Fire up your oven to a toasty 375°F (190°C) so it’s perfectly ready for our delicious creation.

Grab a large skillet and drizzle olive oil.

Toss in sliced mushrooms and let them dance and sizzle until they turn golden brown and tender, about 5-7 minutes. Scoop them out and set aside.

In the same skillet, welcome the chopped spinach. Let it wilt and soften for 2-3 minutes, then remove and keep close.

• Chicken broth
• Garlic powder
• Onion powder

Whisk everything together until smooth and dreamy.

Grease a 9×13-inch casserole dish.

Spread out the cooked chicken as your first layer, then sprinkle the sautéed mushrooms and spinach on top.

Step 6: Pour the Cream

Gently cascade the creamy mixture over the layers, making sure every morsel gets a coating of deliciousness.

Step 7: Cheese Shower

• Grated mozzarella
• Grated Parmesan

Cover the top like a cheesy blanket.

Step 8: Bake to Perfection

Slide the casserole into the oven and bake for 20-25 minutes.

Watch for the cheese to melt, bubble, and turn a beautiful golden brown.

Step 9: Fresh Finish

Shower some fresh parsley on top for a pop of color and extra flavor.

Serve hot and enjoy!

Tips for Creamy Chicken Casserole Success

• Use room temperature cream cheese for smoother, lump-free mixing in the sauce.
• Sauté mushrooms until golden brown to develop rich, caramelized taste that enhances the entire dish.
• Cover casserole with foil during first 15 minutes of baking to prevent cheese from burning and maintain creamy texture.
• Replace chicken with cauliflower or zucchini for a vegetarian-friendly alternative that keeps the same delicious creamy profile.
• Make the casserole ahead and refrigerate up to 24 hours before baking, allowing flavors to meld and intensify.

Flavor Options for Creamy Chicken Casserole

• Protein Power-Up Variation: Replace chicken with diced turkey or lean ground beef for a protein-packed alternative that maintains the casserole's creamy texture and flavor profile.
• Dairy-Free Delight: Substitute cream cheese with cashew cream, use coconut milk instead of sour cream, and opt for dairy-free mozzarella to create a lactose-free version that's equally satisfying.
• Mediterranean Herb Remix: Add chopped sun-dried tomatoes, swap green onion cream cheese for herbed goat cheese, and sprinkle oregano and basil to transform the casserole into a Mediterranean-inspired dish with bright, fresh flavors.

Pairings for Chicken Casserole

• Pair this creamy chicken casserole with a crisp Sauvignon Blanc that cuts through the richness and complements the earthy mushrooms.
• Roast some herbed garlic bread or a light quinoa salad to balance the casserole's creamy texture and provide a refreshing contrast.
• Select a medium-bodied Chardonnay with subtle oak notes that harmonizes with the melted cheese and enhances the chicken's savory profile.
• Brew a fresh herb tea like thyme or rosemary to cleanse the palate and add an aromatic dimension that echoes the casserole's green ingredients.

Proper Storage for Creamy Chicken Casserole

• Store leftovers in an airtight container within 2 hours of cooking. Keep refrigerated for 3-4 days, ensuring the container is sealed tightly to maintain freshness and prevent bacterial growth.
• Transfer cooled casserole to a freezer-safe dish, cover with plastic wrap and aluminum foil. Freeze for up to 2 months. Label the container with the date and contents for easy tracking.
• Preheat oven to 350°F. Remove casserole from refrigerator, let sit at room temperature for 15 minutes. Cover with foil to prevent drying, bake for 20-25 minutes until heated through. Remove foil for the last 5 minutes to crisp the cheese.

FAQs

• Can I use frozen spinach instead of fresh spinach?

Yes, you can use frozen spinach. Just make sure to thaw and drain it completely, squeezing out excess moisture before adding to the casserole to prevent a watery dish.

• Is it possible to make this casserole ahead of time?

Absolutely! You can prepare the casserole up to the point of baking, cover it, and refrigerate for up to 24 hours. When ready to serve, bake it directly from the refrigerator, adding a few extra minutes to the cooking time.

• What type of chicken works best for this recipe?

Rotisserie chicken, shredded chicken breast, or leftover grilled chicken all work perfectly. Just ensure the chicken is cooked and roughly chopped or shredded before layering in the casserole.
