Chicken Zucchini Casserole is a hearty, cheesy, and veggie-packed comfort dish made with tender chicken, sautéed zucchini, and a creamy, savory sauce. Topped with golden cheese and breadcrumbs, it’s a satisfying, wholesome meal perfect for family dinners or meal prep.

Ingredients

  • 2–3 cups cooked chicken breast or thighs, shredded or diced
  • 2 medium zucchini, sliced or diced
  • 1 small onion, chopped
  • 2 cloves garlic, minced
  • ½ cup sour cream or plain Greek yogurt
  • ¼ cup mayonnaise
  • 1½ cups shredded cheddar cheese (divided)
  • ¼ cup grated Parmesan cheese (optional)
  • 1 egg
  • 1 teaspoon Italian seasoning
  • Salt and pepper, to taste
  • 1 tablespoon olive oil or butter (for sautéing)
  • ½ cup breadcrumbs or crushed crackers (for topping)

Instructions

  1. Preheat oven to 375°F (190°C) and grease a casserole dish.
  2. Heat oil or butter in a skillet. Sauté onion and garlic until softened, then add zucchini and cook for 3–4 minutes until slightly tender.
  3. In a large bowl, mix chicken, sautéed vegetables, sour cream, mayonnaise, egg, ¾ cup cheddar, Parmesan (if using), Italian seasoning, salt, and pepper.
  4. Spread the mixture evenly into the prepared casserole dish.
  5. Top with remaining cheddar cheese and breadcrumbs or crushed crackers.
  6. Bake for 30–35 minutes until hot, bubbly, and golden on top.
  7. Let rest for 5–10 minutes before serving.

Notes

  • Add cooked rice or quinoa to make it more filling.
  • Stir in spinach or kale for added greens.
  • Swap cheddar with mozzarella or pepper jack for variation.
  • Use cream of chicken soup instead of sour cream for a shortcut.
  • Substitute with gluten-free breadcrumbs if needed.
