Onion Soup At Home

Onion Soup

Talk about iconic French foods and Onion Soup will surely come to mind at top of the list. It just happens that it’s also one of my favorite foods. I can’t make enough of it. And the more I make it, the more I love it.

On a trip to France, I ate plenty of onions soups, and it’s always a special thing to eat typical food in its birth places.

That’s me, in Paris.

But I have to say, there is nothing about this soup that cannot be replicated exactly at home. I’ve been making onion soup for so long in my home kitchen that I think I’ve mastered the recipe. Specially now, as this pandemic seems unending, traveling to France via the stove is the secret to life!

As simple as this soup may be, there are a few variables that impact on the results. First, the onions. You want to be patient and let the onions caramelize low and slow so that it flavors the soup — I talk about that in the recipe procedure, you will see.

Another important component is the liquid. Of course, you can use store-bought broth, but if you have the chance to make chicken broth, or buy the frozen version of brodo, (you can find plenty options nowadays), your soup will take you straight to France, in one quick shot. Bien sur!

The bread: any country bread will do, but if you have the chance to use a baguette, because of its thin shape, it will fit better in the soup bowl.

The cheese: my favorite for this soup is Gruyere, but Comte or any Alpine cow’s milk cheese will do.

The soup bowl: I have a couple of options at home, but the white soup bowl always wins.

Sometimes, I have the colossal courage to turn down the bread and cheese. It’s a way I have developed an appreciation for healthy eating defending my physical condition in the kitchen. Other times, my tolerance for fatty foods in the sake of kitchen travel is deeper that I know it myself.

For those on a diet: The onion and broth are so tasty that’ it’s still worth eating even without the bread and cheese.

When it comes to onions, feel free to use Spanish onions, yellow onions, or Vidalia onions, typical from Georgia. Spanish onions used to be imported from Spain and now they grow all over the U.S. They have a sweet taste and are perfect for all types of cooking. Yellow onions have a medium to strong flavor and are truly all-purpose. Vidalia onions are a bit sweeter than the two above. Any of those are good in this recipe.


Onion Soup

Serves 6


2 tablespoons olive oil

1 tablespoon unsalted butter

3 garlic cloves

5 large Spanish onions, peeled and thinly sliced

Kosher salt

Freshly ground black pepper

Freshly ground nutmeg

1 tablespoon all-purpose flour

½ cup dry white wine

8 cups chicken or beef broth

6 slices country bread, sliced

2 cups coarsely grated gruyere cheese


Cook the Onions: In a large Dutch oven pot, melt the butter and olive oil over low heat. Add the garlic and cook it ever so lightly, until it just starts to become a little golden, about 2 minutes. Add the onions, and cook, stirring frequently with a wooden spoon. Season lightly with salt, pepper and nutmeg and keep on cooking. This process is going to take a good 20 to 30 minutes. You don’t want to rush this step, or the onions will burn rather than slowly caramelize. The beauty of this soup lies in the caramelized flavor and color of the onions, so keep the heat at low or medium low at all times and stir very frequently.

When the onions are nicely caramelized, sprinkle the flour and stir for a minute or so to cook.

Add the Liquid: Pour in the wine and let it reduce by half.

Pour the chicken stock and let it get hot. Taste and season with more salt and pepper, if necessary. It probably will be necessary to add salt and pepper, especially if you use home made broth. If you use store-bought version, it’s the opposite; beware of the sodium component, and you might not need to add any more salt at all. Partially cover the soup and adjust the heat so that the liquid is just simmering; cook for 30 minutes. You can prepare the soup to this point up to 5 days before and keep it in the fridge.

Assemble the Soup and Top with Bread and Cheese:

When it’s time to serve pre-heat the broiler. Line a baking sheet with foil and have six deep ovenproof soup bowls ready to use. Carefully ladle the soup inside each bowl leaving some space for bread and cheese and place them all onto the sheet pan. Place a couple of bread sliced on top. (You don’t need to toast the bread.) and top with plenty of cheese over each bowl. Carefully transfer the heavy sheet pan to the oven and broil just until the cheese is melted and bubbling. Serve immediately.
