Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish.

If using canned beans, drain thoroughly. If fresh, blanch in salted water for 3-4 minutes, then transfer to an ice bath.

In a skillet, cook chopped bacon over medium heat until crispy, about 5-7 minutes. Drain on paper towels, reserving 2 tablespoons of grease.

In the same skillet, melt butter, then stir in brown sugar, soy sauce, and garlic powder, mixing until smooth and thick, about 2-3 minutes.

Layer green beans in the greased dish, pour the glaze over them, and sprinkle with crumbled bacon.

Bake uncovered for 30-40 minutes until bubbly and caramelized.

Let cool slightly before serving warm.
