Preheat your oven to 400 degrees F and lightly spray a baking sheet with olive oil or your preferred non-stick cooking spray.
Rinse, peel, and dice your sweet potatoes into 1-inch cubes, then place them in a large bowl.
4 medium-large sweet potatoes
Add the olive oil, maple syrup, cinnamon, salt, and pepper, and toss to coat evenly.
¼ cup olive oil, ¼ cup maple syrup, 1 teaspoon ground cinnamon, ¼ teaspoon salt, ⅛ teaspoon black pepper
Spread the sweet potatoes onto the baking sheet in a single layer.
Roast for 25-30 minutes, flipping the sweet potatoes with a spatula halfway through.
Remove from the oven, then serve and enjoy!
