Substitutions

Lentils

I usually prepare this lentil soup with green or brown lentils. These keep their shape and at the same time thicken the soup.

You could also use black lentils, but this soup won't be as creamy as with green lentils.

I can't really recommend red lentils or yellow lentils, as they disintegrate very quickly and you end up with a mushy soup. If you want to use red lentils, I can recommend making red lentil dal.

Miso Paste

If you don't have miso paste at home or don't want to use it, I can recommend using soy sauce, tamarind or coconut aminos to create a delicious umami taste.

You can also add a teaspoon or more of my delicious stock powder to give it extra flavor.

Nutritional Yeast

Nutritional Yeast flakes are optional but I think they give that certain something and give the lentil soup a great taste.

Variations

For this soup, too, I would like to briefly discuss various forms of diets.

Gluten free

This vegan lentil soup is gluten free. If you choose to not use miso, but want to use soy sauce, make sure that you use a gluten-free soy sauce (tamarind) or coconut aminos.

Keto and Paleo

Legumes are not allowed in either diet, keto or paleo. Since this is a lentil soup, I cannot give you a recommendation for a substitution here.

Low Carb

If you want to eat low carb lentil soup, you can replace the potatoes with cauliflower florets.

Instructions

Dice the onion and the garlic clove. Fry them in a pressure cooker (instant pot) without the lid. Always add a sip of water so that they do not stick to the pot.

Cut the potatoes and carrot into bite-sized pieces and place them with the lentils and the water or vegetable broth in the pressure cooker.

Cook the lentils under high pressure for about 15-20 minutes. Let the pressure cooker cool down and let the pressure release naturally. Takes about 10 minutes. After the 10 minutes let the remaining pressure out.

You may have to add some more water or vegetable broth. Depending on how thick you like the soup.

Are the lentils soft enough for you?

Add chopped parsley, smoked paprika, apple cider vinegar, miso paste, white pepper, nutritional yeast and give it a good stir.

Bring to boil again and season with sea salt and pepper to your own taste buds.

Which Instant Pot Size?

Put this lentil soup in a 4-6 liter pressure cooker. You can also put it in an 8 liter pot.

Make sure that the pot is not too small, otherwise the soup may not be able to boil properly under pressure. Make sure you're not over the max line.

Prepare in Advance

This vegan lentil soup is easy to prepare in advance and is therefore a great meal prep. You can also prepare the soup in larger quantities, simply double the amount.

Serving Options

A delicious baguette, for example my whole wheat baguette, goes wonderfully with this soup. Or serve it with delicious rolls.

You can also serve rice with it, I don't think the soup needs a side dish and is great as a stew without anything to eat.

Storage

Have you cooked too much lentil soup and still have leftovers? No problem. I'll show you how to store them here.

How to Refrigerate It?

The vegan lentil soup can be kept in an airtight container in the refrigerator for about 5 days.

Simply warm the soup in a saucepan over medium heat until it is warm.

How to freeze it?

Freeze the lentil soup in portions. The soup will last there for about 2-3 months. To serve, remove from the freezer the night before and let thaw in the refrigerator. To warm up, perform the steps as described above over medium heat.

Tips

You can also add a little more apple cider vinegar. I usually add a sip at the end because we like the vinegar flavor in lentil soups. Here you can adapt it to your own taste.

If you don't have fresh parsley, just add 2 teaspoons of dried parsley.

If you want to season your lentil soup, make sure that you only add salty products such as miso paste after cooking. Salt can prevent the lentils from becoming soft.

Add chopped tomatoes, leafy vegetables and various herbs to the lentil soup so that it doesn't get boring.

Slow Cooker

Lentil soup should be great to prepare in a slow cooker. Simply let the lentils simmer in the slow cooker.

Proceed as above and fry the onions first and then add all the other ingredients and let it simmer on a low for the day.

Normal Pot

You can of course cook the lentil soup in a normal saucepan, but the cooking time will be longer. Check the consistency of the lentils every now and then and when they are soft, your soup is ready.
