This flavorful onion and ale soup is a cozy, cold-weather classic—loaded with sweet onions and finished with a splash of Irish stout for depth.
Some evenings you don’t feel like cooking, you don’t want fast food, and a diner just won’t do. For nights like that we often head to the neighborhood pub: warm, familiar, and full of good food. I’m guilty of always ordering the same thing, but on one visit the menu listed Onion and Ale Soup and the description caught my eye. It sounded easy to recreate at home, so I tried it—and it turned out delicious.
This soup is similar to French onion but the stout gives it a robust, slightly bitter-sweet twist. I also used a beer-flavored vinegar to deepen the beer notes, which worked beautifully. If you enjoy the combination of caramelized onions and beer, this soup is for you.

Ingredients
- 2 tablespoons extra virgin olive oil

- 3 medium red onions, thinly sliced
- 2 teaspoons kosher salt
- 1/4 teaspoon black pepper
- 1 16-ounce can Irish stout beer

Instructions
- Heat the olive oil in a large skillet over medium heat.

- Add all the sliced onions, season with kosher salt and black pepper, and cook for about 5 minutes to begin softening.
- Reduce the heat to low and cook the onions gently for about 30 minutes. For a sweeter onion flavor, cook longer on low heat—do not brown the onions.
- Pour in the stout and simmer for 5 minutes to meld flavors.
- Add the thyme and sherry vinegar, then simmer gently for 10–15 minutes until the mixture reduces by about half.
- Stir in the beef stock and simmer until the soup is heated through and flavors combine, approximately 10 minutes.
- Preheat the broiler.
- Ladle the soup into ovenproof bowls, top with shredded Irish cheddar, and broil until the cheese melts and begins to brown. Serve hot.
This onion and ale soup makes a comforting starter or a satisfying main when paired with crusty bread. The slow-cooked onions bring natural sweetness while the stout and vinegar add complexity—resulting in a rich, well-balanced soup perfect for chilly nights.
