Step 1: Sauté Onions and Garlic. Heat a sauté pan over low heat and add olive oil, allowing it to warm for about 1 minute. Carefully add the sliced onions and minced garlic, stirring occasionally. Cook for 15-20 minutes until golden brown.

Step 2: Cool the Mixture. Once the onions are caramelized, remove from heat and cool for 5-10 minutes.

Step 3: Combine Ingredients. Transfer the cooled onions to a mixing bowl. Add Greek yogurt, Worcestershire sauce, salt, black pepper, dried parsley, and garlic powder. Mix until well combined.

Step 4: Chill Before Serving. Cover and refrigerate for at least 30 minutes to let flavors meld.

Step 5: Serve and Enjoy. Serve the dip cool with vegetable sticks, whole-grain crackers, or potato chips.
