Since I gave you a 14 hour recipe yesterday, I figured today we’d make it a little shorter.

Crockpot French Onion Soup I howsweeteats.com

You know… like 9 hours.

But! At least this time you won’t have to cover your entire kitchen in flour, spend four days digging dough out from under your nails, scrub melted burned butter off the bottom of your oven and give the entire recipe you made to someone else because you can’t be trusted around it.

This time you can just throw it in a big pot and forget about it.

And drink beer while you’re at it. Winning!

I can’t believe there was a time in my life that I didn’t think I liked onions. I don’t even know how it is possible for someone who loves food to not like onions because they add a ridiculous amount of delicious flavor in so many different ways to so many different dishes.

And even though I used to think I didn’t care for them?

I still ordered french onion soup anyway. I’m sure you know why. The cheeeeese. And the bread. I distinctly remember sitting at a restaurant a few years ago and the server bringing one of our dining neighbors a piping bowl of soup with golden cheese just literally pouring down the sides.

All I could think was…

up

for

that!

For years after, I ordered french onion soup… and only ate the bread and cheese. I’d dig my spoon down in half way, grabbing a bite of toasted bread, a spoonful of broth, and strands upon strands of gruyere or gouda. I’d always finish everything in the bowl, except for the big pile of caramelized onions on the bottom.

I liked that set up. I liked it a lot.

Then, as I’ve detailed before – much like his Diet Mountain Dew habit, my husband developed an addiction to caramelized onions and asked for them on everything. Even weirdo things like pasta and eggs. I seriously think I made them nearly every day for three months. I first tried them on a burger, slathered in cheese and ketchup of course. Then we moved on to steak, and once I even put them in a salad… that sort of tasted good. Just don’t try it hungover.

Caramely onions? I could do this.

After all, if there was any vegetable for me to learn to love, it had to be the one filled with sugar that softened and sweetened easily and almost tasted candy-like at times, right? Right on.

Crockpot French Onion Soup I howsweeteats.com

So hopefully by this point I don’t have to do any convincing and we can let this cheese do the talking.

And if you stillll don’t like onions? Make this anyway and just eat the bread and cheese and broth like I did circa 1999. Totally worth it.

Crockpot French Onion Soup

[adapted from Tyler Florence]

makes a giant pot, about 8-10 servings

4 medium sweet onions, thinly sliced

3 garlic cloves, minced

4 tablespoons of butter

2 tablespoons balsamic vinegar (I used my favorite Fustinis!)

2 tablespoons brown sugar

3 tablespoons flour

8 ounces of beer

64 ounces of low-sodium beef stock

2 tablespoons fresh thyme

1/2 teaspoon black pepper

1/2 teaspoon salt

french bread

gruyere cheese, sliced

Set your crock pot on high, then add onions, garlic, brown sugar, butter, salt and balsamic and mix until combined. Cover and let cook for 60 minutes, stirring occasionally, until onions are a bit caramely and brown on the edges. Add in flour, then stir thoroughly and let sit for 5 minutes. Add in beer, beef stock, thyme, and pepper, then turn heat down to low, cover and cook for 6-8 hours.

Before serving, cut french bread or baguette into slices. Fill soup bowls to the top, then cover with slice of bread and a slice of cheese. Set under the broiler for 2-3 minutes, or until cheese is bubbly and golden brown. Be careful when serving as bowls will be hot!

Note: I used a very low-sodium beef stock, so depending on the stock you use, add additional salt for flavor if desired.

    This is awesome. Like you, I’ve been thinking about how I so despised onions as a kid, but love carmelized onions now. I’ve also been thinking about french onion soup. a lot. I don’t have the little bowls and I am a very, very, busy Mom so I love this idea of making it in the crock pot! I’m going to put the ingredients on my list for tomorrow now. Thanks!!!

