Lemon Lentil Soup

Lemon and herbs bring magic to a simple pot of soup!

I wanted to do a riff on our red lentil stew from last week but without using tomatoes this time. A different flavor profile makes eating lentils on the daily actually exciting.

Instead of using plain vegetable stock here I opted for filtered water that I infused with just a tiny pinch of saffron threads I had in the pantry. A sweet, flowery aroma and beautiful color is what you get by just letting those two hang together while you get the base of this lemony soup going with the aromatics: onion, carrots, cumin and turmeric.

Lemon Lentil Soup Ingredient Notes

  • Aromatics – the usual suspects: onion, carrot and garlic sauteed together until softened and their sugars have concentrated to create the first layer of flavor.
  • Herbs – variegated lemon thyme is a favorite herb I grow in containers year round as it pairs wonderfully with so many dishes, especially this soup. You can do your own spin on this recipe and substitute the thyme with rosemary, parsley and even mint.
  • Red Lentils – the best lentil for a creamy quick soup. They break down fast and naturally thicken the broth. You could use brown or French lentils if you wanted to but those take way longer to cook and the color won’t be as pretty. Basically you’d be making another soup.
  • Spices – earthy cumin, a touch of turmeric, some spicy chili flakes, lemon peel and sweet floral saffron create a uniquely lovely flavor profile.
  • Lemon – the fresh kind to brighten up the final soup and control how lemony you really like it. Save it for last and serve extra lemon wedges on the side.
  • The Broth – you really could use a low sodium veggie broth if desired, however mixing some hot water with a pinch of saffron like I did will give you an instantly amazing broth with a unique aroma that really compliments this soup.
  • Add Ins – bump up the nutrition profile with micro-greens or chop up some Swiss chard leaves, kale or spinach to stir into the soup at the last minute just until wilted.

FAQ

How Long Does Homemade Lentil Soup Last?

Most homemade soups keep well for one week in the refrigerator in a lidded airtight container or jar. Leftovers can also be frozen and stored for up to six months in freezer proof mason jars or containers. Make sure to thaw them out in the refrigerator before reheating.

Do You Have to Soak Lentils Before Cooking Them?

Unlike beans, lentils have thin skins and do not need to be soaked before cooking. Specifically red lentils have a very quick cooking time of about 15 minutes which makes them ideal for quick, last minute meals. Make sure to pick through them and give them a good rinse.

How To Make Lemon Lentil Soup Creamy?

I pureed only about half of the soup for a creamy rustic texture. If you are looking for an extra silky and creamy finish add a splash of coconut milk and puree the entire batch preferably in a very powerful blender until obliterated. If you find that your soup leftovers have thickened a little too much just add a little splash of water or veggie stock to thin it out when reheating.

Reheating

You can reheat the soup on the stove top in a small sauce pan, or microwave for 2.5 to 3 minutes so long as you don’t use plastic.
