Set your Instant Pot to saute mode. Add in oil and allow it to get hot, about 1-2 minutes.
¼ cup olive oil
Add in chopped onions, and allow to sauté for 5-8 minutes, stirring occasionally. Your onions should be softened and have a little brown coloring to them.
4 large onions
Stir in beef broth, Worcestershire sauce, salt, and pepper.
8 cups beef broth, 1 teaspoon Worcestershire sauce, 2 teaspoon salt, ½ teaspoon black pepper
Place bay leaves and rosemary spring in your Instant Pot and secure with the lid.
2 bay leaves, 4 sprigs thyme
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.
2 bay leaves, 4 sprigs thyme
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.
6 slices French bread or baguette, 1 cup mozzarella cheese
Broil for 3-5 minutes or until the cheese begins to bubble and turn golden brown.
Serve and enjoy!

If you want to make this Instant Pot French onion soup vegetarian, you can substitute the beef broth for vegetable stock or broth. You can even substitute the cheese for a vegan option!
Don't have broiler-safe bowls? You can toast the cheesy bread separately, then add a slice to each bowl of soup before serving.
Using a sweeter onion is key for this French onion soup, but you can use white onions if that is what you have on hand.
Swap out shredded mozzarella cheese for gruyere, Swiss or provolone.
Slow cooker French Onion Soup? After caramelizing the onions, add all the ingredients into a crockpot and cook on low for 8 hours or on high for 4-5 hours.
