Ingredients

  • 1 lb boneless, skinless chicken breasts or thighs, cut into bite-sized pieces
  • 2 medium zucchini, sliced or chopped
  • 1 tbsp olive oil
  • 2 cloves garlic, minced
  • 1 small onion, diced
  • 1 cup shredded mozzarella cheese, divided
  • 1/4 cup grated Parmesan cheese
  • 1/2 cup sour cream or Greek yogurt
  • 1 tsp dried Italian seasoning
  • Salt, to taste
  • Black pepper, to taste

Instructions

  1. Preheat the oven to 375°F (190°C) and lightly grease a baking dish.
  2. Heat olive oil in a skillet over medium heat and sauté the onion and garlic until fragrant and translucent.
  3. Add the chicken pieces and cook until browned on all sides (not fully cooked through).
  4. In a large bowl, combine the sautéed chicken, zucchini, sour cream, half of the mozzarella, Parmesan, Italian seasoning, salt, and pepper.
  5. Transfer the mixture into the prepared baking dish and spread it evenly.
  6. Sprinkle the remaining mozzarella cheese over the top.
  7. Bake for 25–30 minutes until the chicken is cooked through, zucchini is tender, and cheese is bubbly and golden.
  8. Let it cool for a few minutes before serving.

Notes

  • Use cooked chicken to save time—skip the sautéing step and mix it directly into the dish.
  • Don’t peel the zucchini; the skin adds nutrients and texture.
  • Add other vegetables like mushrooms, spinach, or bell peppers for variety.
  • Greek yogurt is a great low-fat substitute for sour cream.
  • Try Monterey Jack or cheddar if you don’t have mozzarella or Parmesan.
