Essential Ingredients for Zucchini Cornbread Casserole
Gathering these simple items gets you a delicious zucchini cornbread casserole with fresh corn flavor. Focus on fresh block cheese shredded by hand for better melt, and any plain milk works fine. Heres the exact list you need:
- 1 large zucchini (about half a pound)
- 1/2 teaspoon salt
- 1/4 medium onion
- 4 ounces of shredded cheddar cheese (block cheese shredded by hand)
- 1 box (8 ounces) of corn muffin mix
- 1 large egg
- 1/3 cup of milk (any plain milk)
The zucchini adds subtle freshness and moisture once drained. Dice that onion small for even bites, and shred the cheese yourself, reserving about one-third for the golden top. The corn muffin mix handles the cornbread base effortlessly.
Special Dietary Options
Make it your own with tweaks:
- Vegan: Use a flax egg (1 tbsp ground flax + 3 tbsp water) instead of the egg, plant-based milk, and vegan cheese or skip it.
- Gluten-free: Pick a gluten-free corn muffin mix.
- Low-calorie: Cut cheese to 3 ounces or use low-fat cheddar, and low-fat milk.
These changes keep the cornbread casserole tasty and inclusive for newlyweds hosting mixed diets or party hosts.
How to Prepare the Perfect Zucchini Cornbread Casserole: Step-by-Step Guide
Ready to make this cornbread casserole? Follow these steps for foolproof results. Total time is about 1 hour, yielding 16 pieces.
- Grate the 1 large zucchini directly into a colander. Sprinkle with 1/2 teaspoon salt and let it sit for at least 30 minutes to draw out moisture.
- Squeeze out the excess water thoroughly using your hands or a clean towel. This step avoids sogginess.
- Preheat the oven to 400°F. Dice the 1/4 medium onion finely.
- Shred the 4 ounces of cheddar cheese by hand from a block, reserving about one-third for topping.
- In a bowl, combine the squeezed zucchini, diced onion, two-thirds of the cheddar cheese, 1 box (8 ounces) corn muffin mix, 1 large egg, and 1/3 cup milk.
- Stir gently without overmixing to keep the texture light.
- Pour the mixture into an 8×8-inch baking pan. Sprinkle the remaining cheese on top.

For the best texture, grate and salt the zucchini the night before. Refrigerate after squeezing, then squeeze again before baking.
Quick Tips During Prep
