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!

  1. Sauté: Start by sautéing 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 – it makes for awesome flavor!
  2. Slow cook: Next, add your sautéed 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.
  3. 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.

Prep Time: 10 minutes
Cook Time: 3 hours
Total Time: 3 hours 10 minutes
Servings: 6

Ingredients  

  • 1/2 Tablespoon olive oil
  • 1 medium onion, diced
  • 4 large garlic cloves, minced
  • 2 teaspoons ground turmeric
  • 1 teaspoon ground cumin
  • 1 teaspoon chili powder
  • 1/4 teaspoon cayenne pepper
  • 1/4 teaspoon cinnamon
  • 1 teaspoon sea salt
  • 1/2 teaspoon ground black pepper, to taste
  • 1 medium butternut squash, peeled, seeded and chopped (about 5 cups)
  • 4 cups low-sodium vegetable broth
  • 1 – 14 oz can diced tomatoes
  • 1 – 14 oz can light coconut milk
  • 1 cup dried red lentils, rinsed
  • 3 tablespoons tomato paste
  • 2-3 teaspoons apple cider vinegar
  • 1-2 cups chopped spinach, optional
  • chopped cilantro and sliced green onions, for garnish
  • cooked brown rice or quinoa, optional

Instructions 

Slow Cooker:

  • Add oil to a sauce pan or the base of your slow cooker (if it’s stove-top safe) and sauté onion and garlic for 3-5 minutes. Add spices (turmeric, cumin, chili powder, cayenne pepper, cinnamon, sea salt and pepper) and cook for an additional minute.
  • Combine sautéed veggies, butternut squash chunks, veggie broth, tomatoes, coconut milk, lentils, tomato paste and apple cider vinegar together in your slow cooker. Top with lid and cook on high for 3 hours or low for 6 hours, or until lentils and butternut squash are soft and cooked through.
  • Add in spinach, stir and let stew sit for a couple minutes to allow the greens to wilt.
  • Portion stew into bowls, top each bowl with fresh cilantro and green onions before serving. You can also serve the stew over brown rice or quinoa if you’d like.

Stovetop:

  • Add oil to a large stockpot. Once hot, add onion and garlic and sauté for 3-5 minutes. Add spices (turmeric, cumin, chili powder, cayenne pepper, cinnamon, sea salt and pepper) and cook for an additional minute.
  • Add butternut squash chunks, veggie broth, tomatoes, coconut milk, lentils, tomato paste and apple cider vinegar to the pot.
  • Bring mixture to a boil. Once bubbling, reduce heat to medium and simmer the stew uncovered for about 30-35 minutes, stirring occasionally. Once the butternut squash is fork-tender and the lentils are cooked, reduce heat to low.
  • Add in spinach, stir and let stew sit for a couple minutes to allow the greens to wilt.
  • Portion stew into bowls, top each bowl with fresh cilantro and green onions before serving. You can also serve the stew over brown rice or quinoa if you’d like.

Instant Pot:

  • Add oil to the base of your Instant Pot and sauté onion and garlic for 3-5 minutes. Add spices (turmeric, cumin, chili powder, cayenne pepper, cinnamon, sea salt and pepper) and cook for an additional minute before pouring in vegetable broth.
  • Add in butternut squash chunks, tomatoes, coconut milk, lentils, tomato paste and apple cider vinegar. Press Cancel, lock the lid in place and move the pressure valve to Sealing. Select Pressure Cook or Manual; make sure the pressure level is set to High. Set the cooking time for 8 minutes. When pressure cooking is complete, allow the pressure to reduce naturally for 5 minutes, then release the remaining steam by moving the pressure valve to Venting. Press Cancel, then carefully open the pot.
  • Add in spinach, stir and let stew sit for a couple minutes to allow the greens to wilt.
  • Portion stew into bowls, top each bowl with fresh cilantro and green onions before serving. You can also serve the stew over brown rice or quinoa if you’d like.

    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!

    1. 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.

  2. 5 stars
    We really enjoyed this recipe. We used one large sweet potato and one acorn squash because the store didn’t have any butternut. And I substituted collard greens for the spinach. Delicious and we will make it again.

    1. 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!

    1. 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!

    This was insane. Seriously so good. And not ingredients I’ve ever put together. I just reread the recipe and realized I doubled the amount of broth so I’m not sure how that changed things. It’s definitely more broth than I needed lol. But the amount of cayenne and cinnamon were just right. Thank you!

    1. 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!

    1. 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!
