How to Make It

Follow these simple steps to create the casserole.

Grate the zucchini

Grate about 4 medium zucchinis using a box grater or food processor. Place grated zucchini in a large bowl and sprinkle with 1 teaspoon salt. Toss and let sit for 10 minutes to draw out excess water.

Squeeze out excess moisture

Using a clean kitchen towel or cheesecloth, squeeze out as much moisture as possible from the zucchini.

Combine the ingredients

In the same large bowl, combine the drained zucchini with 2 cups shredded sharp cheddar cheese, 4 ounces softened cream cheese, 1/2 cup mayonnaise, 1 teaspoon onion powder, 1/2 teaspoon garlic powder, and freshly ground black pepper to taste. Stir until well incorporated.

Prepare the topping

In a small bowl, mix 1 1/2 cups crushed Ritz crackers with 4 tablespoons melted unsalted butter until evenly coated.

Preheat the oven

Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.

Assemble the casserole

Spread the zucchini mixture evenly in the baking dish and smooth the top. Sprinkle the buttery Ritz cracker topping evenly over the zucchini layer.

Bake the casserole

Bake for 30-35 minutes until the top is golden brown and crispy and the casserole is bubbling at the edges.

Cool before serving

Let the casserole cool for 5-10 minutes before serving.

How to Store It
