What Are the Best Onions For French Onion Soup?

To develop the deep flavor that this soup is known for, you’ll want a strong onion. For that, I usually use a mix of red, yellow, and white onions. If I can only use one, it is red 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 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 bone broth in lieu of the beef stock.
