Making the soup: step by step

The method is simple. Sauté aromatics, add potatoes and lentils, simmer until soft, then blend to your preferred texture.

Step-by-step instructions

1. Heat olive oil in a large pot over medium heat. Add onion, carrot, and celery. Cook 5–7 minutes until soft.
2. Stir in garlic, cumin, paprika, and thyme. Cook 30 seconds until fragrant.
3. Add diced potatoes, rinsed lentils, vegetable stock, and water. Bring to a simmer.
4. Reduce heat, cover, and cook 20–25 minutes, until lentils and potatoes are very tender.
5. Use an immersion blender for a mostly smooth soup, or cool slightly and blend in batches in a blender. Leave some texture if you like.
6. Return to the pot and warm gently. Stir in lemon juice and adjust salt and pepper.
7. Serve with a swirl of yogurt or coconut cream and a sprinkle of fresh parsley.

Tips for texture, timing and tools

• An immersion blender gives the fastest finish and keeps cleanup low. For chunkier soup, pulse briefly.
• Red lentils break down faster than brown or green lentils. If you use those, increase cooking time.
• If the soup gets too thick after blending, thin with warm stock or water one ladle at a time.
• Taste for salt after blending; flavors mellow when pureed. For a brighter finish, add lemon juice last.
• If you want to add a smoky note, finish with a light drizzle of smoked paprika oil or a pinch of smoked salt.

Keeping and reheating leftovers

This soup stores very well and makes an excellent make-ahead meal.

How to store it right

Cool the soup to room temperature, then transfer to airtight containers. Keep in the refrigerator for up to 4 days. For longer storage, freeze in single-serving portions for up to 3 months.

Reheating without losing flavor

Reheat gently on the stove over low heat. Thin with a splash of water or stock as it warms. If using a microwave, stir every minute to heat evenly. Add a fresh squeeze of lemon right before serving to brighten the flavors.

A dish worth making again and again

This recipe scales easily. Double the batch for freezer meals or smaller portions for quick lunches. Garnishes like herbs, yogurt, or crunchy seeds make each bowl feel new.

FAQs

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

Yes, but brown and green lentils keep their shape more than red lentils. They need longer cooking, so simmer until tender and expect a chunkier texture. Increase simmer time by 10–15 minutes.

Is this soup gluten-free and vegan?

Use gluten-free stock and a plant-based finish (coconut cream or plant yogurt) to make the recipe both gluten-free and vegan. The core ingredients potatoes and lentils are naturally gluten-free.

Can I make this in a slow cooker or Instant Pot?

Yes. For a slow cooker, cook on low 4–6 hours. For an Instant Pot, use the soup or manual setting for 8–10 minutes and quick-release. Blend after cooking for a smooth texture.

How can I add more protein?

Lentils already add good plant protein. For extra protein, stir in cooked quinoa or top each serving with toasted pumpkin seeds or a spoonful of plain Greek yogurt if you include dairy.
