French Onion & Leek Soup
October 25, 2016 By Cathy — 20 CommentsRich, hearty broth, crunchy bread and gooey cheese make this bowl of french onion soup pure comfort food goodness.
You wouldn’t build a house starting with the roof right? To have a solid structure you need to start from the ground up. A solid foundation, sturdy walls and it’s not something that can happen overnight. Well, the same philosophy and patience are often needed in the kitchen too.
Have you been to New Orleans and tried the gumbo? It all starts with the roux, a combination of fat and flour that is cooked to a rich, deep brown and serves as the base. I love a gumbo where the roux is cooked for about an hour, allowing the flavors to develop and deepen. Sure, you could spend less time, but in the end your gumbo will be compromised. Good? Maybe. Great? Meh.
Well, we’re not making gumbo today (but boy, do I suddenly have a hankering). Today we’re tackling French onion soup.
When you think of French onion soup what do you picture? Melted cheese bubbling up over the edges of crispy toast? Well, that’s certainly part of it. But eventually you have to crack through that gooey exterior and dig your spoon into the soup. And it better deliver.
Listen, melted cheese and toasty bread are pretty much nirvana to me, so it’s a big deal to want to dig past it to get to something else. But with a little time and just the right combination of ingredients I got there. And yes, this soup is spoon-worthy.
The key to this soup is taking your time to properly caramelize the onions before adding the wine or stock. I like to get those onions all golden and soft before adding in the leeks, shallots or garlic. Once all of those are in the pot and browning up, it’s time for a little brown sugar and shot of vinegar. This adds a subtle sweetness and brings out the umami flavor.
From there it’s wine (I like white), stock (beef for me), fresh herbs (thyme and bay leaf) and finally a glug of port. Also, it’s so important that you season your soup from beginning to end. And taste, taste, taste! There’s no way to know if your seasoning is right unless you get in there!
Feeling inspired? Then it’s time to get building. And all the tools you’ll need for this masterpiece are a pot, knife and spoon! Enjoy!

I love your analogy about building a house and cooking. So true!! I definitely don’t mind spending time in the kitchen, taking a long time to make something. It’s my happy place and could totally spend all day in there….especially when the end result is something as tasty as this 😉 French onion soup is, without a doubt, a favourite of mine. Caramelized onions, white, herbs, cheese….what more could a girl want, right 🙂 ? Pinned, of course 🙂 !!
It’s what I enjoy the most about the holidays Dawn, days spent buzzing around the kitchen. Sometimes it’s better than the meal!
Every time I see the cheese and bread on french onion soup, I want to immediately rush to the kitchen and make some. Since it’s only 10 am though, I’ll wait at least an hour 😉 Great recipe and such beautiful photos!
Ha! Nothing wrong with soup for breakfast!
Wow, does this look good Cathy! It’s one of our favorites! This one is definitely spoon-worthy!
Spoon-worthy for sure Mary Ann! 😉

Nirvana. Carmelized. White Wine…. You hit all the right notes on this one. Feels like I transported to Fall just looking at your beautiful photos. Still hot and sunny here in Cali, but let’s pretend for an evening and join ya’ll in a proper cold evening’s meal.
Just dim the lights and crank the AC. Then it’s french onion soup time!
I LOVE how you compared a great dish to building a home! Great analogy, my dear! French onion soup is one of my favs (I’m pretty sure it’s one of everyone’s), and this looks AMAZING, Cathy! Seriously, I want to face plant into a BIG ole vat of this! LOVE that you added leeks! Your photos are just gorgeous and have me drooling all over the keyboard! Pinned! Cheers, friend!

OMG these look amazing Cathy! It’s still a bit chilly over here (summer hasn’t quite managed to break through) and I could just imagine sitting down with a warm bowl of this, complete with cheesy croutons. x
