The dip is best made at least 4 hours in advance and can easily be made the day before.
Makes about 3 cups
Ingredients:
- 2 tablespoons salted butter
- 1 pound sweet onions, such as Vidalia or Peruvian, cut into 1/4- to 1/2-inch dice
- 1/2 cup finely chopped scallions, white and tender green parts
- 1/4 cup finely chopped chives
- 1 cup sour cream
- 8 ounces cream cheese, at room temperature
- 1/2 teaspoon salt (optional)
Directions:
In a large skillet over medium heat, melt the butter. Add the onions, reduce the heat to medium-low and cook for 10 to 12 minutes, stirring occasionally, until the onions just begin to turn golden. Add the scallions and cook for 3 to 4 minutes, stirring. Remove from the heat; add the chives and mix well. Transfer the onion mixture to a bowl and set aside to cool slightly.
While the onion mixture is cooling, combine the sour cream, cream cheese and salt in a medium bowl. (These can be mixed by hand if the cream cheese is soft or in a food processor if the cream cheese is still firm.) Add the onion mixture and stir to combine. Taste and add salt, if desired. Cover and refrigerate until ready to serve.
