01 - Preheat your oven to 425°F (220°C). Line two baking sheets with parchment paper to prevent sticking.
02 - Peel the sweet potatoes if desired, then cut them into uniform 1/4-inch thick fry shapes.
03 - In a large bowl, toss the sweet potato fries with olive oil, ensuring each piece is evenly coated.
04 - In a separate small bowl, thoroughly mix together the smoked paprika, garlic powder, onion powder, oregano, thyme, cayenne pepper, black pepper, and salt.
05 - Sprinkle the prepared spice blend over the oiled sweet potato fries. Toss them again to ensure the spices adhere evenly.
06 - Spread the seasoned fries in a single layer across the prepared baking sheets. Avoid overcrowding the sheets to promote even crisping.
07 - Bake for 15 minutes. Carefully flip the fries and rotate the baking sheets. Continue baking for an additional 12 to 15 minutes, or until the edges are golden and crispy.
08 - Remove from oven and serve immediately. Consider offering a favorite dipping sauce as an accompaniment.
