Ingredients List for the Crispy Roasted Sweet Potatoes:

These ingredients work together perfectly—the cornstarch helps create that irresistible crispy exterior while the spice blend enhances the sweet potatoes’ natural flavor without overwhelming it.

• 4 cups peeled & cubed sweet potatoes, 1/2-inch cubes
• 3 tablespoons olive oil
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/2 teaspoon smoked paprika
• 1/4 teaspoon garlic powder
• 1/4 teaspoon onion powder
• 1 1/2 teaspoons cornstarch

Pro Tips

For truly exceptional Crispy Roasted Sweet Potatoes, these three techniques make all the difference:

First, cut your sweet potatoes into consistent 1/2-inch cubes. Uniform size ensures even cooking—too small and they’ll burn, too large and they’ll be crispy outside but undercooked inside. A sharp knife and a little patience here pays huge dividends in the final result.

Second, don’t skip the cornstarch! This seemingly minor ingredient is what transforms good roasted sweet potatoes into exceptionally crispy ones. The cornstarch creates a thin coating that dehydrates and crisps beautifully in the oven. Make sure to mix it thoroughly with the spices before adding to ensure even distribution.

Finally, give those potatoes space on the baking sheet. Overcrowding is the enemy of crispiness. When sweet potatoes are too close together, they steam rather than roast, resulting in a softer texture. Use two baking sheets if necessary and rotate them halfway through cooking for optimal results. This single step can transform your roasted sweet potato experience from good to extraordinary.

Instructions

Step 1: Preheat oven (or an air fryer) to 425°F.

Step 2: In a small bowl, combine the salt, pepper, paprika, garlic, onion powder, and cornstarch; set aside.

Step 3: Add the cubed sweet potatoes to a large bowl and drizzle with olive oil and the seasoning.

Step 4: Stir until the sweet potatoes are evenly coated.

Step 5: Spread the sweet potatoes onto a large cookie sheet.

Step 6: Bake for 15 minutes then flip them over with a spatula. Bake an additional 5–10 minutes or until the sweet potatoes are soft on the inside and golden and crisp on the exterior.

Variations

Take your Crispy Roasted Sweet Potatoes in exciting new directions with these delicious variations:

Maple Cinnamon Sweet Potatoes: For a sweeter take that’s perfect for holiday tables, replace the savory spices with 1 teaspoon of cinnamon and toss the oiled cubes with 2 tablespoons of pure maple syrup before roasting. The maple caramelizes beautifully, creating an irresistible glaze.

Spicy Southwest Style: Add 1/4 teaspoon of cayenne pepper and 1/2 teaspoon of cumin to the spice blend for a kicking southwest flavor profile. After roasting, toss with a handful of chopped fresh cilantro and a squeeze of lime juice for brightness.

Mediterranean Sweet Potatoes: Use the base recipe but after roasting, toss the hot sweet potatoes with 2 tablespoons of crumbled feta cheese, 1 tablespoon of pine nuts, and 1 teaspoon of dried oregano. The warm potatoes slightly melt the feta, creating a creamy contrast to the crispy exterior.

Storage and Serving

These Crispy Roasted Sweet Potatoes maintain their delicious flavor when stored properly, though they’re at their crispiest straight from the oven. Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, arrange in a single layer on a baking sheet and warm in a 375°F oven for 5-10 minutes—this helps restore some of the crispiness that may be lost during storage. Avoid microwaving if possible as this will make them soft rather than crispy.

For serving, these versatile sweet potatoes shine in multiple contexts. Serve them as a colorful side dish alongside roasted chicken or grilled steak. They make an excellent addition to grain bowls with quinoa, avocado, and a protein of your choice. For a breakfast twist, top with a fried egg and a sprinkle of green onions—the runny yolk creates a delicious sauce for the crispy potatoes. They’re also perfect for meal prep, adding substance and nutrition to salads and lunch bowls throughout the week.

FAQs

Why aren’t my sweet potatoes getting crispy?
The most common reason is overcrowding on the baking sheet. Sweet potatoes need space around them for hot air to circulate and moisture to escape. Try using two baking sheets if necessary. Also, make sure you’re using the cornstarch—it’s crucial for achieving that crispy exterior.

Can I prepare these in advance?
You can peel and cube the sweet potatoes up to 24 hours in advance. Store them submerged in cold water in the refrigerator, then drain and pat completely dry before proceeding with the recipe. For maximum crispiness, it’s best to roast them right before serving.

Can I use this method for regular potatoes?
Absolutely! This technique works beautifully for regular potatoes as well. The cooking time may vary slightly depending on the variety you choose, so just keep an eye on them.

Are these healthy?
Yes! Crispy Roasted Sweet Potatoes are packed with vitamins, particularly vitamin A, along with fiber and antioxidants. The olive oil adds healthy fats, and the recipe uses minimal added salt while maximizing flavor through spices.

Can I make these in an air fryer?
Definitely! Cook them at 380°F for about 12-15 minutes, shaking the basket halfway through. You might need to work in batches depending on the size of your air fryer, but the results are exceptionally crispy.
