How to Make Healthy Chicken Spinach Casserole For Delicious Weeknights
Step 1: Prep and Preheat
First things first, set your oven to 375°F (190°C) and lightly grease your baking dish. Getting this ready early makes the assembly and baking process smooth and stress-free.
Step 2: Sauté the Chicken with Seasonings
Heat your olive oil in a skillet over medium heat. Toss in the cubed chicken along with garlic powder, oregano, paprika, salt, and pepper. Cook the chicken for about 6 to 8 minutes until the pieces are lightly browned but not fully cooked through yet. This step locks in flavor while keeping the chicken tender.
Step 3: Add Vegetables
Now, stir in the chopped spinach and mushrooms if you’re using them. Cook everything together for another 2 minutes until the spinach wilts just enough. This ensures your veggies stay vibrant and add a lovely freshness to the casserole.
Step 4: Mix the Creamy Base
In a separate bowl, combine your Greek yogurt with the cream cheese or ricotta (if using) and half of your mozzarella cheese. Season lightly with salt and pepper as needed. This luscious, creamy base ties all the elements of the casserole together while keeping it wholesome.
Step 5: Combine and Transfer
Gently fold the chicken and spinach mixture into your creamy sauce until everything is well-coated. Then spread this mixture evenly into your prepared baking dish. Even layering helps the casserole cook uniformly and brings out the flavors in every bite.
Step 6: Top and Bake
Sprinkle the remaining mozzarella on top, and if you like, add grated Parmesan for an extra cheesy crust. Pop your casserole into the oven and bake for 20 to 25 minutes until it’s golden, bubbly, and the chicken is fully cooked through. Your kitchen will soon smell like pure comfort!
Step 7: Cool and Serve
Once out of the oven, let the casserole cool for a few minutes. This resting time allows everything to set nicely, making it easier to serve. A sprinkle of red pepper flakes or fresh parsley on top adds a beautiful finishing touch.

Make Ahead and Storage
Storing Leftovers

Reheating
Reheat leftovers in a covered dish in a 350°F (175°C) oven for about 15-20 minutes or until warmed through. You can also microwave single servings, just cover loosely and heat in short bursts to maintain creaminess and texture.
FAQs
Can I use frozen spinach instead of fresh?
Absolutely! Just make sure to thaw and squeeze out any excess water from the frozen spinach before adding it to the casserole. This keeps the dish from getting too watery.
Is this casserole suitable for meal prep?
Definitely. It’s ideal for meal prep since it stores well in the fridge and freezer, and it reheats nicely without losing texture or flavor.
Can I substitute the chicken with turkey or tofu?
Yes, ground turkey or cubed tofu can be great substitutes. Just adjust the cooking time accordingly to ensure they’re cooked through and flavorful.
How can I make this casserole dairy-free?
Swap the Greek yogurt and cheeses for plant-based versions like coconut yogurt and vegan mozzarella. The dish will still be creamy and tasty with these alternatives.
What if I want it spicier?
Feel free to increase the red pepper flakes or add a dash of cayenne pepper in the seasoning step. Fresh chopped jalapeños also work well mixed in before baking.
