Place sour cream in a small bowl. Add dried onion, onion powder, garlic powder, salt, and parsley. Mix together very well until completely uniform. Taste with a chip and adjust seasonings if necessary.
Refrigerate for 1 hour to allow the flavors to meld and the dried onion to soften. Store in the refrigerator for 5 to 7 days.
Notes
This dip is great for parties and can be served with chips or vegetables.
