Classic Beef Burger with Caramelized Onions

Method

1. Heat a skillet over medium heat and add olive oil. Cook the ground beef until browned and cooked through, breaking into small pieces. Season with salt and pepper.
2. In the same skillet, add the onion slices and cook over low heat, stirring occasionally, until softened and caramelized (about 20 minutes).
3. Cook the bacon in a separate skillet until crispy. Set aside.
4. Toast the brioche bun in a toaster or on a skillet. Assemble the burger with the beef patty, caramelized onions, bacon, and cheddar cheese. Serve immediately.
5. Check that the ground meat reaches 71°C (160°F) throughout before serving.
