Cook bacon by your preferred method (frying, baking or microwaving) until bacon strips are cooked enough to chop into large pieces (they should be done, but not completely crisp).
Preheat oven to 350°.
Drain the green beans and place them in a 9×13″ baking pan.
Spread the chopped bacon on top of the green beans.
Combine the brown sugar, butter, soy sauce, and garlic powder in a small bowl.
Pour this mixture over the green beans and bacon.
Bake uncovered at 350 degrees for 40 minutes.
Remove from oven and serve.
