Key Ingredients
This lentil barley soup recipe is a filling meal that will keep you satisfied. It layers lots of flavor in easy steps using simple ingredients you’ll easily find at the grocery store. Some may even be pantry staples for you. The pearl barley and lentils build a hearty foundation while the veg add texture and flavour. If those I’ve used aren’t in season for you replace them with what you have on hand.
- Pearled barley – gives the soup plenty of body and the starch it contains slightly thickens the broth.
- Dried green lentils – also contribute to the soup’s texture by acting as a natural thickener. They help create a creamy, velvety consistency and add depth to the overall taste of the soup.
- Chicken stock – provides the savoury backbone and umami taste that ties the grains and vegetables together. This can be replaced with vegetable stock or broth if preferred.
- Leek – mild, sweet, and complex onion-like flavour that forms a soft aromatic base.
- Kale – contributes earthy, slightly bitter flavours that balance the richness of the stock.
- Carrot – brings natural sweetness that rounds out the soup.
- Potato – adds starch, that thickens the soup and makes it creamy when blended.
- Mushrooms – contribute a deep, earthy flavour and a rich, savory umami taste.
- Dried thyme and oregano – this combination adds warmth, earthiness, pungency and a slight bittersweet taste to the soup.
- Fennel seeds – provide a subtle anise note that lifts the savoury flavours.
- Fresh Garlic – contributes plenty of pungency.
- Olive oil – used to gently sauté the veg and aromatics in addition to adding its own unique taste.
- Salt and pepper – enhance and balance all the other ingredients.
- Flat-leafed/Italian parsley – adds colour and a distinctly herbaceous flavor to the finished soup.
- Grated parmesan cheese – optional, but contributes more creaminess.
To make this extra decadent add a dollop of sour cream or Greek Yogurt into the hot soup bowls just as they’re being served. Then sprinkle with the chopped parsley or any fresh herbs of your choosing.
Substitutions And Variations
To make this a vegan soup replace the chicken stock with vegetable broth or stock.
For a Middle Eastern inspired flavour profile, swap out the thyme, oregano and fennel for 1 tsp cumin, 1 tsp allspice, and ¼ tsp cinnamon. Also increase the barley and lentils to 1 and ¼ cups each and make it more stew-like.
Add a squeeze of lemon juice or lime juice to the soup once ready to balance the richness and saltiness, and to add a fresh, zesty taste.
Swiss chard can replace the kale if preferred or if kale isn’t in season.
Want a smoother soup? Simply add all of it to a blender and blend until you reach your desired consistency.
For a gluten free version replace the barley with brown rice. To do this though I recommend cooking the rice in separate pot so it doesn’t over-cook and become soggy. Also – if you have leftovers do not store the rice in the soup, as this is another thing that will make it soggy. See recipe card for more details.
How To Make This Barley And Lentil Soup
This is the perfect soup for a cold winter day or for cool weather during the changing seasons. Be sure to use a very large pot to make this in. You’ll need one that can hold at least 4 quarts/litres.
- Heat the olive oil in a large pot over a medium heat. Add in the sliced leek and sauté for 4-5 minutes, stirring frequently until soft.
- Add in the remaining tablespoon of olive oil and stir in the spices. Cook for 30 seconds until fragrant, then add the garlic, sliced mushrooms, kale, carrot, potato, half a teaspoon of salt and plenty of fresh ground pepper.
- Next, pour in the sliced mushrooms, kale, carrot, potato, half a teaspoon of salt and plenty of fresh ground pepper. Sauté for 4-5 minutes or until the veg start to soften.
- Add the rinsed lentils and barley to the pot, along with the other half a teaspoon of salt, more fresh black pepper and the stock. Give everything a good stir.
- Bring to the boil, then reduce the heat to low and let the soup simmer for 30 minutes or until the barley and lentils are tender.
- Using a stick blender, roughly blend the soup to thicken it slightly, and add in the parsley and grated parmesan if using.
- Serve drizzled with olive oil, a little more parmesan and crusty bread for a hearty meal.
The barley still has some bite when simmered for 30 minutes. If your preference is to have it softer, cook the soup for an extra 15-20 minutes.
Tips For Success With This Recipe
Don’t skip on rinsing the barley and lentils before you start. This helps remove dust and excess starch, which can give the soup a gritty mouthfeel.
Keep an eye on your soup and ensure its simmering, not boiling. You don’t want to lose too much liquid to evaporation.
While the stock can be replaced with water I don’t recommend it. Using stock gives the soup a rich, satisfying flavour.
Storing And Freezing
Cool the soup completely before storing leftovers in an airtight container in the fridge for up to 5 days or freezer for up to 6 months. If freezing, leave some space at the top of the container for expansion.
Just note that the barley will continue to absorb liquid and can become soft. If it becomes too thick for your liking, add ¼ – ½ cup more stock to reach your desired consistency when re-heating. Add fresh lemon juice and a sprinkle of salt to revive flavours.
Barley And Lentil Soup FAQs
No, the barley and lentils cook along with the veg so it’s a quick and easy one pot recipe.
Yes, barley does contain gluten. For a gluten free version of this recipe check the tips for success section or the recipe card.
You can, though its not necessary. Soaking grains and legumes like the barley and lentils is often done to aid digestion and may be helpful for people with digestive concerns. If doing so the cooking time and amount of liquid added should be reduced.
