I just made a Vegan Fall Soup that’s thick, protein-packed with lentils, and so filling you can skip the side dish.

Jump to Recipe

I’m obsessed with this pumpkin lentil soup because it actually tastes like real food, not mush. I love the way pumpkin puree and red lentils make it thick and totally satisfying, plus it hits protein and comfort points in one bowl.

And the spices sing without trying too hard. This sits squarely in my rotation of Healthy Vegan Pumpkin Recipes and doubles as my go-to Vegan Fall Soup when nights get long and dinner needs to be simple but not boring.

Seriously, spoonful after spoonful. I serve it with a squeeze of lemon and call it dinner every single time.

How to Make this

Print Recipe (No Advertisments)

1. Heat a large pot over medium heat and add a splash of water or a tiny bit of oil if you like, then sauté the diced onion, carrots and celery until the onion is soft and starting to brown, about 6 to 8 minutes; stir often so the veg dont stick.

2. Add the minced garlic, cumin, smoked paprika, ground ginger and optional cayenne, cook for 30 to 60 seconds until fragrant, then scrape up any browned bits from the bottom of the pot.

3. Stir in the rinsed red lentils, pumpkin puree, vegetable broth and 1 cup water; mix well so the pumpkin is evenly distributed.

4. Bring the soup to a gentle boil, then reduce heat to a simmer; cover and cook until lentils are tender, about 12 to 15 minutes — check and stir occasionally to prevent sticking.

5. If the soup is too thick for your taste add more water or broth a splash at a time until you reach the consistency you like.

6. Use an immersion blender to partially puree the soup right in the pot for a creamy but slightly chunky texture, or transfer half or all to a blender in batches and pulse until smooth; be careful with hot liquid.

7. Return the soup to low heat if needed, stir in the chopped kale or baby spinach and cook just until wilted, about 2 to 3 minutes.

8. Season with sea salt, freshly ground black pepper and the lemon juice or apple cider vinegar; taste and adjust salt, acidity or cayenne as needed.

9. Remove from heat and let rest a few minutes so flavors meld; thin with more water or broth if you want it lighter.

10. Serve hot, garnish with chopped parsley or cilantro if using, and enjoy — leftovers keep well in the fridge for 3 to 4 days and reheat nicely with a splash of water.

6. Can opener — for the pumpkin puree can
7. Fine mesh strainer or colander — to rinse the red lentils

9. Soup ladle and bowls — for serving, plus a small spoon for tasting and adjusting seasoning

FAQ

Q: Can I use brown or green lentils instead of red lentils?

A: You can, but cooking times will change. Brown or green lentils hold their shape and need about 25 to 30 minutes, while red lentils break down in 15 to 20 minutes and make the soup creamy. If using brown or green, simmer longer and add a bit more liquid.

Q: Is canned pumpkin the same as pumpkin pie filling?

A: No. Use plain pumpkin puree from a can, not pumpkin pie filling which has sugar and spices already added. Pie filling will mess with the soup's flavor.

Q: How can I make the soup smoother or chunkier?

A: For smooth, use an immersion blender right in the pot or transfer batches to a blender and pulse until you like the texture. For chunkier, just mash a few lentils with the back of a spoon and leave the rest whole.

Q: Can I freeze this soup?

A: Yes. Cool completely, then freeze in airtight containers for up to 3 months. Thaw in the fridge overnight and reheat gently on the stove. Texture might change slightly, but flavor stays great.

Q: How do I adjust the spice level for kids or picky eaters?

A: Omit the cayenne and reduce smoked paprika if needed. Add a squeeze of lemon or a splash of apple cider vinegar at the end to brighten without adding heat. You can always add more spice later.

Q: Can I swap the kale or spinach for another green?

A: Sure. Chard or collard greens work fine, but tougher greens like collards should be chopped smaller and added earlier so they soften. Baby greens can be stirred in at the end so they dont overcook.

Cozy Pumpkin Lentil Soup (vegan, Gluten Free, Wfpb) Recipe Substitutions and Variations

Red lentils: swap for yellow split peas or orange/masoor lentils (they cook about the same), or use 3/4 cup brown lentils if you don’t mind a firmer texture and longer cook time.
Pumpkin puree: use canned sweet potato or butternut squash puree, or mash roasted carrots for a lighter flavor — they give the same creamy body.
Kale or baby spinach: replace with Swiss chard, collard greens, or frozen chopped spinach (add a minute or two more if using hearty greens).
Lemon juice / apple cider vinegar: swap with white wine vinegar, rice vinegar, or a splash of orange juice for a sweeter bright note.

Pro Tips

– Cook the onion, carrots and celery low and slow until they get some color; those brown bits actually add a lot of flavor. If they start to stick, splash in a little water or broth and scrape the bottom with your spoon. Don’t rush this part, you want depth not just soft veg.

– Rinse the red lentils really well and check them for little stones or bits before adding. They cook fast so keep an eye on simmer time, and if the soup looks too thick later add warm broth or water instead of cold so it doesn’t shock the pot.

– When you blend, cool it for a minute and hold the lid slightly ajar with a towel so steam can escape. Blending hot liquid can burst lids and make a mess, and pulsing instead of full-on blending keeps some nice texture if you like a heartier soup.

– Finish with the acid and greens at the end. A squeeze of lemon or a splash of vinegar brightens the whole bowl, and stirring in the kale or spinach off the heat keeps them vibrant. Taste after adding acid and then adjust salt, because acid makes saltiness pop more.
