Red lentils are one of the easiest ways to make a soup feel comforting fast. Pair them with Thai curry paste and coconut milk and you get something that tastes brighter and more layered than standard lentil soup.

Why This Recipe Works

Red lentils break down naturally as they simmer, which thickens the soup without any blending or extra starch.

Ingredients

  • 1 tbsp neutral oil
  • 1 onion, diced
  • 1 tbsp grated ginger
  • 3 tbsp red curry paste
  • 1 cup red lentils
  • 1 can coconut milk
  • 4 cups vegetable stock
  • 2 cups baby spinach
  • Lime wedges for serving

Instructions

  1. 1

    Cook the onion and ginger in the oil until softened, then stir in the curry paste.

  2. 2

    Add the lentils, coconut milk, and stock and bring to a simmer.

  3. 3

    Cook for about 20 minutes until the lentils are very soft.

  4. 4

    Stir in the spinach until wilted.

  5. 5

    Finish with lime juice and serve hot.

Serving Suggestions

Ways to Serve This Dish

  • Pair with a side of pickled vegetables or kimchi

  • Add a drizzle of sesame oil and toasted sesame seeds for extra flavor

Substitutions

Curry Paste

Helpful Pantry Staple

Why the curry paste matters

This is where the aromatic base starts. A well-made curry paste gives you more complexity up front and saves a lot of rebuilding later.

The flavor base starts here, not with the garnish.

  • Delivers the backbone of the sauce
  • Useful across soups, curries, and noodle dishes

A better curry paste is usually more noticeable than buying another pan.

Tips & Storage

Pro Tips

  • Add more stock if you want a looser soup after the lentils finish swelling.

  • A spoonful of chili crisp on top is excellent if you like more heat.

Storage

Refrigerate for up to 5 days.

Reheating

Reheat gently on the stovetop, thinning with water or stock as needed.

Frequently Asked Questions

Can I use green lentils?
Red lentils work best here because they soften quickly and make the broth creamy.
Is it very spicy?
It depends on your curry paste, so start with less if you are unsure.
