Drizzle the olive oil in a pan over medium heat. Then, add the onions.

Cook until onions are caramelized.

Add the yogurt, sour cream, butter, garlic, parsley, salt, and pepper to the pan.

Use a wooden spoon to stir well until the mixture is well combined.

Transfer to a bowl, and let cool for at least five minutes.

Serve with bread, toasted baguettes, crackers, chips, or veggies, and enjoy.
