    • 📖 Recipe

    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.

    step by step recipe images

    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.

    baking casserole

    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.

        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.

        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.

        The spinach should be drained and squeezed of most of the liquid. Maybe that was it?

        I've always cooked the chicken first. Might need to cover and cook longer if the chicken is raw.

      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

          There's no cream of mushroom soup called for. Are you wanting to sub out the sour cream?

          You can use the same amount, about 10 ounces.

      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.
