Step 1

Heat the olive oil in an eight inch cast iron skillet over medium heat. Add the onions and reduce the heat to low. Allow the onions to caramelize slowly, stirring occasionally, every five to ten minutes. They are done when they are a deep golden brown.  About 45 minutes.

Step 2

Once the onions are caramelized to your desire (around 30 minutes) deglaze the pan with the white wine. Scrape up any stuck-on bits of caramelization and stir it into the onions.

Step 3

Turn off the heat and stir in the brie cheese until it is melted. Season with salt and pepper and sprinkle the fresh thyme on top. Serve the hot caramelized onion dip with your favorite breads, chips, fruits, and vegetables.
