French Onion Soup (of sorts)
Some recipes shouldn't be fiddled with. When simplicity is best, modification means degeneration. Perhaps this is never more true than when it comes to caramelized onions, beef stock, red wine and a crouton. It seems unthinkable that French onion soup could ever be improved. And since it's so easy to make, there's no reason to deviate from the mainstream at all. At all! Whereas some staples of the bistro menu are quite toilsome to prepare at home (pommes frites, for example), French onion soup operates on the opposite end of the work-to-reward index as a simple dish that always delivers. That's probably why it was one of the first things I loved cooking. Even with little experience or technique, the sublime virtues of an impeccable French onion soup were immediately within reach. So why corrupt it, even a little?
I'm sentimental about lots of things, but food isn't typically one of them. And yet, this time I feel like I'm bludgeoning something I truly love. But I gotta. I guess somewhere around the 543rd time I made French onion soup, I got tired of something. It's too heavy, too onion-y, too much of one (very good) thing. And the cheese always burns under the broiler, which is cool to some people, but less cool to clean up. So I wondered if a bit of balance might make the onion shine even brighter. I thought of carrot: mild flavor, great color (which this hoary specimen could use) and not too much of anything else to blot out the onion. And then I thought I'd tone down the onion a bit, too, by going with shallot instead. I figure shallots are more pungent, have a finer texture and are lighter than onions. They also caramelize a lot quicker (thanks to their small surface area, I suppose). And there you have it, the makings of a new-school French onion soup (of sorts). To do this the old-fashioned way, just use onions and leave out the carrot.

If you've never done this before, you probably need a lot more shallots/onions than you think you do. By the time you cook them down, you'll be left with about a quarter (or so) of the volume that you started with. That's a guess, but the point is that these guys will disappear on you. So put a bunch in even though we're trying to lighten things up. I probably add about a cup of raw chopped shallot per serving. Check the video for the visual.
Then caramelize the shallots. I mean really. They need to be about as close to burned as possible, without, of course, crossing the line. Something like a milk chocolate color--deep brown--is what you want. Some of the edges on a few shards may even go over to the dark side. That's ok since deep cartelization is absolutely essential. A big pot with lots of surface area on the bottom will help--something like a sauté pan is a good idea. Season as you go with salt and pepper. I noticed that my shallots got there in about 15 minutes (two servings), much quicker than when I've used onions.
Once the shallots are close to fully caramelized, add the half-inch dice of carrot. Your call on how much, although I'd say you need about the same volume of raw carrot as you have caramelized shallots (if not more). Move them around the pan and let them get a bit of color before rolling in with the liquids. You can add a few (go light) shards of beef at this point if you have some to use up; it's a good addition, though not of the essence.
As for the liquids: start with beef stock and follow up with a few good glugs of red wine. Dust it off with a few sips of balsamic. Season with salt and pepper and allow the liquids to reduce on a medium simmer for at least 15 minutes, but preferably longer.
You'll know it's done when it tastes right. I like some sweetness from the aromatics, and palpable body from the stock and wine, too. I guess balance and body are the key terms here. It should be full flavored, so keep reducing if the taste remains too thin. You'll know when you're there.
Traditionally, you pour the soup into an ovenable crock, top with a hunk of bread, utterly overwhelm with cheese, and then slide the whole deal under the broiler. And this works. But an easier way to do it is to slice a baguette lengthwise, place the bread on a cookie sheet, top with Gruyere or Emmentaler Swiss, and bake until the cheese melts. A vegetable peeler is good for shaving off thin slices of cheese. Easier cleanup, lighter food, similar cheesy result.
