These golden-brown caramelized onions are such a tasty topping or add-in ingredient for so many things. Anything from salads to dips to burgers to sandwiches gets a flavor upgrade from these onions. The possibilities are endless!
Have you ever ordered something in a restaurant that was topped with caramelized onions and thought I’d love to try making these at home but it seems so complicated?! Well despite that thought, or what you may have heard, caramelized onions are really pretty easy to make. They simply require a nice big pan, a bunch of onions, a little bit of butter and sherry, and quite a lot of patience!! Follow these easy steps to create the perfect golden-brown caramelized onions every time!
You start with a bunch of sliced onions – I always use at least one whole onion, but usually two or three if I’m planning a number of recipes for the week that use them. The onions cook down quite a bit, so one onion doesn’t make as much as you may think it might.
Next, you melt the butter in a wide low pan – this Le Creuset is one of my favorites. I prefer an enamel coated pan so you get a nice fond – the brown bits – to form on the bottom of the pan. Scraping the fond into the onions while they cook makes them especially yummy!!
Once the butter melts you toss the onions in, give them a good stir to coat them with butter and let them start cooking. Then – this is where the patience comes in – just let them just sit and cook for about 20 minutes. No stirring! Just walk away, well not too far away, and leave them alone for those long 20 minutes. After 20 minutes they should be starting to turn just slightly brown on the edges.
After 20 minutes stir them a couple of times and scrape any brown bits starting to form off the bottom of the pan. Set the timer and let them cook for another 15 minutes. Once they’ve been cooking for a total of 35 minutes add the sherry and scrape the bottom of the pan thoroughly. Stir them one more time and then let cook for another 10 – 20 minutes. Keep an eye on the onions as they continue to cook, they will go from partially golden brown like below to fully golden brown pretty quickly.
Total cooking time is determined by what you want to do with them, and how hot your stovetop gets. I cook them for about 45 minutes, so on the lighter side for soups, dips and tarts. I cook them for about 50 – 60 minutes when I’m going to use them for burgers and sandwiches or salad toppings.
If you want various degrees of doneness, remove some of the onions from the pan after about 45 minutes and let the rest keep cooking!
If you want to make a big batch during your weekly meal prep, you can actually freeze caramelized onions. Putting them in an ice tray is a great way to keep small portions on hand!

Notes
Your onions are gorgeous! My range cooks too hot, even on low, to make caramelized onions, but I make them in the slow cooker, instead. Whatever it takes!
Thanks! That’s a bummer about your range getting too hot but love that you’ve found a workaround with the slow cooker!
i need to make a large batch and have them handy…it makes everything taste so much more delicious!
When I was in college, I had an older woman once tell me that if I couldn’t cook, I should learn how to make excellent caramelized onions so that when my spouse came home from work, he would think I cooked even if I ordered out. Even though I cook very well, she was right about the impact of the aroma of caramelized onions – and knowing how to make them well is crucial! Thanks for the tips about freezing them!
I love that story!!
I love the addition of Sherry! What a fabulous idea!! I love caramelized onions on a steak! What a great recipe here! Great tips!!
Thank you for the step by step photos! So good to see what it’s supposed to look like during the process. That Le Cruset pan you’re using is a dream!
Wow, I never knew to leave them for that long without stirring. I always stir them and that’s probably why they never turn out right. Thanks for correcting a long-standing wrong.
These sure do look like the perfect golden brown caramelized onions. Thanks for the lovely tips!
I love caramelized onions, but I have never tried adding sherry to it. Its sounds like it would be a delicious addition
Oh I can imagine how incredible those onions are…they look amazing!
Freezing caramelized onions in a ice tray? Brilliant idea! I will try it !
Love these onions! They look amazing. When I worked in restaurants we used to make 12 kilos at a time! These days I’m making them on a much smaller scale!
