How to Make Caramelized Onion Dip

Caramelize Onions: Start by heating butter in a non-stick or cast iron skillet over medium heat. Thinly slice your yellow onions using a mandoline, then cook them on low heat for 30-40 minutes. Stir often until they turn golden brown, soft, and sticky, creating that sweet, rich flavor.
-
Deglaze Pan: As the onions cook, add a splash of Sauvignon Blanc or water to the skillet. Use a spatula to scrape up the delicious browned bits stuck to the pan. This adds extra flavor; adjust the moisture as needed during cooking.

Combine Ingredients: In a spacious bowl, mix the caramelized onions with sour cream, cream cheese, and minced garlic. Pour in the soy sauce and stir until everything is well blended. Taste and adjust seasonings if desired; the dip should be creamy and flavorful!
