Black Barley With Mushroom Broth

This nourishing black barley with mushroom broth is a sophisticated vegetarian dish that celebrates deep, earthy flavours and contrasting textures. By soaking the black barley overnight, you achieve a delightful chewiness that pairs perfectly with the umami-rich broth made from mushroom stems and the grain’s own soaking liquor. It is a vibrant, colourful bowl that feels both indulgent and remarkably clean, making it a wonderful choice for a weekend lunch or a restorative midweek dinner.

Packed with fibre and plant-based goodness, this recipe is a fresh take on a classic grain bowl. The addition of spicy kimchi and a silky soft-boiled egg provides a modern, Asian-inspired twist that elevates the humble barley to something special. For the best results, use the freshest mushrooms you can find and serve the broth piping hot to gently warm the raw garnishes.

Ingredients for Black Barley With Mushroom Broth

  • 240ml black barley

  • 12 crimini or white button mushrooms, stems and caps separated

  • 4 bay leaves

  • 1 tablespoon kosher salt, plus more

  • 4 large eggs

  • 1 small red or watermelon radish, trimmed, thinly sliced

  • 1/4 cup kimchi, thinly sliced

  • Small coriander sprigs and olive oil (for serving)

Place barley in a medium bowl and add 725ml cold water to cover. Cover and chill at least 12 hours.

Drain barley, reserving soaking liquid. Bring barley, mushroom stems, bay leaves, and 5 cups water to a boil in a large saucepan. Add 1 tablespoon salt, then reduce heat and simmer very gently, stirring occasionally, until barley is tender and liquid is almost completely evaporated, 80–90 minutes. Drain and transfer to a rimmed baking sheet to cool. Pluck out mushroom stems and bay leaves and discard.

While the barley is cooking, bring a medium saucepan of water to a boil and gently lower eggs into boiling water. Cook 6 minutes; transfer eggs to a bowl of ice water with a slotted spoon and let cool. Carefully peel; set aside.

Thinly slice mushroom caps and place half in a medium saucepan with reserved barley soaking liquid. Bring to a boil, then simmer until soaking liquid has taken on mushroom flavour, 10–12 minutes. Season with salt. Strain through a fine-mesh sieve into a medium bowl.

Divide barley among bowls. Top with radish and remaining sliced mushrooms. Cut eggs in half lengthwise and tuck into barley, yolk sides up. Nestle kimchi next to eggs. Pour mushroom broth over, dividing evenly. Garnish with coriander and drizzle with oil.

Barley can be soaked 1 day ahead. Keep chilled.
