This is one of my favourite simple soups to make when the weather is cool. And this Super Curried Red Lentil and Sweet Potato Soup couldn’t be easier to make!
My Super Curried Red Lentil and Sweet Potato Soup made its debut at my fall-inspired Everyday Superfoods cooking workshop last November and instantly gained a throng of fans.
Well, at least one or two of them.
This hearty, nourishing soup has now become a seasonal staple in my kitchen, and I’m excited to share the recipe more widely today.

Normally this recipe sells as part of my exclusive Everyday Superfoods recipe pack, but today it’s all yours just for visiting and celebrating the arrival of spring with me! I find this soup to be the perfect transitional dish.
It’s warming and comforting, yet bright and veggie-packed to welcome the new season.
Why Make this Curried Red Lentil and Sweet Potato Soup
What makes this Super Curried Red Lentil and Sweet Potato Soup so special? For starters, the combination of earthy red lentils and hearty sweet potatoes is an absolute flavour explosion. The curry powder, ginger, and aromatic spices lend a lovely depth of flavour.
A splash of coconut milk at the end makes the whole thing silky smooth and ultra-satisfying.
My Super Curried Red Lentil and Sweet Potato Soup makes for a lightning-fast lunch or supper and is equal parts warming and spicy.
Beyond the delicious taste, this curried soup is also a nourishing and well-balanced meal. Red lentils are a fantastic source of plant-based protein, fibre, and complex carbohydrates to keep you feeling full and satisfied. Sweet potatoes are packed with beta-carotene, vitamin C, and other antioxidants. And the blend of warming spices provide anti-inflammatory benefits, making this soup a true “superfood” in a bowl.
The best part? If you have red lentils and sweet potatoes, you can make this soup without a trip to the grocery store. It’s the ultimate pantry-friendly, budget-friendly meal. And the spices are completely interchangeable, so you can customize it to suit your personal taste preferences.
Like with all of my recipes, don’t hesitate to make this soup your way, according to your rules.
Gaining culinary confidence is all about trying new things depending on what you feel like at any given time.

Ingredient Details of this Super Curried Red Lentil and Sweet Potato Soup
Red lentils are one of my all-time favorite ingredients to work with. Unlike their green or brown counterparts, red lentils have a short cooking time. They break down into a lovely, creamy texture, which makes them perfect for soups and stews. They’re also packed with protein, fibre, folate, and other essential vitamins and minerals.
When it comes to cooking red lentils, the key is to not overcook them. They can go from perfectly tender to mush in the blink of an eye. I recommend simmering them for 15-20 minutes, stirring occasionally, until they’re soft but still holding their shape. You can always add a splash of broth or water if they become too thick.
Sweet potatoes are the unsung heroes of the vegetable world. Not only are they delicious, but they’re also incredibly nutritious. They’re an excellent source of beta-carotene, which our bodies convert into vitamin A. This is needed for healthy vision, skin, and immune function. They also contain significant amounts of vitamin C, manganese, and various antioxidants.
The spice blend in this soup is what really makes it sing. Play around with different curry powder blends, or even use individual spices like garam masala, chili powder, or ground coriander.
The key is to toast the spices briefly in the pot before adding the other ingredients. This helps to release their essential oils and deepens their flavour. And don’t be afraid to adjust the amounts to suit your personal taste preferences.
Once the lentils and sweet potatoes are simmered to perfection, I like to stir coconut milk in at the end. This adds a delightful creaminess and richness to the soup, without weighing it down. You can use full-fat or light coconut milk, depending on your needs, but of course I prefer full-fat.
I also like to finish the soup with fresh cilantro or parsley, which gives it a lovely pop of colour. And don’t forget the squeeze of fresh lime juice – it really makes everything come alive.
