Step 1

Peel the onions and slice them very thinly. I find it helpful to use a mandoline for this.

Step 2

Heat the butter in a nonstick skillet over medium heat. Add the onions, sprinkle with salt and sugar, and saute for 10-15 minutes, stirring every few minutes. Pour a little bit of wine in and let it sizzle out. Stir, add wine, sizzle, etc. After about 30 minutes, your onions should be deeply golden brown and fragrant.

Step 3

Transfer onions to a cutting board and chop coarsely into small pieces – or just use a kitchen scissors and snip them up right in the pan. Mix the cream cheese and sour cream. Mix in the onions and a handful of fresh parsley. Taste and season – if you want just a little sumthin sumthin extra, add a small splash (like, a tablespoon or less) of soy sauce and/or Worcestershire. This just gives it a little depth and umami flavor.
