This butternut squash lentil stew features red lentils, coconut milk and a robust blend of spices. Recipe has instructions for the slow cooker or stovetop.
It’s the perfect time of year for this cozy stew. It feels like spring should be right around the corner, but my guess is that half of the U.S. is still covered in snow and doesn’t feel like spring is anywhere near. So for those of you battling cold temps and wanting a simple dinner that will warm you up from the inside out, this stew is for you.

This veggie-packed stew is inspired by my butternut squash and turkey chili, which is cooked in the Instant Pot. I LOVE this chili so much, but recently wanted to try a completely vegetarian version with extra red lentils and this was the result. It’s so warm, comforting and amazing filling for a vegetarian meal. I love the combo of red lentils with butternut squash, and the unique combo of spices in this soup make it so delicious. I can’t wait for you to try it!
I know cooking lentils can be a little intimidating, but this method could not be simpler. I’ll answer some FAQs below, but don’t hesitate to leave a comment if you have any additional questions!
Can You Put Dried Lentils in a Slow Cooker?
Yes! You can put dried, uncooked lentils in a slow cooker with liquid and they will cook through. For this recipe, you’ll put all of your ingredients for the stew in the slow cooker and it’ll work its magic.
Do You Have to Soak Lentils Before Slow Cooking?
Nope! Lentils are the one of the only dry beans that you don’t need to soak before cooking. You can soak them if you want to speed up the cooking process, but it’s not necessary. On thing to note: You should always rinse your lentils before cooking just to clean them off and remove any stones, debris or shriveled lentils. Once rinsed and sorted, drain and use as directed in the recipe.
Can You Overcook Lentils?
Yes, you can overcook lentils. It’s not as easy to notice with red lentils because they’re softer than green or brown lentils, but when lentils are overcooked they end up getting super soft and mushy. Follow the directions in this recipe to make sure you don’t end up with mushy lentils from overcooking.
How to make Vegetarian Slow Cooker Stew
The ingredient list for this recipe might look long and intimidating, but almost half of the ingredients are spices you probably already have in your spice cabinet, so don’t stress!
- Sautรฉ: Start by sautรฉing the chopped onion and garlic in a saucepan (or your slow cooker if it’s stovetop safe!) and add in the spices. I love seasoning multiple layers of a dish โ it makes for awesome flavor!
- Slow cook: Next, add your sautรฉed onion and garlic to the slow cooker along with the butternut squash, broth, tomatoes, coconut milk, lentils, tomato paste, and apple cider vinegar. Cover and cook on high for 3 hours or on low for 6. You’ll know it’s ready when the lentils and butternut squash are soft and cooked through. Feel free to taste test to make sure.
- Enjoy: Once the stew is cooked through, you’ll stir in your spinach (if using) and let it sit for a couple of minutes so the greens get a little wilted. Then it’s ready to serve! Enjoy on its own or serve over brown rice or quinoa if you’d like.

I want to try this but I cannot have coconut products. Is there an alternative that would work?
Hi Jenny – I haven’t tried it, but I bet any milk would work, you just wouldn’t get that coconut flavor. Let me know if you give this a try!
This was insane. Seriously so good. And not ingredients Iโve ever put together. I just reread the recipe and realized I doubled the amount of broth so Iโm not sure how that changed things. Itโs definitely more broth than I needed lol. But the amount of cayenne and cinnamon were just right. Thank you!
Sounds amazing, Amy! I am so glad you gave this recipe a try and it is a hit for you. It was probably more soupy than a stew consistency but that is probably the only aspect that changed. Thank you for your review + star rating, I really appreciate it!
Absolutely delicious thank you
Quick question will it freeze? Thanks again
Yay! I am so glad that you are enjoying this recipe, Martha. I am not sure this would freeze well, unless you added in the lentils after thawing. I am afraid they would get too mushy and the texture of the soup would be off. Thank you so much for your review + star rating, I really appreciate it!
We really enjoyed this recipe. We used one large sweet potato and one acorn squash because the store didnโt have any butternut. And I substituted collard greens for the spinach. Delicious and we will make it again.
Excellent! This sounds absolutely delicious, Mary! I am glad to hear that you are loving this recipe, thank you for your review + star rating, I so appreciate it!
I made this stew and it smells yummy. But why is mine so much thinner and chunkier than yours?
Hmmm, did your soup thicken up? I’m wondering if your lentils were fully cooked?
I had to cook it for a total of 4 hours in the slow cooker. thanks!
This was amazing! So comforting. This soup is hearty, warming, subtly sweet and subtly spicy. Everything I want in a winter soup. I will look forward to eating it cold for lunch tomorrow with a swirl or garlic yogurt and more fresh cilantro. Thank you!
Yum! I am pumped to hear that you are loving this recipe, Billie. Thank you so much for sharing your review & star rating, I so appreciate it.
