Caramelized Onions, Three Ways


The onion, author Jim Harrison once remarked, is one of God’s more perfect creations. I couldn’t agree more. I don’t know what the afterlife holds in store, but if there are no onions when I get there, I’m going to miss old Earth. One of the most amazing things you can (legally) do with an onion is caramelize it.

Wikipedia informs me that caramelization is a complex, poorly understood process that produces hundreds of chemical products and equilibriates anomeric and ring forms. iphone 8 case red edge I don’t think they are referring to the ring shape of an onion slice, either. The important thing to understand is that onions, cooked for a very long time over low, even heat, miraculously metamorphose from a crunchy bitter vegetable into a sweet, chewy, beautifully coloured one. In order to caramelize properly, you cannot allow the onions to stick and burn, which requires constant vigilance. best case iphone 8 A little blackened bit here and there is okay, but what you are wanting is amazing transition of a huge pile of white matter into a small pile of deep reddish brown matter. I like to read a book and sip from a glass of wine while I do this, preferably with some jazz in the background (I favour Branford Marsalis’s Eternal, for autumn evenings). Caramelized onions are required in dozens of dishes. Why then do so many recipes completely fail to address the issue of how to cook them? Most recipes, even by authors of the ‘Slow Cooking’ school, tell you something like “sauté the onions for at least thirty minutes.” Now, technically, that is accurate, but extremely misleading. A correct direction, such as the one I will give you here, is “sauté the onions for two whole hours, standing over the stove the entire time like an anxious parent.”

Caramelized onions are the basis for the three simple dishes given here: onions shreds, balsamic onion sauce, and French onion soup.

You will need:

a lot of brown onions. At least five.

Slice the onions finely! It isn’t so hard with a sharp knife. Just peel an onion but leave the root end untrimmed, which keeps all the layers together. iphone 8 mum case Cut it in half, and then pare it away like a deck of cards. Note that five large yellow onions will produce a veritable mountain of slices. You might wonder how many people this will serve. Well, after cooking for two hours, you will be able to fit those onions into a single cup (it serves two).

Put the onion slices in a colander, lightly sprinkling salt on them and separating the segments. Through the miracle of osmosis, the onions will start to weep their liquid. Go away and leave them in private for a good quarter of an hour. Put down a layer of paper towels on a big cutting board, dump the wet onions on, layer more paper towels on top, and press out the liquid.

Heat a good splash of olive oil and a good chunk of butter in a big cast iron pot until the butter melts. I like cast iron because it allows even diffusion of the heat, preventing burning. iphone 6 case apple official This is important over long cooking times for something as fragile as an onion. Put in the onions slices, tossing them around to get them coated with oil. Keep the heat low – your patience will be rewarded. We don’t want a loud sizzling as the onions go in. Then cover the pot and leave it for twenty minutes. When you return and uncover them, you will find the onions have given up a lot of moisture. At low heat they will continue to do so for about an hour (uncovered).Onions (1)

First the onions will release moisture. Stir them occasionally.Onions (2)

Then they will wilt. Add a pinch of sugar to give the natural sugars the right idea.Onions (3)

Then they will turn brown. They need constant stirring now to prevent burning.Onions (4)

Then, finally, they will turn a beautiful red-brown. elephant iphone 7 cases You are done!

Onion Shreds

These are simplicity itself, but to make them, you will need to push caramelization like you’ve never pushed it before. Just keep stirring until those onions are the color of oxblood. They should be sizzling lightly all over. Then take them out, and drain them on paper towels. They will dry crunchy. Use them as the tastiest garnish imaginable for a side of lentil and rice gruel. (I’m sorry, that should be pureé, not gruel. Where are my manners?)

Balsamic Onion Sauce

I cup caramelized onions

2/3 cup balsamic vinegar

¼ cup sugar

salt and pepper

For this one, add the sugar way back when the onions are starting to wilt. This will definitely make them caramelize faster. When the onions are brown and dry, add the vinegar. Put the heat way down, cover it, and let it simmer an hour. Season with salt and pepper, then drizzle it over steak and potatoes. iphone 7 plus head case It will keep a month in the fridge.

French Onion Soup

Before stumbling upon this recipe (I think it was from John Thorne, probably in the indisputable work of genius Outlaw Cook, but I couldn’t swear to it), I suffered through numerous bowls of lackluster French onion soup. I think I kept trying various recipes out of sheer peer pressure: it was so famous, I felt I had to enjoy it, despite the evidence (like Wii bowling). Anyway, as a good recipe will do, once I read this one, I understood the point behind French onion soup. It was demystified in a sudden flash of comprehension. iphone 6 plus liquid glitter case This recipe differs from all of the other recipes out there on one simple, fundamental point: how to cook the onions. When they are browned to the point of extinction, then you can make true French onion soup. It is good, I swear. I have fed it to teenagers and they went back for more.

