Creating Cinnamon Roasted Sweet Potatoes and Apples is a straightforward process. Follow these simple steps for a delicious outcome:

1. Preheat the Oven: Preheat your oven to 425°F (220°C).
2. Prepare the Sweet Potatoes: Peel and cube the sweet potatoes into uniform pieces for even cooking.
3. Prepare the Apples: Core and dice the apples into similar-sized pieces as the sweet potatoes.
4. Mix Ingredients: In a large bowl, combine the sweet potatoes, apples, olive oil, brown sugar, cinnamon, nutmeg (if using), salt, and black pepper. Toss everything together until well coated.
5. Spread on Baking Sheet: Line a large baking sheet with parchment paper for easy cleanup. Spread the mixture evenly on the baking sheet, ensuring the sweet potatoes and apples are in a single layer.
6. Roast in the Oven: Place the baking sheet in the preheated oven and roast for 30-35 minutes. Stir halfway through to ensure even cooking.
7. Check for Doneness: The sweet potatoes should be tender and slightly caramelized. You can check by piercing them with a fork; they should be soft but not mushy.
8. Garnish: Once done, remove from the oven and let cool for a couple of minutes. If desired, sprinkle fresh rosemary or thyme on top for added flavor.
9. Serve Warm: Transfer to a serving dish and enjoy warm.
