Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in the oven at 350°F (175°C) for about 15-20 minutes or until warmed through. You can also microwave individual portions for 1-2 minutes, but the oven will help maintain the crispiness of the topping.

Frequently Asked Questions

Can I use frozen zucchini for this recipe?

While fresh zucchini is recommended for best texture, you can use frozen zucchini. Just ensure it's thawed and drained well to remove excess moisture before mixing it with the other ingredients.

What can I substitute for Parmesan cheese?

If you don’t have Parmesan cheese, you can substitute with Pecorino Romano for a sharper flavor or use a dairy-free cheese alternative if you prefer a vegan option. Nutritional yeast is another great option for a cheesy flavor without dairy.

Can I make this dish ahead of time?

Yes, you can prepare the mixture a day in advance and store it in the refrigerator. Just pour it into the baking dish and bake it fresh before serving for the best texture and flavor.
