Irish Onion Soup is a twist on the traditional French Onion Soup that has a deep, rich flavor that will leave you wanting more!   Back in the day, I served this soup at my little cafe. The lunch hour started at 11:00, and by noon, this soup would be gone!

CookingWithLisaB - Irish Onion Soup


1 bottle Guinness beer
4 large white onions, sliced
3 tbsp butter
2 32 ounce containers beef stock
2 tsp salt and pepper each
French baguette, sliced thick
salted butter softened
Baby Swiss cheese slices
Fresh Thyme, for garnish


  1. In a large pot, saute the onions, salt, pepper, and 3 tbsps butter till the onions are lightly browned.
  2. Meanwhile, in a small pot, reduce the beer over medium-high heat.  This should reduce by half and resemble a light syrup.
  3. Gently stir the beer mixture into the onions. Heat until boiling.
  4. Add the beef stock and bring to a simmer.
  5. While the soup is heating, spread a light coating of butter on the baguette slices and top with the Baby Swiss cheese.
  6. Broil the bread just a few minutes, until the cheese is lightly browned.
  7. Ladle the soup into soup bowls or mugs (be sure to scoop up those onions!).
  8. Top with a baguette slice or two and a sprinkle of Thyme leaves.
  9. Serve the Irish Onion Soup piping hot!

You can also serve a simple salad of lettuce, tomatoes, blue cheese crumbles and a drizzle of olive oil.
