Ingredients
Scale
- 4 tablespoons unsalted butter
- 2 tablespoons olive oil
- 4 cups yellow onions, sliced
- 5 cups beef broth
- 2 tablespoons dry sherry

Instructions
- Heat a Dutch oven or large pot over medium heat. Add butter and olive oil, stirring until the butter melts.

Notes
Make sure to slice your onions evenly and don’t rush the caramelization process for the best flavor. Store leftovers in an airtight container in the fridge for up to 3 days.
