Notes & Tips
Add cheese layers: A little mozzarella or feta tucked between veggies makes it heartier.
Make ahead: Assemble ahead, refrigerate, and bake before serving.
Lighter topping: Swap breadcrumbs for almond flour for gluten-free.
Extra flavor: A drizzle of balsamic reduction before serving adds brightness.
Frequently Asked Questions
Q: Can I use yellow squash instead of zucchini?
Yes — it adds more color and blends beautifully.

It’s best fresh, but leftovers keep 3 days in the fridge. Freezing can make the veggies watery.
