Roast Lamb & Barley Soup

Roast Lamb & Barley Soup

This Lamb & Pearl Barley Soup is the perfect answer to chilly evenings and lingering winter flavours, rich, comforting, and deeply satisfying. Inspired by Rachel Allen’s soulful broth, this recipe draws out the natural succulence of lamb and the gentle chew of pearl barley for a bowl that’s wholesome and delicious.

Ideal after a bracing walk in the hills or simply when you need a warming meal that nourishes as much as it delights, this soup is a fantastic way to transform good quality lamb (especially leftovers from a roast) into something truly special. With soft vegetables, aromatic herbs and satisfying grains, every spoonful feels like a hug.

Ingredients (serves 6–8)

  • 25g butter

  • 2 tbsp extra virgin olive oil

  • 2 medium onions, finely chopped

  • 2 celery stalks, finely chopped

  • 2 cloves garlic, crushed or grated

  • 1 bay leaf

  • 1 sprig rosemary

  • Salt & freshly ground pepper

  • 200g cooked lamb, sliced or shredded

  • 1 medium parsnip, peeled & chopped

  • 2 medium carrots, peeled & chopped

  • 100g pearl barley (or pearled spelt)

  • 1.25 litres chicken stock

  • 2 tbsp chopped parsley

Method

1. Warm the Base:
Melt the butter with the olive oil in a large pan over medium heat. Add onions, celery, garlic, the bay leaf and rosemary. Season with salt and pepper, then cover and cook gently for about 10 minutes until the onions soften.

2. Build the Soup:
Stir in the lamb, parsnip, carrots and pearl barley. Pour in the stock and bring to a gentle simmer. Cover and cook for 25–30 minutes, or until the vegetables and barley are tender and the flavours have developed beautifully.

3. Finish & Serve:
Remove the bay leaf and rosemary sprig, then stir in the chopped parsley. Adjust seasoning and ladle into bowls. Serve with crusty bread for a complete, soul-warming meal.

Serving & Tips

  • Serve with crusty bread or soda farls for dipping - perfect for soaking up every drop of the rich broth.
  • Leftovers taste even better the next day; flavours deepen after sitting overnight in the fridge.
  • For extra comfort, add a handful of chopped kale or spinach in the last 5 minutes of cooking.
  • Swap pearl barley for pearl spelt or oats for a slightly different texture while keeping it hearty.
  • Use leftover roast lamb to save time - no need to cook the meat separately.
  • Garnish with fresh parsley or thyme for a fresh herbal lift.
