Ingredients You’ll Need
Chicken
- 1.5 to 2 pounds boneless skinless chicken breasts
- Slice large breasts in half horizontally so they cook evenly.
- You can swap in boneless skinless chicken thighs if you prefer darker meat and extra juiciness.
Spinach
- 8 ounces fresh baby spinach, roughly chopped
- Pre-washed baby spinach saves time and avoids extra dishes.
- Use 10 ounces frozen chopped spinach (thawed and squeezed very dry) if you want a budget pantry option.
Creamy Base
-
8 ounces cream cheese, softened
- Use full-fat cream cheese for the creamiest texture.
- A brick-style cream cheese works better than whipped versions.
-
1 cup sour cream or plain Greek yogurt
- Sour cream gives a classic tangy flavor.
- Greek yogurt adds extra protein and still tastes great.
-
1 cup shredded mozzarella cheese
- Pre-shredded mozzarella works fine here and saves time.
- Low-moisture part-skim mozzarella melts nicely and browns well.
-
1/2 cup grated Parmesan cheese
- Use real Parmesan if you can; it adds nutty, salty depth.
- Shelf-stable grated Parmesan works in a pinch and keeps well in the pantry.
-
1/2 cup chicken broth
- Use low-sodium broth so you control the salt level.
- Bouillon paste mixed with water works as a handy pantry backup.
Flavor Boosters
- 3 cloves garlic, minced
- 1 teaspoon onion powder
- 1 teaspoon Italian seasoning
- 1/2 teaspoon smoked paprika or sweet paprika
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
Optional Add-ins
- 1 cup cooked rice or cooked small pasta
- Stir into the sauce if you want a more filling casserole.
- 1/2 cup cooked bacon bits or chopped cooked bacon
- Adds a smoky, salty punch.
- 1/2 cup chopped sun-dried tomatoes (packed in oil, drained)
- Adds tangy, savory flavor and pretty color.
Topping
- 1/2 cup shredded mozzarella cheese
- 2 tablespoons grated Parmesan
- 1/3 cup panko breadcrumbs or regular breadcrumbs
- 1 tablespoon olive oil or melted butter
- Pinch of salt and pepper
Equipment List
- 9×13 inch baking dish
- Large mixing bowl
- Whisk or sturdy spoon
- Cutting board and sharp knife
- Measuring cups and spoons
- Foil (to cover if it browns too fast)
- Tongs or spatula for serving
Tips & Tricks
- Soften the cream cheese fully so it blends smoothly and avoids lumps in the sauce.
- Pat the chicken dry with paper towels so the seasoning sticks and the casserole does not water out.
- Squeeze frozen spinach very dry if you use it, or the sauce turns thin and watery.
- Season the chicken generously on both sides so every bite tastes flavorful.
- Cut chicken into even thickness so it cooks at the same rate and stays juicy.
- Use low-sodium broth and taste the sauce before baking, then adjust salt so it suits your preference.
- Cover loosely with foil if the top browns too quickly while the chicken finishes cooking.
- Let the casserole rest 5 to 10 minutes after baking so the sauce thickens and slices hold together.
- Add cooked rice or pasta directly to the sauce if you want a full one-pan meal.
- Use a thermometer and cook chicken to 165°F so it stays safe yet tender.
How to Make Chicken and Spinach Casserole with Cream Cheese
Step 1: Prep the Oven and Pan
Preheat your oven to 375°F. Grease a 9×13 inch baking dish with a little olive oil or cooking spray. Set the dish aside while you mix the creamy spinach base.
Step 2: Season the Chicken
Pat the chicken breasts dry with paper towels. Sprinkle both sides with salt, pepper, a little paprika, and a pinch of Italian seasoning. Lay the seasoned chicken in a single layer in the prepared baking dish.
Step 3: Mix the Creamy Spinach Sauce
Add softened cream cheese, sour cream or Greek yogurt, chicken broth, garlic, onion powder, Italian seasoning, paprika, salt, and pepper to a large mixing bowl. Whisk or stir until the mixture looks smooth and creamy with no big cream cheese chunks. Stir in the mozzarella and Parmesan until they distribute evenly.
Fold the chopped spinach into the creamy mixture. If you use frozen spinach, break up any clumps and mix until everything looks evenly green and cheesy. Add any optional cooked rice, pasta, bacon, or sun-dried tomatoes and stir again.
Step 4: Assemble the Casserole
Spread the creamy spinach mixture over the chicken in the baking dish. Make sure the sauce covers the chicken completely so it stays moist and tender. Smooth the top with a spatula so it bakes evenly.
Step 5: Add the Topping
In a small bowl, mix panko breadcrumbs, mozzarella, Parmesan, olive oil or melted butter, and a pinch of salt and pepper. Stir until the crumbs look evenly coated and slightly clumpy. Sprinkle this mixture evenly over the top of the casserole.
Step 6: Bake
Place the baking dish on the middle rack of the oven. Bake for 25 to 35 minutes, depending on the thickness of your chicken pieces. Check the internal temperature of the thickest piece and pull the dish out when it reaches 165°F and the top looks golden and bubbly.
If the top browns too quickly, tent the dish loosely with foil and finish baking. If the chicken needs a few more minutes, keep checking every 3 to 5 minutes so it does not overcook.
Step 7: Rest and Serve
Let the chicken and spinach casserole with cream cheese rest for 5 to 10 minutes on the counter. This short pause lets the sauce thicken and makes serving easier. Slice or scoop portions of chicken with plenty of creamy spinach and cheesy topping in every serving.
What to Serve with Chicken and Spinach Casserole with Cream Cheese
Serve this chicken and spinach casserole with cream cheese with a simple green salad, tossed with a light vinaigrette to balance the richness. Steamed broccoli, green beans, or roasted carrots pair nicely and keep the plate colorful. You can add crusty bread, garlic toast, or warm dinner rolls to soak up the creamy sauce. If you want a lighter side, serve it with sliced cucumbers and cherry tomatoes dressed with a squeeze of lemon and a pinch of salt.
Storage Options
- Store leftovers in an airtight container in the fridge for up to 3 to 4 days.
- Reheat single portions in the microwave in 45 to 60 second bursts, stirring gently between bursts so the sauce heats evenly.
- Reheat a larger portion in a covered baking dish at 325°F until hot and bubbly, about 15 to 20 minutes.
- Freeze cooled casserole portions in freezer-safe containers for up to 2 months.
- Thaw frozen portions overnight in the fridge, then reheat gently so the cream cheese sauce stays creamy and does not separate.
