Instructions
-
Caramelize: Melt butter and oil in a large skillet over medium heat. Add the diced onions, salt, and sugar. Cook, stirring occasionally, until the onions reach a deep, mahogany brown. If the pan gets too dry, deglaze with a splash of water or beef broth.
-
Cool: Transfer the onions to a bowl and let them reach room temperature. Adding hot onions to the dairy base will make the dip runny.
-
Mix: In a separate bowl, whisk together the sour cream, mayonnaise, and seasonings. Fold in the cooled onions.
-
Meld: Cover and refrigerate for at least 2 hours, or overnight. This rest period is essential, allowing the onion flavor to permeate the creamy base.
-
Serve: Give it a final stir and serve with high-quality, ridged potato chips for the perfect crunch.
Pro-Tips for a Bistro-Style Result
-
Deglazing: For a sophisticated, bistro-style tang, deglaze the pan with a splash of dry white wine or cognac once the onions are browned.
-
Texture Control: If you prefer a smoother, more refined dip, you can briefly pulse the finished mixture in a food processor.
-
The Make-Ahead Advantage: This dip actually tastes better the next day and will hold perfectly in the refrigerator for up to 5 days, making it the ultimate stress-free party hack.
A Note on Dippers: While a thick, rippled potato chip is the gold standard, this dip is versatile. It holds up beautifully on toasted baguette slices, crisp apple wedges, or as a decadent topping for a loaded baked potato.
