Ingredients
- Cooking spray, for preparing the baking dish
- 4 cups shredded zucchini
- 1 onion, chopped
- 1 (8.5-ounce) package dry corn muffin mix
- 2 large eggs, beaten
- ½ teaspoon salt
- ¼ teaspoon ground black pepper
- 8 ounces Cheddar cheese, shredded
Instructions
Preheat the oven to 350°F (175°C).
Wash the zucchini thoroughly and pat it dry with a clean kitchen towel.
There is no need to peel the zucchini. The skin is tender and edible, and leaving it on adds color and texture to the casserole.
Using the large holes of a box grater, shred the zucchini until you have approximately 4 cups.
Because zucchini naturally contains a significant amount of water, check how wet the shredded zucchini is. If it is releasing a lot of liquid, place it in a clean kitchen towel and gently squeeze out some of the excess moisture.
You do not need to make the zucchini completely dry. A little moisture helps keep the casserole tender, but removing excessive liquid helps prevent a soggy texture.
Peel the onion and chop it into small pieces.
For a quick version of this recipe, the chopped onion can be mixed directly into the casserole.
If you want a deeper, sweeter onion flavor, you can sauté the onion in a skillet over medium heat for several minutes before adding it to the mixture.
Allow sautéed onions to cool slightly before combining them with the eggs.
Place the shredded zucchini and chopped onion in a large mixing bowl.
Toss them together until the onion is evenly distributed throughout the zucchini.
This ensures that every portion of the casserole contains a good balance of vegetables.
If you are adding any optional herbs or seasonings, you can add them at this stage.
Add the dry corn muffin mix to the bowl containing the zucchini and onion.
Stir gently until the dry mix is distributed throughout the vegetables.
The corn muffin mix helps absorb some of the moisture from the zucchini and creates the tender cornbread-like texture of the finished casserole.
Avoid overmixing at this point. You only need to combine the ingredients evenly.
Pour the beaten eggs into the zucchini mixture.
Add the salt and ground black pepper.
Stir everything together until the eggs are evenly incorporated.
The eggs help bind the ingredients together as the casserole bakes and contribute to its tender, cohesive texture.
Make sure there are no large pockets of dry corn muffin mix remaining.
Add approximately half of the shredded cheddar cheese to the zucchini mixture.
Stir gently until the cheese is evenly distributed.
Saving the remaining cheese for the top gives the casserole a delicious melted and golden cheese layer.
For the best melting texture, freshly shredded cheddar works particularly well.
Lightly coat a suitable baking dish with cooking spray.
Make sure the bottom and sides are evenly coated to make serving easier after baking.
Transfer the zucchini mixture into the prepared dish.
Use a spatula or the back of a spoon to spread the mixture evenly.
Try to keep the surface relatively level so the casserole cooks uniformly.
Sprinkle the remaining shredded cheddar cheese evenly over the top of the casserole.
Make sure the cheese reaches close to the edges so you get a delicious golden, cheesy crust around the entire dish.
If you prefer an extra-cheesy casserole, you can reserve a little additional cheddar for the final few minutes of baking.
Place the casserole in the preheated oven.
Bake for approximately 40–50 minutes, or until the center is set and the top is golden brown.
The exact cooking time may vary depending on the size and depth of your baking dish and the amount of moisture in the zucchini.
The casserole should look firm in the center rather than loose or liquid.
If the cheese becomes golden before the center is fully cooked, loosely cover the casserole with aluminum foil and continue baking until it is set.
Remove the casserole from the oven and allow it to rest for approximately 5–10 minutes before serving.
This short resting period allows the casserole to finish setting and makes it easier to cut into neat portions.
Serve warm with your favorite main dish.
Fresh chopped parsley, green onions, or a sprinkle of black pepper can be added as a simple garnish.
Notes
The main thing to remember when making zucchini cornbread casserole is that zucchini naturally contains a lot of water.
Some zucchini is much more watery than others, especially very large garden-grown zucchini. If your shredded zucchini looks extremely wet, gently squeeze out some of the excess liquid before adding it to the recipe.
However, avoid squeezing every drop of moisture from the zucchini. The natural moisture helps create the soft, tender texture that makes this casserole so enjoyable.
The size of your baking dish also affects cooking time. A wider, shallower dish will generally cook faster than a smaller, deeper dish.
The casserole is ready when the center is set and no longer looks wet or loose. The edges should be lightly golden, and the cheese on top should be melted and browned.
If you notice that the cheese is browning too quickly, cover the top loosely with foil during the remaining cooking time.
For the best presentation, allow the casserole to rest for several minutes after removing it from the oven. Cutting it immediately can cause the center to appear softer and make the portions more difficult to serve.
Freshly shredded cheddar cheese generally melts better than pre-shredded cheese because packaged shredded cheese can contain anti-caking ingredients that affect melting.
