2 large sweet yellow onions such as Vidalia or Walla Walla cut in half lengthwise and sliced thinly
2 tablespoons butter
1 tablespoon olive oil
2 ounces whipped room temperature cream cheese
1/3 cup sour cream
1/3 cup mayonnaise
pinch of cayenne pepper
salt and freshly cracked black pepper to taste
METHOD
Place a large heavy bottomed skillet over medium-high heat.
Add butter and olive oil.
When butter and olive oil are hot add the onions along with a pinch of salt and stir to coat them in the hot fat.
Continue to stir the onions frequently until they have given off a good amount of moisture and begin to turn a pale yellow - about 10 minutes.
Turn the heat down to medium-low and stir the onion every five minutes or so until richly browned and caramelized all over - about another 30-40 minutes.
Remove the pan from heat and allow the onions to cool before combining them with the remaining ingredients in a food processor fitted with a metal blade or in a stand mixer with a paddle attachment.
Makes about 2 cups
