There are over 900 different varieties of onion, but for our delicious White Onion Soup, you only need one type! White onions have a sharper flavour and work extremely well blitzed in a soup.
We’ve used white onions in this recipe which can be harder to find than standard brown cooking onions, but it’s worth finding them; most large supermarkets will stock them, but you can use brown if you can’t find white onions.
We love a warming, comforting soup for lunch on a chilly day. This White Onion Soup is creamy and velvety, with a strong flavour.
It’s also suitable for freezing so why not rustle up a big batch and pop in the freezer ready to defrost on those days you don’t have time to start from scratch. Don’t forget the wholemeal roll for dipping!
What diets is this White Onion Soup suitable for?
The following ingredients can contain allergens so be sure to swap them for gluten free and/or vegetarian diets.
- Stock pots
As always, take extra care when cooking for people with allergies and be sure to use different utensils, cookware and preparation areas.
Do you need any special ingredients to make White Onion Soup?
We’ve used white onions, but you could use brown if you can’t find white ones. Half fat crème fraiche can be found in the dairy aisle at most supermarkets.
For a perfectly smooth soup, we’ve used a stick blender to keep it quick and easy!
