How to make this recipe
In a large saucepan, melt the butter in the oil. Add the onions and cook over high heat, stirring frequently, until just softened and beginning to brown, about 10 minutes. Reduce the heat to moderate and cook, stirring frequently, until the onions are golden and softened, about 20 minutes. Add the garlic and cook until fragrant, about 1 minute. Let cool, then coarsely chop the onions.
In a standing mixer fitted with the paddle, beat the cream cheese at medium speed until smooth. Beat in the mayonnaise and sour cream. Fold in the onions and season generously with salt and pepper. Scrape into a bowl, cover and refrigerate until chilled. Sprinkle with the parsley and serve with potato chips.
