Ingredients
For the chicken
700 g boneless, skinless chicken breast or thighs, cut into bite-sized pieces
1 tablespoon olive oil
1 teaspoon paprika
1 teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon dried oregano or Italian seasoning
½ teaspoon salt, or to taste
¼ teaspoon black pepper
For the vegetables
2 medium zucchini, sliced
1 medium yellow squash, sliced
1½ cups broccoli florets
1 red bell pepper, chopped
1 yellow bell pepper, chopped
½ small onion, chopped (optional)
For the cheesy topping
1½ cups shredded mozzarella cheese (about 150 g)
½ cup grated Parmesan cheese (about 45–50 g)
2 tablespoons cooking cream (optional)
1 teaspoon minced garlic
1 teaspoon Italian seasoning
1 tablespoon fresh parsley, chopped
Instructions
Step 1: Preheat the oven
Preheat your oven to 200°C (400°F). Lightly grease a 9 × 13-inch baking dish with olive oil.
Step 2: Season the chicken
Place the chicken pieces in a large bowl. Add olive oil, paprika, garlic powder, onion powder, oregano, salt, and black pepper. Mix thoroughly until the chicken is evenly coated.
Step 3: Prepare the vegetables
Wash and dry all the vegetables. Slice the zucchini and yellow squash into thick half-moons. Chop the bell peppers and cut the broccoli into small florets.
Step 4: Assemble the casserole
Arrange the seasoned chicken and vegetables in the prepared baking dish. Add the minced garlic and Italian seasoning, then toss gently to distribute the seasonings evenly.
If you prefer a creamier casserole, drizzle the cooking cream over the mixture.
Step 5: Bake
Bake uncovered for 20–25 minutes. Cooking time will depend on the size of the chicken pieces and your oven. If the vegetables release too much liquid, carefully drain the excess before adding the cheese.
Step 6: Add the cheese
Sprinkle the mozzarella evenly over the chicken and vegetables. Add the Parmesan cheese on top.
Return the dish to the oven for another 8–12 minutes, until the cheese melts, bubbles, and becomes golden brown.
Step 7: Finish and serve
For a deeper golden crust, broil for 1–3 minutes, watching carefully to prevent burning.
Check that the thickest chicken pieces reach an internal temperature of 74°C (165°F). Let the casserole rest for 5 minutes, sprinkle with fresh parsley, and serve warm.

Frequently Asked Questions
1. Can I make this without cream?
Yes. The cream is optional. The melted mozzarella and Parmesan provide plenty of richness.
2. Can I use chicken thighs?
Yes. Boneless, skinless thighs are juicy and flavorful. Cook until the internal temperature reaches 74°C (165°F).
3. Why is my casserole watery?
Zucchini and squash naturally release water. Dry the vegetables thoroughly, avoid overcrowding the baking dish, and drain excess liquid before adding the cheese.
4. Can I prepare it ahead of time?
Yes. Chop the vegetables and season the chicken separately, then refrigerate in covered containers. Assemble before baking for the best texture.
5. How do I store leftovers?
Refrigerate within two hours in an airtight container and consume within 3–4 days. Reheat to 74°C (165°F). Freeze for approximately 2–3 months for best quality.
6. Can I use frozen vegetables?
Yes. Thaw and drain them thoroughly before baking. The texture may be softer than with fresh vegetables.
7. What can I serve with this dish?
Serve with steamed rice, roasted potatoes, garlic bread, or a fresh green salad. For a low-carb meal, enjoy it on its own.
8. How can I make it spicy?
Add ¼–½ teaspoon chili flakes, cayenne pepper, or chopped green chili to the chicken seasoning.
9. Which cheese works best?
Mozzarella gives the stretchy, melted topping, while Parmesan adds a salty, savory flavor. Freshly shredded mozzarella usually melts more smoothly.
10. How do I get a golden, bubbly topping?
Add the cheese during the final 8–12 minutes of baking. Finish under the broiler for 1–3 minutes, keeping a close eye on it.
Best Tips for Success
Cut the chicken into evenly sized pieces.
