Description

Cheesy zucchini casserole melds garden-fresh vegetables with creamy, melted cheese in a comforting midwestern classic. Hearty layers of zucchini, cheese, and herbs create a satisfying dish you’ll crave at family gatherings and potlucks.


Ingredients

Scale
  • 1 cup shredded cheddar cheese
  • 1/2 cup grated Parmesan cheese
  • 4 medium zucchini, sliced
  • 2 large eggs
  • 1/2 cup breadcrumbs (panko preferred)
  • 1/2 cup sour cream
  • 2 tbsps melted butter
  • 1/4 cup chopped onion
  • 1 tsp garlic powder
  • Salt and pepper to taste

Instructions

  1. Preheat the oven to 375°F (190°C), creating an ideal environment for the casserole’s transformation.
  2. Generously coat a baking dish with cooking spray or butter to prevent sticking and ensure easy serving.
  3. Slice zucchini into uniform pieces to guarantee consistent cooking and texture throughout the dish.
  4. Whisk eggs in a spacious mixing bowl until smooth and light, creating a binding foundation for the casserole.
  5. Incorporate sour cream, chopped onion, garlic powder, salt, and pepper into the egg mixture, blending thoroughly to distribute flavors evenly.
  6. Fold in most of the cheddar and Parmesan cheeses, reserving a small portion for the crispy topping.
  7. Carefully transfer the zucchini mixture to the prepared baking dish, spreading it into an even layer to promote uniform cooking.
  8. Combine breadcrumbs with melted butter and the reserved cheese in a separate bowl, creating a golden, crunchy topping.
  9. Sprinkle the breadcrumb mixture generously over the zucchini base, ensuring complete coverage for maximum crispiness.
  10. Bake for 30-35 minutes, watching for a rich golden-brown color and bubbling edges that indicate perfect doneness.
  11. Allow the casserole to rest for 5 minutes after removing from the oven, which helps set the texture and makes serving easier.
  12. Serve warm, showcasing the dish’s creamy interior and crisp, cheesy topping.

Notes

  • Enhance the zucchini’s flavor by salting and draining it beforehand to remove excess moisture, preventing a soggy casserole.
  • Try different cheese varieties like Gruyère or mozzarella for unique flavor profiles and added depth.
  • Boost nutrition by incorporating additional vegetables like spinach or bell peppers into the base mixture.
  • For a gluten-free option, replace breadcrumbs with crushed almond flour or gluten-free crackers to maintain the crispy topping texture.
