Boil Potatoes:
In a pot of salted water, boil the diced potatoes until they are just tender 10-15 minutes. They should be slightly firm when pierced with a knife. Drain and set aside.
Once the potatoes are cooled, slice them in 1/4 inch slices.
Sauté Vegetables:
In a large skillet, heat the cooking oil and butter over medium heat. Add the corned beef, chopped onion, red bell pepper, green onions and parsley. Sauté until softened and slightly caramelized approximately 3 minutes.
Add Potatoes:
Incorporate the boiled diced potatoes into the skillet. Allow them to cook with the other ingredients, turning occasionally to achieve a golden brown colour.
Seasoning:
Sprinkle smoked paprika, garlic powder, seasoned salt, salt, and black pepper over the mixture. Adjust seasoning to taste. Stir well to evenly distribute the flavours.
Serve:
Once everything is well-cooked and flavourful, serve the corned beef hash hot. It pairs well with a fried or poached egg on top, and you can also serve it with toast or crusty bread.
