Instant Pot French Onion Soup

French Onion Soup is a hearty and easy dish to prepare your guests when you use the Instant Pot. Not that it isn’t hearty when you don’t use your Instant Pot, it just tastes better when it isn’t such a long process, ya know?

Can this be frozen?

Yes, it can be frozen. You will want to freeze after step 8, keeping the soup separate from the baguette and cheese. It can be reheated later by thawing fully in the refrigerator or placing the frozen soup into a pot with 2-3 cups of beef stock (#1041 base) and bringing it to a boil. Once heated, you can add the bread and cheese.

The combo of a flavorful broth, caramelized onions, thyme, and crispy baguette slices topped with melted cheese make this french onion soup a real crowd-pleaser.
