Perfectly Caramelized Onions

Instructions

1. 1

   Heat the olive oil and butter in a large skillet over medium-low heat until melted and combined.

2. 2

   Add the sliced onions and salt. Stir to coat evenly.

3. 3

   Cook the onions slowly over low heat, stirring every few minutes, until they become soft, deeply golden, and caramelized. This usually takes 30–40 minutes.

4. 4

   During the last 5 minutes of cooking, drizzle the balsamic glaze or balsamic vinegar over the onions and stir well to coat.

5. 5

   Taste and adjust salt if needed.
