 Q & A

Q: How do I prevent a watery casserole?
Salting and drying the zucchini + briefly sautéing removes excess moisture.

Q: Can I make it ahead of time?
Yes! Assemble, cover, and refrigerate up to 24 hours before baking.

Q: Can I freeze it?
Yes, but texture is best fresh. Freeze baked casserole up to 2 months.

Q: Can I make it low-carb?
Skip breadcrumbs — the rest is naturally low-carb.

Q: What other cheeses work well?
Gruyère, Monterey Jack, or feta for a Mediterranean twist.

 Cozy Tip

Add cooked mushrooms or spinach for extra veggies, or a pinch of chili flakes if you like gentle heat.
