How to Make Creamy Chicken and Spinach Casserole
-
Preheat the oven to 375°F (190°C) and grease a baking dish. This first step ensures your dish is ready to go, preventing any sticking and making for easy cleanup later.
-
Sear the chicken in a skillet over medium heat with olive oil. Season with salt and pepper, and cook until golden brown (about 5 minutes per side). Removing it from the pan locks in those savory juices.
-
Sauté the minced garlic in the same skillet until fragrant. Stir in the heavy cream and soy sauce, letting the wonderful scents take over your kitchen as they meld into a delightful sauce.
-
Add the fresh baby spinach to the sauce, allowing it to wilt for about 2 minutes. Slice the seared chicken and combine it with the creamy mixture, inviting all those flavors to unite beautifully.
-
Pour the chicken and sauce mixture into your greased baking dish. Top with shredded mozzarella and grated parmesan cheese, creating a cheesy layer that promises gooey goodness.
-
Bake for 25-30 minutes until bubbly and golden brown. Let sit for 5 minutes before serving, allowing the casserole to settle, making it easier to serve.

Make Ahead Options
These Creamy Chicken and Spinach Casseroles are perfect for meal prep enthusiasts! You can season and sear the chicken up to 24 hours in advance, allowing you to skip this step during the busy week. The fragrant sauce can also be prepared ahead; simply sauté the garlic and mix in the heavy cream and soy sauce, then allow it to cool before refrigerating. For the best results, assemble the casserole (combine chicken, sauce, and spinach) and top with cheese up to 3 days ahead of time and store it covered in the fridge. When you’re ready to cook, simply bake it straight from the refrigerator, adding an extra 5-10 minutes to the cooking time for perfectly cheesy, creamy results that are just as delicious as fresh!

Chef's Helpful Tips
- When making Creamy Chicken and Spinach Casserole, ensure your chicken is properly seared to lock in moisture and enhance flavor; be patient and allow it to cook undisturbed for even browning.
- Avoid overcooking the spinach; adding it to the sauce just before combining with the chicken helps retain its vibrant color and nutrients.
- For a twist on flavors, experiment by adding different cheeses such as gouda or adding a hint of nutmeg to the cream sauce.
- Keep an eye on the casserole as it bakes, checking for the cheese to be melted and golden, as every oven can vary slightly in temperature.
Creamy Chicken and Spinach Casserole Recipe FAQs

Absolutely! Look for boneless, skinless chicken breasts that are firm and pink in color without any dark spots. Avoid chicken with a slimy texture or an unpleasant odor, as these are signs of spoilage.

What if my casserole turns out too runny?
No worries! If your casserole is too runny, you can return it to the oven and bake it a little longer uncovered to allow excess liquid to evaporate. Alternatively, you can add a thickening agent like cornstarch mixed with a bit of cold water, stirring it into the hot mixture until it thickens.
