- 1 1/2 cups sweet potatoes, peeled and cut into 1/2 inch cubes
- 1 cup gold potatoes, peeled and cut into 1/2 inch cubes
- 1 cup carrots, thinly sliced
- 1 cup celery, thinly sliced
- 1 small sweet onion, finely diced
- 4 garlic cloves, minced
- 1 cup green lentils, rinsed
- 4 cups vegetable broth
- 1 teaspoon poultry seasoning

- 1/4 cup olive oil
- 1 tablespoon fresh lemon juice
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 tablespoons chopped fresh parsley

Step-by-Step Instructions for the Best Slow Cooker Lentil and Sweet Potato Soup
I really love how simple the prep is for this soup. It’s one of those meals you can honestly throw together in the morning before heading out the door, and it’s ready when you get home. Trust me, the smell alone will make you happy!
Step 1: Alright, get your slow cooker ready! You’re going to dump in the sweet potatoes, gold potatoes, carrots, celery, that finely diced sweet onion, and all your minced garlic. Then, add in your rinsed green lentils. Don’t forget the vegetable broth, poultry seasoning, thyme, salt, and black pepper. Give it all a really good stir so everything is nicely combined and happy together.
Step 2: Once everything is mixed up, just pop the lid on your slow cooker. You can cook it on high for about 5 to 6 hours, or if you have a little more time, set it to low for 7 to 8 hours. Either way, you want to cook it until those lentils and potatoes are super tender and fall apart easily when you poke them with a spoon.
Step 3: Okay, here’s the secret to that amazing creamy texture without any dairy! Carefully scoop out about one-third of the soup into a blender. Be careful, it’s hot! Add the olive oil to the blender with the soup. Blend it on a low speed until it’s smooth and creamy. You don’t want to over-blend, just get it nice and smooth.
Step 4: Pour that lovely, creamy blended soup back into the slow cooker with the rest of the soup. Give it a good stir so it all mixes together and you get that perfect, slightly thickened consistency. It’s like magic, but way tastier!
Step 5: Stir in the fresh lemon juice – this really brightens up all those deep flavors – and the chopped fresh parsley for that pop of green and fresh taste. Give it one last taste and add a little more salt or pepper if you think it needs it. Sometimes my veggies need a little extra love!
Step 6: Ladle this gorgeous, hearty soup into bowls. Top it off with some grated parmesan cheese. It sounds simple, but that salty, cheesy topping really rounds everything out.

Serving Suggestions for Your Hearty Lentil and Sweet Potato Soup
This soup is wonderfully satisfying on its own, but sometimes you just want a little *extra* something, right? Here are a few things I love to serve alongside it that just make the meal sing!
Crusty Bread: You absolutely NEED something to soak up every last drop of this delicious soup! A good sourdough or a simple baguette is perfect.
A Dollop of Greek Yogurt or Sour Cream: If you’re not adding parmesan, a little swirl of plain Greek yogurt or sour cream adds a lovely tangy creaminess. It’s also a great way to cool down a super hot spoonful for little ones.
A Simple Side Salad: For a lighter touch, a crisp green salad with a light vinaigrette is refreshing. Or, if you’re feeling a bit more adventurous, some Garlic Parmesan Roasted Broccoli is always a winner in my house!
Avocado Slices or Guacamole: Talk about a flavor boost! Creamy avocado or a small side of easy guacamole adds healthy fats and a delicious richness that pairs surprisingly well with the earthy lentils and sweet potatoes.
Storing and Reheating Your Slow Cooker Lentil and Sweet Potato Soup
This soup is honestly a meal-prepper’s dream! It stores and reheats like an absolute champ, which is why I always make a double batch. It’s so satisfying to know you have healthy, delicious lunches ready to go for the week.
Once your soup has cooled a bit, you can stash it in airtight containers in the fridge. It’ll stay delicious for about 4 days. Honestly, it tastes even better the next day, as all those flavors get to mingle and get to know each other better!
When you’re ready to reheat, I find the stovetop is your best bet for getting that lovely texture back. Just pour the soup into a pot over medium-low heat and stir occasionally until it’s all heated through. If you’re in a super hurry, the microwave works too – just use a microwave-safe bowl and heat in 1-2 minute intervals, stirring in between, until it’s piping hot. You might need to add a tiny splash of broth or water if it’s gotten a bit thick.
This soup is also fantastic for freezing! It freezes beautifully for up to 3 months. Just pop it in freezer-safe containers, leaving a little headspace for expansion. Having this on hand is like giving yourself a hug for future busy days.

Frequently Asked Questions About This Lentil and Sweet Potato Soup
Can I use different types of lentils?
You sure can! While I really love the creaminess green lentils give this soup, you can totally swap them out for brown lentils. They’ll cook up pretty similarly. Red lentils, though, tend to break down much faster and can make the soup a bit *too* mushy, so I’d stick with green or brown if you can!
How can I make this soup thicker or thinner?
If your soup is too thick after blending, just stir in a little more vegetable broth or even some water, a tablespoon at a time, until it reaches your desired consistency. On the flip side, if it seems too thin? That’s where the blending trick comes in handy again! You can either re-blend a bit more of the soup or, if you have extra cooked lentils or potatoes on hand, you can mash some up and stir them in. It thickens things right up!
Is this soup freezer-friendly?
Oh, absolutely! This soup freezes like a dream. I often make a double batch just for this reason. Let it cool completely, then portion it into freezer-safe containers or bags. It’ll keep beautifully for up to 3 months. Just thaw it in the fridge overnight and then reheat on the stovetop or in the microwave. It’s perfect for those days you just need a quick and healthy meal without any effort!
