Tips & Substitutions
For a creamy texture, consider adding a dollop of sour cream or cream cheese to the mixture before baking. If you don't have baby Vidalia onions, sweet onions or even leeks can be good substitutes. To enhance the flavor, try adding garlic powder or fresh herbs like thyme or basil. Also, ensure to drain the zucchini thoroughly to avoid excess moisture in the casserole.
Serving Suggestions

It pairs beautifully with American recipes like Susan's Apple Cake for dessert, making it a perfect addition to any family gathering or potluck.

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in the oven at 350°F for about 15-20 minutes or until warmed through. Alternatively, you can microwave individual portions for about 1-2 minutes, checking to ensure it heats evenly.

Frequently Asked Questions
Can I use frozen zucchini for this recipe?
While fresh zucchini is recommended for the best texture, you can use frozen zucchini. Just be sure to thaw and drain it well to remove excess moisture. This may slightly alter the texture but will still work in the casserole.
What can I substitute for Cheddar cheese?
If you prefer a different cheese, mozzarella or Monterey Jack can be excellent substitutes, providing a milder flavor and good melt. For a sharper taste, opt for Gruyère or even a sprinkle of Parmesan on top for extra flavor.
Can I make this casserole ahead of time?
Absolutely! You can prepare the casserole a day in advance and store it in the refrigerator before baking. Just cover it tightly with foil. When ready to serve, bake it directly from the fridge, adding a few extra minutes to the baking time to ensure it heats through.
