- 3 pound(s) uncooked onion(s), sliced (about 6 to 7 large onions)
- 2 Tbsp unsalted butter, melted
- 2 tsp kosher salt
- 1/4 cup(s) fino sherry
- 2 tsp minced garlic

Instructions
- Combine onions, butter and salt in a slow cooker; cover and cook on high until onions are well-browned, about 8 to 10 hours. Add sherry and garlic; stir to combine. Leave slow cooker set to high and let sit, uncovered, for alcohol to burn off, about 10 to 15 minutes.
