Place the chopped bacon in a large skillet over medium-high heat.
Cook until the bacon is crispy.
Remove the bacon from the skillet and drain it on paper towels.
Add the chopped onion and minced garlic to the bacon grease in the skillet.
Sauté until the onions are translucent.
Add the trimmed green beans to the skillet.
Pour in the chicken broth and add the butter.
Season with sugar, salt, and black pepper.
Stir well to combine all the ingredients.
Bring the mixture to a simmer.
Then lower the heat to medium-low.
Cover the skillet and let it simmer for about 10 minutes, until the green beans are tender.
Uncover the skillet, stir in the cooked bacon, and let it heat through.
Serve the green beans warm.
