Irish Twist on a French Classic! – Irish Onion Soup

On this St. Patrick’s Day, we are still in soup mode. Many years, by this time, the weather has become more springlike. This year we are on the weather seesaw with temps going up then back down. Currently, they are down. But that’s okay because it gives me the perfect opportunity to showcase this Irish adaptation of a French classic.

Rich & savory French onion soup starts with caramelized onions. A combination of beef broth and wine or sherry is added to the onions, and a toasted bread slice is topped with melted and bubbly Gruyere cheese and set on top of the crock of soup. Thyme and garlic add depth to the French version.

Irish onion soup also starts with caramelized onions. Potatoes, mushrooms, and rosemary add hearty earthiness to this soup. Stout beer and chicken broth make up the liquid base of the soup. The addition of sunflower seeds adds a bit of crunch to the texture of the soup. And here, toasted bread is topped with both goat cheese and cheddar cheese for the melty & bubbly effect. This Irish twist to classic French onion soup is perfect for St. Patrick’s Day!
