This caramelized onions recipe from Rach uses ingredients that highlight the natural sweetness of onions: butter, thyme, bay leaves and a splash of sherry.
She uses these in her Easiest Brisket Ever but they're also delish on her Bacon Burgers and Turkey Cheeseburgers, or try some of our favorite twists: Honey-Mustard Chicken Mac 'n Cheese with Caramelized Red Onions and Trisha Yearwood's Caramelized Onion Dip.
In a large cast iron skillet or large cast iron enamel Dutch oven over medium-low to medium heat, caramelize the onions: melt butter, add onions, season with bay, salt and black pepper and white pepper, thyme, cook to golden and soft, 25 minutes, then add sherry if using and remove to a bowl.
