Types Of Onions To Use
I recommend using yellow onions (also called brown onions) for this recipe. It caramelises well and has a mild flavour compared to red onions, this mild flavour is great for not overpowering the other flavours in your burger or hot dog.
You can of course use red onions or white onions if you like, I’ve used red onions to make this delicious homemade red onion chutney. You could also mix and match types of onions for a variety of tastes and flavours.

Quick Caramelised Onions
Making caramelised onions doesn’t need to take hours, this recipe takes just 15 minutes including the time needed to slice the onions.
I add balsamic vinegar and brown sugar, this combo makes your fried onions turn brown and nicely caramelised. It’s only fried for a few minutes to make the texture tender, slightly crispy and far away from being mushy.
How Much Onions To Use
I used 2 onions for this recipe, one was large and the other was a small to medium sized onion. So, I decided to weigh them to give you an accurate measurement.
Together they both weighed 334g which is the equivalent of using two medium-sized onions which usually weigh between 150g to 200g.
Below are the few ingredients needed to make these caramelised onions:
- Butter & Oil: Oil is needed to fry the onions and butter adds additional flavour. You can use only oil if you don’t want to use butter.
- Onions: I recommend using yellow onions (brown onions) for this recipe, if you want, you can use red onions or white onions though the final taste will differ.
- Balsamic Vinegar: A dark concentrated vinegar which adds a tangy, smoky and sweet flavour.
- Sugar: I like to add dark brown sugar or light brown sugar, it adds sweetness and helps to brown the onions. Adding sugar is optional as onions do have natural sugars within.
Feel free to add salt and black pepper to taste, I personally feel that the caramelised onions taste perfect without salt or pepper, so I didn’t add it to this recipe.
How To Cut An Onion For Hot Dogs & Burgers
First things first, make sure you are using a sharp knife as this will make cutting an onion fairly easy.
When making caramelised onions, I like to slice the onions into thin lines (remember, the thinner you cook the onions the quicker they take to cook).
I start by peeling the skin and cutting the onion in half, then I lay the onion flat side down. The onion is then cut into fine long strips. If you want, you could also dice the onion into small chunks. However, for traditional hot dog and burger fried onions, cut them into long lines pole to pole.

My Top Tips For Frying Onions
If you’re making these fried onions for hot dogs or burgers in particular, then I recommend you make these caramelised onions in advance or at the same time as when you’re making the burgers. This will prevent the burgers or hot dogs from getting cold whilst you are making the onions.
Cook the onions on a medium heat or even at a low to medium heat if you want to be cautious. If the temperature is too high, then the onions will burn too quickly and this will alter the taste and texture.
Use a non-stick pan to prevent the onions from sticking to the pan.

How To Store
If you have any caramelised onions leftover, then you can keep it in an airtight container and store it in the fridge for up to 3 to 5 days. That’s why you can also make this dish in advance!
You can also freeze this recipe too! To freeze, simply place the cooled caramelised onions in an airtight container and keep it in the freezer for up to 3 months. Place the onions in the fridge to defrost when you are ready to eat it.
When making hot dogs the onions are fried on a medium heat until tender and soft. They can also be caramelised by adding sugar and balsamic vinegar to the fried onions. This makes the perfect addition to hot dogs.
Usually, burgers made at a BBQ have caramelised onions on it but you can also add raw onions instead. Caramelised onions are sweet and slightly tangy whilst raw onions have a sharper onion taste and a crisper texture.
Caramelised onions are cooked on a medium heat, any higher can cause the onions to brown too quickly and burn.
