How to Make Cheesy Zucchini Bake

1. Prepare the Zucchini

Wash the zucchini thoroughly and slice it into thin, even rounds.

Try to keep the slices similar in thickness so they cook evenly.

Place the zucchini slices in a bowl and season lightly with salt and black pepper.

2. Sauté the Zucchini

Heat a little olive oil in a large skillet over medium heat.

Add the zucchini slices and cook for several minutes, turning occasionally.

You don't need to cook them until completely soft. The goal is simply to remove some of their moisture and give them a little flavor before baking.

Once lightly tender, remove the zucchini from the heat.

If the zucchini releases a lot of liquid, drain the excess moisture.

This step is important because zucchini contains a lot of water, and removing some of that moisture helps prevent the finished casserole from becoming watery.

3. Prepare the Creamy Mixture

In a large bowl, whisk together the eggs and milk or cream.

Add the minced garlic, oregano, Italian seasoning, salt, and black pepper.

Stir in the shredded mozzarella and Parmesan cheese.

Mix everything until well combined.

The eggs help the casserole set while the cheese creates a creamy, savory texture.

4. Assemble the Casserole

Lightly grease a baking dish with olive oil or cooking spray.

Arrange the sautéed zucchini slices in the dish.

Pour the creamy egg and cheese mixture evenly over the zucchini.

Use a spoon or spatula to make sure the mixture reaches between the zucchini slices.

Sprinkle a little additional mozzarella or Parmesan over the top if desired.

5. Bake

Place the baking dish in a preheated oven and bake until the center is set and the top becomes golden brown.

The exact cooking time can vary depending on the depth of your baking dish and the amount of moisture in the zucchini.

The casserole is ready when the center no longer looks liquid and the cheese on top is beautifully golden.

6. Rest Before Serving

Remove the casserole from the oven and allow it to rest for several minutes before slicing.

This gives the egg and cheese mixture time to set, making the casserole easier to serve.

Garnish with fresh parsley or basil if desired.

Serve warm.
