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.

  • Press "Saute" and let the Instant Pot heat up until it says “hot”.
  • Melt the butter 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.
  • Add the garlic, and cook for 1 more minute.
  • Sprinkle flour over the onions and garlic, and cook for 2 minutes, stirring often.
  • Deglaze the pot with the 2 tbsp sherry, and add: 6 cups beef broth, 2 tbsp Worcestershire sauce, 2 sprigs thyme, and 1 bay leaf.
  • Lock the lid into place and set the steam release handle (valve on top) to “Sealing”. Press Manual>High Pressure>5minutes. 
  • 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. 
  • Place oven-safe bowls on a baking sheet.
  • Fill each bowl with soup, and top with 1 slice of French bread, 1 slice of provolone cheese, and ¼ cup of grated gruyere.
  • Place the baking sheet under the broiler set to high for 1-4 minutes, or until the cheese is lightly browned and bubbling. Watch carefully so that it doesn’t burn.
