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

Crockpot French Onion Soup I

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!

Crockpot French Onion Soup I

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…






Crockpot French Onion Soup I

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.

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.

    The company who started this campaign eventually became the world’s largest soap company. There are two ways to go about this, firstly, change your diet and secondly use some natural products that help adjust your sugar levels without the side effects. It is necessary for us to figure out effective ways to solve this tough trouble.

    If you’re going to use it for cooking food for yourself only, then you can choose a small electric model that will be enough for that purpose. You can also ensure your vegetables are done at precisely the same time as your steaks. Get rid of the debris that is clogging it and test the igniter again.

    Legume includes navy, kidney, string, black, and pinto beans,
    chickpeas (garbanzo beans), lentils, carob, licorice, and
    peanuts. In less sunny or cloudier climates the skin manufactures vitamin D at a diminished rate,
    which can also cause seasonal depression for many people in these areas.
    Wheat happens to be quite abundant in both lectins and gluten, and
    research has shown that there is a connection between
    arthritis and an intolerance to both of these substances.

    What do you think will happen if I just throw all the ingredients in the pot and set it to low before running out the door? In case I hypothetically read “throw it in one pot and forget it” and then neglect to read all the directions until I scroll down a bit to check the type of cheese… Is it ruined?

      After reading all the comments i am not doing this recipe. The orginal recipe that this came from is different. This recipe has switched the red wine with beer, and doesnt have brown sugar in it and has bay leaves in it.

      I was going for the original(tyler florence recipe) but now im going for this recipe!

      La Madeline’s French Onion Soup Ingredients

      1 Tbl extra virgin olive oil
      2 medium onions, peeled and thinly sliced
      1 whole bay leaf
      1/4 Tbl freshly ground black pepper
      2 cloves garlic, chopped
      1/2 tsp dried thyme
      1 quart beef stock
      2 cubes bouillon
      1 quart water
      1 french baguette; sliced and toasted
      3/4 cups gruyere cheese, grated

      Heat the extra virgin olive oil in a heavy, large saucepan. Add onions, bay leaf and pepper. Saute mixture over low heat for about 30 minutes, stirring occasionally. While onions are cooking, dissolve boullion cubes in 1 quart of water. Cook the onions until they caramelize, and have a beautiful golden brown color. Add garlic and thyme and stir well. Cook for two minutes.

      Pour beef stock and boullion mixture into the pot and bring to a boil. Reduce heat and simmer for 30 minutes, covered. When ready to serve, prepare ovenproof soup bowls on a baking sheet.

      For an extra rich treat, I like to sprinkle gruyere cheese in the bottom of the soup bowls. Ladle soup into the bowls, place a slice a baguette on top of the soup and sprinkle with gruyere cheese. Place the baking sheet under a broiler to melt the cheese and brown the top. Serves 4.

        sounds great I have some giant strawberry onions,and maybe some uncle johns hot sausage .

    Neutrino — February 9, 2014 @ 11:20 pm

    Do yourself a favor and actually caramelize the onions in a sautée pan first. They WILL NEVER caramelize in a slow-cooker. (Onions excrete water when cooking. Water boils at 212°F, far lower than the caramelization temp of fructose (230°F), or sucrose (320°F). As such, the temp cannot get much above 212° until the water has vaporized and departed. This cannot happen when the lid is on.)

    Beyond the profound incompetence of instructing readers to do what is not permitted by the laws of physics, I have high hopes for this recipe.


    • Ella — June 20th, 2014 @ 1:17 am

      Mine caramelised just fine :)


    • Kim S — December 2nd, 2014 @ 1:33 am

      That is why you cook them in the pot with no liquid for the first hour – you pompous ass.

    • jrcc — December 29th, 2014 @ 11:03 pm

      Actually I carmelize onions in my slow cooker. Slice up a 5# bag of Vidallia onions into the slow cooker with a stick of butter and T salt. Low temp 12 hours perfect carmelized onions. Divide and freeze.


      • JMR — February 22nd, 2015 @ 5:24 am

        Yep. I do the same thing. Carmelized the onions overnight in the slow cooker, than added broth and the rest the next morning. Voila!

    There are so many different types of beer. Which one did you use and it might explain why someone had a disappointing result. Would be grateful for the name or type of beer you used . Thank you.

    This is the best recipe I have ever done for FO soup! My husband requests it all the time! It’s sooo easy and cheap to make ! Makes restaurant FO soup totally forgettable & not worth it , especially since they charge so much for a teeny tiny bowl. I’ve added my thing to it (we are huge pepper and RWvinegar fans ) but overall, it’s the way to go as far as FO soup goes for us! Thanks Tyler !
    I love this recipe !

    Brian — November 24, 2014 @ 10:44 pm

    Normally I would not post on a recipe, but this one needs warning. Do not make this. There is a reason you can not just take a normal recipe and make it in a slow cooker.

    This soup lacks all depth. It is flavorless, and too sweet. The onions are tough, and do not caramelize in a slow cooker. So disappointed.

    Hungry — December 3, 2014 @ 1:59 pm

    I realize you posted this recipe a long time ago, but I’m hoping you’ll get back to me. I’d like to start this tomorrow morning and then go to work, which means it will be on low more like 10 hours (rather than your recommended 6-8). Would that be OK?


    • Mandy — December 3rd, 2014 @ 10:30 pm

      It worked fine for me to do that! Just make sure you take the time to caramelize the onions first, either with the crockpot (60 minutes) or in a separate pan and add all the buttery goodness to the crockpot (much less time – maybe 20 minutes).

    Where did you get those dishes to bake the soup in? I love how they have a little handle :-)


    • mary knutson — February 9th, 2015 @ 2:17 pm

      Try looking for the soup bowls at Bed, Bath & Beyond. I’m pretty sure that Old Time Pottery has been also, if you have one in your town. I’ll bet Carsons, Macys, etc. have them too. It’s always a nice presentation to serve in those neat bowls.

    My fiance and I love this recipe! I can’t believe some people said they chucked theirs! I’ve made this recipe a lot and it has always worked out to be awesome! I’m glad I found this on pintrest! Thanks for the great recipe!!!

    Kristin — February 16, 2015 @ 7:17 am

    Snow is coming and cant wait to try this recipe tomorrw. Question: If carmelizing the onions on top of the stove would you still add the brown sugar to the liquid base of the soup or omit totally? Thanks!


    • Jessica — February 16th, 2015 @ 7:27 am

      i’d probably omit – add it to the onions and just add the entire contents of the pan to the crockpot!


  19. #
    Michele Allen — April 23, 2015 @ 7:50 am

    Very blah. Definitely needed some Worcestershire and maybe a bay leaf – if NOTHING else. Lacking in flavor completely without it.
