The backstory.

This is the soup I make when I need dinner fast and the fridge is looking bare. Red lentils, a can of coconut milk and a few pantry spices turn into something so cozy and flavorful that it has become one of my most-made weeknight meals. A squeeze of lemon at the end makes all the difference.

It's a must-make.

Here is why you will love this red lentil soup:

  • Ready in 30 minutes. A quick, one-pot weeknight dinner.
  • So much flavor. Curry powder, garlic, ginger, coconut milk and fresh lemon.
  • Healthy and filling. Packed with plant-based protein and fiber.
  • Make-ahead friendly. It keeps well in the fridge and freezes great.

Creamy, cozy and ready in 30 minutes.

Let’s talk texture and flavor.

Red lentils break down as they cook, giving the soup a naturally thick, creamy body without any cream. Coconut milk adds richness, curry and ginger bring warmth, and lemon juice brightens everything right at the end. Leave it chunky or blend it smooth.

What you'll need.

Here is what you need to make red lentil soup:

  • Coconut oil – or olive or avocado oil.
  • Onion, celery and carrots – the flavor base. Pre-diced mirepoix saves time.
  • Garlic and ginger – fresh or from a jar.
  • Curry powder – mild or hot, your choice.
  • Red lentils – they cook quickly and break down into a creamy soup.
  • Vegetable broth – regular or low-sodium.
  • Canned coconut milk – unsweetened, full-fat or light.
  • Lemon juice – one medium lemon gives about 3 tablespoons.
  • Salt and pepper – to taste.
  • Fresh cilantro – optional, for garnish.

For exact ingredient quantities, please see the recipe card below!

Customize it your way.

Make this red lentil soup your own:

  • Lentils – use green, brown or a blend (they take longer to cook).
  • Spices – add cumin, coriander, cinnamon or smoked paprika.
  • Heat – use hot curry powder or add red pepper flakes or a chopped Thai chili.
  • Veggies – stir in diced sweet potato, tomato or a handful of spinach.
  • Texture – blend with an immersion blender for a smooth soup.

Flexible dietary swaps.

This soup is naturally vegan, gluten-free and dairy-free. A few more ideas:

  • Lower fat – use light coconut milk.
  • Oil-free – sauté the vegetables in a splash of broth.
  • Lower sodium – use low-sodium vegetable broth.

How to make red lentil soup.

It all happens in one pot:

Sauté the vegetables

Cook the onion, celery and carrots in coconut oil until very tender.

Add the aromatics

Stir in the garlic, ginger and curry powder and cook for 2 minutes.

Simmer the lentils

Add the lentils, broth, salt and pepper and simmer until the lentils are tender.

Finish and serve

Stir in the coconut milk and lemon juice, season and garnish.

How to serve it.

Serve it hot with your favorite toppings:

  • Garnish with fresh cilantro, parsley or chives.
  • Top with a swirl of coconut milk or a dollop of plain yogurt.
  • Serve over rice or with naan or crusty bread.
  • Make it flex – stir in shredded rotisserie chicken or top each bowl with grilled shrimp.

Kori's tips.

  • Rinse the lentils before cooking.
  • Use canned coconut milk, not the carton kind.
  • The soup thickens as it sits, so thin it with a little broth when reheating.
  • Add the lemon juice at the end for the brightest flavor.

FAQs

How do you store red lentil soup?

Once cooled, store it in an airtight container in the fridge for up to 5 days.

Can you freeze red lentil soup?

Yes. Freeze it in airtight containers for up to 3 months, then thaw overnight in the fridge and reheat on the stove.

Do I need to soak red lentils?

No. Red lentils cook quickly without soaking. Just give them a rinse.

Can I use other lentils?

Yes, but green and brown lentils hold their shape and take longer to cook, so add more simmering time.

Is red lentil soup healthy?

Yes. It is packed with plant-based protein and fiber, and it is naturally vegan, gluten-free and dairy-free.

Kori's Tips

For more helpful hints, substitution ideas, cooking tips, and other delicious recipes check out my post above.
TIPS: Use canned unsweetened coconut milk, not the carton kind. To save time, use a 10 to 12-ounce package of pre-diced mirepoix (onion, celery and carrot) from the produce section. The soup thickens as it sits, so thin leftovers with a splash of broth.
VARIATIONS: Use any lentils you like (cook time will be longer for green or brown). Add cumin, coriander or smoked paprika, use hot curry powder for heat, or stir in diced sweet potato or tomato. Blend with an immersion blender for a smooth soup.
MAKE IT FLEX: Stir in shredded rotisserie chicken or top each bowl with grilled shrimp.
SERVING SUGGESTIONS: Garnish with cilantro, parsley or chives. Top with a swirl of coconut milk or a dollop of plain yogurt, and serve with naan, crusty bread or over rice.
