Key Ingredients & Substitutions
Cooked Chicken: Using cooked chicken makes this casserole quick. You can use rotisserie chicken or even leftover chicken for added convenience. If you’re vegetarian, consider chickpeas or white beans as a hearty substitute!
Fresh Spinach: Fresh spinach adds vibrant color and nutrients. If you can’t find it, frozen spinach works too—just make sure to thaw and drain it well to avoid excess liquid.
Cream Cheese: This ingredient gives the casserole its creamy texture. If you’re looking for a lighter version, you can use Neufchâtel cheese or Greek yogurt as a substitute. They will still provide creaminess while cutting back on calories.
Sour Cream and Mayonnaise: Both add richness. You can replace sour cream with plain yogurt or cottage cheese. If you want dairy-free, try a vegan mayonnaise or almond-based yogurt.
Cheeses: Mozzarella and Parmesan take the top layer to the next level. If you’re out of Parmesan, try Pecorino Romano or nutritional yeast for a cheesy flavor without dairy.
How Do I Sauté Onions and Garlic Perfectly?
Sautéing onions and garlic brings out their delicious flavors. Here’s how to do it right:
- Heat olive oil or butter in your skillet over medium heat.
- Add the chopped onions first, cooking for about 2-3 minutes until they’re soft.
- Then add the minced garlic and sauté for another minute until fragrant. Be careful not to burn the garlic, as it can turn bitter!
This technique is simple but essential for building a flavorful base for your casserole!

How Much Time Will You Need?
This delicious chicken and spinach casserole takes about 10 minutes to prepare and 25-30 minutes to bake. So, in just under an hour, you’ll have a delightful, comforting meal ready to enjoy with family or friends!
Step-by-Step Instructions:
1. Preheat the Oven:
First, get your oven ready! Preheat it to 350°F (175°C) so it’s nice and warm when the casserole is ready to bake.
2. Sauté the Onions and Garlic:
In a large skillet, heat the olive oil or butter over medium heat. Add the finely chopped onions and minced garlic. Sauté them for about 3-4 minutes until the onions are soft and the garlic is fragrant. This step is crucial for building a flavor-packed base!
3. Wilt the Spinach:
Next, add the chopped spinach to the skillet. Cook for just a few minutes until it’s wilted. Once it’s cooked down, remove the skillet from heat and set the spinach mixture aside.
4. Mix the Creamy Base:
In a large bowl, combine the softened cream cheese, sour cream, and mayonnaise. Use a whisk or spatula to mix until everything is smooth and well blended. This creamy base will give the casserole its rich texture.
5. Combine Ingredients:
Now, stir in the cooked spinach mixture, along with any remaining sautéed onion and garlic. Add the Italian seasoning, crushed red pepper flakes (if you want a little kick), salt, and pepper. Mix well!
6. Add the Chicken:
Gently fold in the cooked chicken pieces, ensuring they’re evenly coated in the creamy mixture. This will help distribute the flavors throughout the casserole.
7. Prepare for Baking:
Transfer the entire mixture into a greased or non-stick casserole dish, spreading it out evenly. It’s ready for its cheesy topping!
8. Top with Cheese:
Sprinkle the shredded mozzarella and grated Parmesan cheese over the top of the casserole. This will create a lovely, bubbly, and golden crust as it bakes.
9. Bake the Casserole:
Pop the casserole into the preheated oven and bake uncovered for 25-30 minutes. You’ll know it’s done when the top is golden brown and bubbly. Mmm, it smells amazing!
10. Let it Rest:
Once it’s out of the oven, let the casserole rest for about 5 minutes. This helps it set a bit, making it easier to serve. Then, dig in and enjoy your creamy, cheesy chicken and spinach casserole warm as a comforting main dish!
Can I Use Leftover Rotisserie Chicken for This Recipe?
Absolutely! Leftover rotisserie chicken is a fantastic option. Just shred or chop it into bite-sized pieces and mix it right into the casserole. It will save you time and add great flavor!
Can I Make This Casserole in Advance?
Yes! You can prepare the casserole a day ahead, assemble it in the dish, cover it tightly with plastic wrap, and refrigerate. When you’re ready to bake, just pop it in the oven—add an extra 5-10 minutes to the baking time if it’s cold from the fridge.
What’s the Best Way to Reheat Leftovers?
To reheat leftovers, place the casserole in a preheated oven at 350°F (175°C) for about 15-20 minutes, or until heated through. You can also microwave individual portions, covering them with a damp paper towel to maintain moisture.
Can I Freeze This Casserole?
Yes! This casserole freezes well. To freeze, let it cool completely, then wrap tightly in plastic wrap and aluminum foil. When ready to eat, thaw it in the fridge overnight and reheat in the oven or microwave.
