Ingredients List

To whip up my Creamy Chicken and Spinach Casserole, you’ll need the following ingredients that come together in a symphony of flavors:

  • 2 large boneless, skinless chicken breasts
  • 2 tbsp olive oil, divided
  • 3 cloves garlic, minced
  • 1 tbsp Italian seasoning
  • ½ tsp salt
  • ½ tsp black pepper
  • 2 cups fresh spinach, packed
  • 8 oz cream cheese, softened for easy mixing

  • ½ cup Parmesan cheese (optional but oh-so-delicious)

Gathering these ingredients is half the fun, and trust me, they’ll transform into a dish that’s not just tasty but also utterly comforting. So, let’s get cooking!

How to Prepare Creamy Chicken and Spinach Casserole Instructions

Now that you have your ingredients ready, let’s dive into making this delicious Creamy Chicken and Spinach Casserole! I promise you, it’s easier than it sounds, and your family will be raving about it in no time.

Prepping the Chicken

First things first, let’s get our chicken ready! Start by slicing the chicken breasts horizontally into four cutlets. This helps them cook evenly and quickly, which is key for a tender result. Once you have your cutlets, give them a little love by pounding them to an even thickness. This step is super important for even cooking! Now, let’s marinate. In a bowl, mix 1 tablespoon of olive oil with minced garlic, Italian seasoning, salt, and pepper. Toss the chicken in this mixture until it’s nicely coated, and then pop it in the fridge for about 15 to 30 minutes. This extra time allows the flavors to soak in and makes a world of difference!

Cooking the Spinach

Next up, the spinach! In a skillet over medium heat, add a drizzle of your remaining olive oil. Once it’s hot, toss in the fresh spinach and sauté it for about 2 to 3 minutes, or just until it wilts. Keep an eye on it – you want that vibrant green color to remain. Once it’s done, set it aside to cool slightly while you tackle the next steps.

Assembling the Casserole

Now comes the fun part: assembling the casserole! In a mixing bowl, beat the softened cream cheese until it’s nice and smooth. Then, stir in the sautéed spinach and half a cup of the shredded mozzarella cheese, along with Parmesan cheese if you’re using it. This mixture is going to be the creamy goodness that binds everything together. Arrange your marinated chicken cutlets in a greased 9×13-inch baking dish, then spread that luscious spinach and cream cheese mixture over the top. Finally, sprinkle the rest of the mozzarella cheese evenly on top for that gorgeous melty finish!

Baking the Casserole

It’s time to bake! Preheat your oven to 400°F (200°C) if you haven’t already. Slide the casserole into the oven and let it bake for about 20 to 30 minutes. You’ll know it’s done when the chicken is cooked through (it should reach an internal temperature of 165°F) and the cheese is beautifully melted and lightly golden. Once it’s out of the oven, let it rest for about 5 minutes before serving. This waiting period allows the flavors to settle and makes it easier to portion!

Storage & Reheating Instructions

To store any leftovers of your Creamy Chicken and Spinach Casserole, let it cool completely, then transfer it to an airtight container. It’ll keep in the fridge for about 3 to 4 days. When you’re ready to enjoy it again, simply reheat in the oven at 350°F (175°C) for about 15–20 minutes, or until warmed through. You can also microwave individual portions for a quick meal, just be careful not to overcook!

FAQ Section

Here are some common questions I get about my Creamy Chicken and Spinach Casserole that might help you out:

  • Can I use frozen spinach instead of fresh? Absolutely! Just be sure to thaw it first and squeeze out any excess moisture. This keeps your casserole from getting watery and ensures every bite is delicious.
  • What if I don’t have cream cheese? You can substitute Greek yogurt or ricotta cheese for a lighter option. Just keep in mind that the flavor and texture will vary slightly, but it’ll still be yummy!
  • How can I make this dish gluten-free? No problem! Just check that your Italian seasoning is gluten-free and you’re all set. All other ingredients in this recipe are naturally gluten-free.
  • Can I prepare this casserole ahead of time? Yes! You can assemble it the night before and store it in the fridge. Just pop it in the oven when you’re ready to bake!
  • How do I know when the chicken is cooked through? Use a meat thermometer to check for an internal temperature of 165°F (75°C). This ensures your chicken is safe and perfectly juicy!
