How to Make French Onion Soup in Instant Pot
- Set your Instant Pot to sauté mode. Add in oil and allow it to get hot, about 1-2 minutes.

- Stir in beef broth, Worcestershire sauce, salt, and pepper.
- Place bay leaves and rosemary spring in your Instant Pot and secure with the lid.
- Pressure cook on high for 5 minutes. Let your pot naturally release pressure for at least 15 minutes after cooking.
- Release any excess pressure and remove the lid. Remove herbs from the pot immediately.
- Preheat the broiler on your oven to high and line a baking sheet with aluminum foil. Using oven-safe bowls, fill them with your french onion soup to about ½-inch from the top.
- Place bowls onto your prepared baking sheet. Top soup with a slice of bread, and shredded cheese.
- Broil for 3-5 minutes or until the cheese begins to bubble and turn golden brown.
- Serve immediately and enjoy!
French Onion Soup Recipes FAQs
Instant Pot French onion soup broth is made of a combination of beef broth, Worcestershire sauce, and caramelized onions. You can always swap out the beef broth for vegetable broth for a vegetarian French onion soup.
Wine is optional to use for deglazing the pan and adding additional flavor to the soup. I've made my French onion soup recipe without wine, but you could always go for a Pinot Grigio, Sauvignon Blanc, or Chardonnay. A dry white or red wine is best for French onion soup!
