Top tips for cooking with onions


Spanish Onions

The strongest in flavour and the least sweet of the bunch, Spanish Onions are a kitchen staple. Best used as a base flavour in any stew, sauce or soup, Spanish Onions should be diced or chopped roughly in order to get the most juice out of them.

Also Spanish Onions have innumerable health benefits for the immune system and allow us to recover from colds faster, due to the heated element of the flavour.

As far as I’m concerned an omelette just NEEDS a Spanish onion


Spring Onions

Though Spring Onions are quite mild in strength, they make up for it with the fresh, zingy flavour that is associated with spring. Always best when eaten raw, Spring Onions should simply be washed, chopped and thrown into a salad.  I just love them.



Of medium strength but incredibly sweet, Silverskins are not your average onions. Found raw in any good greengrocers, Silverskins are quite robust so have lots of uses. Being so naturally sweet, they are ideal for making chutney and jam, however when chargrilled they have a completely different flavour as soon as they caramelise.

I have never tried this [ersonal;l;y but it sounds good to me!

Chargrilled Silverskins can be left to cool, then enjoyed as part of a salad with the mixture of sweet and bitter tastes.



Shallots make for the perfect garnish or special addition to improve any standard dish. As they are almost as sweet as the Silverskin Onion, the best flavour of a shallot comes from roasting. Adam recommends pan-frying the shallots first then roasting them in unsalted butter for 15 minutes on 160° Oh my goodness these sound delicious!


Red Onions

Red Onions are one of the most versatile varieties of onion. Despite being very similar to the Spanish Onion in both strength and sweetness, Adam recommends eating Red Onions raw in a salad as an alternative to Spring Onions as they have a more heated tang.

My OH will not eat a salad without them.
