Recipe to Make Instant Pot French Onion Soup

To make Instant Pot French Onion soup, you’ll need the following ingredients: 

French Onion Soup

Ingredients for Instant Pot French Onion Soup

  • 1/4 Cup Olive Oil
  • 10 Cups Thinly Sliced Yellow Onions
  • 1 tablespoon Brown sugar
  • 1/4 Cup Orange Juice
  • 1 1/2 teaspoons Salt
  • 4 Cups Low Sodium Beef Broth
  • 1 Teaspoons Worcestershire Sauce
  • 1/4 Teaspoons Freshly Ground Black Pepper
  • 1 Teaspoons Fresh Thyme Leaves
  • 2 Bay Leaves (optional)

Method

Here are the step-by-step instructions for making the best French onion soups.

Step One: Saute Onions

Turn on the saute function and add the olive oil. Once heated, add the sliced onions, brown sugar, and salt. Saute on low heat for 15 minutes, occasionally stirring until you have caramelized onions. Sautéing or sweating onions is one of the first steps to building a flavor base for soups.

Step Two: Deglaze Instant Pot

Add a little beef broth to the Instant Pot and scrape the bottom of the Pot to ensure there is no food stuck to the bottom of the Instant Pot. This will prevent the burn notice during pressure cooking.

Step Three: Add Ingredients to Pot

Add the orange juice, remaining beef broth, Worcestershire sauce, pepper, bay leaves, and thyme leaves to the Instant Pot.

Step Four: Pressure Cook French Onion Soup

Set the Instant Pot to pressure cook for 5 minutes on high pressure. Once the cooking is complete, allow the Instant Pot to release naturally. A natural release will prevent any liquid from spewing out of the top of the Instant Pot.

Step Five: Garnish and Serve

Pour the soup into bowls and garnish with your favorite toppings. You can add baguettes and cheese and place them under the broiler for extra flavor. This is one of my favorite French onion soup recipes.

Caramelized Onions

If you’re looking for the best onion for caramelized onions, you’ll want to go with either a white or red one. The caramelization process needs onions with a good amount of natural sugars, which these sweet onion varieties have in abundance.

White onions have a milder flavor and, when cooked slowly, will become sweet and deep golden. Red onions are slightly sweeter than yellow onions, so they may produce sweeter caramelized onions. However, both types of onion work great for caramelizing.

Lastly, remember that the size of your onions will affect the cooking time – smaller onions will cook faster than larger ones!

Green onions are much more tender than yellow or white onions and will become soggy when cooked in soups. Having said that, you will find green onions in Instant Pot Chinese Dumpling Soup and Instant Pot Egg Drop Soup.
