Preheat your oven to 400°F (200°C).

Peel the sweet potatoes and chop into 1-inch cubes.

In a large mixing bowl, whisk together olive oil, honey, ground cinnamon, salt, and optional black pepper.

Add the sweet potatoes to the bowl and gently toss until coated.

Spread the coated sweet potato cubes in a single layer on a baking sheet lined with parchment paper.

Roast in the oven for 25–30 minutes, flipping halfway through for even browning.

Let the sweet potatoes rest for 5 minutes after roasting.

Garnish with chopped parsley before serving.
