Let’s break down exactly why this recipe works so well — and how to make the perfect batch every time.

Sweet potatoes often get the reputation of being sweet-only, but roasting them with garlic, parmesan, and herbs unlocks a deeper, richer flavor profile that is both earthy and comforting.
⭐ Ingredients You’ll Need
Sweet Potatoes
Cut into even cubes to promote perfect roasting.
Olive Oil
Helps crisp up the potatoes while carrying flavor.
Garlic
Fresh minced garlic roasts into the potatoes, infusing them with savory richness.
Parmesan Cheese
Adds nutty, salty flavor and helps crisp the edges.
Herbs
Parsley adds brightness; dried Italian seasoning elevates everything.
Salt & Pepper
Essential for balancing the natural sweetness of the potatoes.
⭐ How to Make Garlic Parmesan Roasted Sweet Potatoes
1. Preheat the Oven
Roasting requires high heat. Preheat to 425°F (220°C) for maximum crispiness.
2. Prep the Sweet Potatoes
Peel if you want, though leaving the skin adds texture and nutrients. Dice into evenly sized cubes (about 1 inch).
3. Season
Toss sweet potatoes with olive oil, garlic, salt, pepper, Italian seasoning, and half of the parmesan.
4. Spread on a Baking Sheet
Place in a single layer for even browning. Crowding = steaming, not roasting.
5. Roast
Bake for 28–35 minutes, flipping halfway until golden and crisp on the edges.
6. Add More Parmesan
As soon as they come out of the oven, sprinkle the remaining parmesan so it melts slightly.
7. Serve and Enjoy
Top with parsley and serve warm.
