When working with a skillet full of raw sweet onions, volume management presents an immediate hurdle. Two large chopped alliums will mound high in standard pans, yet they reduce drastically as water evaporates and cellular walls break down. Proper caramelization requires patience, relying on a 35 to 40 minute cooking window to build deep umami without scorching the sugars.
Thorough chilling solidifies the fats in the cream cheese and thickens the Greek yogurt. Prepare the mixture several hours ahead to let the flavors meld fully.
