There are not words to describe how good this is. It's out of control addicting and WAY better than the mix or pre-made onion dip. Men love it, woman too...you really can't go wrong. Serve with crinkle potato chips or fresh veggies for an irresistable appetizer!
2 large yellow onions
4 tablespoons unsalted butter
1/4 cup vegetable oil
1/4 teaspoon ground cayenne pepper
1 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
4 ounces cream cheese, room temperature
1/2 cup sour cream
1/2 cup good mayonnaise
Cut the onions in half, and then slice them into 1/8-inch thick half-rounds. (You will have about 3 cups of onions) Heat the butter and oil in a large sauté pan on medium heat. Add the onions, cayenne, salt and pepper and sauté for 10 minutes. Reduce heat to medium-low and cook, stirring occasionally, for 20 more minutes, until the onions are browned and caramelized. Allow the onions to cool.
Place the cream cheese, sour cream, and mayonnaise in the bowl of an electric mixer fitted with a paddle attachment and beat until smooth. Add the onions and mix well.
Taste for seasonings. Serve at room temperature.
