What Kind of Sweet Potatoes Work Best?

For this recipe, orange-fleshed sweet potatoes (like Garnet or Jewel varieties) are ideal. They have a naturally creamy texture and a hint of caramel-like sweetness that pairs beautifully with the garlic and parmesan. Choose medium-sized potatoes that feel firm and smooth, with no soft spots or wrinkles.

Cutting them into evenly sized chunks ensures they roast uniformly, giving you that deliciously crisp exterior while keeping the insides melt-in-your-mouth soft.

How To Make the Garlic Parmesan Sweet Potato

Step 1: Prep and Preheat

Start by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it to prevent sticking. This ensures easy cleanup and even roasting.

Step 2: Cube the Sweet Potatoes

Peel the sweet potatoes and cut them into 1 to 1.5-inch cubes. Try to keep the pieces uniform in size so they cook evenly. Place them in a large mixing bowl.

Step 3: Season Generously

To the bowl, add melted butter (or olive oil), minced fresh garlic, salt, pepper, and optional garlic powder and paprika. Toss the cubes thoroughly until each one is coated with the flavorful mixture.

Step 4: Roast to Perfection

Spread the seasoned sweet potato cubes out in a single layer on your prepared baking sheet. Bake for 30–35 minutes, flipping halfway through, until the edges are crispy and golden brown, and the centers are soft.

Step 5: Add the Parmesan & Herbs

Once the potatoes are out of the oven, sprinkle generously with grated parmesan cheese while they’re still hot so it melts slightly and sticks. Add a handful of freshly chopped parsley for that fresh, herby finish.

Step 6: Serve and Savor

Transfer to a serving plate, drizzle with any leftover garlic butter from the pan, and enjoy immediately while warm and crispy. These are especially good straight from the oven!

Serving and Storing Garlic Parmesan Sweet Potato

These garlic parmesan sweet potatoes are best served hot from the oven, when the edges are crisp and the cheese is melty. They’re a perfect side for roasted chicken, steak, or even a fresh salad. You can also serve them as an appetizer with a creamy dipping sauce like garlic aioli or sour cream and chive dip.

To store leftovers, let the potatoes cool completely and place them in an airtight container in the fridge. They’ll stay fresh for up to 4 days. Reheat in the oven or air fryer at 375°F for about 10 minutes to revive that crisp texture. Microwaving works too, but they’ll be softer.

Frequently Asked Questions

How do I keep the sweet potatoes crispy?

Make sure the potatoes are spread out in a single layer on the baking sheet without overcrowding. This allows them to roast instead of steam. Using parchment paper and flipping them halfway through baking also helps with even browning.

Can I make this recipe vegan?

Absolutely! Swap out the butter for olive oil or a vegan butter alternative, and use a dairy-free parmesan-style cheese or nutritional yeast for that savory finish.

Do I have to peel the sweet potatoes?

Peeling is optional. If you love that rustic texture, give them a good scrub and leave the skin on. It adds a nice bite and extra fiber.

Can I air fry instead of oven roast?

Yes! Preheat your air fryer to 375°F and cook the seasoned sweet potato cubes in batches for about 15–18 minutes, shaking halfway through. Add the parmesan and herbs after air frying.

What other herbs can I use besides parsley?

Fresh thyme, rosemary, or even a sprinkle of chives can add delicious variations. Mix and match based on what you’re serving these with.

Are these good for meal prep?

Definitely. They reheat well in the oven or air fryer, making them a great make-ahead option for lunch bowls, dinner sides, or snack boxes.
