Dice the russet potato into small 1/2-inch cubes to ensure they cook through and crisp up quickly.
Heat the olive oil in a large non-stick skillet over medium-high heat and add the potato cubes in a single layer.
Cook the potatoes for 8-10 minutes, stirring occasionally, until they are tender and have developed a golden-brown exterior.
Add the diced yellow onion and red bell pepper to the skillet, sautéing for 3-4 minutes until the vegetables are softened.
Push the potato and vegetable mixture to the sides of the pan and add the ground beef to the center.
Break the beef apart with a spatula and season the entire skillet with garlic powder, smoked paprika, sea salt, and black pepper.
Cook until the beef is fully browned and the juices have mostly evaporated, allowing the beef to slightly crisp against the pan.
Create a small well in the center of the hash, crack the egg into it, and cover the pan for 2-3 minutes until the egg white is set.
Garnish the skillet with freshly chopped parsley and serve immediately while hot.
