Asparagus and Spinach Soup

Serves 4 | Prep: 10 mins | Cook: 25 mins

Ingredients

  • 6 asparagus spears, chopped into quarters
  • ½ bag fresh spinach
  • 1 medium potato, peeled and diced
  • 1 medium onion, chopped
  • 4 cloves garlic, minced
  • Zest and juice of ½ lemon
  • 50g butter (or olive oil)
  • 1 litre vegetable or chicken stock (made from 1 cube + boiling water)
  • 250ml cream (or dairy-free alternative)
  • Salt to taste

👩‍🍳 Step-by-Step Method:

 

💚Step 1, Preparation:

  • Vegetables: Wash the asparagus and trim the tough woody ends. Chop the spears into bite-sized quarters. Peel the potato and dice it into small, uniform cubes (this ensures they cook evenly). Finely chop the onion and mince the garlic.
  • Aromatics: Grate the zest from half of the lemon. Squeeze the juice into a small bowl and set aside.
  • Stock: Boil your kettle. Crumble the stock cube into a measuring jug and pour in the boiling water, stirring until fully dissolved. Keep this warm.

💚Step 2, Building the Flavour Base:

  • Melt the butter in your soup pan over a medium heat. Listen for the gentle sizzle; you want the butter to foam slightly but not turn brown or burn, which would add a bitter taste.
  • Add the onions. Cook them gently for 5–7 minutes, stirring occasionally, until they become soft, translucent, and sweet.
  • Toss in the asparagus. Sauté for about 3 minutes to seal in the fresh flavour.
  • Add the garlic and lemon zest. Stir constantly for just 1 minute. Tip: Garlic burns quickly, so keep it moving!

💚Step 3, Simmering to Perfection:

  • Add the diced potatoes to the pot. Fry them for 1–2 minutes to coat them in the buttery onion mixture.
  • Pour in the warm stock. The liquid should just cover the vegetables.
  • Bring the pot to a gentle boil, then immediately reduce the heat to low. Cover with a lid and let it simmer for 10–15 minutes.
  • Check: Pierce a potato piece with a fork; it should slide in effortlessly. If it’s still firm, give it another 5 minutes.

💚Step 4, Withering the Spinach:

  • Once the potatoes are tender, lower the heat to the minimum setting.
  • Add the spinach in handfuls. It will look like a lot, but it will shrink rapidly. Stir gently for 1–2 minutes until the leaves have completely wilted.

💚Step 5, Blending to Silkiness

  • Crucial Step: Turn off the heat. Ensure the soup is not bubbling vigorously. Blending boiling hot liquids can cause dangerous splatters.
  • Use a hand blender to puree the soup directly in the pot. Move the blender up and down slowly until the texture is perfectly smooth and velvety. No chunks of potato or asparagus should remain.

💚Step 6, The Final Touch:

  • Stir in the cream, lemon juice, and a pinch of salt. The cream will help thicken the soup, while the lemon juice cuts through the richness with a bright, tangy kick.
  • Return the pot to low heat (mark 3) for 5 minutes with the lid on. This allows the flavours to meld together and the soup to heat through gently.

💚Step 7, Taste and Serve:

  • Go ahead and taste your soup. Blow on your spoon! (It’s easy to forget how hot the centre of a creamy soup can be).
  • Taste and adjust. Does it need more salt? A little more lemon? Remember, add salt in tiny increments (half a teaspoon at a time) to avoid over-seasoning.
  • Serve piping hot in deep bowls. For an extra touch, drizzle a little extra cream or some olive oil.

💡 Chef’s Notes & Variations:

  • Vegan Option: Swap the butter for olive oil or a vegan butter alternative and use coconut milk or oat cream instead of dairy cream.
  • Storage: This soup keeps well in the fridge for up to 3 days. The flavours often taste even better the next day! Just reheat gently on the stove, adding a splash of water or stock if it has thickened too much.

 

Enjoy your homemade masterpiece! 💚
