Ingredients You’ll Need
- 4 large onions, thinly sliced
- 4 tablespoons unsalted butter
- 1 teaspoon sugar (for caramelizing)
- 3 cups beef broth

- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 cup Gruyère cheese, shredded (or Swiss, mozzarella, or provolone)
- Crusty bread slices, for topping
How to Make Walkabout Onion Soup
1. Caramelize the Onions:
In a large pot, melt butter over medium heat. Add the sliced onions and cook, stirring often, for about 10 minutes. Sprinkle in the sugar and continue cooking for another 10 minutes until golden and tender.
2. Simmer the Broth:
Stir in the beef broth, soy sauce, Worcestershire sauce, salt, and pepper. Bring to a boil, then reduce heat and let simmer for 20 minutes to deepen the flavor.
3. Broil the Topping:
Preheat your oven broiler. Ladle soup into oven-safe bowls, place a slice of crusty bread on top, and generously sprinkle with cheese.
4. Melt the Cheese:
Place bowls on a baking sheet and broil for 2–3 minutes, just until the cheese is melted and golden brown. Watch carefully so it doesn’t burn.
5. Serve and Enjoy:
Carefully remove bowls from the oven, let cool slightly, and enjoy with extra bread or a fresh salad on the side.
Serving Suggestions
- Pair with a green salad or bruschetta for a lighter meal.
- Add a grilled cheese sandwich on the side for ultimate comfort.
- A glass of red wine like Merlot or Shiraz pairs beautifully with the rich flavors.
Pro Tips for the Best Onion Soup
- Use a mix of yellow and sweet onions for the best depth of flavor.
- Gruyère is classic, but you can use mozzarella, provolone, or Swiss for variety.
- Caramelizing onions takes time—low and slow is the key to golden perfection.
- Store leftovers in an airtight container for up to 4 days in the fridge.
Storage and Reheating
Let the soup cool completely before storing. Keep it in the fridge for 3–4 days, or freeze for up to 2 months in labeled freezer-safe containers. Reheat on the stovetop over medium heat or in the microwave until hot.
If freezing, wait to add the bread and cheese topping until ready to serve.
