  • Total Time: 1 hour 15 minutes
  • Yield: 8 servings

Ingredients

Main Ingredients

  • 2 large eggs, lightly beaten
  • ½ cup sour cream
  • ½ cup 2% plain Greek yogurt
  • 1 cup (4 oz.) shredded sharp cheddar cheese
  • 2 tablespoons grated Parmesan cheese
  • 1 teaspoon kosher salt
  • ½ teaspoon ground black pepper
  • ½ teaspoon garlic powder
  • ½ teaspoon Italian seasoning
  • 4 cups coarsely grated zucchini, lightly packed (about 1 ¼ pounds)
  • 2 cups cooked white rice (brown rice can be used)
  • ½ cup minced onion

Topping

  • ¼ cup panko bread crumbs
  • 2 tablespoons grated Parmesan cheese
  • ½ teaspoon Italian seasoning

Instructions

  1. Prepare Oven and Dish: Preheat your oven to 350°F (177°C). Lightly spray an 8 x 11 inch baking dish with nonstick cooking spray to prevent sticking and ensure easy cleanup.
  2. Mix Wet Ingredients and Spices: In a large mixing bowl, lightly beat the eggs. Stir in sour cream, Greek yogurt, shredded sharp cheddar cheese, grated Parmesan, kosher salt, black pepper, garlic powder, and Italian seasoning. Mix thoroughly until well combined to create a creamy base for the casserole.
  3. Combine Vegetables and Rice: Add the coarsely grated zucchini, cooked white rice, and minced onion to the bowl with the wet mixture. Stir gently but thoroughly to evenly incorporate all ingredients, ensuring a uniform texture in the casserole.
  4. Transfer to Baking Dish: Spread the combined mixture evenly into the prepared baking dish, smoothing the top to allow for even baking and browning.
  5. Prepare and Add Topping: In a small bowl, mix together panko bread crumbs, grated Parmesan cheese, and Italian seasoning. Sprinkle this evenly over the zucchini mixture to create a crispy, flavorful topping once baked.
  6. Bake the Casserole: Place the baking dish in the preheated oven and bake for 1 hour, or until the top is golden brown and the casserole is heated through. Testing doneness by gently pressing the center to ensure it is firm and set.

Notes

  • For a healthier option, substitute brown rice for white rice.
  • Make sure zucchini is only lightly packed to avoid excess moisture in the casserole.
  • Use freshly grated cheese for the best flavor and texture.
  • Let the casserole cool for 5-10 minutes before serving to allow it to set.
  • Store leftovers in an airtight container in the refrigerator for up to 3 days.
  • This casserole can be reheated in the oven or microwave.
