Ingredients

Scale

Zucchini Mixture

  • 4 cups Zucchini, diced into 1 inch pieces
  • 1 cup Mayonnaise
  • 1 cup Shredded Cheddar Cheese
  • 2 Eggs, slightly beaten
  • 1 tsp Pepper
  • 3/41 tsp Garlic Powder

Topping

  • 1/4 cup Panko Breadcrumbs
  • 1 Tbsp Butter, melted

Instructions

  1. Parboil the Zucchini: Bring a pot of water to a boil and add the diced zucchini. Cook for 3 minutes until slightly tender but not fully cooked. Drain and allow to cool completely to prevent excess moisture in the casserole.
  2. Combine the Mixture: In a large bowl, mix the cooled parboiled zucchini with mayonnaise, shredded cheddar cheese, beaten eggs, pepper, and garlic powder until well incorporated.
  3. Prepare the Baking Dish: Grease a 1 1/2 quart baking dish to prevent sticking, then pour in the zucchini mixture, spreading it evenly.
  4. Make the Topping: In a small bowl, combine the Panko breadcrumbs with melted butter. Sprinkle this mixture evenly over the top of the casserole for a crispy, golden crust.
  5. Bake the Casserole: Place the dish in a preheated oven at 350°F (175°C) and bake uncovered for 35 minutes, or until the zucchini is fork tender and the topping is golden brown.

Notes

  • Do not overcook the zucchini when boiling to avoid soggy casserole.
  • Use full-fat mayonnaise and cheese for creamier texture.
  • Panko breadcrumbs can be substituted with regular breadcrumbs if needed, but Panko adds extra crunch.
  • Allow the casserole to rest for 5 minutes after baking for easier serving.
  • For added flavor, consider adding some chopped onions or herbs like parsley.
