Many readers have made it with different variations including chicken thighs, bacon, served over rice, Brussel sprouts, steamed cauliflower, noodles, and even pesto pasta! It’s kid-approved and super easy for the home cook to make for busy weeknight dinners. I’ve even been messaged on how good this chicken dish was!
So, where did I get this easy chicken casserole recipe? Well, when a friend shared thisCreamy Spinach Tilapia casseroleyears ago, (I know you can even make fish taste good with this recipe), I decided to make this casserole with chicken too. As easy and quick as it was I’m glad I shared this cheesy chicken casserole because many of you love it! It has also been named Keto Chicken so, it happens to be gluten-free and low-carb!
- Fresh spinach-pack that casserole with an 8oz package of fresh spinach (you can use frozen spinach too.)
- Chicken breasts-slice 2 large chicken breasts in half crosswise to make 4 fillets or pick up thinly sliced chicken breasts from the store.
- Mayonnaise- you could substitute a creamy salad dressing however, adjust the garlic salt to your liking.
- Sour cream- a substitute for sour cream here, is yogurt.
- Cheese-I use freshly grated parmesan cheese for the cheese sauce and shredded Monterey Jack cheese for the top (using a box grater.) Feel free to use shredded mozzarella cheese or other cheese blends. (Note: if you pick a cheddar cheese blend the cheese crust can get yellow and dark brown.)
- Seasoning-the parmesan cheese and mayo already have salt so, go be careful not to oversalt this chicken casserole. Feel free to use adobo seasoning for the chicken breasts.

Q&A
What Is a Spinach and Chicken Recipe?
A chicken and spinach bake is a chicken breast dish smothered with a creamy cheese mixture and then topped with grated cheese and baked. This makes an easy chicken casserole as you do not need to pre-cook the chicken breast meat or spinach. Serve it with healthy sides of broccoli or wild rice!
What Sides Go With Chicken Casseroles?
Creamy Chicken Casserole Recipes go with many side dishes as this makes a main coarse meal! Eat this chicken dish with a side of pasta or bread and for low-carb options serve it with Zucchini zoodles or steamed veggies. Here are some recipe ideas:
- Pasta noodles or Fettucine Alfredo
- Stovetop Rice
- Mashed Potatoes
- French Bread- or garlic bread
- Creamy Cucumber Tomato Avocado Salad
- Cooked grains like Farro.
- Outback Broccoli and Cheese
- Oven-Baked Potato Wedges
- Spaghetti Squash,Steamed Asparagus, or broccoli
How Long To Cook Chicken?
How long to bake chicken breast casserole depends on the thickness of your meat. To cook this, first slice the chicken breasts in half and assemble.
Chicken is done when it reaches an internal temperature of 165°F. Depending on how thick your chicken breast fillet is, it can take anywhere from 18-25 for the chicken to bake at 500°F. My chicken breast was sliced in half crosswise and cooked fully in a 25 minute-range.
Chicken Casserole Variations:
There are so many different add-ins you can add when baking this chicken! These variations are to be baked together with the chicken:
- Spinach Chicken and Sausage-add 8 oz of your favorite sliced sausage.
- Creamy Chicken Casserole with Shrimp-add 6 oz of cooked shrimp and 1 Tbsp of minced garlic to the chicken.
- Creamy Salmon Casserole-Substitute with 4 salmon fillets and dollop spinach with 4 tablespoons of butter.
- Herbed Mushrooms and butter- saute mushrooms in butter and Italian seasoning.
- Chicken Bacon and Ranch Casserole- add 1/2 cup ofbacon bits and use ranch dressing instead of the mayonnaise.
- Tuscan Chicken Thighs-use 4 skin-on boneless chicken thighs instead of chicken breasts.
- Asparagus and Shrimp-place 2 cups of cut asparagus to the bottom of the casserole and layer as instructed.
- Chicken Broccoli and Rice Casserole-add 8 oz of cooked rice (or 1-8.8 oz microwavable rice packet) and 2 cups of cut broccoli to the bottom of the casserole. Layer as instructed.
Note:for keto chicken, serve with low-carb add-ins or sides.
What Cheese is Best For Creamy Chicken Casserole?
The best cheese is Monterey Jack. We used parmesan cheese for the sauce mixture and that is plenty of salty so be careful with how much salt you add. A mildly flavored melting cheese is one that you want to choose. Another popular white cheese that can be used is Mozzarella cheese.
Storing Creamy Chicken Casserole?
If you have any leftovers they reheat great! Leftovers can be stored in an airtight container in the fridge for up to 5 days and reheated in a skillet or microwave.
To reheat chicken: microwave in 30-second intervals until hot. You could also place leftovers into a buttered pan and heat them covered over medium heat until warm.
Can Chicken And Spinach Casserole Be Frozen?
This casserole is loaded with spinach, raw meat, and dairy products. Therefore if you freeze this uncooked, it may result in a high-water content casserole that can turn out grainy. However, you can make ahead this casserole and store it in the fridge for up to one day (assembled.)
Best Casserole Tips:
- Use a heavy dutch-oven casserole or a stainless steel dish. The oven temperature gets quite high for this chicken recipe.
- Shredd a block of your favorite white cheese for a speckled brown cheese crust. My favorites, are a Mozzarella and parmesan cheese blend and Monterey Jack (the white block not the Colby blend.)
- To use frozen spinach squeeze out the excess liquid.
- When using fresh spinach a lot of readers found that the fresh spinach got a little runny on the bottom so, you can add a layer of cauliflower or parboiled rice to the bottom this should soak up any excess liquid. Note: you may need to bake longer.
- Since this chicken casserole is gluten-free, Keto, and Low-carb you can pair it with more low-carb dishes like steamed vegetables, Zoodles, brown rice, and grains.
- Serve this with pasta noodles, cooked white rice, mashed potatoes, or crusty bread!
- This chicken casserole bakes at 500°F to wilt the spinach and cook the chicken thoroughly. Baking this dish at such a high temperature also creates a speckled cheese crust.
What You Need To Make This Chicken Casserole:
- One 13×9 baking dish.

I made this in the camper on top of the stove. I also followed the suggestion of using a potato. So I cooked the potato and chicken first, seasoning my chicken well, followed by adding the spinach. After the spinach had wilted, I put the sauce on and covered it with a lid for just a short time. It was OUTSTANDING!!

Tip on spinach: buy fresh baby spinach, transfer it to a Ziploc freezer bag, I use layers of parchment paper to separate the spinach. Freeze. Freezing the spinach wilts it and super easy to add portions to recipes just by crumbling up the bag while frozen.

What temp would you recommend in a tiny gas oven?

I’m not sure, what would the highest temp be in your gas oven?

500, but I can’t move it into a lower position. Flame is from underneath.
I have just enough space for the baking dish.- Reply

I know you recommend a heavy cast iron pan, but have you ever cooked this in a disposable tin pan? I’d love to make this for a grieving family, but I don’t want them to have to worry about returning a pan. I’m wondering if the bottom will burn in such a thin pan at such high heat.

Hi Liv, a disposable pan should work, you can always decrease the cooking temperature to 450F.

This was very good. Making it a 2nd time tonight. Super easy and very tasty. Only change I made was I used a rotisserie chicken, as that is all I had on hand and I added about a TBSP of fresh lemon juice to the mayo/sour cream sauce.

The lemon juice sounds delish! I’m happy you’re enjoying the recipe.
