French Onion Soup is one of my favorite soups, especially when the temperatures outside drop – even just a little.

There’s just something so very comforting about breaking through the cheesy, French bread exterior to get to the delicious brothy soup underneath!

It has always been one of those soups that I would look forward to having at restaurants, but wasn’t one I knew how to make at home when we first married.

It wasn’t until our third Christmas together that I tried my hand at making it. We were hosting the soup course of a Christmas progressive dinner and my husband requested it. It turned out perfectly and continues to be a go-to recipe for me.

To make French Onion Soup, you’ll want to begin by caramelizing your onions. You’ll start by slicing your onions thinly and adding them, along with your salt and butter to your Dutch oven set over low heat. Stirring occasionally, you’ll let your onions cook until they have cooked down and are dark and caramel in color, about 45 minutes to an hour.

Once your onions have caramelized, add in your garlic, beef stock and wine (or chicken stock, if you prefer) and simmer for another 30 minutes.

When ready to serve, ladle your French Onion Soup into oven safe bowls arranged on a baking sheet. Then top with slices of French bread and top with grated cheeses. Bake in the oven until the cheeses have melted, about 8 minutes.

  1. This is one of my husbands all time favorite soups….and I have NEVER made it. I feel like such a bum!!

    That’s it…I’m making this one. It’s happening.

    So thanks, from my husband 😉

  3. One of my favorite soups. Hubby prefers when I use half yellow onions and half sweet onions so the flavor isn’t too sharp (but I suppose a pinch of sugar would work too). I also add just a little bit of dried thyme towards the end of cooking the onions (along with the garlic).

  4. I can’t any of these people made, at least the stovetop version because nobody questioned the “olive oil” mentioned on the first line of instructions on how to make the soup.

    What about that “olive oil”?

    1. You need oil to sweat and caramelize your onions. Butter is fine but a mix of olive oil and butter helps the butter to not burn. Kind of basic cooking knowledge. 

    1. I hope you enjoy it, Nick! It’s sooo delicious – my family loves it!
      They are from Staub – I love using them! I’ve had them for a little while, but hopefully you should be able to find at any of their retailers.
      Thanks!

  5. Yes – wondering about the Olive Oil too mentioned on the directions of making the soup – how much olive oil or is it in replacement of the butter??
