Add the chopped onion and garlic to a medium non-stick pan together with the butter and olive oil. Then season with a pinch of salt and pepper.
Place the pan over medium-high heat until the butter has melted. Then gently cook the onion and garlic for 3 minutes without browning. Peel the potatoes and rinse them. Then dice them up finely and also add this to the pan.
Stir well. Put a lid on the pan and bake the hash for 5 more minutes. The potato should be nicely golden brown on the edges. Season with a pinch of spicy paprika powder.
