Preheat your oven to 200 degrees Celsius.
Peel 500 grams of sweet potatoes and cut them into long, thin strips.
In a large bowl, mix the sweet potato strips with 2 tablespoons of olive oil, 1 teaspoon of salt, and 1/2 teaspoon of black pepper.
Arrange the sweet potato strips in a single layer on a baking tray lined with parchment paper.
Bake in the preheated oven for 15 minutes. Then, flip the fries and bake for another 10-15 minutes until they are crispy and golden brown.
Remove from the oven and let them cool for a few minutes before serving.
