Onion Peeler

How long does it really takes to caramelise onions?

Food writers have been misleading the public on the time it takes to caramelise onions for years. Many recipe websites such as the Washington Post Food, Indian Cooking and even the Recipe Writers Guild state that caramelising onions takes around 5 to 10 minutes. Most readers who have attempted this have either come out with soggy or burnt onions, leaving many dissatisfied.

Meal recipes should be taken with a pinch of salt most of the time but the difference between the quoted 10 minutes and the actual cooking time (around 45 minutes) is somewhat less accurate than most misjudgements. Caramelised onions should be started at the top of a recipe due to their cooking time, but we have found the most convenient method is pre-preparing them the day before or even preparing them overnight in a slow cooker.

To prepare caramelised onions in a slow cooker, add thinly sliced onions to the bowl, drizzle melted butter over the top of them then toss them with a spoon to make sure they’re properly coated. They should then be cooked on low for 8 to 10 hours, with occasional stirring.

To speed up the traditional method of cooking, start with a dry pan and only add oil or butter once the onions have softened. This should be around 10 minutes quicker than using a ‘wet’ pan, but the truth is that properly caramelised onions take time.
