How to Make Easy Shredded Zucchini Casserole
Step 1: Prep the Zucchini
Start by shredding your zucchini using a box grater or food processor. Place it in a colander, sprinkle with salt, and let it sit for 10–15 minutes. Then, using your hands or a cheesecloth, squeeze out as much moisture as possible. This is key to avoiding a watery casserole.

Bake for 35–40 minutes, or until the top is golden and the center is set. Let it rest for 5–10 minutes before slicing.
