    Preparation Steps

    1

    Slice the onions thinly.

    2

    In a medium saucepan, melt the butter over medium heat, then add the onions.

    3

    Sauté the onions for 10-15 minutes, until softened and caramelized, stirring occasionally.

    4

    Sprinkle the brown sugar over the onions and sauté for another 2-3 minutes, allowing the onions to develop a deep, sweet flavor.

    5

    Pour in the red wine and bring to a simmer. Let it simmer for about 5 minutes to allow the alcohol to evaporate.

    6

    Add the broth, balsamic vinegar, fresh thyme, salt, and pepper.

    7

    Simmer over medium heat for 15-20 minutes, allowing the sauce to thicken and the flavors to meld.

    8

    If you prefer a thicker sauce, whisk the cornstarch with cold water and add it to the sauce. Cook for another 2-3 minutes, until it reaches the desired consistency.

    9

    Before serving, strain the sauce for a smoother texture, if desired. Serve warm with roasted meats or vegetables.
