Step‑by‑Step Instructions for Baked Tuscan Chicken Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400ºF (200ºC). This ensures that your Baked Tuscan Chicken Casserole cooks evenly, resulting in a golden, bubbly cheese topping. While the oven heats, gather your ingredients and prepare your baking dish, so you’re ready to assemble as soon as the oven reaches the desired temperature.
Step 2: Prepare the Chicken
Take your boneless skinless chicken breasts and flatten them slightly using a meat mallet for even cooking. Arrange the chicken in a baking dish and season generously with salt, pepper, and half of the minced garlic. This layering of seasoning will give the chicken a wonderful flavor foundation, making the casserole truly delightful.
Step 3: Make the Creamy Sauce
In a large mixing bowl, combine the frozen chopped spinach, cream cheese, and heavy cream. Use a whisk or spatula to blend everything smoothly, incorporating the remaining garlic along with the onion powder, chili powder, black pepper, and Italian seasoning. Fold in the parmesan cheese and half of the mozzarella for a rich, creamy sauce that will envelop the chicken beautifully.
Step 4: Assemble the Casserole
Spread the luscious spinach and cream mixture evenly over the prepared chicken in the baking dish. Next, scatter the sun-dried tomatoes across the top, adding a touch of sweetness that complements the creaminess. Drizzle olive oil from the tomatoes over everything, then layer the remaining mozzarella cheese generously to create that gooey topping we all love.
Step 5: Bake to Perfection
Place the assembled casserole in your preheated oven and cover it with aluminum foil. Bake for 20 minutes to allow the chicken to cook through. After this initial baking time, remove the foil and continue baking for an additional 15 minutes, or until the chicken reaches an internal temperature of 165°F (71°C) and the cheese is bubbling and golden.
Step 6: Rest and Serve
Once baked, remove the casserole from the oven and let it rest for 5-10 minutes; this helps the flavors meld together and makes serving easier. Garnish with freshly chopped parsley for a pop of color and freshness. Serve your delicious Baked Tuscan Chicken Casserole alongside sides like cauliflower rice or zucchini noodles for a complete meal.

Baked Tuscan Chicken Casserole Recipe FAQs
How do I choose the best chicken for this casserole?
Absolutely! When selecting chicken, look for boneless skinless breasts that are pink and firm. Avoid any chicken with dark spots or a foul smell; these are signs of spoilage. Thinly slicing the chicken will help it cook evenly and stay tender within the creamy sauce.
What is the best way to store leftovers?
You can store any leftover Baked Tuscan Chicken Casserole in an airtight container in the refrigerator for up to 3 days. Let it cool completely before sealing to maintain its delicious flavors. If you’d like to enjoy it later, I recommend freezing it!

What should I do if the casserole is too watery?
If you find your casserole is too watery, this is often due to excess moisture in the spinach. Make sure to squeeze out as much liquid as possible before mixing it into the creamy filling. Additionally, letting the casserole rest for 5-10 minutes after baking helps it set, making it easier to serve without excess liquid.
Are there any dietary considerations I should know about?
