I love French Onion soup, but I don’t love having to stir the pot for 30 – 40 minutes not to mention having to wash the smell of Onions out of my hair. I heard that you can make this in the Instant Pot but I can tell you I was very skeptical. I love the Instant Pot, I use it for many recipes but I believe there is a reason to use it. Traditional French Onion soup is cooked low and slow in a heavy bottomed pot or dutch oven. Once the Onions are brown, flour and white wine are added and finally it’s enhanced with Beef stock. The soup is poured into oven safe ramekins and then topped with a slice or slices of toasted baguette and sprinkled with cheese. It’s then baked or broiled in an oven where the cheese melts over the soup. What’s not to love?
