Crispy on the outside, tender inside, these Spicy Roasted Sweet Potatoes are tossed in a blend of warming spices and olive oil. Quick, healthy, and flavorful, they’re perfect as a side for any meal or for easy meal prep throughout the week.
Prepare the Sweet Potatoes: Start by washing your sweet potatoes thoroughly under running water to remove any dirt. Use a vegetable peeler to peel off the skin completely, revealing the bright orange flesh underneath. Next, place the peeled sweet potatoes on a clean cutting board and cut them into evenly sized cubes, about 1-inch pieces. Uniform cubes ensure even cooking, giving you perfectly tender and lightly crispy potatoes.
Preheat the Oven: Preheat your oven to 425°F (220°C). A properly preheated oven ensures the sweet potatoes roast evenly and develop a slightly crispy exterior while staying soft and fluffy inside. Line a large baking sheet with parchment paper or lightly grease it with olive oil to prevent sticking.
Coat with Olive Oil: Transfer the cubed sweet potatoes into a large mixing bowl. Drizzle 2 to 3 tablespoons of olive oil over the potatoes. Using clean hands or a spatula, gently toss the cubes to coat each piece thoroughly in oil. The olive oil not only helps the spices stick but also creates a golden, crisp exterior when roasted.
Mix the Spices: In a small bowl, combine all your seasonings: 1 teaspoon cumin, 1 teaspoon chili powder, ¼ teaspoon onion powder, ½ teaspoon smoked paprika, 1 teaspoon garlic powder, ½ teaspoon salt, ¼ teaspoon black pepper, and optional ¼ teaspoon cayenne pepper for extra heat. Stir them together until evenly blended.
Season the Sweet Potatoes: Sprinkle the spice mix evenly over the olive oil-coated sweet potato cubes. Use your hands or a large spoon to toss the potatoes until every cube is coated with the aromatic spice blend. Take a moment to smell the fragrant mix—it will give you a preview of the delicious flavor in every bite.
Arrange for Roasting: Spread the seasoned sweet potato cubes in a single, even layer on the prepared baking sheet. Avoid overcrowding the pan, as giving the cubes space allows them to roast properly, producing a crisp exterior. If necessary, use two baking sheets to maintain proper spacing.
Roast in the Oven: Place the baking sheet in the preheated oven and roast for 25 to 35 minutes. About halfway through, carefully use a spatula to turn the sweet potatoes for even browning. The cubes should turn slightly golden on the edges while remaining tender inside. You can test doneness by piercing a cube with a fork—it should slide in easily.
Final Crisping (Optional): For extra crispiness, you can switch the oven to broil for the last 2–3 minutes of cooking. Keep a close eye to prevent burning. This step gives the sweet potatoes a beautiful caramelized surface while maintaining a soft, flavorful interior.
Serve and Enjoy: Once roasted to perfection, remove the baking sheet from the oven. Let the sweet potatoes cool for a few minutes. Transfer them to a serving dish and serve immediately. These spicy roasted sweet potatoes make a wonderful side for weeknight dinners, holiday meals, or even meal prep for the week. Garnish with fresh herbs like parsley or cilantro if desired.
Optional Storage Tips: If you have leftovers, allow them to cool completely before transferring to an airtight container. Store in the refrigerator for up to 4 days. Reheat in the oven at 375°F (190°C) for 10–12 minutes to maintain their crispiness, or microwave if you prefer a softer texture.
Notes
Choose firm, evenly sized sweet potatoes for consistent roasting.
Peeling is optional; unpeeled potatoes give a rustic texture, peeled cubes hold spices better.
Avoid overcrowding the baking sheet to ensure crispy edges.
Adjust spices according to your preferred heat level; a little cayenne goes a long way.
Toss cubes thoroughly in olive oil before seasoning for even flavor distribution.
Roast until golden brown on the edges but tender inside for the perfect texture.
Let roasted potatoes rest a few minutes after baking to enhance natural sweetness.
