Step-by-Step Instructions
First things first, let’s get those onions caramelizing! In a skillet over medium-low heat, melt a tablespoon of butter and add the thinly sliced onions. Stir them occasionally and let them cook down for about 20 minutes until they turn a lovely golden brown — this really brings out their natural sweetness. While they’re cooking, mix together the mayonnaise, ketchup, Dijon mustard, and Worcestershire sauce in a bowl to create my secret sauce. It’s so simple, but those flavors work wonders together!
