Preheat the oven to 375°F (190°C). Grease a baking dish or ovenproof skillet with vegetable oil.
Grate the potatoes and carrot, then use a clean kitchen towel or paper towels to squeeze out excess moisture. This ensures a crispy texture.
In a large bowl, mix the grated potatoes, carrot, chopped onion, spring onions, eggs, and optional cheese. Season with salt, pepper, garlic powder, and paprika. Stir well to combine.
Transfer the mixture into the greased baking dish, spreading it evenly. Press it down slightly to help it hold together.
Bake for 30-40 minutes, or until the top is golden brown and crispy.
Let it cool for a few minutes before slicing. Serve warm with your favorite dipping sauce, sour cream, or yogurt.
