How to Make Baked Tuscan Chicken Casserole Recipe
Step 1: Prepare the Oven and Chicken
Begin by preheating your oven to 375°F (190°C). This ensures it’s ready for baking as soon as you finish prepping. Pat the chicken breasts dry, then season them evenly with garlic powder, onion powder, dried oregano, salt, and pepper. These spices form a simple but flavorful crust that complements the creamy sauce perfectly.
Step 2: Sear the Chicken
Heat olive oil in a large skillet over medium heat. Once hot, add the seasoned chicken breasts and sear them for about 3-4 minutes on each side. You’re aiming for a golden-brown exterior that locks in juicy flavors. After searing, remove the chicken from the skillet and set it aside – don’t worry, the best flavors are just getting started!
Step 3: Cook the Vegetables and Make the Sauce
In the same skillet (with that lovely chicken flavor), toss in the chopped sun-dried tomatoes and fresh spinach. Cook them for 2-3 minutes, just until the spinach wilts and the tomatoes release their sweet tang. Then, pour in the heavy cream and sprinkle in the Parmesan cheese. Stir continuously until the sauce thickens slightly, creating a luscious, cheesy coating that will cling beautifully to the chicken.
Step 4: Assemble and Bake
Arrange the seared chicken breasts in a baking dish in a single layer. Pour the creamy tomato-spinach sauce evenly over the chicken, making sure each piece is generously covered. Finish by sprinkling shredded mozzarella cheese on top. Slide the dish into the preheated oven and bake for 25-30 minutes, until the chicken is completely cooked through and the cheese is melted and bubbly, creating that irresistible golden crust.
Step 5: Garnish and Serve
Once out of the oven, sprinkle the freshly chopped basil over the casserole. This final step lifts the rich flavors, adding a touch of brightness and an inviting aroma that’s pure Tuscan magic. Now it’s time to dig in and savor every bite of your homemade Baked Tuscan Chicken Casserole Recipe!
How to Serve Baked Tuscan Chicken Casserole Recipe

Garnishes
Beyond fresh basil, consider adding a sprinkle of extra Parmesan or a drizzle of good quality olive oil right before serving. These finishing touches bring extra layers of flavor and texture, making the dish look as beautiful as it tastes.
Side Dishes
This casserole pairs wonderfully with a simple arugula salad tossed with lemon vinaigrette for a peppery crunch or roasted garlic potatoes for a comforting, hearty side. Steamed asparagus or garlic bread also complement the creamy richness perfectly, balancing out the meal.
Creative Ways to Present
For a cozy dinner, serve the casserole family-style right from the baking dish, inviting everyone to help themselves. If you want to impress, plate individual servings with a fresh basil sprig and a few sun-dried tomatoes on the side. Offering crusty bread or a light white wine to accompany the dish elevates the experience even more.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftovers into an airtight container and store in the refrigerator. This casserole keeps well for about 3-4 days, making it a fantastic option for quick meals later in the week.
Freezing
You can freeze this dish, but it’s best to do so before baking. Assemble the casserole, cover it tightly with foil, and freeze for up to 2 months. When ready to enjoy, thaw overnight in the fridge and then bake as directed.
Reheating
Reheat leftovers gently in the oven at 350°F until warmed through to preserve the rich, creamy sauce and prevent the chicken from drying out. Alternatively, use a microwave on medium heat, stirring the sauce occasionally, but the oven will give you the best results.
FAQs
Can I use chicken thighs instead of chicken breasts?
Absolutely! Chicken thighs stay juicy and flavorful and will work beautifully in this recipe. Just adjust baking time slightly to ensure they’re cooked through.
Is there a dairy-free version of this dish?
You can substitute heavy cream with coconut cream and use dairy-free cheese alternatives. While the flavor profile changes, it still produces a creamy and tasty casserole.
Can I make this dish vegetarian?
To make a vegetarian version, swap chicken for hearty vegetables like eggplant or cauliflower steaks. The sauce is rich enough to stand on its own and still satisfy.
What’s the best way to chop sun-dried tomatoes?
For even cooking and texture, roughly chop sun-dried tomatoes into bite-sized pieces. If they’re dry, soaking them briefly in warm water will soften them before chopping.
Can I prepare the sauce ahead of time?
Yes, you can make the creamy tomato-spinach sauce a day ahead and refrigerate it. When ready, heat gently before pouring over the chicken and baking.
