Slow Cooker French Onion Soup

For one thing I work full time and juggle 3 kids as well so spending more than 30 minutes in the kitchen preparing food just is not going to happen. Another thing, I’m cheap.

Ok you can call it frugal but whatever. I love making really easy cheap Crockpot recipes that everyone loves. AND it cooks by itself with just a little prep work from me. Bonus. Last but not least I HATE turning on my oven during the summertime.

Let’s talk a little bit about slow cooking shall we?? First off I have a few different varieties and I love them all. Each one has an occasion to be used like….

  1. This is my favorite 6 quart programmable one with a locking lid so it’s great for bringing to a potluck too.
  2. If you just want to serve a few appetizers you should get this one that sit side by side one another.
  3. I prefer not to use liners, but rather just spray olive oil inside before adding my food for easier cleanups.

Let me give you a peek of my pretty thang I bought recently. It goes with my kitchen so I can just leave it out on the countertop all the time. 😉

Can you make French onion soup in a Crockpot?

Yep, we will show you how. Where we used to live it got to 114 in the summertime and so there was no way I was paying more for air conditioning just because I wanted to make dinner.

For those reasons I rely on my slow cooker and Instant Pot pretty much nightly. Unless we’re having “whatever you want nights” which does happen when I’m just exhausted.

I started with a big batch of yellow onions that really needed to be used up. Some really like a mix of yellow, white and/or red onions but I use what is on hand. I hate wasting food so I got to searching what I had in the pantry to use them with. Threw in some beef stock, thyme and bay leaf with salt and pepper and tried this out.

  • If you’ve never had crockpot french onion soup it’s amazing! If you’ve had it but never thought of making it yourself at home it is the simplest soup ever to make.

You only need a few ingredients to boot too which is great. It is best if you have time to saute or caramelize onions first. If you just don’t have time for that, it will taste great just the same. Want to cook the onions first on the stove top to really generate more flavor, please do.

Using a baking sheet in the oven is a longer cook time but can be done if you’d rather. The reason to take this extra time to really brown this ingredient is to make the flavors more bold. If you’ve seen these that become a rich sticky brown color you can imagine the difference between these and raw.

Need it more low carb, just skip the bread part at the end. BUT that is most people’s favorite part so whatever….

Crockpot french onion soup recipe

  1. Onions – duhhhh, opt for yellow onions, sweet onions are another option
  2. Butter
  3. Beef broth
  4. French bread – day old is best
  5. Cheese on the top is what you would expect from the classic dish
    1. Gruyère is best but harder to find
    2. Otherwise you can always grab mozzarella and mix with some parmesan
  6. Spices
  7. Oven proof bowls are needed if you are going to do the bread with cheese on the top and melt
  8. Crock pot of course

So one thing you will need for finalizing this soup are oven safe bowls. If you want the traditional ooey gooey cheesy bread on top thee are a must and not really expensive.

Of course you could serve the soup as is out of your crockpot with a side of bread sliced. However topped with bread and cheese, then baked on a cookie sheet is part of the yumminess. I recommend doing it this way!

If you’re in a hurry you can make pressure cooker french onion soup too. I kinda’ cheated with this one and used cheeses I had on hand. It is nice that this method takes a lot less time though and you can use the saute function to brown onions at the very beginning. One pot meal that has fewer dishes to clean.

Pressure Cooker French Onion Soup

French Onion Soup Crockpot

  • Slice your yellow onions into rather thick / wide slices. Set aside. You can caramelize onions on stovetop with butter and a bit of red wine first for a deeper flavor. Turn crockpot on high and add onions inside spread out.
  • Add the broth, salt, butter, pepper, Worcestershire sauce and thyme.
  • Then cook on high for 7-8 hours or until it turns a darker brown color.

Get out your ovenproof bowls and fill them 3/4 full with soup from your slow cooker.

Preheat broiler to high or around 350 degrees. Put a thick slice of your day old bread on top of each bowl of soup,. Cover the bread with a mixture of mozzarella and parmesan cheeses (or traditionally used is gruyere). Put under broiler until cheese is melted and golden brown color, maybe 3-4 minutes.

If someone in your family is a no when it comes to a bit of “soggy” bread you could just serve some garlic bread on the side. Brown that separately with cheese on top and get a similar feel that everyone will enjoy.
