How to Make Baked Tuscan Chicken Casserole
-
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with a little olive oil or cooking spray to ensure nothing sticks during baking.
-
Heat olive oil in a skillet over medium heat. Season your chicken breasts with salt, pepper, and Italian seasoning. Sear them for 3-4 minutes per side until they’re golden brown and fully cooked.
-
Transfer the seared chicken into your greased baking dish. This acts as the hearty base of your delicious casserole.
-
Sauté onions in the same skillet until they soften, about 3 minutes. Add minced garlic and sauté for an additional minute, then toss in sun-dried tomatoes and spinach. Cook until the spinach wilts.
-
Whisk together heavy cream, chicken broth, Parmesan, mozzarella, and cream cheese in a large bowl until smooth. Then, pour this luscious sauce over the chicken in the baking dish.
-
Top with the sautéed veggies you prepared earlier, and sprinkle the remaining cheese on top for an extra layer of flavor.
-
Bake for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F and the casserole is bubbly and golden.
-
Let rest for 5 minutes after removing from the oven. This resting time allows the flavors to meld beautifully before you dig in!

Expert Tips for Baked Tuscan Chicken Casserole
-
Juicier Chicken: Consider using thighs instead of breasts for a more succulent result in your Baked Tuscan Chicken Casserole. Thighs tend to have more moisture!
-
Resting Time: Allow the casserole to rest for at least 5 minutes after baking to let the flavors blend and prevent a saucy mess when serving.
-
Check Chicken Doneness: Ensure your chicken is seared but not fully cooked before baking to avoid dryness; it will finish cooking in the oven.
-
Prevent Over-Browning: If the top of your casserole begins to brown too quickly, cover it loosely with aluminum foil to protect the cheese and keep it gooey.
-
Customize Ingredients: Don’t hesitate to swap veggies or proteins based on your family’s preferences, making this recipe versatile for everyone.

Baked Tuscan Chicken Casserole Recipe FAQs
What type of chicken should I use for this casserole?
I recommend using chicken breasts for a lean protein option, but chicken thighs can be a wonderful alternative for juicer results. Thighs will remain tender and less likely to dry out during baking, making your Baked Tuscan Chicken Casserole even more satisfying!
How can I store leftovers of the casserole?
Absolutely! Leftovers can be stored in an airtight container in the fridge for up to 3-4 days. When you’re ready to enjoy, I suggest reheating it in the oven for a few minutes to keep the texture intact, or microwaving it until warmed through.
Can I freeze this casserole?
Yes, you can freeze your Baked Tuscan Chicken Casserole! To do this, wrap the unbaked casserole tightly in plastic wrap and then foil, ensuring it’s well-sealed to prevent freezer burn. It can be frozen for up to 3 months. When you’re ready to bake, simply thaw it overnight in the fridge, then pop it in the oven.
What should I do if the casserole seems too saucy after baking?
If your casserole appears too saucy, don’t worry! Next time, you might reduce the amount of heavy cream or increase the baking time slightly. Be sure to let it rest after baking, as this will give it a chance to set. It’s all about finding that delightful balance!
Are there any dietary considerations for this recipe?
Definitely! This casserole is naturally gluten-free, making it a great choice for those on gluten-free diets. If you have dairy allergies, consider using dairy-free cream and cheese alternatives. Always double-check labels to ensure all your substitutions fit your dietary needs.
How do I know when the chicken is fully cooked?
To ensure your chicken is cooked through, aim for an internal temperature of 165°F (74°C). Using a meat thermometer is the best way to check; you can insert it into the thickest part of the chicken breasts. It’s essential to ensure safety while still keeping the chicken juicy in your Baked Tuscan Chicken Casserole!
