2 months; thaw overnight in the refrigerator and reheat in the oven for best texture.
The recipe is naturally dairy-free and suitable for Passover when using matzo meal, or you can substitute gluten-free breadcrumbs or panko outside of the holiday if preferred.
