Add the onions to the pan. Sauté until browned, about 8 minutes. Add the garlic and stir for 1 minute.
Add the beans, root beer, vinegar, sugar, tomato paste, mustard, chili powder, paprika, cinnamon, hot sauce, salt, and pepper. Stir to combine. Add the bacon and bring to a boil.
Transfer the pan to the oven. Bake, uncovered, until the liquid thickens, about 30 minutes. Serve topped with green onions for garnish.