      I’m cooking this right now! The onions are caramelizing. I’m also one of those who would order the stuff and eat around the onions. I remember my dad used to order it at the family’s favorite restaurant, every Friday. He always let me eat half the cheese off the top. My only problem is that every restaurant I’ve ordered it from since, it seems to be too salty, or too…something. To the point where, 3/4 of the way through, the flavor became, for lack of a better word, annoying. I like that you call for low-sodium broth, and i’m seriously hoping that this comes out tasting like what my dad used to always get. I’m excited! (i’m making this for their anniversary, by the way)

          Just finished it. It was delicious! I don’t have bowls that go into the broiler, so I ended up using a creme brulee torch to melt/brown the cheese. That seemed to work okay, but I’m thinking it’ll be better (and easier–as my thumbs can attest) with the broiler. I’ll get bowls for next time!

          I ended up salting mine just a little to counteract the sweet, but it was perfect that way! My dad, an avid souper, always taught me never to add much salt to soup–to always let each person salt to their own taste, so it was great! Thank you!

          • Emy — October 1st, 2011 @ 10:54 pm

    Is there a way I can make this without a crockpot? I don’t own one… Also I’m under 21 so I’m thinking of substituting ginger ale for the beer, what do you think? This recipe just looked soo much better than others I’ve seen..

    Reply

    • Jessica — October 3rd, 2011 @ 8:46 am

      Yep – I would saute the onions until caramelized in the butter – about 30 minutes or so over low heat. Then add the rest of the ingredients and bring to a boil, then simmer for about 2 hours. The ginger ale sounds like it would be pretty good, and you could also just use broth too. Let me know how it goes. :)

I did as Jess suggested to another review and I caramelized the onions on the stove and then added the garlic and flour for a few minutes. I then put everything into a pot to simmer for 1.5 hours. Yea this is ridiculously good. I’ve never made a recipe off this site I didn’t love! Thank you!!!

    I made this today. I agree that the longer the onions have to carmelize, the better the results. I used a oatmeal stout (we are dark beer lovers here) and it tasted delicious. I would suggest that readers not waste this great recipe by using any sort of light beer, you need a beer that stands up to the onions and garlic. Thanks for a wonderful dinner :)

      I think you could just use more broth, and I also think someone tried it with ginger ale and enjoyed it. You can also use wine, but I wasn’t sure if you wanted to do alcohol at all.

    If I could make a suggestion, put the thyme in a tea bag. Once done take the bag out and throw away, otherwise you will end up like me and have tons of thyme floating around in it. My only change to the recipe, since my family doesn’t mind thyme, but doesn’t want it floating in their soup.

    If you use stale bread and cut it up like croutons, they will soak up the broth better and are much easier to get out of the bowl.

    If you bowls don’t go under the broiler- put the bread slices onto a foil lined cookie sheet and add the cheese- put that under the broiler til the cheese bubbles- then float the cheese toasts in bowls of onion soup and enjoy ………(make an extra cheese toast for the cook)

    I made this recipe yesterday and it didn’t turn out as wonderful as I had hoped and I’m a HUGE french onion soup fan! I used coors light as my beer and I think that was a way wrong move, haha! Next time I think I will carmelize my onions longer, omit the beer and substitute with chicken broth and some worchestire sauce and LOTS more salt!! Altogether a very easy recipe, but just needs some tweaks for my taste buds.
    P.S. I got these wonderful french onion soup bowls from Sur la Table for $3.96 each! Love them!

    Just tried this recipe last night and it was great! Not quite the french onion soup that I grew up with, but very simple to make and delicious. There’s just one main thing I would tweak to make it perfect.

    One hour on hot in the slow cooker is definitely not enough time to caramelize the onions. I left them in there for almost two hours and they were still a little crunchy. I’m used to the onions being a step away from mush, but, if you like a little texture, than two hours should do. Next time I will cook them on the stove the night before and make sure that they are full caramelized and delicious! Overall great recipe!

    i am new to onion soup and to slow cooking.
    my husband is a huge fan of this soup and i really want to try this recipe.
    but i was wondering if onion soup freezes well, so i can double this recipe and freeze some for later. if it doesn’t freeze well, how long would it be good for in the fridge?
    also, i have a 5 and a half quartz, oval slow cooker. do i have to change the cooking time as well?
    thanks in advance.
