Prepare the sweet potatoes by peeling and grating them finely.
In a large skillet, heat the olive oil or butter over medium heat.
Add the chopped onion and bell pepper to the skillet, sautéing until softened (about 3-4 minutes).
Stir in the minced garlic and paprika, cooking for another minute until aromatic.
Add the grated sweet potatoes, season with salt and pepper, and stir to combine everything thoroughly.
Press the mixture into an even layer in the skillet, allowing it to cook undisturbed for about 5 minutes.
Carefully flip portions of the hash and let the other side brown for an additional 5 minutes.
Once both sides are crispy, taste and adjust seasoning if necessary before serving warm.
