Preheat your oven to 400°F (200°C) and line your baking sheet with parchment paper.

Toss the cubed sweet potatoes in a mixing bowl with olive oil, garlic powder, salt, and pepper until well coated.

Spread the sweet potatoes on the prepared baking sheet in a single layer and roast for 25-30 minutes.

Cook the ground beef in a skillet over medium heat, stirring until browned for about 6-8 minutes.

Layer the bowls by starting with the roasted sweet potatoes, followed by the cooked ground beef, and top with cottage cheese.

Serve immediately and garnish with fresh herbs or seasonings if desired.
