Instructions

Heat the olive oil in a large pot over medium heat. Add the chopped onion and sauté for 3–4 minutes until translucent, then stir in the garlic and cook for another minute.

Add the diced carrots, celery, and potatoes to the pot and cook, stirring occasionally, for about 5 minutes until the vegetables begin to soften slightly.

Stir in the tomato paste, ground cumin, and sweet paprika, and cook for 1–2 minutes to toast the spices and develop the flavor.

Rinse the red lentils thoroughly under cold water, then add them to the pot along with the broth and the bay leaf. Stir everything together well.

Bring the soup to a boil, then reduce the heat, cover partially, and let it simmer for 20–25 minutes, stirring occasionally, until the lentils and vegetables are completely tender.

If using sausage, add the sliced sausage to the soup during the last 8–10 minutes of cooking so it heats through and flavors the broth.

Remove the bay leaf. For a creamier consistency, use an immersion blender to partially blend the soup, leaving some texture. Stir in the apple cider vinegar and season with salt and pepper to taste.

Ladle the soup into bowls and serve hot, optionally garnished with fresh parsley and crusty bread on the side.

History & Origin

Lentil soup is one of the oldest dishes known to humankind — lentils have been cultivated and eaten since antiquity across the Middle East and Mediterranean. In Germany, a hearty version with root vegetables and spices has become a staple of home cooking, with slight regional variations throughout the country. The use of cumin and turmeric reflects how deeply Middle Eastern and Oriental influences have shaped everyday German cuisine.

Variations

The vegan version is already built right into this recipe — for something even more filling, swap out some of the carrots for diced sweet potato.

With meat: If you’re not vegetarian, render 150g of diced chorizo or bacon in the olive oil at the very beginning — it adds a wonderful smoky depth to the soup.

Middle Eastern twist: Replace some of the broth with 200ml of coconut milk and stir in a teaspoon of harissa for a creamy, mildly spicy lentil cream soup.

Use green or Puy lentils instead of red — they won’t break down, giving the soup more texture and a rustic bite; just plan for a longer cook time of about 40–45 minutes.

Common Mistakes – and How to Avoid Them

Skipping the rinse: Unrinsed red lentils can make the soup cloudy and slightly bitter — always give them a quick rinse under cold water.

Salting too early: Adding salt at the start of cooking can cause lentils to take longer to soften — wait until toward the end to season.

Simmering at too high a heat: At a rolling boil, lentils can easily scorch on the bottom of the pot — keep the heat low to medium, cover with a lid, and stir occasionally.

Leaving out the lemon juice or adding it too early: Acid added before the end of cooking can keep lentils firm — always stir in the lemon juice right at the end when adjusting seasoning.

Not using enough liquid: Red lentils swell considerably and soak up a lot of broth — err on the side of adding more liquid upfront and let it reduce, rather than constantly having to add more.

Storage & Shelf Life

The soup keeps well in a sealed container in the refrigerator for 3–4 days. It also freezes beautifully — stored in individual portions, it will last up to 3 months. When reheating, the soup will have thickened; simply add a splash of water or broth and warm it over medium heat, stirring occasionally. Avoid repeated boiling.

What to Serve With It

This soup pairs wonderfully with a hearty farmhouse bread or toasted sourdough for dipping. A dollop of plain yogurt or crème fraîche on top rounds out the flavors and adds a pleasant freshness. To drink, try a sparkling mineral water with lemon or a light white wine such as Grüner Veltliner. This soup works great as a warming weekday lunch, an easy Sunday dinner for the whole family, or a budget-friendly, nutritious option for weekly meal prep.

Frequently Asked Questions

Can I use lentils other than red lentils?

Yes, green or brown lentils work fine too, but they’ll need an extra 10–15 minutes of cooking time and will hold their shape more. Yellow lentils are a great substitute for red lentils.

Why isn’t my lentil soup turning creamy?

Red lentils naturally break down as they cook and become creamy on their own. The key is to simmer them long enough (20–25 minutes) and then partially blend the soup. Too little liquid can also be a factor.

How do I make this lentil soup vegan?

The base recipe is already vegan as long as you use vegetable broth. Simply skip any sausage or bacon additions and season a little more generously with spices and fresh herbs.
