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, 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.

How to Stop Onions Making You Cry

I have found the only way tears don’t stream down my face while chopping onions is to put them in the fridge for an hour before I cut them. It’s not always convenient, but when I am making something that calls for SIX onions, it is the only way to keep my fingers safe!

How to Make Instant Pot French Onion Soup

*Detailed and printable recipe is available at the bottom of the post. Slow cooker instructions are down there too!

Melt the ghee using the Saute function on the Instant Pot, and add the onions and 1/4 tsp of kosher salt. Stir occasionally until browned (15-25 minutes). Some of the onions might stick a bit, but keep pushing everything around to deglaze the pot.

Allow for 5 minutes of a natural release and then flip the valve to perform a quick release. Discard stems from the thyme and the bay leaf. Serve and try not to let the “mmmmmmm” sounds everyone is making distract you from your own bowl of soup.

Pro Tips/Recipe Notes

  • If you’re not Whole30/Paleo/dairy-free, feel free to add some grated cheese to the top of your bowl and soup and stick that bad boy under the broiler. Gruyere, provolone, and swiss are all yummy options.
  • Use 1 tsp dried thyme instead of fresh.
  • Not Whole30/Paleo/Gluten-free, you can sub in Worcestershire sauce for the coconut aminos, and all-purpose flour for the arrowroot powder.
  • If you don’t eat beef you can use chicken bone broth in lieu of the beef stock.

  1. thank you for this recipe! made it tonight SO easy and SO delicious. PS- i used soup bones from a costco rotisserie to make a chicken broth in my instapot FIRST and THEN made this with that. LOVING IT!

    • Making stock in the IP is one of my favorite things, so I LOVE that you did that! My husband calls it “garbage water” because it’s made from scraps. But it’s such a great way to stretch food and reduce waste.

  2. Just made this last night with home made beef bone broth and it was SO good! Making it again for lunch today :)) Thanks for the recipe!

    • Vicky, I’m so glad to hear that, and I bet the homemade bone broth made it extra special!

      Thanks so much for taking the time to leave a review. 🙂

  3. Is there  something i can dub the ghee for to make it compatible to AIP? No dairy allowed in the elimination phase

  4. This is AMAZING! It’s so silky and delicious.

  5. I absolutely LOVE French Onion Soup but never want to use wine. This recipe looks perfect- thanks!
