  • 2 medium zucchinis, chopped into bite-sized pieces
  • 1 red bell pepper, diced

Cheese and Dairy:

  • 1 cup shredded mozzarella cheese

  • ½ cup sour cream

Seasonings and Topping:

  • ½ teaspoon garlic powder
  • ½ teaspoon dried thyme
  • 1 cup seasoned breadcrumbs
  • Salt

Instructions

  1. Preheat your oven to 375°F and coat a 9×13 inch baking dish with cooking spray, ensuring every inch is covered.
  2. Whisk 1 can cream of chicken soup, ½ cup sour cream, ½ teaspoon garlic powder, ½ teaspoon dried thyme, salt, and pepper in a large mixing bowl until smooth.
  3. Fold 2 chopped zucchinis, 1 diced red bell pepper, 2 cups cooked chicken, and ½ cup mozzarella cheese into the creamy mixture, stirring gently to combine.
  4. Spread the entire mixture evenly across the prepared baking dish, creating a smooth surface.
  5. Combine 1 cup seasoned breadcrumbs with 2 tablespoons melted butter in a small bowl, mixing until crumbs are completely coated.
  6. Sprinkle the buttered breadcrumbs across the casserole, then top with remaining ½ cup mozzarella and ½ cup Parmesan cheese.
  7. Bake at 375°F for 30-35 minutes until the top turns golden brown and the edges become bubbly.
  8. Remove from oven and let the casserole rest for 5 minutes before serving to allow flavors to settle.

Notes

  • Use fresh zucchini for the best texture and flavor in your casserole.
  • If watching carbs, swap breadcrumbs with crushed pork rinds or almond flour for a lower-carb version.
  • For a gluten-free option, use gluten-free cream of chicken soup and breadcrumbs.
  • Shredded rotisserie chicken works perfectly and saves time when preparing this dish.
