Why This Recipe Works

This vegan linzen (lentil) soup is delicious, sure, but it’s also a nutritional powerhouse! It works so amazingly for a number of reasons.

It’s So Flavourful

As you dry-fry the onions, you’ll coax their natural sweetness into this dish. This caramelises the flavours—and sets the base for the magic to come. As you later add smoked paprika, you’ll get that delicious taste of smokiness.

So Many Textures

The lentils slightly disintegrate as you slow-cook them. This creates a creamy base for our recipe. Simultaneously, the diced vegetables (especially the potatoes with their skins on) add a delightful contrast in texture.

Marvelling Micro- and Macro-Nutrients

This whole food plant-based recipe is incredibly healthy for the whole family. Lentils are the star of the show—and provide a whopping 10.5 grams of protein per serving. This (plant-based) protein keeps you feeling full for long periods.

So, if you’re looking to manage your weight, this soup is a great idea! Plus, with over 10 grams of fibre per serving, this soup promotes gut health.

Low in Calories

As you dry-fry the ingredients, you ensure your recipe is oil-free. This means less calories and no unhealthy fats. So, if you’re watching your weight, this protein and fibre-packed soup will be your best friend (and your taste buds will love it, too!).

Recipe Ingredient Notes

Let’s dive into the ingredients you’ll need for this vegan linzen (lentil) soup. They’re pantry staples, but if you don’t have them, you can readily source them from your nearest grocery store, or opt for alternatives.

Onions. These are going to create the savoury base for our recipe. In terms of benefits, onions are anti-bacterial and support bone and heart health.

Garlic cloves. These add a pungent taste that mellows as the recipe will simmer. Plus, garlic can help boost your immune system—and fight the cold and flu. (If one of your loved ones has a cold, you know what to whip up for them!).

Smoked paprika. This will add a depth of flavour to the recipe. You can replace this with sweet paprika or Hungarian paprika (but for a slightly different flavour profile).

Parsnips. These add earthiness as well as sweetness to the soup. Parsnips provide your body with antioxidants and may help with your weight loss goals.

Potatoes. When you cook these until they become tender, you’ll be adding body to the soup. I recommend leaving on the skins; this adds texture (as well as fibre and micro-nutrients). If you’re looking for some natural sweetness, sweet potatoes can make a good substitute. 

Carrots. This ingredient will factor in that stunning orange colour into the recipe. Plus, carrots provide a crazy amount of beta-carotene—your body will later use this to make vitamin A.

Green lentils. The heart of the soup! These add protein and fibre to our vegan linzen soup. The cool part is that green lentils cook quickly and wouldn’t require pre-soaking. You may use brown or black lentils instead, but these have different cooking times.

Celery. This is going to add a subtle salty vegetal flavour to the soup. Oh, and that crunch! If celery isn’t available, you can easily use celeriac or leeks, for example.

Vegetable stock + 1 tbsp Marmite (or any yeast extract). These ingredients add flavour to the soup. You can use homemade vegetable broth for a stronger flavour—or store-bought options for added convenience. Marmite, on the other hand, adds a satisfying umami taste.

Dry mixed herbs. A blend of dried herbs (e.g. thyme, oregano, and rosemary) adds complexity to the soup. I also love the added earthiness!

Parsley. Fresh is preferable, but you can also use dried parsley.

Essige Essenz Vinegar (or Red Wine Vinegar). Vinegar adds a splash of acidity to our recipe. You can use any vinegar you have available, though.

Pinch of salt & pepper to taste.

How To Make Vegan Linzen (Lentil) Soup

Got all those ingredients prepped? You need a further 40 minutes to have the soup ready to devour—using the following steps.

Fry the onions for a few minutes, generally until they’re slightly browned. Remember, we don’t need any oil as we can deglaze onions with vegetable stock or water! 

Then, add the garlic and the smoked paprika. Fry for a few more minutes—and when you need to deglaze along the way, don’t hesitate to add more veg stock (1 tablespoon at a time).

After a few minutes of frying, add the lentils, vegetables, the rest of the vegetable stock, herbs and vinegar of choice.

Bring to a boil, then reduce the heat to low-medium and simmer on the hob with a lid on for at least 35 minutes.

This recipe also works well in a slow cooker. My slow cooker was on a medium-high for 6 hours; you want to set yours appropriately.

When ready to serve, add more fresh parsley, vinegar, salt, and pepper to taste. 

And enjoy! 😋 💚 You can devour the soup on its own or with a side of Mexican salad. You can also have it with mushroom fried rice—either individually or by adding the rice to your soup bowl for mingled flavours.

Variations, Ideas & Notes

There’s so many ways you can adapt the soup recipe to your taste preference. I’ve got some ideas for inspiration—but you can play around with them as you wish.

  • Swap up the flavours. Love some spice? Adding red pepper flakes as you fry the onions will do the trick. If you like a smokier flavour, you can add liquid smoke towards the end of cooking.

  • Play with textures. For a creamier soup: after you’re done blending a portion of the cooked lentils with some vegetable stock, return it to the slow cooker and stir to combine. You can also add some crunchy toppings. Think finely chopped nuts or toasted bread crumbs. 

  • Boost the veggies. You can make this soup as healthy as you wish! Add some green beans, frozen peas, courgette (zucchini), black-eyed peas (cowpeas) etc.

Pro Tips For The Vegan Linzen (Lentil) Soup Recipe

Before I wind up the recipe, I’ve got some pro tips that I want to share with you—

  • The real key to this soup is the vinegar. I prefer Essig Essenz (a strong , spicy German vinegar) for this recipe but use what you have and the quantity that suits you best.

  • While this recipe works great in a slow cooker, it can also be cooked on the hob: First, fry the onions with garlic and paprika. Again, no oil is needed, just use vegetable stock to deglaze. Add all the ingredients, bring to a boil, and let simmer on low/medium heat for at least 35 minutes. Keep the lid on, and add more stock/water as needed.

  • As with all soups and stews, this recipe offers an excellent opportunity to use up whatever vegetables you have at the time 😊

Frequently Asked Questions

What to do with leftover vegan linzen (lentil) soup?

If you’ve got leftovers, toss them into the refrigerator. They’ll do well in an airtight container for up to 4 days.

When reheating, you can add some vegetable stock if you want to thin the consistency. And if you’re looking to meal prep in advance, you can also freeze the soup for 3 months. Just be sure to thaw it overnight (in the fridge) before you reheat it.

Can I use red lentils instead of green lentils?

Yes, but red lentils break down more, making the soup creamier. Green lentils hold their shape better.

How can I make this soup even more protein-rich?

You can add chickpeas, tofu, or nutritional yeast for an extra protein boost.

What can I serve with this soup?

It pairs well with whole-grain bread, a fresh salad, or even brown rice for a heartier meal.

How do I make it spicier?

Add red pepper flakes, cayenne pepper, or a dash of hot sauce to taste.
