This easy chicken Florentine casserole is quick and easy to prepare. It's a creamy blend of cut chicken, spinach and Parmesan cheese.
I've been away this week on a business trip this week. I was lucky enough to get a hotel suite that has a full kitchen including stove with oven, full refrigerator and dishwasher.
I booked a one bedroom suite, but those must have gotten overbooked because I ended up in a two bedroom suite. I'm not big into eating out at restaurants, even though the company I work for is paying for my meals while I'm away from home.
I prefer eating meals that I prepare because I know exactly what's in it. So, it was a real treat having the bigger suite with an oven in the kitchen.
Casseroles are simple to prepare. They can easily be thrown together on the spur of the moment as long as you have the basic ingredients.
Since I was cooking away from home, I needed a simple recipe that was going to be quick and easy. For this chicken Florentine casserole recipe, I only needed to buy five ingredients plus a cheap baking pan at the local grocery store near the hotel.
The casserole was enough to feed me for two large double serving dinners and one single serving lunch. This is the first time I've ever made this chicken casserole and you can bet that I will be making it again.
You will need some cooked chicken. I ended up poaching some chicken breasts. But, you can simply use leftover chicken in this casserole.
Either fresh or frozen spinach can be used, too. I usually keep frozen spinach in the freezer so it's usually on hand for me.
The sauce is made with sour cream and mayonnaise. I used store bought mayo. However, homemade is a great option if you have the time to make your own.
I'm a big fan of easy casserole dishes like this chicken Florentine casserole. If you love casseroles too, you may want to check out this post of tasty low carb chicken casserole dishes.
A lot of recipes use condensed cream of mushroom soup as the base for the sauce. We know that this adds unnecessary carbs to the dish!
For those who don't care for mayonnaise, you could make the sauce using a thickened heavy cream instead. You may want to change up the seasoning as well to suit your own taste. I also think adding some bacon would make this dish a bit more delicious.
Other ideas to add to this basic chicken Florentine recipe are mushrooms and mozzarella cheese. Rather than use all Parmesan cheese for the topping, a mix of cheese would be a nice change.

Made this tonight for dinner. Served over palmini noodles simmered for 30 minutes and tossed with olive oil. It was amazing.
Linda ONeal
Do u think canned chicken would work?
Lisa MarcAurele
I have used canned chicken in casseroles so it should work in this dish.

This casserole was quite good. My husband, who suggested low carb, was very satisfied with it. I did add salt, pepper, and garlic powder so it wouldn't be bland.
I needed a lot of food, so I doubled the amounts of chicken and spinach, and used 1.5 times mayo and cheese, and one cup of sour cream. That was plenty. I'm afraid that if I doubled the sauce, it would have drowned the chicken and spinach.
Minor nitpick: Whoever decided prep time would be 10 minutes must have a sous chef, or just didn't include the time needed to cook the chicken and thaw and drain frozen spinach.
It took me more like 30 minutes.
Lisa MarcAurele
Thanks for the feedback on prep time. It typically takes about ten minutes to poach the chicken so that cook time has been accounted for in the cooking time.
Uncle Phil
Awesome!!
Sandy
I served this for dinner to non-keto guests, and they absolutely loved it. I put theirs over fettucine noodles
Maura
This was delicious. My only problem was it was so wet. Anyone know why?
Lisa MarcAurele
The spinach should be drained and squeezed of most of the liquid. Maybe that was it?
Amy Boggs
I made this last night and it was delish!
Sara
Is it necessary to broil the chicken at all? Could I just bake it in the oven for the 35 mins you think? thanks
Lisa MarcAurele
I've always cooked the chicken first. Might need to cover and cook longer if the chicken is raw.
Casey
I substituted plain yogurt for sour cream and topped it with 1/4 cup shredded mozzarella and sprinkled with bacon bits. Absolutely fabulous. Will make it again!
Lisa MarcAurele
That does sound fabulous!
Heather
I didn't have any sour cream so I used cream cheese instead. Also I used fresh spinach & left over rotisserie chicken. My husband loved it! I served this dish w/fresh sliced tomatoes. Yummm
Lisa MarcAurele
Thanks for sharing your version! Cream cheese is a great sub for sour cream.
TAMARA
CAN I USE CREAM CHEESE INSTEAD OF CREAM OF MUSHROOM SOUP? IF SO 4OZ OR THE WHOLE 8 OZ?
Lisa MarcAurele
There's no cream of mushroom soup called for. Are you wanting to sub out the sour cream?
Debbi Wagers
If using fresh spinach how much should you cook up?
Lisa MarcAurele
You can use the same amount, about 10 ounces.
Emily Parker
Will this freeze well?
Lisa
It should based on the ingredients.
Michelle
Yummy! I added the mozzarella on top too. It was a hit for the whole family.
Lisa
Thanks for letting us know it was a hit!
Michelle
This sounds amazing. Is there any way to substitute the sour cream? I just don't have any on hand at the moment
Lisa
You can use yogurt or add a thickener to heavy cream.
Emma Chatman
I just made this and it was delicious. I added heavy whipping cream and asparagus. Will definitely make again
Chelsea Oliveiral
I want to know if you can substitute the sour cream with plain Greek yogurt?
Lisa
I haven't tried it, but it's usually a one-for-one substitute so it should work out okay.
Pam
This was delicious! I'm fairly new to Keto and seem to pick recipes that, well, that I don't like. But this is excellent! And I'll be making it regularly, especially when there are lots of turkey leftovers! I added sliced mushrooms, used heavy cream instead of mayonnaise and sprinkled grated mozzarella cheese on top for the last 10 minutes.
My husband loved it! Thank you for restoring my commitment to eating Keto.
Glenda
This smells Wonderful!!!
CAN'T wait to try it.l didn't change a thing. Going to try more of your recipes. THANKS
Lisa
Enjoy! 🙂
Tammy
I have made this 3 times, it is a delicious dish.
Thanks for sharing!
Lisa
You're welcome! It was one of my go-to recipes when I returned low carb.
Linda V
Would love to have any low carb recipes. I have a real problem getting in veggies since I really only care for limas, green beans, lettuce, zucchini, squash. I like soft onions - just don't like crunch. Love your ideas.
Lisa
There's so many ways to enjoy low carb veggies! Have you tried them as fries? Zucchini fries are delicious!
Linda
Please send me the crunch! I like thin sliced raw or browned and crispy but soft cooked? Not me. Hubby says he thinks I was a horse in a former life! Different strokes?
Elsa
Made this today and it was delicious. I did add broccoli cuts to it though and more cheese because, can you ever have enough cheese?
Lisa
The more cheese the better!
