Curry Sweet Potato + Red Lentil Soup
I ran across this recipe from BBC Good Food with (mostly) great reviews and couldn’t pass up adapting it to fit into the recipe collection. The ingredient list is fairly simple and straight forward. What I really love about this recipe is the addition if a green apple and toasting the curry.
I didn’t change the original recipe too much, just a few tweaks to make it vegan and make sure it isn’t overly sweet.
A few of the changes I’ve made include:
- Narrowing down the apple choice. The original recipe calls for an ‘eating’ apple, but after reading reviews that the soup was too sweet, I decided to narrow it down and go with a green apple. The tartness helps cut into the sweetness of the potatoes.
- Also, some didn’t like the lime juice, but I loved it here. It will also help cut the sweetness, as well as add a little brightness. I would suggest starting with ½ of the lime juice, and adding the other half if needed. I didn’t find the soup to be too sweet at all with the green apple and lime juice, just a nice balance of sweet and savory.
- For the milk, feel free to change it up using either coconut milk (light, full-fat, or cream), or your favorite non-dairy unsweetened milk. I used coconut cream here, and needless to say it was delicious!
How To Make Curry Sweet Potato + Red Lentil Soup
- Cube, dice and mince your ingredients.
- Cook soup in a large dutch oven or pot – you’ll want to use at least a 5 quart pot.
- Once soup is done simmering, you can either eat it as is or puree it using an immersion blender. The soup on the left has just finished simmering, and can be eaten as is if you like. At this point the soup is a mustard color, but once pureed the soup will take on an amber glow (shown on the right).
- If you prefer your soup in the middle of pureed and chunky, you can always roughly puree the soup, which is what I usually do. I love finding a few chunks of goodness here and there!
- Serve with a spoonful of ultra-creamy coconut cream and freshly chopped cilantro over top. And for those who like a little heat, add a sprinkle of red pepper flakes and/or jalapeno slices to get your fix.
Both wholesome and nutrient dense, I hope you enjoy this soup as much as I did!
How Long Will Leftovers Keep?
Leftovers will keep for 5 – 6 days in the refrigerator, stored in a covered container. Simply re-warm on the stovetop or the microwave. It makes a great meal prep for the week with homemade no knead bread or Naan on the side for soaking up the juices.
Can You Freeze Sweet Potato + Red Lentil Soup?
Yes, it freezes well for up to 2 months! My favorite way to freeze this soup is in individual small containers that are freezer safe. That way whenever I want to cozy up with a bowl of warm soup I can just pull it from the freezer and warm it up. You can also freeze larger portions in large ziplock bags or containers.
Adjusting For Dietary Restrictions
- Grain-Free: Omit the lentils and reduce the liquids to 3 – 4 cups to make this recipe grain-free, adding more liquids as needed.
- Gluten Free: This soup is already gluten free!
- Low-Fat: Instead of using coconut milk, opt for unsweetened plant milk.
- Oil-Free: When sauting the onions and garlic, be sure to use water or vegetable broth instead of oil to make this recipe oil-free. The broth will yield the most flavor, but water is great too and what I usually use.
