Method

  1. Step 1

    Begin by placing a large saucepan over medium heat and adding in the olive oil (1 tbsp).

  2. Step 2

    Next, roughly chop the onions (4 onion) and leeks (1) and add them into the pan.

  3. Step 3

    Add a pinch of sea salt, give them a stir and leave them to cook until the onions (4 onion) are transparent and soft.

  4. Step 4

    Now, peel the cloves of garlic (4 garlic), cut them in half and add them into the pan. Cook for a further 2 minutes.

  5. Step 5

    Next, add in the vegetable stock or chicken stock (600 ml) and cook for 15 minutes.

  6. Step 6

    Take the pan off the heat and blend until smooth using a stick blender.

  7. Step 7

    Place back onto the heat and stir in the cream along with a pinch of salt and black pepper. Taste and adjust the seasoning if needed to suit your taste. Feel free to swap out the double cream (100 ml) for any dairy-free cream or milk alternatives.

  8. Step 8

    Tip - When I'm seasoning I generally always use sea salt. In fact, from the wide variety of sea salt brands on the market, my favourite is the Maldon Salt Company. The reason I prefer this brand is, of course, because of the pure and natural taste, but also because the sea salt crystals are still made by using traditional artisan methods. The Maldon Salt Company is a family-run business dating back to 1882 here in the UK.

Questions people ask

How long does creamy onion soup take?

About 32 min from start to finish, of which 15 min is prep and 17 min is cooking. That figure is worked out from the method rather than timed with a stopwatch, so give yourself a little more the first time.

How much does this make?

The original recipe did not state a yield, so nothing has been invented for it. The scale control on the recipe card multiplies the quantities instead, which is the honest version of the same thing.

Can I see the ingredients in ounces and pints?

Yes. The metric and imperial switch on the recipe card converts every quantity, rounded to amounts you can actually weigh or measure rather than to four decimal places. Your choice is remembered for every recipe on the site.
