332ml sour cream or crème fraîche (can swap up to half with mayo) (332mL = 12 oz)
225g cream cheese (225g = 8 oz)
1 tbsp fresh parsley, finely chopped
soy sauce or worcestershire sauce to taste
Instructions
Chop onions very small. Add butter to pan on medium heat. Once hot, add onions, salt and (optional) sugar. Cook until caramelized, about 15-30 mins. Don’t let them get overly crispy or browned.
Set aside to cool.
In medium bowl, combine the remaining ingredients. Add cooled onions.
Add soy sauce or worcestershire to taste (no more than a tablespoon).
Cover and refrigerate at least 1 hour, best if overnight.
Notes
Definitely best if left overnight for flavors to meld.
