What Are the Best Onions For French Onion Soup?
To develop the deep flavor that the soup is known for, you’ll want a strong onion. For that, I usually use a mix of red (we all know they’re really purple. Lies!), yellow, and white onions.
Having used sweet onions in the past, I do not recommend them as I think it throws off the flavor profile. Adding in a shallot or two is always a great way to develop the flavor even more.
Pro Tips/Recipe Notes
- If you don’t want to use wine, sub in 1 tbsp of apple cider vinegar.
- If cutting onions make you cry, put them in the fridge for 30-60 minutes prior to cutting them.
- Use 1 tsp dried thyme instead of fresh.
- If you don’t eat beef you can use chicken stock in lieu of the beef stock.
- The saute function on some Instant Pot models can run really hot and burn the onions. Reduce the level on saute to “normal” or “low” if your model runs hot.

This was so easy to prepare and so delicious! Using my mandoline slicer helped with the onion prep and using minced garlic from a jar. I used Apple Cider vinegar and my broth was left over from a roast and potato dinner. I’m kind of a semi-made from scratch cook 🙂
