Heat olive oil in a large sauté pan over low heat. Add sliced onions and minced garlic, stirring occasionally. Cook for 15 to 20 minutes until softened and golden brown.

Remove the pan from heat and allow the mixture to cool for about 5 to 10 minutes.

Finely chop the cooled onion and garlic mixture and transfer it to a mixing bowl. Add Greek yogurt, Worcestershire sauce, salt, black pepper, dried parsley, and garlic powder. Stir until well combined.

Serve the dip in a stylish bowl with veggie sticks, whole-grain crackers, or pita chips.
