Ingredients
For the Sweet Potatoes:
- 3 medium sweet potatoes, peeled and cut into wedges or cubes
- 2 tablespoons olive oil
- 2 teaspoons fresh rosemary, finely chopped (or 1 tsp dried rosemary)
- ½ teaspoon garlic powder
- ¼ teaspoon onion powder
- Salt and black pepper to taste
- ⅓ cup grated Parmesan cheese (plus extra for serving)
- Optional: pinch of chili flakes for a spicy kick
- Optional: fresh parsley for garnish
Step-by-Step Instructions
1. Prepare the potatoes
- Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper.
- Peel and cut sweet potatoes into uniform wedges or cubes to ensure even cooking.
2. Season the potatoes
- In a large bowl, toss sweet potatoes with olive oil, rosemary, garlic powder, onion powder, salt, and pepper.
- Sprinkle in half of the Parmesan cheese and toss again to coat evenly.
3. Arrange on baking sheet
- Spread potatoes out in a single layer on the prepared baking sheet.
- Ensure they are not overlapping—crowding can cause steaming instead of roasting.
4. Roast until crispy
- Roast in the oven for 30–35 minutes, flipping halfway through for even browning.
- For extra crispiness, broil for the last 2–3 minutes, watching carefully to avoid burning.
5. Add final toppings

Ingredient Background
Sweet potatoes
- Rich in fiber, antioxidants, and vitamins like A and C, sweet potatoes offer both nutrition and natural sweetness.
- Their starchy texture becomes perfectly crisp when roasted and complements savory toppings well.
Rosemary
- A fragrant herb that pairs beautifully with roasted vegetables, adding a piney, earthy aroma and flavor.
- Fresh rosemary gives better texture and color, while dried works well in a pinch.
Parmesan cheese
- A hard, aged cheese with a sharp, nutty flavor that melts slightly while baking, creating a crispy, golden coating.
- Adds umami depth and enhances the savory profile of the dish.
Olive oil and spices
- Olive oil helps crisp the edges and allows the seasoning to coat evenly.
- Garlic powder and onion powder build an aromatic base without overpowering the natural flavors.
Technique Tips
- Cut sweet potatoes into even pieces for uniform cooking.
- Preheat the oven fully before roasting to ensure a crispy finish.
- Avoid overcrowding the pan—roast in batches if needed for optimal caramelization.
- Toss potatoes in the seasoning thoroughly to ensure every piece is well-coated.
- Broil briefly at the end for extra golden edges, but don’t walk away—it can go from crisp to burnt quickly.
- Use freshly grated Parmesan for better melting and stronger flavor compared to pre-shredded.
Alternative Presentation Ideas
- Serve in a rustic bowl or platter lined with parchment paper for a farmhouse feel.
- Stack potato wedges in a vertical arrangement and sprinkle with rosemary sprigs.
- Garnish with shaved Parmesan and lemon zest for a gourmet touch.
- Add a drizzle of balsamic glaze or garlic aioli on the side.
- Present in mini serving bowls for individual portions at dinner parties.
Additional Tips for Success
- Use parchment or a silicone mat to prevent sticking and encourage even browning.
- Stir halfway through roasting to avoid uneven cooking and sticking.
- Sprinkle extra Parmesan during the last 5 minutes of baking for a crisp, cheesy crust.
- Add a small amount of crushed nuts like pecans or walnuts for texture variation.
- Make it spicier with cayenne pepper or smoked paprika.
- Use a mix of orange and purple sweet potatoes for visual appeal.
Recipe Variations
- Garlic Herb Sweet Potatoes: Add minced garlic and fresh thyme instead of rosemary.
- Spicy Parmesan Wedges: Toss with chili flakes and smoked paprika for a bold kick.
- Sweet and Savory Mix: Add a drizzle of maple syrup with rosemary and cheese for sweet-savory contrast.
- Lemon Rosemary Potatoes: Add lemon zest and a squeeze of juice before serving for a citrus twist.
- Parmesan Herb Fries: Cut potatoes into fries instead of wedges for a fun variation.
- Crispy Roasted Coins: Slice into thin coins and roast extra crisp with cheese on top.
Freezing and Storage
Storing
- Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheat in the oven at 375°F (190°C) for 8–10 minutes to revive crispness.
Freezing
- It’s best to freeze prepped but uncooked sweet potato wedges.
- Spread on a tray, freeze individually, then transfer to freezer bags.
- Roast from frozen, adding 5–7 minutes to cooking time.
Healthier Twist Ideas
- Use less cheese and more herbs to lighten the calorie count.
- Opt for avocado oil for a heart-healthy alternative to olive oil.
- Add chopped kale or spinach at the end for added nutrients.
- Reduce salt and add lemon zest or fresh garlic for flavor enhancement.

- Use low-fat Parmesan alternatives if desired.

Frequently Asked Questions
1. Can I use other types of potatoes?
- Yes, but the flavor will differ. Sweet potatoes offer natural sweetness that pairs best with rosemary and Parmesan. Yukon Gold or red potatoes can also be used.
2. Do I have to peel the sweet potatoes?
- Peeling is optional. The skin becomes crisp when roasted and is rich in nutrients. For a rustic touch, leave the skin on.
3. Can I use dried rosemary instead of fresh?
- Yes. Use about half the amount of dried rosemary, as it’s more concentrated in flavor.
4. Can I make these in an air fryer?
- Absolutely. Cook at 375°F (190°C) for 12–15 minutes, shaking halfway through. Reduce the amount of oil slightly.
5. How do I keep the potatoes from getting soggy?
- Don’t overcrowd the baking sheet, and ensure the oven is fully preheated. Use high heat to promote browning and crispness.
6. What kind of cheese works best besides Parmesan?
- Grated Romano, Asiago, or a dairy-free cheese alternative can be used. Hard cheeses work best for crisp coating.
7. Can I prepare this dish ahead of time?
- Yes, prep the sweet potatoes and season them in advance. Roast just before serving for best results.
8. How do I reheat them without losing crispiness?
- Reheat in a hot oven or air fryer instead of the microwave. This helps restore the roasted texture.
