Preheat your oven to 400°F (200°C).

Peel and cube the sweet potatoes, then toss in a bowl with olive oil, garlic powder, salt, and pepper. Spread on a baking sheet and roast for 20-25 minutes.

Steam or blanch broccoli florets for 3-4 minutes until bright green and crisp-tender. Drain and set aside.

In a skillet over medium heat, cook bacon strips until crispy (5-7 minutes). Drain and crumble.

In a greased 9x13-inch baking dish, layer roasted sweet potatoes, broccoli, and crumbled bacon. Sprinkle cheese and mix to combine.

Sprinkle remaining cheese on top and bake uncovered for 15-20 minutes until melted and bubbly.

Garnish with chopped parsley or chives, let cool slightly, and serve warm.
