Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

olive oil
onion, diced
carrot, diced
garlic, minced
vegetable or chicken stock / broth
red (or your preferred) lentils, rinsed and sorted
corn (optional — whole‑kernel or canned)
ground cumin
curry powder (optional)
pinch of saffron (optional)
pinch of cayenne (optional — for a bit of heat)
lemon zest and juice
salt and black pepper

Directions

Heat the olive oil in a large pot over medium‑high heat. Add the diced onion and carrot; sauté until the onion becomes soft and translucent (about 5 minutes). Add the minced garlic and cook for another minute until fragrant.
Stir in the broth/stock, lentils, corn (if using), cumin, curry powder, and, if using, saffron and cayenne. Bring the mixture to a simmer. Cover and cook for about 15 minutes, or until the lentils are tender.
(Optional) For a creamier texture, use a hand blender or transfer in batches to a blender and purée until you reach the desired consistency.
Stir in the lemon zest and juice. Taste, then season with salt and black pepper as needed.
Serve warm. If you like, garnish with a slice of lemon for an extra zing.

Servings and timing

Serves: 4
Prep time: ~10 minutes
Cook time: ~25 minutes
Total time: ~35 minutes

Variations

Omit the corn for a more traditional, simpler lentil soup.
Add leafy greens (e.g. spinach or kale) in the last few minutes of cooking for extra nutrients and texture.
For a richer, creamier soup, purée the whole soup and optionally stir in a splash of cream or yogurt (or plant‑based equivalent).
Adjust spices: more cayenne for heat, add herbs like parsley, cilantro, or dill for freshness, or swap curry powder for turmeric or smoked paprika depending on your taste.

Storage/Reheating

Let the soup cool, then store in an airtight container in the refrigerator for up to 3–4 days. To reheat, warm gently on the stovetop over low heat (adding a little extra water or broth if it’s too thick). You can also freeze portions for up to 2–3 months — thaw overnight in the fridge before reheating.

FAQs

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

Yes — green or brown lentils work fine. They hold their shape better and give more texture, though they may require slightly longer cooking. If you prefer a smoother soup, red lentils are ideal because they break down more easily.

Do I need to soak the lentils before cooking?

No — lentils cook relatively quickly and don’t need prior soaking. Rinse them thoroughly before using.

Can I skip the corn?

Yes — the corn is optional and mainly adds a subtle sweetness and extra texture. The soup will still taste great without it.

What if I don’t have curry powder or saffron?

That’s fine: omit the curry powder and saffron. You can rely on cumin and fresh lemon for flavor, or substitute with spices you have on hand (like turmeric, smoked paprika, or chili flakes).

Can I make this soup vegan?

Absolutely — use vegetable stock and skip any dairy-based toppings. The recipe as written is vegan-friendly.

How can I make the soup thicker or creamier?

Use a hand blender or regular blender to purée the soup (all or part of it) after cooking. For extra creaminess, stir in a dollop of plain yogurt or coconut milk after blending.

Can I add vegetables like potatoes, spinach, or kale?

Yes — adding leafy greens such as spinach or kale near the end of cooking is a great way to boost nutrition. Potatoes, sweet potatoes, or other vegetables can also be added early on for more heartiness.

Is the lemon essential?

Lemon (juice and zest) is key to giving the soup its characteristic fresh, bright flavor. You could reduce the amount for a milder taste, but omitting it altogether will change the soup’s feel quite a bit.

How long does leftover soup stay good in the fridge?

Stored in a sealed container, the soup should stay fresh for 3–4 days. For longer storage, freeze in portions.

Can I freeze the soup?

Yes — cool completely, then freeze in airtight or freezer‑safe containers. The soup should keep well for up to 2–3 months. Thaw overnight in the fridge before reheating.
