In a large pot, heat butter and olive oil over medium heat.
Add the onions, salt, and pepper, and cook until they are caramelized, about 25–30 minutes.
Pour in the non-alcoholic stout alternative (or extra beef broth with balsamic), then add the beef broth; bring to a simmer for 10–15 minutes.
Preheat the oven to broil.
Place baguette slices on a baking sheet and toast until golden brown.
Ladle the soup into oven-safe bowls, top with baguette slices, and sprinkle with shredded cheddar cheese.
Place the bowls under the broiler for a few minutes until the cheese is melted and bubbly.
Serve warm and enjoy!
