Peel the sweet potato and dice it into uniform half-inch cubes to ensure even cooking.
Heat a large cast-iron skillet over medium-high heat and add the ground beef to the dry pan.
Cook the beef while breaking it into small crumbles with a wooden spoon until it is thoroughly browned and no longer pink.
Use a slotted spoon to remove the cooked beef from the skillet and set it aside on a plate, leaving any rendered fat in the pan.
Add the extra virgin olive oil to the skillet and then add the sweet potato cubes in a single layer.
Cook the potatoes undisturbed for 4 minutes to allow a crispy crust to form, then stir and cook for another 4 minutes until tender.
Add the diced yellow onion and red bell pepper to the skillet, sautéing for 3 to 5 minutes until the vegetables are soft and fragrant.
Return the browned beef to the skillet and sprinkle the garlic powder, smoked paprika, sea salt, and black pepper over the mixture.
Toss all ingredients together for 2 minutes to fully combine the flavors and ensure the beef is heated through.
Remove the skillet from the heat and garnish the hash with freshly chopped parsley before serving hot.
