Trust me, the secret sauce is what makes this dish incredible.

Preheat your oven to 400°F (200°C).

In a large bowl, combine the sweet potatoes, olive oil, minced garlic, dried thyme, dried rosemary, salt, and pepper. Toss until the sweet potato cubes are evenly coated.

Spread the sweet potatoes in a single layer on a baking sheet lined with parchment paper.

Roast in the preheated oven for 25-30 minutes, stirring halfway through, until the sweet potatoes are golden brown and tender.

Remove from the oven and immediately sprinkle the grated parmesan cheese over the hot sweet potatoes. Toss lightly to ensure the cheese melts and coats the potatoes evenly.

Transfer to a serving dish and garnish with fresh chopped parsley, if using. Serve hot.

For a spicier kick, add a pinch of red pepper flakes to the seasoning mix. You can also switch out the parmesan for pecorino or a similar hard cheese for a different flavor profile. If you prefer a vegan version, nutritional yeast can be used in place of parmesan to maintain that cheesy flavor. Additionally, try using a mix of sweet potatoes and regular potatoes for a variety in taste and texture.
