1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
2. In a large bowl, combine the cubed sweet potatoes with olive oil, minced garlic, salt, and pepper. Toss until the sweet potatoes are evenly coated.
3. Spread the sweet potatoes in a single layer on the prepared baking sheet. Ensure they are not overcrowded, as this will help them roast evenly.
4. Roast in the preheated oven for 25-30 minutes, or until the sweet potatoes are tender and golden brown on the edges. Stir halfway through for even cooking.
5. Once roasted, remove the sweet potatoes from the oven and sprinkle them with grated parmesan cheese and dried oregano, if using. Return to the oven for an additional 5 minutes until the cheese is melted and slightly crispy.
6. Remove from the oven and let them cool for a few minutes. Garnish with freshly chopped parsley before serving for a pop of color and freshness.

One of my favorite memories is watching my abuela cook with such ease and grace. She always said, “Cook with love, and it will show in your food” — a mantra I live by in my kitchen.
