Instant Pot French Onion SoupI’ve been craving caramelized onions lately and I couldn’t think of a better way to enjoy them then with this French onion soup. This tasty flavor-packed soup is all cooked in the pressure cooker. It’s super easy to make and only requires a few simple ingredients. It makes a great lunch or dinner in the fall and winter and will fill your home with a warm aroma. Instant Pot French Onion Soup

The only step that takes time is caramelizing the onions. They take about 15-20 minutes to fully caramelize so make sure to set time aside for the caramelizing part. After the onions are caramelized, a few tablespoons of flour, garlic, and the broth is then added.

I used College Inn® Beef Broth because it is deep and rich and has the perfect amount of flavorful herbs and spice. It takes the soup to the next level and adds several layers of flavor and the deep dark color that is a must in French onion soup!Instant Pot French Onion Soup After adding the broth, the pressure cooker is set for just 5 minutes because the beef broth is already complex in flavor and has already simmered for hours.  From there you can ladle the soup into small soup bowls, top with a slice or two or toasted bread and a sprinkle of cheese, broil for a few minutes and enjoy! Instant Pot French Onion SoupInstant Pot French Onion Soup
