Ingredients
Method
Onions
- Preheat the oven to 350°F. Grease a 9×13-inch baking dish and arrange the onion halves cut-side up in a single layer.
Sauce
- In a medium bowl, whisk together melted butter, apple cider vinegar, brown sugar, Worcestershire sauce, salt, and pepper until smooth and glossy.
Bake
- Pour the sauce evenly over the onions, cover tightly with foil, and bake for 1 hour.
- Remove the foil and bake for an additional 15 minutes until the edges are golden and slightly crisp.
Notes
Cool completely and store in an airtight container in the refrigerator for up to 4 days.
To make ahead, assemble and refrigerate covered up to 8 hours before baking, then bring to room temperature before cooking.
Always refrigerate within 2 hours of cooking to meet food safety guidelines.
