Season the potatoes and onions with salt, black pepper, and paprika (if using). Stir well to combine and cook for an additional 2-3 minutes to let the flavors meld together.
Serve:
Transfer the crispy fried potatoes and onions to a serving dish. Garnish with freshly chopped parsley or chives if desired. Serve hot.
Tips:
Make sure not to overcrowd the pan; fry the potatoes in batches if necessary to ensure they cook evenly and become crispy.
You can add garlic or other spices to enhance the flavor according to your preference.
