Classic Bistro French Onion Soup |

It’s important to understand that french onion soup is not a complicated dish. It’s actually very simple to make. Most versions don’t include any cream or cheese and instead use a combination of broth and beef stock, which can range from a light version to a rich, meaty version. This recipe uses both; it’s a delicate balance of flavors that is both comforting and savory.

French onion soup is something you never forget. It tastes so rich, yet light at the same time. It is sweet and savory with a hint of spiciness and onion. The following recipe, though, is not the classic French onion soup recipe you will find in every French restaurant. This recipe is more of a rustic French onion soup.

You can’t make a French Onion soup in your home when you have no idea how to prepare an onion soup properly. Do you know how to make a French onion soup?

I was one of those geeks who got hooked on cooking quickly and began purchasing cookbooks to learn all I could about it. I soon discovered that I like American and traditional French food. I don’t have the knowledge or time to make great French cuisine (though I did spend hours learning how to tourné vegetables, which is useless in my day-to-day existence), but I was drawn to Anthony Bourdain’s Les Halles cookbook because it offered approachable traditional French cuisine. One of my favorites was a recipe for French Onion Soup, which I’m delighted to have recreated here.

Dark caramelized onions in a savory broth are topped with a cheese-encrusted french bread crostini and fresh herbs in this traditional soup.

The loss of Anthony Bourdain shocked me, which surprised me since I’d never felt anything like that before when a celebrity died. But I was a fan of Bourdain, and he is one of my culinary idols.

I first had escargot and pigeon at Les halles in New York, I saw him give a lecture with Jaques Pépin, I’ve read all of his books and seen all of his programs, and I got an autographed copy of his most current cookbook Appetites for my birthday last year.

Because this is the kind of cuisine that reminds me of Bourdain, I was overjoyed to remember about my Bourdain encounters while preparing this recipe.

Is it simple to prepare French Onion Soup?

Yes, this is definitely true. This is a more upscale soup that is surprisingly simple to prepare. Without any tricks, a novice chef might prepare this and end up with a great dinner to wow their friends.

The longest step is caramelizing the onions, which isn’t difficult but does take some time. If you don’t want to use wine, just leave it out of the recipe and add additional broth to get the desired consistency.

Onion Caramelization Techniques

Making caramelized onions calls for low and slow cooking. This process will change white crispy raw onions into sweet, brown, soft onions that are full of flavor. Place onions in a large dutch oven over medium-low heat. Add butter and season with salt and pepper. Let cook for 40 minutes, stirring occasionally, until the onions are deep brown in color. Stir in stock to deglaze the pan and create a saucy texture.
