  1. Cook the bacon: In a large cast iron skillet over medium heat, cook bacon until crispy. Transfer bacon to a paper towel–lined plate and reserve the drippings in the skillet.
  2. Caramelize the onions: Add the sliced onions to the bacon drippings. Reduce heat to medium-low and cook, stirring regularly, until the onions are deep golden brown and sweet.
  3. Combine the dip: Remove the skillet from the heat. Add cream cheese, sour cream, mayonnaise, shredded gouda, shredded cheddar, granulated garlic, dried thyme, salt, and pepper. Stir until the cheeses melt and the mixture is smooth. Crumble the cooked bacon and sprinkle most of it on top, reserving a little for garnish.
