How to Make Zucchini Squash Casserole
Step 1: Prepare the Zucchini and Onion Base
Start by preheating your oven to 375°F. Then, spray a two-quart baking dish with cooking spray. In a skillet, melt butter over medium heat. Add the chopped onion and cook until translucent, about 5 minutes. Next, add the zucchini, cooking for an additional 4-5 minutes to reduce its moisture.
Step 2: Mix the Casserole Base
In a medium bowl, combine half of the stuffing mix, half of the cheddar cheese, eggs, milk, and the zucchini-onion mixture. Gradually add water until the mixture is moist, but not overly wet. Spread this base mixture evenly into your prepared baking dish.
Step 3: Assemble the Topping
In a small bowl, mix the remaining stuffing mix, cheddar cheese, and 3 tablespoons of butter. This topping adds a delightful crunch to your casserole. Sprinkle it evenly over the base in the baking dish.
Step 4: Bake to Golden Perfection

Bake your casserole for about 25 minutes, or until the topping is lightly browned. The aroma will fill your kitchen, making it hard to wait!
