Dice the Russet potato into small, uniform 1/2-inch cubes to ensure even cooking.
Heat the extra virgin olive oil in a large non-stick skillet over medium-high heat.
Add the diced potatoes to the skillet and season with half of the sea salt and black pepper.
Cook the potatoes for 8-10 minutes, stirring occasionally, until they are tender on the inside and golden-brown on the outside.
Add the diced yellow onion and red bell pepper to the skillet, sautéing for 3-4 minutes until softened.
Push the potato and vegetable mixture to the outer edges of the skillet and place the ground beef in the center.
Break the beef apart with a spatula and season it with the remaining salt, pepper, garlic powder, and smoked paprika.
Cook the beef until it is completely browned and cooked through, approximately 5-7 minutes.
Toss all ingredients together in the skillet and cook for an additional 2 minutes to allow the flavors to meld and the beef to crisp slightly.
Remove from heat, garnish with freshly chopped parsley, and serve warm.
