Step-by-Step Instructions
Step 1: Prepare the chicken
Preheat your oven to 375°F (190°C).
Grease a large baking dish with butter or cooking spray.
Cut chicken breasts into medium-sized bite-sized pieces.
Pat dry with paper towels.
Place the chicken in a large bowl.
Add olive oil, garlic powder, paprika, onion powder, Italian seasoning, black pepper, and salt.
Mix thoroughly until every piece is evenly coated.
Step 2: Brown the chicken
Heat a large skillet over medium-high heat.
Add a little olive oil.
Place the seasoned chicken pieces in the skillet in a single layer.
Sear for approximately 2–3 minutes per side until lightly golden.
The chicken does not need to be fully cooked at this stage.
Transfer to a plate.
Step 3: Cook the mushrooms
In the same skillet, melt butter over medium heat.
Add sliced mushrooms.
Cook for approximately 4–5 minutes until softened and lightly browned.
Add chopped onion and cook for another 2 minutes.
Stir in minced garlic and dried thyme.
Cook for 30 seconds until fragrant.
Step 4: Add the spinach
Add fresh spinach to the skillet.
Stir gently until the spinach wilts.
This usually takes 1–2 minutes.
Remove excess liquid if the vegetables release too much moisture.
Set aside.
Step 5: Prepare the creamy sauce
In a mixing bowl, combine softened cream cheese and heavy cream.
Whisk until smooth.
Add chicken broth, Parmesan cheese, Italian seasoning, black pepper, and a little salt.
Mix until the sauce becomes creamy and smooth.
Step 6: Assemble the casserole
Arrange the browned chicken pieces evenly in the prepared baking dish.
Spread the mushroom, onion, and spinach mixture over the chicken.
Pour the creamy sauce evenly over everything.
Use a spoon to distribute the sauce between the chicken pieces.
Step 7: Add the cheese
Sprinkle shredded mozzarella evenly over the casserole.
Add shredded cheddar and Parmesan cheese.
Make sure the chicken and vegetables are covered with a generous layer of cheese.
Step 8: Bake
Place the baking dish in the preheated oven.
Bake uncovered for approximately 25–35 minutes, depending on the size of the chicken pieces and how much they were cooked during browning.
The chicken must reach an internal temperature of 165°F (74°C).
The cheese should become melted, golden, and bubbly.
If needed, broil for 1–2 minutes at the end for a beautiful golden-brown topping. Watch carefully to prevent burning.
Step 9: Rest the casserole
Remove the dish from the oven.
Allow it to rest for 5–10 minutes.
This helps the creamy sauce settle and makes serving easier.
Step 10: Garnish and serve
Sprinkle freshly chopped parsley over the top.
Add a little extra Parmesan and black pepper if desired.
Serve warm while the cheese is still melted and stretchy.
