01 - Place diced potatoes in a saucepan and cover with cold water. Bring to a boil over high heat, then reduce to medium and simmer 5–7 minutes until just tender. Drain thoroughly and set aside.
02 - Heat 2 tablespoons butter and 2 tablespoons oil in a large skillet over medium-high heat. Add onion and bell pepper, sauté 3–4 minutes until softened and translucent.
03 - Stir in minced garlic and cook 30 seconds until fragrant, being careful not to burn.
04 - Add drained potatoes to skillet. Cook undisturbed 4–5 minutes to develop a golden-brown crust on one side.
05 - Add diced corned beef and smoked paprika. Toss to combine, then press mixture into an even layer. Cook undisturbed 4–5 minutes until bottom crisps and browns. Season with salt and pepper.
06 - Flip hash sections in batches and cook 3–4 minutes until the second side achieves similar crispiness.
07 - Push hash to skillet edges. Add remaining 1 tablespoon butter to center and crack in eggs. Fry to desired doneness—sunny-side up or over-easy recommended.
08 - Sprinkle with fresh parsley and serve immediately while hot and crispy.
