Why Do You Caramelize Onions for French Onion Soup

You need to caramelize the onions to add depth and flavor to the soup. This step is what gives French Onion Soup that rich and savory flavor. See my How to caramelize onions recipe.

It takes time to caramelize onions but you can skip this step and just add all your onions to the instant pot. You will not get that deep flavor like at Panera’s or restaurants. Most of my soup recipes are a dump and go but for this Instant Pot French Onion Soup, it makes a huge difference to make your onions ahead of time.  You can carmelize your onions on saute in the instant pot or do them right on the stovetop.

    1. Hi! This looks great, but I am not a fan of wine. I understand it changes the flavor, but what is something that I can replace the wine with. I’m one of those that can spot wine the moment it touches my tongue, and I just hate it, LOL. Thanks!!!!

    2. Please tell me the serving size of the French onion soup. Is it 1 cup(8 oz) or 2? I count my carbs.

    3. You should make sure you say brown sugar and not just sugar in your recipe. Just wasted an hour trying to get the onions to caramelize.

    4. I have this in the pot now and it smells so good. I did have trouble getting my onions to caramelize in 30 minutes and after about 35 I increased the heat on the stove top. Maybe I had too deep of a pan?? Can’t wait for this to be ready though! Thank you for the recipe!

    5. I made this and it was very good, just a bit on the sweet side. Is there a way to cut that down? Should I made put in a bit of salt?

    6. I would not recommend using cooking wine for anything. It is just wine with a bunch of salt added. Use real wine and control your own salt input. I will make this in the near future.

    7. 5 min cook time and 5 min prep time, yet the directions call for 30 mins to caramelize onions, 5 mins in the pressure cooker and 2-3 under a broiler. Not to mention the time to cut all the onions and gather ingredients.

    8. I thought it ended up too sweet, I wouldn’t add the sugar at all next time. We’re a vegetarian household so we use fake beef broth- but otherwise super simple and a delicious meal.

    9. I made this as a first try of my Instant Pot. It was very easy. It did take a little longer to get the onions caramelized. I did add a little Worcestershire Sauce after, it was a little too sweet for me. Thank you for posting the recipe, it was a hit.
