How to Make Baked Tuscan Chicken Casserole

Let me show you how easy it is to make this Baked Tuscan Chicken Casserole:

Prepare Chicken and Baking Dish

1. I lay the chicken breasts flat on the bottom of a large baking dish.
2. I season the chicken breasts with salt, pepper, and half of the minced garlic.

Preheat Oven

1. I preheat my oven to 400ºF (200ºC).

Make Cream Cheese Topping

1. In a bowl, I mix the thawed and squeezed-dry spinach, softened cream cheese, and heavy cream.
2. I add the remaining half of the minced garlic, salt, onion powder, chili powder, black pepper, and Italian seasoning. I beat everything to combine.
3. I add the Parmesan cheese and half of the mozzarella cheese and continue beating to combine.

Assemble Casserole

1. I spread the spinach and cream cheese mixture on top of the chicken breasts.
2. I top with the chopped sun-dried tomatoes.
3. Then I drizzle with a tablespoon of the reserved oil from the sun-dried tomatoes jar.
4. I finish by topping the chicken casserole with the remaining mozzarella cheese.

Bake

1. I bake the Tuscan chicken casserole for 35 minutes: I cook for 20 minutes loosely covered with foil.
2. Then I uncover and bake for another 15 minutes, or until the chicken is cooked through (internal temperature should reach 165˚F / 74ºC) and the cheese is bubbly and golden.

Serve

1. Garnish and serve

Tips and Tricks for the BEST Tuscan Chicken

Here are my secrets for making this casserole truly exceptional:

• Squeeze Spinach Dry: Removing as much moisture as possible from the thawed spinach is crucial to prevent a watery topping.
• Room Temperature Cream Cheese: Softened cream cheese mixes much more easily and smoothly.
• Don't Overcook Chicken: Use a meat thermometer to ensure the chicken reaches 165°F (74°C) without overcooking, keeping it tender and juicy.
• Sun-Dried Tomato Oil: Using the oil from the sun-dried tomato jar adds extra flavor.
• Freshly Grated Parmesan: Melts better and tastes superior to pre-shredded.

How to Serve

This Baked Tuscan Chicken Casserole is delicious served with:

• Cauliflower Rice: A great low-carb option, as pictured in the original recipe source.
• Zucchini Noodles: Another fantastic low-carb pairing.
• Pasta: Serve over angel hair pasta or linguine to soak up any extra sauce.
• Rice: White or brown rice works well too.
• Steamed Vegetables: Asparagus or green beans are lovely accompaniments.
• Crusty Bread: For dipping into the creamy sauce.

Make Ahead and Storage

You can assemble the casserole ahead of time (up to 24 hours) and store it, covered, in the refrigerator before baking. You may need to add a few extra minutes to the baking time if baking straight from the fridge. Leftover casserole can be stored in the refrigerator for up to 3 days. Reheat gently in the oven or microwave.

FAQs about Baked Tuscan Chicken Casserole

• Can I use fresh spinach instead of frozen?
  • Yes, wilt fresh spinach by sautéing it briefly before adding it to the cream cheese mixture. Make sure to squeeze out excess moisture.
• Can I use chicken thighs?
  • Absolutely! Boneless, skinless chicken thighs would be very flavorful and moist. Adjust baking time as needed.
• Can I freeze this casserole?
  • Yes, you can freeze the baked and cooled casserole. Thaw overnight in the refrigerator before reheating.

Enjoy this creamy, flavorful, and easy-to-make Baked Tuscan Chicken Casserole! It's a perfect meal for any night of the week.
