Going to grill a burger later and i would like to put some caramelized onions on it. I just usually brown the onions in seasoning and add a little water and/or red wine if i have some open.

MY GF did it one time... Used a dutch oven and cut up the onions in ringlets and coated them in olive oil and salt.. Put the D.O. in the oven at 350.. When she smelled the onions took it and stirred them up and added OO if needed and put it back for not sure how long... It came out awesome... I could just eat a bowl of them...

There’s no shortcut. People will say there is, but they’re making something other than caramelized onions. Takes a long time, controlled heat, and stirring as needed.

I make a batch about once a month from a large bag of onions and freeze portions for future use.

1000x this. The recipe from Serious Eats has never failed me, and it puts the "shortcuts" straight, all in one place. I put a few shallots in the mix too. I never thought I would have eaten straight carmelized onions out of pan, but I sure have now. Once you make a batch, you can freeze the leftovers in an ice cube tray and pop out as needed, similar to this (they also make garlic and ginger in frozen pods):

This is true. I make a very good French Onion Soup and it takes a long time to caramelize the onions that form the base of the soup. Only after they are done do I slowly add my homemade beef stock and let that slowly simmer until it reaches the level of cooking I'm looking for.

I also make my own roux in batches of a quart at a time and caramelizing onions takes much longer than making the roux.

Butter or a little oil. I like to get my onions a little burnt. I love that taste.

Thin cut onions on a mandolin, butter in a black iron skillet. Sauté over medium heat, add salt & pepper, stirring constantly. When you get desired doneness, remove from heat, stir some more. Enjoy…

Butter and a bit of olive oil. Somehow the olive oil helps prevent the butter from browning too much.
S & P too taste
Finish with a little quality aged balsamic

Did a batch in a crockpot for an attempt at FO soup. Soup was all right, but I did really like the tast of the onions once they were caramelized. I've tasted caramelized onions at a fairly high end restaurant and they are delicious. I read a comparison of cp vs pc cooking for soups/broths, and though the pc won every time, the cp was lauded as being the best no-hassle way to caramelize onions (and was maybe its only use, therefore).

I like to add a little brown sugar at the end.

How come a lot of recipes will lie about how long it takes to carmalize onions. Usually I see stuff like this.

Carmalize one cup of onions (5 minutes)

No way, takes at least 20 minutes.

Any secret to freezing them? I've never done that, but it sounds like a good idea.

Large pot, butter and olive oil, salt, onions sliced

Cover the pot -critical step

Low heat

35-45 minutes and they’re perfect

Two ways either high heat, fast and add sugar to cheat the carmelization or I'll do low and slow on very low heat for a few hours. That gives the best flavor but takes so long.
Only do that of I'm Doing a ton of other things.

Mine take forever, but no short cut method has ever worked for me.

ATK has a recipe that adds a unique twist (which I've not yet tried) at the end:

"Instead of finishing with sugar or honey as many recipes call for, we added baking soda, which speeds up the reaction that converts flavorless inulin (a polysaccharide present in onions) to fructose."

After the onions are fairly well browned:

Combine 1/8 teaspoon baking soda and 1 tablespoon water in bowl. Stir baking soda solution into onions and cook, stirring constantly, until solution has evaporated, about 1 minute. Transfer onions to bowl.

Put them on the blackstone about a half hour before the burgers, or cheese steak meat. Gets them nice and dark.
