This blog post will teach you how to fry onions for the perfect burger. We’ll also give you some tips on what types of onions to use and how long to fry them for.

What type of onions to use for frying

The first step is to choose your onion. For this recipe, we recommend using a yellow onion. They have a milder flavour than white onions, so they won’t overpower the taste of your burger. Once you’ve selected your onion, it’s time to start chopping. Other options are red onions and white onions.

Next, heat a tablespoon of oil and butter in a skillet or frying pan over medium heat. Once the oil is hot, add the onions and stir to coat them in the oil and butter. Then, let them cook, stirring occasionally. Continue cooking the onions until they are golden brown and caramelized. This will take about 10-15 minutes, so don’t rush.

Once the onions are cooked, remove them from the frying pan, add them to your burger, and enjoy!
