Easy Zucchini Casserole Recipe (2024)

Easy garden-fresh Zucchini Casserole recipe to celebrate the summer zucchini season.

📕 What is this casserole?

I adapted this baked zucchini cheese casserole recipe from my aunt, who prepares a similar variation with fresh cream the southern french way.

So this is a very French zucchini dinner recipe!

This delicious lighter summer meal is also known as zucchini au gratin, as it is baked golden brown to perfection.

The Zucchini is baked soft in one dish and doesn't need pre-cooking, turn this recipe into a quick and easy sauteed zucchini recipe

You will love this healthy zucchini casserole with cheese if you are looking for a lighter gluten-free and low-carb vegetarian meal.

Another idea is to add meat to your dish, such as in this Keto Zucchini Casserole with ground beef.

💡 Choice of zucchini

You can pick medium-sized (8 inch/20 centimeters), large and epic monster large Zucchinis.

The size doesn't matter so much.

Store-bought Zucchini come in small and medium sizes, whereas homegrown Zucchini has a reputation for growing into massive vegetables.

The large ones tend to be less flavorful than the smaller ones, but homegrown Zucchini are usually anyway tastier (or so I believe).

You only need to cut out the spongy core in the large Zucchinis and you are good to go.

Try this recipe too with other Zucchini varieties, such as yellow Zucchini or round Zucchini.

Frozen Zucchini

If you have a whole frozen Zucchini, you can leave the vegetable to defrost in the fridge.

If you are rushing, place the zucchini to thaw in a closed bag and submerge into warm water.

Carefully press out any excess water or else the Zucchini gratin will turn out soggy.

To avoid sogginess, you can also add 1 Tablespoon of cornflour to the batter mixed in.

The cornflour will bind excess liquids and the gratin will turn out the best!

🔪 How to make it?

This is an easy zucchini casserole meal that comes together fairly quickly, too.

The zucchini slices will cook through in the casserole dish, making this a one-pan dish.

Follow the steps to prepare your own zucchini cheese bake from scratch.

Step 1

Cut out the center of your Zucchini if it's consistency is spongy.

Cut your Zucchini into slices and arrange in the casserole dish.

Step 2

In a mixing bowl combine the cream, egg, cheese and the seasoning.

Step 3

Pour the cheesy cream mixture over the zucchini in the casserole and drizzle with olive oil.

Bake golden brown.
