It finally cooled down here in Atlanta and I cannot be happier. As I type this, my windows are open and the crisp morning air feels so good in my face. I love autumn. It feels great to take a break from the 90+ degree weather, put on socks, and wear a cozy sweater. For the last couple of days, I have been in the kitchen testing various recipes for all kinds of baked goods for the upcoming holidays.

My oven has been working overtime and the fridge is full of cookies, tart dough and cake batter. Since sweets do not count for dinner, I needed an easy (mostly hands-off) meal that would balance out all our excess sugar consumption.
And this veggie-packed slow cooker butternut squash lentil stew came to our rescue. It is one of those recipes where you put everything in your slow cooker, forget about it and have dinner ready with minimal effort. Not to mention, it is such a healthy recipe that is made with one of fall’s most popular vegetable: butternut squash.


About this Slow Cooker Butternut Squash Lentil Stew:
Now, I know that I said that you can make this with minimal effort, but I have to mention that the mise-en-place includes quite a bit of chopping. I am fine with chopping onions, carrots, celery, and sweet potatoes, but I would be lying if I were to tell you that I find cutting butternut squash easy. Luckily, our local supermarket sells already cut butternut squash and I found that it is a time saver when I am short on time, especially because you only need 2 cups of butternut squash for this recipe.
Once you have all your ingredients ready, all you have to do is to put everything in your slow cooker, turn it on, and forget about it. It is literally that simple. I cooked it in low-heat setting for five and a half hours. You might think that it is relatively a short amount of time, but even in the low-heat setting my slow cooker cooks faster. Also, I prefer my butternut squash cooked al dente. Though it depends on your crock-pot, I recommend keeping an eye on it after the 5-hour mark. If you are home, feel free to give it a stir a few times during the cooking process.
To make it even more nutritious, right before I was ready to serve, I added a few cups of chopped kale and let the residual heat cook it. In my opinion, it was a great way to brighten the dish and sneak in another superfood.

Regular Green Lentils Versus French le Puy Lentils
I have made this dish both with regular green lentils and French du Puy lentils. I found that le Puy lentils do a better job of retaining their share during the long cooking process. Therefore, if you can get your hands on those, I recommend making this dish using le Puy lentils.
In fact, nowadays, I almost never buy regular lentils anymore for that very reason. I found that while the price is not much different, the end result with French lentils is considerably better. Even with long cooking time, they do not fall apart. Still, if you only have green lentils you could still make this dish, but be aware that if you use regular ones your lentils might not look like mine.

Finally, if you are missing a few ingredients and want to substitute with what you have in your fridge, you could easily do so for this recipe. Perhaps, you could use red potatoes instead of sweet ones or even substitute butternut squash with pumpkin or acorn squash. If you don’t have kale add in spinach or both. Seriously, the sky is the limit. I promise you, this vegan autumn stew is not only a great way to feed your family, but also to clean out your fridge.

Hi, I have just just put the lid on my slow cooker and am looking forward to the finish! One question. I make a crock pot meal like this on the weekend for my meals for the week ahead. How would you suggest I handle the kale/vinegar part on a daily basis? Thank you!
Aysegul Sanford
Hi there..
So happy to hear that you made it. I hope you like it as much as we do.
In terms of the kale and vinegar..
If you plan on serving small portions, you can heat up your soup and add a small amount of vinegar right before serving. You can julienne a few leaves of kale and then add that in and give it a mix while your soup is still hot.
If you are serving it to a crowd (4 people or more), you can warm it up in a large pan and once it comes to a gentle boil you can add in the kale and give it a mix to soften. Then right before serving, you can add in the vinegar.
I hope this helps. I am always here if you have any more questions. Cheers!

Yet another wonderful way to make butternut squash. Great recipe!
Aysegul Sanford
I know, right? Butternut squash stews never disappoint.
Laura Espitia
I made this a few days ago. I was a little suspicious that it could be so healthy and still be tasty but it was ABSOLUTELY DELICIOUS! The coriander and cumin really did their job. My roommates came home asking what that delicious smell was. It was filling and flavorful. The kale added a nice change in texture as it gives you something to bite into. I will be making this again…. and again. Thanks for sharing!
Aysegul Sanford
This is music to my ears Laura. Tis the season for all the squash. I should put it in our weekly menu as well.
Thanks so much for coming back and leaving a comment.
Cheers!

Hello, this may be a dumb question, but is the butternut squash supposed to be already cooked?
Aysegul Sanford
Hi Sally..
Sure. There is no such thing like dumb question. I am glad to help.
No, you do not need to cook the butternut squash. You put everything in the slow cooker altogether.
I would recommend keeping a close eye on it in the last hour of cooking as the butternut squash might get mushy if cooked too long. I like mine cooked “al dante”, but if you like yours cooked fully adjust the timing accordingly. I would give it a stir and taste one of the butternut squash cubes to check the doneness.
If you have any more questions please do not hesitate to write to me. I am home all day and would be more than happy to help in any way I can.
Best,
Aysegul
