Preheat your oven to 375°F (190°C) and grease a 9×13 baking dish with butter or non-stick spray.

Spread the trimmed fresh green beans evenly in the greased baking dish in a single layer.

In a skillet, cook thick-cut bacon over medium heat until crispy, about 8-10 minutes. Drain excess grease and chop into bite-sized pieces.

Melt butter in a saucepan over medium-low heat, then stir in brown sugar, soy sauce, garlic powder, and black pepper. Simmer for 3-4 minutes until glossy and thickened.

Pour the brown sugar glaze over the green beans and sprinkle the chopped bacon on top.

Bake uncovered for 30-35 minutes, stirring halfway through for even cooking.

Let the dish rest for about 5 minutes before serving to enhance flavors.
