Step 1 — Prepare the chicken

Preheat your oven to 200°C (400°F), or 180°C fan.

Cut the chicken into large bite-sized pieces, or leave small chicken breasts whole.

Pat dry and season with paprika, garlic powder, salt, and black pepper.

Heat olive oil in a large skillet. Sear the chicken for 2–3 minutes per side until lightly golden. It does not need to be cooked through yet.

Step 2 — Cook the mushrooms

In the same skillet, add butter or olive oil.

Add sliced mushrooms and cook for 5–7 minutes.

Let their moisture evaporate so they brown instead of steam.

Add chopped onion if using, then minced garlic. Cook for another 1 minute.

Step 3 — Add the spinach

Season lightly with salt and pepper.

Taste and adjust the salt and pepper.

Step 5 — Assemble the casserole

Lightly grease a baking dish approximately 23 × 33 cm (9 × 13 inches).

Arrange the seared chicken evenly throughout the dish.

Spoon sauce over the chicken.

Sprinkle mozzarella evenly over the top, followed by extra Parmesan if desired.

Step 6 — Bake until golden

Bake uncovered for 20–30 minutes, depending on the size of the chicken pieces.

Check the thickest piece of chicken with a food thermometer. It must reach 74°C (165°F) internally.

For a more deeply browned cheese topping, broil for 1–3 minutes at the end, watching carefully.

Rest for 5–10 minutes before serving.

Garnish with parsley and serve hot.

6. Frequently asked questions (Q&A)
Q1. Can I use chicken thighs instead of chicken breasts?

Yes. Boneless, skinless thighs are juicier and more forgiving if slightly overcooked. Check that they reach an internal temperature of 74°C (165°F).

Q2. Can I use frozen spinach?

Yes. Thaw it and squeeze out as much water as possible before adding it to the sauce. Excess water can make the casserole thin.

Q3. Can I make it without heavy cream?

You can use cooking cream or evaporated milk with a little extra cream cheese. The sauce may be less rich. Avoid boiling milk-based substitutes, as they can split.

Q4. Why is my casserole watery?

The mushrooms or spinach likely retained too much moisture. Sauté mushrooms until browned and drain frozen spinach thoroughly. Also avoid adding too much broth.

Q5. Can I prepare it ahead of time?

Yes. Cook the vegetables and sauce, assemble with the seared chicken, cover, and refrigerate promptly. For best quality, bake within 24 hours. Because the ingredients start cold, baking may take longer; always check the chicken’s internal temperature.

Q6. How should I store leftovers?

Refrigerate within 2 hours in airtight containers and use within 3–4 days. Reheat until the center reaches 74°C (165°F). Freeze for up to 2–3 months for best quality, although the creamy sauce may change texture after thawing.

Q7. What can I serve with this dish?

Try garlic bread, rice, mashed potatoes, pasta, roasted potatoes, or a fresh green salad. For a lower-carbohydrate meal, serve with roasted broccoli, cauliflower rice, or zucchini noodles.

Q8. Can I make the cheese extra golden?

Use low-moisture mozzarella and finish under the broiler for 1–3 minutes. Stay beside the oven because cheese can burn quickly.

Q9. Can I make it without mushrooms?

Yes. Add extra spinach, sliced zucchini, or bell peppers. Cook watery vegetables first so they do not dilute the sauce.

Q10. How do I know when the chicken is done?

Use a food thermometer inserted into the thickest part. Poultry should reach 74°C (165°F). Color alone is not a reliable indicator.

For the best presentation, serve each portion with plenty of spinach and creamy sauce, making sure every piece gets some golden cheese and browned mushrooms. A sprinkle of parsley and freshly cracked black pepper finishes the dish beautifully.

Final tip: The key to recreating the photograph is a thick garlic-Parmesan cream sauce, well-drained spinach, browned mushrooms, evenly distributed chicken, and a generous layer of mozzarella baked until bubbly and golden.
