Ingredient Notes & Details

Zucchini

Grate it finely and lightly squeeze excess water to avoid sogginess.

Cornbread mix
A standard boxed mix keeps this recipe quick and reliable.
You can use homemade cornbread mix if preferred.

Eggs
Help bind the casserole and add structure.
Room-temperature eggs mix more evenly.

Butter
Adds richness and flavor.
Melted butter gives the best texture.

Sour cream
Keeps the casserole extra moist and tender.
Greek yogurt is a great substitute.

Cheddar cheese
Creates a cheesy, savory finish.
Sharp cheddar adds the most flavor.

Salt and black pepper
Enhances all the flavors.
Season lightly and adjust to taste.

Add the cornbread mix
