Ingredients

Scale

Protein and Vegetables

  • 1 lb (454 g) skinless, boneless chicken breast
  • 3 small or 2 medium zucchini, sliced (about 3 cups / 360 g)
  • 1 cup (30 g) fresh spinach
  • 1 cup (150 g) cherry or grape tomatoes, halved
  • ½ cup (65 g) sun-dried tomatoes in oil, chopped
  • 1 shallot, thinly sliced
  • 2 cloves garlic, minced

Seasonings and Oils

  • 1 tbsp (15 ml) olive oil
  • 1 tsp (1 g) dried oregano leaves
  • 1 tsp (1 g) dried basil leaves
  • 1 tsp (3 g) garlic powder
  • 1 tsp (5 g) salt
  • ½ tsp (1 g) black pepper
  • ½ tsp (1 g) paprika
  • ¼ tsp (0.5 g) red pepper flakes

Cheeses and Garnish

  • 1 cup (113 g) shredded mozzarella cheese
  • ½ cup (50 g) grated Parmesan cheese
  • ⅛ cup (5 g) chopped fresh parsley for garnish

Instructions

  1. Preheat the Oven: Preheat your oven to 375°F (190°C) to ensure it reaches the right temperature for baking the casserole evenly.
  2. Combine Ingredients: In a 2.5-quart (11×7-inch / 28×18 cm) baking dish, add the chicken breast, sliced zucchini, fresh spinach, halved cherry or grape tomatoes, chopped sun-dried tomatoes, thinly sliced shallot, minced garlic, and olive oil. Sprinkle the dried oregano, dried basil, garlic powder, salt, black pepper, paprika, and red pepper flakes over the mixture.
  3. Toss to Coat: Gently toss all ingredients together in the baking dish to ensure everything is evenly coated with the herbs, spices, and olive oil.
  4. Add Cheese: Evenly sprinkle the shredded mozzarella and grated Parmesan cheese on top of the vegetable and chicken mixture.
  5. Cover and Bake: Cover the dish tightly with aluminum foil and bake in the preheated oven for 20 minutes. This allows the chicken to cook through and the vegetables to soften.
  6. Remove Foil and Continue Baking: Remove the foil and bake uncovered for an additional 10 minutes to let the cheese start to brown and the top to set.
  7. Broil for Golden Cheese: Switch the oven to broil on high and broil the casserole for 1 to 2 minutes. Keep a close eye and check every 20 seconds to prevent burning, allowing the cheese to develop a golden crust.
  8. Garnish and Serve: Sprinkle chopped fresh parsley over the top before serving. Optionally, add a pinch of oregano, black pepper, and red pepper flakes for extra seasoning according to your taste preference.

Notes

  • You can substitute chicken thighs for chicken breast if you prefer a juicier texture.
  • Sun-dried tomatoes packed in oil add depth of flavor; if using dry-packed, rehydrate them in hot water before use.
  • For a lower-fat version, reduce the amount of cheese or use part-skim mozzarella.
  • Ensure to watch closely when broiling to avoid burning the cheese topping.
  • This casserole can be prepared a day ahead and baked just before serving for convenience.