Once your onions are caramelized, add three cups of beef stock. I made real beef stock for this, which is another thing I like to do on autumnal days when nothing else is going on, but I’m not above pouring it out of a box. The onions will plump up again, but this time full of savory stock, not bitter juice. Simmer on very low for another half hour. Check the seasonings, but it should be perfectly salty by now.Onions (5)

Toast some slices of French bread on one side (I do it under the broiler, as I don’t have a one-sided toaster. My parents used to have one when I was a kid, though. It sort of flipped the bread around when you opened it to check what was causing all the smoke). You’ll need three or four slices per bowl.

Just before serving, add a dash of dry sherry to the soup. This will brighten it. Ladle the soup into good, deep bowls, put the bread on top toasted side down, and sprinkle with grated gruyere.

  • The french onion soup looks to die for. Bajeezus.

    I got a little lost in the onion caramelizing instructions. Is this right? Cover on low for 20 minutes. Uncover and continue on low. Add a pinch of sugar when they wilt. Begin stirring after they begin to turn slightly brown. Once two hours has passed, you are done.

    Is there no lid covering after the initial 20 minutes? Is there no stirring before the slight brown?

  • lambykins

    mmm, mmmmmm!!!!! that sounds awesome. i wish i had the patience….. :( oh well. maybe my sugar plum will make me carmelized onions????

  • Thanks, Chris. I clarified it a little. Yes, you leave them uncovered after the first 20 mins (so the liquid can evaporate off). You do need to stir them throughout the process, but not constantly until near the end.

  • Matt

    a spectacular post, Daniel. veritable worship, and my mouth was watering. I’ve already got a couple soups planned this weekend, but I’ll put this one on the list for the upcoming week. Thanks!

  • Thanks. We are going to make your squash soup this weekend.

  • Last time I visited the USA I kind of did what I do everywhere I go: try and taste everything I can get my hands on. And as good as many things were, the thing Ive been meaning to learn to do ever since is french onion soup. I loved it and its the only thing I actually ate more than once while on that trip (in Gallagher’s and in Rosie O’Gradys, both in NY). I have a few recipes stored but none really sound like the thing I remember. Yours do but I have a question; Is there a version in wich you also have a whole (not sliced) onion braised/stewed into the soup? As I said, I only had it twice but one of them (Gallagher’s I think) had a delicious soft whole onion under the thick layer of cheese.

    Mouth watering here too…

  • That sounds pretty amazing, but I have not heard of this recipe. I searched online a bit, but I guess Gallagher’s is being coy about their trade secrets… something to do when I make it to New York!

  • Joal

    I am making the balsamic onion sauce right now. Man it smells nice. I decided to go a bit crazy and add a couple of anchovy slices at the same time as the sugar, and kind of mash it all in. I’ll let you know how it turns out.

  • Joal

    It’s finished, and now I have a very small container of concentrated onion sauce in my fridge. It tastes yummy. I’ll be trying it with dinner tomorrow.

    Finally ate this tonight… on kangaroo steak, with a beetroot and walnut salad and steamed broccoli. And a glass of shiraz. It had a terrific rich flavour that enhanced the steak really well. I’ll be making this one again!

  • Mmm… kangaroo. I wonder if I can find that here?

  • I keep using up my onions before I can make soup, but I’m caramelizing some right now…for a thyme wheat crust pizza, no sauce, loaded up with the onions, mushrooms, bacon, and cheddar and mozzarella and provolone, to be washed down with Pipeline beer. I’m giddy for the first bite!

  • I’m also caramelizing the onions in bacon grease, something I thought you might appreciate. :D

  • Joal

    Oh onion-loaded pizza… splendid idea.

    Well I see your bacon grease suggestion and raise you… I’m going to caramelize my onions in duck fat next time. Or maybe goose fat!

  • Hi does nyone know if you can store caramelised onions easily as I know you can buy them so it stands to reason you can store them in a glass jar???

  • Hi Catherine. I don’t know about glass jars, but you can certainly store the onions shreds described above in the freezer, in a plastic freezer bag. I’m not sure how long they’d keep, as I always eat them right away.

  • Thanks for that, and for any readers that are having difficulty chopping onions without the tears, here’s an incredibly easy tip – put them in the fridge for a few hours, then chop them straight away after taking them out! No more tears! I found some more onion soup recipes here if anyone wants to try some more recipes.
