This chicken and spinach casserole is a warm and tasty dish that’s perfect for dinner. With tender chicken, fresh spinach, and gooey cheese, each bite is a little hug for your tummy!
What I love most is how easy it is to toss everything together. It makes a great meal for busy nights, and leftovers? Yum! They taste even better the next day!
Key Ingredients & Substitutions
Chicken: Boneless, skinless chicken breasts are great for this dish. If you want to save time, you can use rotisserie chicken, just shred it before adding it to the casserole.
Spinach: Fresh spinach adds flavor, but if you’re in a pinch, frozen spinach works well too! Just be sure to thaw and drain it thoroughly to avoid excess moisture.
Cream Cheese: This is essential for creaminess. If you’re looking for a lighter option, you can use neufchâtel cheese or a dairy-free cream cheese for a vegan alternative.
Sour Cream/Yogurt: I like sour cream for tanginess, but Greek yogurt is a fantastic substitute that adds extra protein and creaminess.
Cheese: While mozzarella is a must for cheesiness, feel free to mix in other cheeses like cheddar for added flavor. Just keep an eye on the melting properties.
How Do I Perfectly Sauté Spinach Without Making It Soggy?
Sautéing spinach should be quick to avoid sogginess. Here’s how to get it right:
- Use medium heat and quickly add your garlic to a hot skillet with butter.
- Add the fresh spinach, stirring it frequently for just 2-3 minutes until it wilts.
- Make sure any frozen spinach is thoroughly thawed and pressed to remove excess water before adding it.
- Cook just until moisture is evaporated to prevent a watery casserole.
How to Make Chicken and Spinach Casserole

For the Casserole:
- 4 boneless, skinless chicken breasts
- 1 tablespoon olive oil
- Salt and pepper, to taste
- 4 cups fresh spinach (or 1 package frozen spinach, thawed and drained)
- 1 cup cream cheese, softened
- 1 cup sour cream or Greek yogurt
- 1/2 cup grated Parmesan cheese
- 1 1/2 cups shredded mozzarella cheese, divided

- Optional: 1/4 teaspoon red pepper flakes for a bit of heat
How Much Time Will You Need?
This delicious Chicken and Spinach Casserole will take about 15 minutes to prepare and 25-30 minutes to bake. Altogether, you’re looking at around 45 minutes from start to finish. It’s a simple dish that packs in a lot of flavor and is perfect for a cozy dinner!
Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 375°F (190°C). While that’s warming up, lightly grease a casserole dish with cooking spray or a little bit of oil to prevent sticking.
2. Season the Chicken:
Take the chicken breasts and season them generously with salt and pepper on both sides. This adds flavor as they cook.
3. Sear the Chicken:
In a skillet, heat the olive oil over medium-high heat. Once it’s hot, add the chicken breasts. Sear them for about 3-4 minutes on each side until they’re golden brown. They don’t need to be fully cooked yet; just get a nice color on them. After searing, remove the chicken from the skillet and set them aside.
4. Cook the Garlic and Spinach:
In the same skillet, reduce the heat a bit and add the butter and minced garlic. Sauté for about 1 minute until the garlic is fragrant. Then, add in the fresh spinach (or thawed frozen spinach). Cook for about 5 minutes, stirring occasionally, until the spinach is wilted and most of the moisture has evaporated. Once done, remove the skillet from heat.
5. Combine the Cheese Mixtures:
In a large mixing bowl, combine the softened cream cheese, sour cream (or Greek yogurt), grated Parmesan cheese, half of the mozzarella cheese, Italian seasoning, and red pepper flakes if you’re using them. Mix well until all the ingredients are combined smoothly.
6. Mix in the Spinach:
Now, add the cooked spinach and garlic mixture to the cheesy mixture. Stir well to ensure everything is evenly distributed.
7. Assemble the Casserole:
Place the seared chicken breasts evenly in the prepared casserole dish. Next, spread the spinach and cheese mixture generously over the chicken breasts, covering them well. Finally, sprinkle the remaining mozzarella cheese on top for a super cheesy finish!
8. Bake the Casserole:
Put the casserole in the preheated oven (375°F/190°C) and bake uncovered for about 25-30 minutes. You want to ensure the chicken is cooked through to an internal temperature of 165°F (75°C) and that the cheese is bubbly and golden brown.
9. Serve and Enjoy:
Once baked, remove the casserole from the oven and let it rest for a few minutes before serving. Scoop out portions and enjoy your creamy, cheesy chicken and spinach casserole warm. It’s perfect with a side salad or some crusty bread!
Can I Use Frozen Chicken in This Recipe?
Yes, you can use frozen chicken, but make sure to fully thaw it before cooking. Thaw it in the refrigerator overnight or use a quick thaw method by sealing it in a plastic bag and submerging it in cold water until softened. Pat dry to ensure proper searing.
How Can I Make This Ahead of Time?
Absolutely! You can prepare the casserole up to the baking stage, then cover and refrigerate it for up to 24 hours. Just be sure to add a few extra minutes to the baking time if using it straight from the fridge.
What’s the Best Way to Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, pop it in the microwave or warm it up in the oven covered with foil to prevent it from drying out.
Can I Substitute the Cream Cheese?
Yes, you can substitute with neufchâtel cheese for a lighter option or use a dairy-free cream cheese if you’re looking for a vegan alternative. Just ensure it’s softened for easy mixing!
