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