Ingredients

2 large yellow onions

4 Tbsp. butter

1/4 cup vegetable oil

1/8 tsp. cayenne pepper

1 tsp. salt

1/2 tsp. pepper

4 oz. cream cheese, room temperature

1/2 cup sour cream

1/2 cup mayonnaise

Preparation

Cut onions in half and then slice them into 1/8-inch half rounds. Heat butter and oil in a large sauté pan on medium heat. Add the onions, cayenne, salt, and pepper and sauté for 10 minutes. Reduce the heat to medium-low and cook, stirring occasionally, for 20 minutes, until onions are browned and caramelized. Allow onions to cool.

Place cream cheese, sour cream, and mayonnaise in a food processor and beat until smooth. Add onions and mix well. Taste for seasoning. Serve at room temperature.
