01 - Place diced potatoes in a saucepan and cover with cold water. Add a pinch of salt, bring to a boil, then reduce heat and simmer for 4-5 minutes until just tender but not falling apart. Drain well and set aside.
02 - Heat 1½ tablespoons butter and 1 tablespoon oil in a large skillet over medium-high heat. Add drained potatoes in a single layer. Cook undisturbed for 5-7 minutes until golden and crisp on one side. Flip and cook another 3-4 minutes until evenly browned. Remove to a plate.
03 - In the same skillet, add remaining butter and oil. Sauté onions and bell pepper over medium heat for 3-4 minutes until softened and fragrant.
04 - Add corned beef, smoked paprika, salt, and pepper to the skillet. Stir and cook for 2-3 minutes until heated through and well combined.
05 - Return crispy potatoes to the skillet. Stir everything together, pressing the hash down slightly to encourage browning. Cook undisturbed for 4-5 minutes, then gently flip sections and brown the other side for another 3-4 minutes until crispy throughout.
06 - Stir in parsley, taste, and adjust seasoning as needed. Garnish with extra parsley and serve hot.
07 - In a separate pan, fry eggs to your liking and serve atop the hash for a complete breakfast.
