Why you'll love it
Are you a fan of Italian recipes? What about creamy sauces and rich flavors? If so, then this chicken Florentine recipe is something you will love!
This recipe tastes just like a dish prepared by a 5-star chef - but you can make it at home. I prefer eating meals that I prepare because I know exactly what's in them.
This chicken Florentine recipe is so easy to make that you won't have any problems making a scrumptious dinner, even if you are a beginner cook.
Even better, this chicken florentine is a casserole, and 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.
You only need to buy five ingredients for this chicken Florentine casserole recipe, but you may already have everything in your fridge.
In order to make a chicken Florentine bake, you obviously need a chicken breast or two.
I ended up poaching some chicken breasts. But, you can simply use leftover seared chicken in this casserole.
It is best to use boneless skinless chicken breasts.
Fresh spinach is one of the best vegetables to eat on the keto diet, and luckily, this leafy green veggie is a staple in chicken florentine.
Fresh baby spinach is best, but you can also use frozen spinach. Just remember that frozen spinach will have a different texture than fresh.
I prefer to use fresh spinach because it has a brighter flavor!
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.
You'll find that I use parmesan cheese in many of my favorite keto recipes. This is because it gives the recipes a fantastic earthy and nutty undertone.
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! So instead, use full-fat sour cream.
Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.
- Bake uncovered. If your stove runs hot, cover the chicken Florentine casserole with foil to prevent the top from burning.
- Shred parmesan cheese at home. If you buy pre-shredded parmesan cheese, it will have anti-caking ingredients and hidden carbs in it.
- Watch it closely. Since the chicken is already cooked, you only need to heat this up until it is bubbly and hot. Watch it closely, so it doesn't burn.
Here's how to make homemade chicken florentine. You might be surprised at just how simple this is.
Cook the chicken
The very first step is to cook the chicken breasts. I poached mine, but you can pan-sear them until they are golden brown or even use the air fryer for cooking them.
You can poach the chicken in some water or some chicken broth. Chicken stock works great too!
Make the sauce
Mix the grated parmesan cheese, mayonnaise, and sour cream together in a small mixing bowl.
Arrange the casserole
Place the baby spinach and the cooked chicken breasts in the bottom of the casserole dish. Spread the cheese mixture on top.
Bake the casserole
Bake the chicken Florentine casserole in the oven for about 35 minutes or until the edges are browned.
