Ingredients You’ll Need
Here’s everything you will need to make this hearty soup, plus substitution ideas for ‘your’ perfect vegan lentil soup.
- Lentils. These are the main protein source in this curry soup. You can use either brown or green lentils in the recipe. If using green lentils, you’ll need to add a few minutes of cooking time as noted in the recipe card below.
- Mirepoix. The usual mix of onion, carrot and celery that makes a great flavor base, adds color and texture.
- Garlic. If you don’t have fresh garlic on hand, substitute with 1 teaspoon garlic powder.
- Potatoes. Use waxy potatoes such as red, white or Yukon gold, as they hold their shape nicely when simmered. I used baby potatoes here, but regular size is great too.
- Green Beans. Use fresh or frozen.
- Tomatoes. Use canned for convenience or fresh if roma tomatoes are in season.
- Greens. I used a packaged baby kale & spinach mix, but you can use whatever greens you like – spinach, rainbow chard, beet greens or kale.
- Spices. Together the paprika, cumin and curry add a deep warming flavor that I have fallen in love with. This is a delicious combination and I know you’ll love it too! For variation, I think thyme would be a great substitution for the cumin and curry.
- Parsley & Lemon. Adds a finishing touch, adding brightness and freshness.
How To Make Vegan Lentil Soup
Vegan lentil soup can be made on the stovetop, in a slow-cooker or Instant Pot with just a few simple adjustments.
Here’s a quick look at your options:
- Stovetop: Using a large pot, you’ll simply saute the onion, carrots, celery and garlic, then add the remaining ingredients, except the greens, and simmer for about 30 – 35 minutes. Towards the end of cooking add in the greens and enjoy!
- Instant Pot: Add the ingredients, except the greens, to the bowl of your pressure cooker. Place the lid on the Instant Pot and set the release valve to the SEALED position. Press the MANUAL button and set the timer at 15 minutes. Once finished, set valve to quick release or let it release pressure on its own (takes about 20 minutes). Remove lid, stir in the greens.
- Slow Cooker: This is the set it and forget it method! Simply add the ingredients, except the greens, to the crock pot bowl. Cover with lid and set on HIGH for 4 – 5 hours or LOW for 8 – 10 hours. Add greens, let them wilt and serve!
Serving Suggestions
I like to garnish this lentil soup with parsley, a squeeze of lemon and twist of fresh cracked pepper. Here are a few of my favorite sides:
- Bread: Serve with homemade Artisan Bread, Vegan Cornbread or Vegan Naan for dipping and swiping.
- Sandwiches: Serve with this Favorite Vegetable Sandwich, Roasted Red Pepper Sandwich, or Grilled Hummus Sandwich with Sauteed Onion Tomato & Arugula, Sandwich.
- Salad: Pair with Green Salad + Tahini Dressing (or use this Healthy Flax & Evo Balsamic Vinaigrette), Vegan Caesar Salad, or leafy green salad with Vegan Ranch.
How To Store Leftovers
- Refrigerator: Leftovers will keep for 5 – 6 days in the refrigerator, stored in a covered container. It makes for
- Reheat: Simply re-warm on the stovetop over low heat until warmed through. Alternatively, reheat in the microwave using 30 – 60 second intervals, stirring after each, until warm.
- Make ahead: This soup is great for meal prepping for the week and tastes even better the next day.
Can Lentil Soup Be Frozen?
Lentil soup freezes beautifully for up to 2 – 3 months! To freeze, let cool completely and store in freezer safe containers (affiliate link), leaving 1/2 inch head space for expansion. Let thaw before reheating. You can also freeze larger portions in large ziplock bags.

I made this in our Insta pot today. I didn’t have tomatoes on hand but had some frozen butternut squash in the freezer. I used the squash in place of the tomatoes and it adds a nice, sweet flavor to it. I’m definitely going to make this again!
Kathie says
The stovetop directions do not say when to add the 6 cups of water/broth. This should be done in step 2, when the lentils, tomatoes, green beans, and spices are added, correct?
Thanks!
Julie | The Simple Veganista says
Yes, you are correct – add the water with the lentils, tomaotes, etc. Not sure how I missed that, but thank you so much for pointing it out. I’ve added it to the instructions. Enjoy the soup and do let us know how it goes for you! Cheers :)

Really delicious, nourishing, and cozy dinner! I love how many vegetables are in this, and the ease of a one pot meal can’t be beat. A few things of note– I made this in the slow cooker and it took 4-4.5 hours to really soften the celery and potatoes. I noticed that the directions mentioned Bay leaves but they weren’t included on the ingredients list. I threw in 2 leaves and worked out nicely :) and lastly, I think I had some really juicy lemons because the lemon flavor was strong in this dish. Depending on how much juice my lemons yield next time, I might just stick with one :) My family really enjoyed this meal! Thank you!
