Ingredients
-
3 large sweet potatoes (about 2.5 lbs/1.13 kg), peeled and cut into ¾-inch cubes
-
3 tablespoons olive oil or avocado oil
-
1½ teaspoons garlic powder
-
1 teaspoon smoked paprika
-
1 teaspoon ground cumin
-
¾ teaspoon sea salt
-
½ teaspoon black pepper
-
¼ teaspoon cayenne pepper (optional, for heat)
-
Fresh herbs for garnish (optional): chopped parsley or cilantro
Instructions
-
Preheat your oven to 425°F (220°C) and line one or two large baking sheets with parchment paper or lightly grease them with oil. Wash and peel the sweet potatoes, then cut them into uniform ¾-inch cubes. Pat the cubes dry with paper towels to remove excess moisture.
-
Transfer the dried sweet potato cubes to a large mixing bowl. Drizzle with olive oil and add garlic powder, smoked paprika, cumin, salt, black pepper, and cayenne if using. Use your hands or a large spoon to toss everything together, ensuring each cube is evenly coated with oil and seasonings.
-
Spread the seasoned cubes across your prepared baking sheet in a single layer, leaving at least ½ inch of space between pieces. If they don’t all fit comfortably, use a second baking sheet rather than crowding. Position the baking sheet on the middle rack of your preheated oven.
-
Roast for 15-20 minutes without disturbing the cubes, allowing the bottoms to develop a deep golden crust. After this initial roasting period, remove the pan from the oven and use a metal spatula to flip the cubes, exposing the unbrowned sides. Return to the oven and continue roasting for another 15-20 minutes.
-
Your cubes are ready when they’re golden brown on multiple sides, fork-tender inside, and sporting crispy edges. For extra caramelization, broil for the final 2-3 minutes while watching closely. Remove from the oven, taste, and adjust seasoning if needed. Garnish with fresh herbs if desired and serve immediately.
Notes
-
Cut sweet potatoes into uniform ¾-inch cubes for even cooking. Inconsistent sizing leads to some pieces burning while others remain undercooked.
-
Don’t overcrowd the pan. Spread cubes in a single layer with space between each piece, using two baking sheets if necessary. Overcrowding causes steaming instead of roasting.
-
Pat cubes dry before seasoning to remove excess moisture, which helps achieve maximum crispiness.
-
For a sweet and spicy variation, toss roasted cubes with 2 tablespoons maple syrup, ½ teaspoon cinnamon, and a pinch of cayenne during the last 5 minutes of roasting.
-
Store leftovers in an airtight container in the refrigerator for up to 5 days. Reheat in a 400°F oven for 8-10 minutes to restore crispiness.
