Here's alentil soup recipe, aka Linsensuppe,you can put together quickly in the morning and come home to a delicious dinner. (This Oma just lovesslow cooker soups!)

You can make it avegansoupor add some meat such as smoked sausage. Either way -- delicious! I like adding tomatoes, a great variation on the traditional lentil soup. If you want really traditional, omit the tomatoes.

Make this with or without meat. Smoked sausage is wonderful. A slab of smoked bacon with rind is fabulous. Check out the "a bit of this and a bit of that" at the end of the recipe for so many different ways to create your ownslow cooker lentil soup recipe.

A bit of this and a bit of that ...

  • If you don't have vegetable stock, use water and vegetable bouillon cubes using the quantities on the bouillon package to make up 8 cups of stock.
  • Want some other flavors? The following are nice in this: cumin, coriander, turmeric, thyme, or oregano. Finish off with a bit of lemon juice or vinegar (that's German). Add 1/2 cup chopped fresh cilantro just before serving.
  • Add a bunch of chopped fresh spinach about 1/2 hour before soup is done for an extra punch of vitamins.
  • Traditionally, tomatoes and cauliflower are not part of this soup. Potatoes are.
  • Not vegetarian or vegan? Use chicken stock for a really rich flavor. Also Feta sprinkled on each serving is a treat. Add some smoked sausage or wieners for some hearty flavor!

My Way ...

  • I usually make this with some kind of meat broth ... adding smoked sausages.
  • However, if you're into some meatless meals, this one is an easy one to start with.
  • It's so healthy ... with protein from the lentils ... that you really won't miss the meat.
  • This is great with any number of veggies added.
  • Change the spices. Make it your own! Change the way you serve it ... with vinegar or honey!
  • I love using my Cuisinart multi-cooker slow cooker for this. However, you can cook it on the stove top as well. Plan for about 1 to 2 hours cooking time on a gentle simmer.

How to serve Lentil Soup ...

I grew up with adding a spoonful of vinegar to my bowl of soup. So good!

However, my Vati's Mutti would add a spoonful of honey to her bowl. Somehow I never could try it her way. I just loved my 'vinegary' taste too much :)

Are there any other things you add to your lentil soup? Let me know!

Looking for other bean soup recipes?

How about a red lentil soup? I've got a one that's so quick to make.

Red lentils will cook in about 1/2 hour and taste much more delicate than the green or brown.

Why does my lentil soup taste bland? ›

Not adding any aromatics to the pot.

Add aromatics to the water or, even better, use chicken or vegetable stock instead of water. Follow this tip: Add a few cloves of garlic, a bay leaf, a spring of rosemary, half of an onion, or a combination of these aromatics to the cooking water or stock to help flavor the lentils.

Why is my lentil soup not thick? ›

Cook It Longer

Sometimes soup just needs to simmer longer to reach the perfect consistency. Check to see if the vegetables are tender, and then taste the broth. If the soup tastes a bit watery, give it more time.

Do lentils thicken a broth? ›

You'll find that the lentils mostly breakdown and naturally thicken the soup. But what I like to do to get a really luscious creamy texture is to give the soup a quick whizz with a blender stick (or transfer a couple of cups to the blender) to puree SOME but not all the lentils.

Is lentil soup meant to be thick? ›

It's all whipped up in one pot with simple and inexpensive ingredients like fresh veggies, bold spices, and of course plenty of lentils. It's a wonderfully thick soup that's equal parts filling and flavorful!

How do you fix bland lentil soup? ›

To avoid a bland lentil soup, use a flavorful broth—whether that's homemade or store-bought chicken or vegetable broth. The other key is building flavor. To do so, use aromatics like onions and garlic, include fresh or dried herbs, and season well with salt and pepper.

What can you add to lentils to make them taste better? ›

You can also add salt, aromatics like a halved onion, herbs, and spices to the pot before the lentils and the water, like beans, or wait until they're done cooking to flavor them.

Can you overcook lentils in soup? ›

This time, it turned out mushy and there wasn't a whole lentil to be found. Damn it! I figured out later that it spent about 2.5 hours too long in the slow cooker (a little miscalculation on my part). If you're like me and have overcooked Lentil Soup then you're in luck because I'm going to show you how to revive it.

What can I use to thicken lentil soup? ›

Add flour or cornflour

Put a tablespoon of either into a small bowl and stir in 2-3 tbsp of the soup until you have a smooth mixture. Stir this back into the soup and bring it to a simmer. Cook for a few minutes to allow the starch granules to burst to thicken, and to cook out any flour flavour.

How do you thicken soup in a slow cooker? ›

Add a slurry at the end.

A slurry is a mixture of flour and water, whisked together until smooth and added towards the end of cooking; it's a super-simple way to thicken any soup. For slow cooker soups, add your slurry with at least 30 minutes of cook time left so that the raw flour can cook and thicken the soup.

Do I need to rinse lentils for soup? ›

Lentils do not require it but can be soaked in order to reduce cooking time by about half. Before cooking, rinse lentils in cold water, pick over to remove debris or shrivelled lentils, then drain.

How much liquid do I need for a cup of lentils? ›

Cook on a stovetop, using 3 cups of liquid (water, stock, etc) to 1 cup of dry lentils. Be sure to use a large enough saucepan as the lentils will double or triple in size. Bring to a boil, cover tightly, reduce heat and simmer until they are tender.

What color lentils are best for soup? ›

I recommend using green or French green lentils because they hold their shape in the soup, adding satisfying texture. Brown lentils are also a fine option.

What is the white foam on lentil soup? ›

That means the foam will typically appear when making meat-based broths and, to a lesser degree, soups made from high-protein vegetables such as chickpeas and lentils. When those coagulated proteins cluster together, they can create air pockets, which is what causes the “sudsy bubbles,” says Trout.

What is the white stuff in lentil soup? ›

Those look to be radicles (embryonic stems, the part the root grows from) that have separated from the lentils. If you look closely at the less squished lentils in your soup, you'll probably see some with the radicles still attached.

How do you fix flavorless soup? ›

If a soup is tasting bland in the bowl, consider adding acid rather than salt. A squeeze of lemon or lime, or a dash of yogurt or sour cream can add brightness to the bowl. Our Lemony Chicken Soup will make your mouth water.

Why are lentils so bland? ›

First things first, ditch boiling your lentils in plain water. Plain water is boring and makes for boring lentils. Instead, upgrade your cooking experience by boiling the lentils in your stock of choice. We suggest trying our vegetable stock recipe.

How can I deepen my soup flavor? ›

Vinegar – A spoonful of vinegar is a quick fix when you find yourself with a bowl of dull, flat-tasting soup. Just a small amount of acid will brighten up the flavors. 2. Soy Sauce – Soy sauce is another item that's ideal for brightening up and adding depth of flavor to an otherwise dull soup.

How do you salvage bland soup? ›

Not enough depth: A well-rounded soup has multiple layers of flavour, including acidity, umami, and sweetness. If your soup is missing any of these, it may taste bland. Adding ingredients like vinegar or lemon juice for acidity, parmesan cheese for umami, or even a touch of sweetness can make a world of difference.
