Can I Prepare Cheesy Zucchini Casserole Ahead of Time?

Yes. You can chop the zucchini, grate the cheese, and prepare the other ingredients in advance. For the best texture, store the prepared components separately in the refrigerator and assemble the casserole shortly before baking. You can also assemble the entire casserole ahead of time, but zucchini naturally releases water as it sits. Baking it soon after assembly helps prevent excess moisture and gives the finished zucchini bake a better texture.

How Can I Make Cheesy Zucchini Casserole Less Watery?

Start with firm, fresh zucchini and avoid adding unnecessary liquid. Cutting the zucchini into evenly sized, bite-sized pieces rather than very thin slices can also help the vegetables maintain their texture. For additional moisture control, lightly salt the chopped zucchini and let it rest before patting it dry. Remember that cheese can be salty, so adjust any additional seasoning accordingly. A little liquid at the bottom of a freshly baked Cheesy Zucchini Casserole is normal. Allowing the casserole to rest for several minutes before serving gives the creamy sauce time to settle.

What Is the Best Cheese for a Zucchini Casserole?

Cheddar is an excellent all-purpose choice because it melts beautifully and provides plenty of savory flavor. Mozzarella works well when you want a mild flavor and stretchy cheese, while Gruyère brings a richer, nutty quality. Parmesan is particularly useful for adding a salty, savory finish. You can also combine cheeses, such as cheddar and Parmesan or mozzarella and Parmesan, to create a more complex flavor and a delicious golden topping.

Instructions

Preheat the oven to 350°F (180°C) and prepare an oven-safe casserole or baking dish.
Wash the zucchini, trim the ends, and chop into evenly sized bite-sized pieces.
Place the chopped zucchini in the baking dish.
Add the sour cream and heavy cream, then stir until the zucchini is evenly coated.
Add 1/3 cup of the grated cheese and stir it through the zucchini mixture.
Sprinkle the remaining 1/3 cup grated cheese evenly over the top.
Bake for 20 to 25 minutes, or until the zucchini is tender and the cheese is melted and golden.

Notes

Use firm, fresh zucchini for the best texture and to minimize excess moisture.
Cheddar, mozzarella, Parmesan, Gruyère, or a blend of cheeses can be used.
Optional additions include garlic powder, black pepper, onion, fresh herbs, or red pepper flakes.
For a crunchy topping, sprinkle breadcrumbs over the cheese before baking.
For a richer casserole, replace part of the sour cream or heavy cream with softened cream cheese.
Some liquid in the bottom of the casserole is normal because zucchini naturally releases moisture as it cooks.
Store leftovers in an airtight container in the refrigerator and enjoy within 2 days.
