A cup of something lovely…

I love this recipe. I tried it only as an experiment and I was amazed by the results. It’s simple to make and full of goodness but it tastes complicated, unusual and delicious. I absolutely love it. And to think I make this with cooked beetroot…

The inspiration for the soup came from this recipe. I was looking for an easy recipe with ingredients I had to hand and as I was searching through various different ingredients I came across Beetroot and orange soup with mustard seeds. I love orange, I love mustard, but until this recipe I was fairly iffy about beetroot, so I decided to add more mustard and orange. I didn’t realize how much flavour the fried orange zest adds – and it really is what makes this something special – but I like the gentle sweet sourness the fresh orange juice give this version. Also I love the smell and taste of the onions and garlic simmering in melted butter, orange juice, a little orange zest, some mustard and a little white wine vinegar. I was actually worried that adding the beetroot would ruin it but, and I was amazed, it made it even better.

The quantities below make about 7 – 8 ladles of soup. Because it’s so flavourful a small bowl of about 1.5 ladle portion is quite satisfying. It makes for a good starter or, if you pair it with a scone or simple sandwich, it makes for a delicious light lunch.

Mustard seeds are not always that easy to find in your local supermarket so if you can’t find them just top your bowl of soup with a little wholegrain mustard and finish with a sprinkle of fried orange zest. I’ve updated the recipe to include just wholegrain mustard rather than mustard seeds as it is easier and I actually prefer it that way.

I mentioned in a previous recipe about beetroot’s reputation for purifying the blood and improving the health of your liver. What I neglected to mention is that it is also good for lowering blood pressure and it contains a mineral called silica which helps your body make use of calcium, meaning it helps keep your bones strong and so helps prevent osteoporosis.

Beetroot, Orange & Mustard Soup

Makes 7 - 8 ladles full of soup.

Serves: 4

Beetroot, Orange & Mustard Soup


  • 50g salted butter
  • 1 large onion, sliced
  • 2 large garlic cloves, crushed
  • 1/2 teaspoon dijon mustard (generous)
  • 1/2 teaspoon wholegrain mustard (generous) + more for topping, if using
  • 1 medium-large orange, zested and juiced (strained)
  • 500g cooked beetroot, chopped
  • 500ml vegetable stock
  • wholegrain mustard


  1. In a deep saucepan, melt the butter on a gentle heat. Once melted add the onions. Stir around well. Cover and leave to cook for 2 minutes.
  2. Stir in the garlic. Increase the heat a little, cover and leave for a further 5 minutes.
  3. Stir in half the orange juice, the white wine vinegar and a quarter of the orange zest. Cover and leave for a further 5 minutes.
  4. Stir in the beetroot and mustard. Then pour in the stock and bring to the boil. Reduce heat and leave to simmer for 8 minutes.
  5. Remove the soup from the heat and blend to a fairly smooth consistency. Leave for 5 minutes to cool a little.
  6. While the soup is cooling you can fry the orange zest. Use a non-stick pan with just a tiny spray of sunflower. And fry for a minute or two on a moderate heat.
  7. With the soup still warm but no longer piping hot, stir in the rest of the orange juice.
  8. Ladle into small bowls or cups and top with a little wholegrain mustard and finish with the all important fried orange zest.
