Ingredients List for Baked Tuscan Chicken Casserole
To make this casserole, you’ll need the following ingredients, all of which contribute to the depth and richness of the dish:
- 4 boneless, skinless chicken breasts
- 1 tablespoon olive oil
- 2 teaspoons Italian seasoning
- Salt and pepper to taste
- 3 cloves garlic, minced
- ½ cup sun-dried tomatoes, chopped (preferably in oil, drained)
- 3 cups fresh baby spinach
- 1 cup heavy cream
- 1 cup chicken broth
- ½ cup grated Parmesan cheese
- ½ cup shredded mozzarella cheese
- 1 teaspoon red pepper flakes (optional for heat)
- 1 tablespoon fresh parsley, chopped (for garnish)
This ingredient list is designed to bring out that signature Tuscan flavor with a balance of creaminess, savory chicken, and rich, tangy tomatoes. You can also adjust the heat with red pepper flakes, depending on your preference.
Substitutions and Variations
While the base recipe for Baked Tuscan Chicken Casserole is already delicious, there are several ways you can modify it to suit your dietary needs or flavor preferences:
- Chicken: If you don’t have chicken breasts on hand, you can substitute them with boneless, skinless chicken thighs for an even juicier texture.
- Dairy-free Option: For those avoiding dairy, substitute the heavy cream with full-fat coconut milk and replace the cheeses with dairy-free alternatives.
- Vegetables: Feel free to add extra vegetables such as mushrooms or zucchini for a heartier dish. These veggies pair well with the cream sauce and can bulk up the casserole.
- Low-carb/Keto Variation: Replace the sun-dried tomatoes with roasted red peppers to reduce the carb count without sacrificing flavor.
- Herbs: Swap out parsley for basil or rosemary to give the dish a fresh and slightly different flavor profile.
Step-by-Step Cooking Instructions for Baked Tuscan Chicken Casserole

Cooking this casserole is simple, but following these steps ensures that your dish turns out perfectly golden and flavorful every time.
- Preheat Your Oven: Start by preheating your oven to 375°F (190°C). Grease a 9x13-inch baking dish with non-stick spray or a light layer of olive oil.
- Season the Chicken: Pat the chicken breasts dry with paper towels. Rub the chicken with olive oil, then sprinkle both sides with Italian seasoning, salt, and pepper.
- Sear the Chicken: Heat a large skillet over medium-high heat. Add a tablespoon of olive oil, then sear the chicken breasts for 3-4 minutes on each side, until they are golden brown but not fully cooked through. Remove the chicken and set aside.
- Make the Sauce: In the same skillet, lower the heat to medium and add the minced garlic. Sauté for 1 minute until fragrant, being careful not to burn the garlic. Add the chopped sun-dried tomatoes and spinach, stirring until the spinach wilts.
- Add Liquids: Pour in the chicken broth and heavy cream. Stir well, then bring the mixture to a simmer. Add Parmesan cheese and red pepper flakes (if using), and continue stirring until the sauce thickens slightly, about 3-4 minutes.
- Assemble the Casserole: Place the seared chicken breasts in your prepared baking dish. Pour the creamy tomato and spinach sauce over the chicken, ensuring each piece is well coated. Sprinkle the top with shredded mozzarella cheese.
- Bake: Place the dish in the preheated oven and bake for 20-25 minutes, or until the chicken is fully cooked and the cheese is bubbly and golden.
- Garnish and Serve: Remove from the oven and allow the casserole to rest for 5 minutes. Garnish with freshly chopped parsley before serving.
Common Mistakes to Avoid
- Overcooking the Chicken: The key to tender, juicy chicken is to avoid overcooking it. Since the chicken will finish cooking in the oven, sear it just until golden on the outside, leaving the inside slightly underdone.
- Not Thickening the Sauce: Ensure that your sauce has thickened slightly before adding it to the casserole. If the sauce is too runny, it could lead to a watery casserole.
- Skipping the Searing Step: Searing the chicken first locks in the moisture and adds depth of flavor. Don’t skip this step even if you’re tempted to save time.
- Using Low-fat Dairy: Full-fat ingredients like heavy cream and Parmesan provide the richness needed for the sauce. Using lower-fat alternatives could result in a thinner, less flavorful dish.
Serving and Presentation Tips for Baked Tuscan Chicken Casserole
This casserole is not only delicious but also visually appealing. When it comes to serving and presentation, here are some tips to elevate the meal:
