How To Make French Onion Soup

This soup begins with onions.

Since this french onion soup recipe yields a single serving, I use one small onion.

In truth, the size of the onion doesn’t completely matter. It could be small or it could be medium – in the case of french onion soup, the more onions the better.

Step 1

The onion is sliced into thin strips and added to a small saucepan with melted butter.

The onions caramelize which means that as the onions slowly cook, the natural sugars in the onions release and result in a wonderful sweetness that will transform any dish they are added to.

The process of caramelizing onions takes a little bit of time, for this soup recipe I recommend cooking the onions for 25 minutes.

Step 2

After the onions have caramelized, add in a little red wine and cook it down.

Then add in a little flour to thicken the soup, and then pour in the broth.

Pro Tip: Another key ingredient to a good french onion soup is the broth. Typically, french onion soup is made with beef broth but good store-bought beef broth is hard to come by. I’ve found that most packaged beef broth has a slightly “tinny” taste. Instead, I use chicken broth. It makes the soup perfect every single time.

Step 3

Make sure you don’t leave out the glorious chunk of cheesy bread which is, in my opinion a complete necessity in french onion soup.

Traditional french onion soup calls for Gruyere cheese and I highly recommend it. Gruyere is rich, it’s smooth and it melts easily.

What To Do With Leftover Wine

Leftover wine…is there really such a thing?

Sure, you could always pour a glass for yourself and sip on it while cooking or relaxing. But what if you only use wine for recipes?

If that’s the case, you can freeze wine by pouring the wine into plastic ice cube trays and placing the trays in the freezer. When you want to use a little wine in a recipe, pop out one of the frozen wine cubes and add it to your recipe.

Instructions

  • Melt the butter in a 2-quart saucepan over medium heat. Add the onions, garlic, thyme, salt and pepper and cook until the onions are very soft and caramelized, about 25 minutes.
  • Add the wine, bring to a boil, reduce the heat and simmer until the wine has evaporated, about 5 minutes.
  • Sprinkle the flour over the onions and stir. Reduce the heat to medium-low and cook for 10 minutes, stirring occasionally so that the flour doesn’t burn.
  • Stir in the chicken broth and bring the soup back to a simmer, cook for 10 minutes.
  • Taste and add additional salt, if necessary.
  • Heat the broiler. Place the slice of French bread on a baking sheet. Sprinkle the Gruyere cheese over the top and broil until bubbly and golden brown, 3-4 minutes.
  • Place the bread in a soup bowl and pour the soup over the top.

  1. I made this today with madeira for the wine (all i had) and better than buillion organic beef stock. omg. it was delicious! I doubled it cause even tho i am one person I knew I would want another serving in the next two days. Thank you so much for your work here, it is changing the way I cook and eat!!

  2. QCan your one-serving recipes be doubled for two? I need to include my husband. Most of the recipes on Pinterest are for at least four people, and we aren’t that good at eating leftovers. A two-serving meal would be perfect.
