French Onion Soup Is One Of My Favorite Soup Recipes 

French Onion Soup is probably one of my favorites to order at a Steak House.

I love the depth of flavor you get from caramelizing the onions over a long period of time. But then again, I’m a sucker for caramelized onions in general. I could eat them plain! Then the richness you get from the beef stock combined with the onions and fresh herbs is comforting to me. But of course, you can’t forget the cherry on top! The baguette and melted cheese all over are the finishing touch to this classic soup!

It’s been a while since I’ve made it. But as I was sweating out the onions to get them nice and caramelized, it brought back all the feels.

This time around, things turned out a little different than they normally do.

The flavor was still great. But let’s just say I had a little mishap with the end product.

How Long Does It Take To Caramelize Onions For This Soup?

I love the soup making process. And it is definitely a process, especially french onion soup. It’s a labor of love because caramelizing that amount of onions takes about 40 minutes. But each ingredient you add along the way, adds another layer of flavor and more depth.

How To Assemble Classic French Onion Soup

By the time I had finished the soup I was starving. Hello.. pregnant… eating for two! I preheated my broiler, started slicing the bread and was trying to move quickly through my photo process so I could get to the eating part! 🙂

I brought out a baking sheet and placed my oven safe crocks on the pan then started to ladle my soup in crock. I carefully topped each crock with a slice of baguette and two slices of cheese. I gave them a kiss goodbye and said “I’ll see you in a little bit.” But really I just stood at the oven door watching as the cheese started to bubble and turn golden brown while filling the house with smells!

Because I was being a “helicopter mom” with my soup, I opened the door and tried to decide if I needed more cheese. After all the photos need to look amazing and more cheese usually helps with that right?

So I pulled the oven shelf out to get a better look. Left it open, walked over to get more cheese and CRASH!!!

French Onion Soup all over the oven door, the counter and all over the floor. Luckily I didn’t break any glass, which was a miracle. Cason came running and I just shouted. SHOOOOOOT!! Mike got off the phone and came running into the kitchen to see what all the commotion was. At this point Cason was asking me a zillion questions and all I could think was… I need to get these back in the oven so I can get my gooey cheese shot.

Such is the life of a food blogger! It’s all about the shot. Ugh.

So. I started to salvage what I had left and reapply the bread and cheese, while Mike worked on the floor. I wiped the oven door off and put the soups back in the oven. As soon as I shut the door I started to see French Onion Soup slowly start to run down in between the glass panels of the oven door.

Ugh… really!!! How in the world, did it get in between the panels!!

My Whole Family Loved This French Onion Soup 

I took a deep breath. Pulled the soups out, took my amazing photos then dove into the soup with my family. WHICH THEY LOVED!!!

And spent the rest of the night disassembling the oven door (which had 3 different glass panels… who puts three!!!), scrubbing them until the crusted cheese and dark brown onion soup came off and then reassembling the doors so we had an oven again. Needless to say. Next time I will be taking the baking sheet out of the oven to top it with cheese instead of leaving it in the oven with the oven shelf pulled out.

Even though my story is crazy. This French Onion Soup still totally hit the spot. It was everything I had hoped and dreamed it would be. Rich with flavor and so comforting, you get pops of fresh herb and then the buttery Gruyere cheese! I added a few surprise ingredients to give it a little tang that I know you’re going to love!

Bon Appetit friends!

    Hey! I made this recipe tonight but it turned out very light colored. How do you turn it a darker brown? Does it depend on the broth or how long you cook the onions? It’s very tasty and I’m lactose intolerant so used Violife Provolone to melt on top – yum! But my boyfriend says it’s not quite French Onion. Help!!

    1. Krista

      Hey Nicole, it does depend on how long you caramelize those onions. The browner the better, you could even add in bone broth which will give it a deeper beef taste. He might like that better.

    Good recipe but… for years I did this on the stovetop until my arm was tired. A few years ago found a recipe that caramelized ’em in a 400 ° oven. Spray dutch oven with PAM add butter, sliced onions some salt and cover. Cook 1 hour. Stir onions and scrape pot. Crack lid and go another hour, checking, stirring, scraping every 1/2 hr for the second hour. No tired arm and they’re perfect, usually at the end of 2 hrs. I’ve made onions to munch this way without even thinking of making soup!

    I’m sorry about the oven door, unfortunately totally relatable… However, loving the soup, looks very yummy! And the photos turned out great. Where did you get those crocks? They are super cute and goes so well with the rustic french onion soup. Well done!

    1. Krista

      haha.. thanks! I think I got them at Sur la Table, it was a while ago though but it’s also a classic of theirs so it may still be there!

    Those onions make me do a happy dance! I love this soup, but I’ve never made it at home! I need to give your recipe a go!
