Preheat your oven to 400°F (200°C).
Wash the Yukon Gold potato and dice it into small 1/2-inch cubes to ensure even cooking.
Finely dice the red bell pepper and yellow onion.
In a large oven-safe skillet, heat the olive oil over medium-high heat.
Add the diced potatoes to the skillet and cook for 5-7 minutes, stirring occasionally, until they begin to soften and develop a light golden crust.
Add the diced onion and bell pepper to the skillet and sauté for another 3 minutes until the onion is translucent.
Push the vegetables to the edges of the skillet and add the ground beef to the center, breaking it apart with a wooden spoon.
Sprinkle the smoked paprika, garlic powder, sea salt, and black pepper over the beef and vegetables.
Cook until the beef is fully browned, then stir everything together and transfer the skillet to the preheated oven.
Bake for 10-12 minutes until the potatoes are fork-tender and garnish with freshly chopped parsley before serving.
