Cheesy Zucchini Casserole

Cheesy Zucchini Casserole combines diced, microwaved zucchini with a creamy blend of mayonnaise, sharp cheddar, egg, and seasonings, topped with a crunchy mixture of cracker crumbs, panko, cheese, and butter. Baking melds the flavors while giving the topping a golden, crisp texture. This casserole provides a rich, satisfying side dish highlighting zucchini’s moisture balanced with a crisp topping, suitable for family meals or potlucks.

Description

Cheesy Zucchini Casserole uses diced zucchini that is quickly microwaved to soften and drain excess moisture. The zucchini is then folded into a creamy mixture of mayonnaise, shredded sharp cheddar cheese, an egg, garlic powder, black pepper, and a bit of flour to bind everything. A crunchy topping made from cracker crumbs, panko, shredded cheddar, and melted butter is spread evenly on top before baking.

The casserole bakes at 350°F until bubbling and the topping turns golden brown, resulting in a warm, creamy interior complemented by a crisp, buttery crust. The sharp cheddar adds a tangy richness, while the garlic powder and pepper offer mild savory notes.

This dish serves well as a comforting side alongside roasted meats or on its own for a light vegetarian option. It can be served hot straight from the oven to retain the topping’s texture. The balance between the tender zucchini and crunchy topping makes it appealing for a variety of meals where a creamy vegetable side is desired.

The recipe benefits from microwaving zucchini to reduce water content, preventing a soggy casserole. Using mayonnaise instead of Miracle Whip maintains a richer flavor. Letting the topping mixture coat evenly ensures a consistent crispness across the surface.

Ingredients

Servings
  • 2 large zucchini trimmed and cut into 1 inch dice (this will be about 4-5 cups)
  • 1 cup mayonnaise (not Miracle Whip)
  • 1 cup cheddar cheese white or yellow, shredded sharp
  • 1 extra large egg
  • 1 Tbsp flour
  • 1 tsp black pepper fresh cracked
  • 1 tsp garlic powder

crunchy topping

  • 1/4 cup cracker crumbs Ritz
  • 2 Tbsp panko bread crumbs
  • 2 Tbsp cheddar cheese sharp, shredded
  • 2 Tbsp butter melted

Instructions

  1. Preheat the oven to 350°F. Butter a 1 1/2 quart gratin or casserole dish.
  2. Put the diced zucchini in a large microwave safe bowl and microwave on high for about 4-5 minutes, stirring to rearrange the zucchini twice during cooking. Drain the zucchini in a mesh strainer to remove any excess moisture and set aside.
  3. Toss the topping ingredients together in a small bowl, mixing until the butter is evenly dispersed and everything is evenly mixed. Set aside.
  4. Whisk together the remaining casserole ingredients to combine well.
  5. Fold in the zucchini and turn into your prepared casserole dish.
  6. Sprinkle the topping evenly over the casserole and bake for about 45 minutes, or until the casserole is bubbling and the topping is golden. Serve immediately.

Notes

  • Microwaving the diced zucchini before assembling helps remove excess moisture, which prevents the casserole from becoming watery.
  • Use mayonnaise, not Miracle Whip, to maintain the intended flavor and texture.
  • The topping should be evenly mixed and spread for a uniform crunchy crust.
  • Serve immediately to enjoy the contrast between creamy interior and crispy topping.
