Barley Soup with Greens, Fennel, Lemon, and Dill

This vibrant barley soup with greens is a deeply nourishing vegetarian dish that celebrates the earthy flavours of pearl barley and fresh garden herbs. The base is built with slow-cooked onions and a light vegetable stock, providing a savoury depth that perfectly complements the iron-rich kale, chard and spinach. With the aromatic addition of fennel fronds, dill and mint, this soup offers a refreshing brightness that lifts the hearty grains, making it a wonderful choice for a restorative lunch or a light midweek dinner.

Packed with fibre and essential vitamins, this homemade soup is as healthy as it is comforting. The salty crumble of feta cheese and a final zest of lemon juice create a beautiful balance of flavours. For the best results, serve it in wide bowls with a crusty piece of sourdough bread to soak up the herb-infused broth. It is an excellent recipe for meal prep, as the flavours develop and improve the following day.

How to make Barley Soup with Greens, Fennel, Lemon, and Dill

Bring 950ml water, 475ml broth, barley, and 1 scant teaspoon sea salt to boil in large pot. Reduce heat to medium-low, cover, and simmer until tender, about 40 minutes.

Meanwhile, heat 2 tablespoons oil in heavy medium skillet over medium-high heat. Add onions, sprinkle with sea salt, and sauté until golden brown, stirring often, about 15 minutes. Add sautéed onions and remaining 1450ml broth to pot with barley. DO AHEAD: Can be made 1 day ahead. Cool, cover, and chill. Rewarm before continuing.

Add kale and chard to soup. Simmer until greens are tender, about 15 minutes. Add spinach, spring onions, dill, fennel fronds, and mint; simmer 5 minutes. Add 1 tablespoon lemon juice. Season soup with sea salt, pepper, and additional lemon juice, thinning with more broth, if desired.

Divide soup among bowls. Sprinkle feta cheese over, drizzle with oil, and serve.
