Ingredients needed for making sweet potato curry:
- Red Thai Curry Paste elevates the flavor of this vegan sweet potato curry without having to hunt for expensive exotic ingredients. Check the label to make sure it’s vegan.
- Coconut milk makes this extra luscious – you could also stir in some coconut cream right in the end to add some extra richness.
- Red lentils are high in protein and the fastest cooking lentils out there. In general, they should take only about 15 – 25 minutes to cook. Keep in mind that they don’t hold their shape like other lentils do and tend to get mushy. This makes them perfect for things like red lentil dal, but also for thickening this delicious curry without having to add any cornstarch.
- Freshly grated ginger root adds a bit of heat and makes this extra warming while adding some serious health benefits.
- Lime zest and freshly squeezed lime juice brighten and lighten this vegan curry up and help balance out the sweetness and richness of coconut milk and sweet potatoes. You could use lemon instead if you cannot find lime.
- I love using Thai basil to make this curry really authentic tasting. It has a hint of licorice taste to it that is quite different from sweet basil. If you can’t find it, by all means, use regular sweet basil.
Tips and Variations for making Red Lentil Sweet Potato Soup:
- Add some smooth peanut butter and curry powder for a rich and creamy Massaman-style soup.
- Not a fan of lentils? Add 10 ounces (284g) cubed firm or extra-firm tofu instead of cooked lentils for a boost of plant-based protein.
- In fall, you could use squash or pumpkin instead of sweet potatoes.
- To up the protein content even more, add a can of chickpeas.
- Feel free to stir in some frozen peas or some fresh spinach right in the end for some more color.

How to make Vegan Red Lentil Sweet Potato Curry:
Combine the lentils with 2½ cups (600ml) of the water in a small saucepan over medium heat. Cook the lentils for 13 to 15 minutes, or until they are al dente, stirring once halfway through the cooking time. Drain the lentils and set aside.
Meanwhile, heat the oil in a large saucepan over medium heat.

Meanwhile, heat the oil in a large saucepan over medium heat. Add the onion, garlic, and a pinch salt and cook until the onion is translucent about 4 minutes.

Add the ginger and red curry paste and stir to combine. Cook the mixture for 1 to 2 minutes, until the paste is fragrant. Add the veggies and mix well.

Add the milk, remaining ¾ cup (180ml) water, salt, sugar, cayenne, lime zest, and lime juice and stir to combine. Cover and cook for 10 mins or until sweet potatoes are cooked.
Add the cooked lentils and bring the mixture to a rolling boil. Taste and adjust the seasonings. Reduce the heat to low. Add the Thai basil. Cover the saucepan and simmer for a few minutes, until the vegetables are cooked through and the flavors meld. Garnish with the basil and lime wedges.

What to serve with this vegan coconut sweet potato curry?
You could eat this as is, like you’d eat soup or stew. But I also like serving this Vegan Thai curry with plain Basmati rice or a bowl of fragrant seasoned rice like this turmeric lemon rice. If you want to take this into a Thai-Indian fusion direction, let me tell you that this also pairs extremely well with vegan flatbread of choice.
How to store this curry:
Leftovers can be stored in an airtight container in the refrigerator for up to 5 days. You can also freeze this for up to 3 months.

This was delicious. I topped it with green and avocado instead of basil. Thank you!
Awesome
So delicious!! Will make this recipe over and over again!
thanks for popping in ♡
Hi, great and tasty recipe…but mine turned out a bit too liquid. I think next time I won’t be putting water after the coconut milk. Otherwise turned out amazing! Thank you!
thank you
I made this and loved it! I have attempted many curry recipes and this is hands down the best. I’d like to try your suggestion of peanut butter and curry for a massaman style dish. How much would you recommend of each?
2 tbsp pb and atleast 1/2 tsp tamarind pasta if you have it. 1/2 tsp or more spices
Thanks! I don’t have tamarind but have curry and garam masala
Use curry powder then. Taste and add more as needed jn the end
Super delicious! I’m devouring it right now. There were veggies I needed to use so along with the sweet potatoes I added a carrot, a bit of radicchio and bunches of stalks-and-a-few-leaves of chard and kale, also bits of old bread that wasn’t great to eat as is. Didn’t increase the seasonings and good for that because the spiciness is perfect this way. I Added a bit of cashew butter for ceeaminess. I’ll make this again.
I made this tonight with just sweet potatoes and red bell pepper. It’s delicious and I’ll definitely be making it again.
Great recipe! I didn’t have any red curry paste but substituted with some spices and it was still so good. Thanks!
We’ve made this at least 5 times during quarantine, so easy and delicious, plus flexible with whatever veggies we are able to get from the store. Thanks Richa!!
wow – 5 times! perfect.
This was delicious! I left out the red curry paste until the end so that I could give a less spicy version to my kids. They are slurping it up as I write this. I sauteed the curry paste in a separate pan with a little of the sauce and then added it into the main pot after I’d fed the kids. I love Maesri or May Ploy curry paste. I used to use Thai Kitchen but the other brands are way better and you don’t need to use as much. I’ll definitely make this again!
Awesome!
Another great recipe from Vegan Richa! We made ours with red bell pepper, sweet potato, and zucchini. My husband thought the spice level was perfect, while I added rice to mine to cut the spice a little. Will add this recipe into our regular rotation!
