Running a meal planning business, I test LOTS of recipes – some flops, some with room for improvement, and some that are just knock-it-out-of-the-ballpark good. This recipe for chicken florentine over acorn squash is one of those winners.
When I first started playing with this recipe, I wanted to create a casserole that was reminiscent of my mom's chicken and broccoli casserole minus the cans of soup and with spinach instead of broccoli which tends to go a bit mushy. I also wanted to include some of the yummy squash from our farmbox that seems to accumulate on my kitchen counter.
The first rendition of chicken florentine, was…. meh. A bit watery and lacking in flavor. So I decided to up my game and prepare the different components separately before bringing them all together. This takes a teensy bit more time, but I PROMISE this dish is well worth it. Even my kids love it, but I mostly want it all for myself.
Lately I've been a bit obsessed with spinach, and I find it does best in a dish like this if it's blanched, plunged into ice water, and then squeezed to removed the excess liquid. This prevents the dish from being too watery.
While you're roasting the squash, you can layer the casserole and prepare the deliciously savory sauce. This dish can be easily modified if you are grain-free, gluten-free, or paleo with a couple of little tweaks below. You just might want to make double and freeze it the second one for later… it's so darn good.
Chicken Florentine over acorn squash – ingredients
- 1 large acorn squash
- 4 cups cooked chicken (either pull off a roasted chicken or cook up boneless, skinless breasts and/or thighs)
- 1 onion
- 2 cloves garlic
- 2 tablespoons extra virgin olive oil
- 2 pounds fresh spinach
- 2 tablespoons sprouted wheat flour, or use 1 T. arrowroot mixed with 2 T. filtered water
- 3 cups chicken stock
- 3/4 cup white wine
- 1 1/2 cups cream – Dairy-free? …Replace cream with bone broth
- 2 ounces parmesan cheese, optional
- 1 lemon
Chicken Florentine over acorn squash – method
- Bring a large sauce pan half filled with filtered water to a boil. Blanch baby spinach in boiling water for just a few seconds. Drain and plunge spinach in a bowl of ice water. Drain again. Using clean hands, squeeze all excess water out of the spinach. When most of the liquid is removed, break apart the spinach and set aside.
- Preheat oven to 400F. Place acorn squash onto oven grate whole. Bake for 25-30 minutes, or until squash can be easily punctured with a fork. Allow to cool before handling.
- Once squash is cooled, slice in half. Use a large spoon to scoop out and discard the seeds and stringy center. The skin on acorn squash is edible, so it's your choice whether to leave it or remove it now. (I prefer without). Chop squash into 1 inch cubes.
- Turn on oven to preheat broiler.
- Chop cooked chicken into 1 inch cubes. Finely mince onion and garlic.
- In a 9×9 or equivalent casserole dish, layer the cubed squash and then the cubed chicken and finally the cooked spinach.
- Heat olive oil in a large pan over medium high heat, add onion and sauté until the onion begins to soften. Add garlic and saute for another 2 minutes.
If you are using flour: Sprinkle in the sprouted flour and sauté until golden. Slowly add broth (your are making a roux).
If you are using arrowroot + water: Add broth now. Add the slurry after adding the wine and cream below. - When well combined, add white wine and cream (or extra broth). Bring to a boil. Reduce heat and simmer about 10 minutes or until you have a thick creamy sauce.
- Grate optional parmesan cheese. Zest and juice the lemon. Remove sauce from heat once desired thickness has been reached and stir in half of the cheese and all of the lemon zest and juice.
- Pour sauce over squash, chicken, and spinach. Top with remaining parmesan cheese and place dish under broiler for a quick 2-3 minutes just until cheese is melted. Serve hot. Leftovers can be reheated in a pan on the stove.

Where do the 3 cups of chicken stock go? And the first T. of EVOO?
Emily says
Hi Tess – The EVOO and chicken stock all happen in step 7. 🙂

How soft is the acorn squash when you cook it in the oven first? I’d like to roast the cubed acorn squash before adding it to the dish, but I’m wondering if it will be too difficult to cut it when it’s not baked first. Can you bake it to make it easier to peel and cube, then roast it?
Emily says
Hi Yvette, we haven’t tried it that way but don’t see why you couldn’t. Let us know how it turns out if you do. The longer you cook it, the softer it would be. It would probably just add some cooking time to the preparation, though. Hope that helps.
Joanne says
This is amazing!!!! My husband is not a squah or spinach fan but loved this too. Thanks for the great recipe!
Tracey says
Well I really wanted to love this recipe, but it was a total flop. I made it dairy free, which is probably part of the reason it wasn’t great, but the arrowroot powder never made the liquid thicken up, and it was just sooooo runny. Way too much liquid. Also, despite salting in each step, the dish was significantly under seasoned. You didn’t include any seasoning measurements. The real kicker was that it took me 2hrs to make start to finish, and the result was so disappointing!!
Rachel says
I bet this would work great with frozen spinach, too!
Jewel says
What’s a good substitute for the wine?
Emily Bartlett says
Hi Jewel, if you don’t want to use wine, you can use extra chicken broth. It won’t be the same flavor but it will give the right liquid content and it is nutrient dense.

Okay, just made this recipe. It is pretty time consuming although is was cleaning up as I went so the steps were not occurring simultaneously. I struggled to get the sauce thickened. I added more flour which seemed to help. I also only used 1/4 cup of wine. I used Sherry which was strong. Not sure what other types of wine were used. I also broiled it on a lower rack for almost 10 mins since my chicken was cold out of the fridge. It looked and smelled great!
Knowing how healthy this dish is made it worth the time. The consistency of the squash is a hard substitute for pasta lovers. My husband was not a huge fan and I struggled to eat it as left overs. Probably would not make again.
Thank you so much for the recipe though.
