How to Make It
Here’s how to create your casserole masterpiece.
Preheat the oven
Set your oven to 375°F (190°C) so it’s hot and ready when your casserole is assembled.
Prepare the zucchini
Wash and slice the zucchini into thin rounds. If you prefer, you can also grate the zucchini for a different texture.
Sauté the vegetables
In a large skillet, add a tablespoon of olive oil over medium heat. Add the zucchini and corn, sautéing for about 5-7 minutes until just tender. Season with salt, pepper, and any herbs you like.
Mix the base
In a large bowl, combine the sautéed vegetables with beaten eggs, half of the shredded cheese, breadcrumbs, and any additional spices. Stir until everything is well mixed.
Transfer to a baking dish
Grease a 9×13 inch baking dish and pour the mixture in, smoothing it out evenly.
Add the topping
Sprinkle the remaining cheese over the top, followed by additional breadcrumbs if desired. This will create a delicious crunchy crust.
Bake
Place the casserole in the preheated oven and bake for about 30-35 minutes, or until the top is golden and bubbly.
Cool and serve
Once out of the oven, let the casserole cool for a few minutes before slicing. This allows it to set and makes serving easier.
How to Store It
Fridge: Store for up to 3 days in an airtight container.
Freezer: Yes, freeze for extended freshness.
Reheat: Microwave for 2-3 minutes or bake at 350°F (175°C) for 15 minutes.
