How to Make Baked Tuscan Chicken Casserole

Getting this casserole ready is a breeze! Here’s a step-by-step guide to show you how it all comes together:

  1. Preheat your oven to 400°F (200°C) to create that perfect baking environment.
  2. Prepare your chicken by halving the breasts and seasoning them generously with salt, pepper, and garlic powder. Arrange them in a greased baking dish to ensure they don’t stick.
  3. In a separate mixing bowl, combine the softened cream cheese and heavy cream, beating together until you achieve a smooth consistency. This creamy base is essential for the richness of the casserole.
  4. Add in the onion powder, paprika, Italian seasoning, grated Parmesan, and half of the mozzarella to your cream mixture, stirring well.
  5. Evenly pour the creamy mixture over the seasoned chicken in your baking dish.
  6. Drizzle the oil from the sun-dried tomato jar over the dish for an extra layer of flavor, then scatter the chopped sun-dried tomatoes throughout for those delicious bites.
  7. Cover the baking dish with foil and bake for 20 minutes to allow the chicken to cook through gently.
  8. After 20 minutes, remove the foil, add your chopped spinach, and sprinkle the remaining mozzarella on top. Bake uncovered for another 10 minutes until the cheese is bubbly and melted.

Frequently Asked Questions

Can I use frozen spinach instead of fresh?

Absolutely! Just ensure to thaw and squeeze out as much water as possible so it doesn’t water down the sauce.

How do I store leftovers?

Leftovers can be placed in an airtight container in the fridge for up to three days. Simply reheat gently to preserve the creamy texture.

Can I make it ahead?

Yes! You can assemble the casserole ahead of time and refrigerate it. Bake as directed, adding an extra 5–10 minutes if it’s cold from the fridge.

Can I substitute the chicken?

For a twist, you can use turkey breast or even a plant-based protein if you’re looking for a meat-free version, keeping seasoning in mind to ensure flavor parity.

Is it okay to double the recipe?

Definitely! Just ensure your baking dish is large enough. Adjust the baking time accordingly; it may require an extra 10-15 minutes due to the increased volume.
