   In a large skillet, melt the butter with olive oil over medium-low heat. Add the sliced onions and cook slowly, stirring occasionally, until deeply caramelized and browned, about 25-30 minutes. Do not rush this process, as it develops the flavor.

   Add the minced garlic and red pepper flakes to the skillet and cook for 1 minute more until fragrant.

   Stir in the Worcestershire sauce, balsamic vinegar, and beef broth. Bring to a simmer and cook until the liquid has mostly evaporated, about 5-7 minutes. Season with salt and black pepper.

   While the onions are finishing, slice the baguette into 1-inch thick rounds. Place them on a baking sheet and toast lightly under the broiler or in a toaster oven until golden brown.
