Classic French Onion Soup

When I was a little girl, my daddy lived in Birmingham, Alabama. As a confirmed foodie, he faithfully explored every restaurant he could find, and the area was blessed with a profusion of great places to eat. I loved my visits with him because we would eat out at every meal, fostering the fledgling foodie in me.

Being the 70’s, quite a few restaurants had what they considered to be a somewhat French influence, and there was French onion soup everywhere. I went through a period of ordering it every time I saw it, having fallen absolutely in love with the tang of gruyere, the buttery lusciousness of the toasted cheese, the salty bite of parmesan, and the silky sweetness of caramelized onions. It wasn’t long though, before I realized that French onion soup recipes varied tremendously, and that there were places where it was to be avoided. On the other hand there were French onion soup recipes that were to be courted – savored and celebrated.

It took somewhat longer for me to realize enough about food to distinguish why some were very good, and others weren’t worth washing a dish over. In the end I realized it came down to three elements; the onions, the broth and the cheese. Like many of the most delicious things in the world, classic French Onion Soup is a study in simplicity. This is a prime example of treating each ingredient exactly right, and asking them to talk to you. At each step, pretend you are coaxing a shy date, and your French onion soup will reward you with a conversation in the end that’s unparalleled. This dish isn’t quick, but it’s extremely simple, and while a couple of steps take some time, none of them take much attention or work. In the end you’ll have an authentic French onion soup that is bursting with flavor, complex, layered and more fabulous than you could believe. I love great food, but I hate fussy food, and this is just about the perfect embodiment of that!

To make this soup absolutely fabulous – the kind of fabulous that makes you close your eyes and make little ‘mm-hmm’ sounds – you’ll need to pay attention to three tricks. Make sure you take the time to allow your onions to fully caramelize with the herbs. The full, rich sweetness can’t be rushed. You don’t have to hover over it though – do something else, come back every few minutes, give it a stir and it’ll do its thing.

Try to use homemade beef stock. I make almost all of my own chicken stock, and a majority of the beef broth I use. If you must use commercial stuff, spring for the best you can buy. It’s a major flavor component, so this isn’t the place to skimp. The no skimping rule applies to the cheese as well. Because so much of this dish is so incredibly inexpensive, use your budget on good cheese. Look for a great Swiss, Gruyere, Emmentaler etc. Under no circumstances use the pre-sliced Swiss cheeses – you may as well just pour your soup down the drain if you get that chintzy. A piece of good cheese can run about $10, so it’s not something you’d buy every day, but since the entire pot – enough to serve 8 people, costs about $15, I spring for the good stuff, even as stingy as I am with the food budget normally.

Give this classic French Onion Soup a try – you’ll be surprised at what fabulous, authentic flavor you can get with such easy, accessible ingredients!

How to Make Classic French Onion Soup

  1. In a Dutch oven over medium heat, melt butter. Add onion, garlic, bay leaves, thyme, salt and pepper. Cook for approximately half an hour, stirring occasionally, until the onions are soft, deep golden brown and very fragrant.
  2. Add the red wine, and simmer until the wine has evaporated, about 10 minutes more. If you’d like, toss the bay leaves and thyme sprigs. (I usually forget, so I’ve made a game that whichever kiddo gets the bay leaf gets to make a wish).
  3. Carefully sprinkle the flour over the onions, a bit at a time, stirring well, until all of the flour has incorporated. I like to use a mesh strainer to really sprinkle it on without lumps. Reduce heat to low, and cook for about five minutes or so. Stir in beef broth.
  4. Bring the pot to a boil, reduce to a simmer, and season to taste with salt and freshly cracked black pepper.
  5. To serve, preheat oven to 350F. Slice the baguette into 1 inch slices, and toast baguette pieces for about 10 minutes, or until very dry. Turn oven to broiler.
  6. Place1-2 baguette slices into each bowl. Ladle hot soup over the top of the bread. On top of the bread, sprinkle a generous handful of the Gruyere, and sprinkle with the Parmesan. Carefully place bowl under the broiler, and broil until cheese is golden brown and bubbly.

      Hey Karen! Thank you so very much - I love provolone as well - anything that involves toasty cheese is great in my book! Tell your husband I'm very sorry about his garlic issue ;-), but I'm so glad you found a recipe you love!

      I have made this recipe of French Onion Soup twice. My husband, Leon, and I love it. I almost followed it exactly, I halved the amount garlic, because my husband is not a garlic fan, I used provolone cheese and French bread that I cut up and toasted into cubes like croutons, this makes the bread easier to spoon up. We love this so much, I will not be trying any more recipes because this is our recipe from here on out for French onion soup.

      I just LOVE French onion soup. Your recipe looks outstanding. I cannot wait to try it. Bubbly, toasted cheese, broth-soaked baguettes. Oh my goodness! I think I will go ahead and make some baguettes just so I can make this recipe!
