🥄 How to Make Outback Walkabout Onion Soup
1. Sauté the Onions
In a large saucepan, melt the butter over medium heat. Add the thinly sliced onions and cook slowly, stirring occasionally, until the onions become soft, golden, and fragrant — about 10–12 minutes. The goal is to let them sweeten naturally without browning too much.
2. Build the Broth
Add the chicken broth, bouillon cubes, salt, pepper, and 1 cup of water. Stir well until the bouillon dissolves. Bring the mixture to a gentle simmer and allow it to cook for 10 minutes so the flavors deepen.
