**Cook the Bacon:** Heat a medium saucepan or skillet over medium heat. Add the chopped bacon and cook until crispy. Remove the bacon with a slotted spoon and set aside, leaving the bacon drippings in the pan.

**Sauté the Onion and Garlic:** Add the diced onion to the pan with the bacon drippings. Sauté for 3-4 minutes until softened. Add the minced garlic and cook for 1 more minute, stirring constantly.

**Add the Green Beans:** Stir in the drained green beans, chicken broth, and brown sugar. Mix well to combine.

**Simmer:** Reduce the heat to low and let the mixture simmer for 5-7 minutes, allowing the flavors to meld.

**Season and Serve:** Add salt and pepper to taste. Sprinkle the crispy bacon on top before serving.
