Heat the avocado oil in a large cast-iron skillet over medium-high heat.
Add the diced sweet potato to the skillet and cook for 8-10 minutes, stirring occasionally, until tender and the edges are golden brown.
Push the potatoes to the outer edges of the pan and add the ground beef, diced red onion, and red bell pepper to the center.
Cook the beef for 5-7 minutes, breaking it up with a spatula, until fully browned and the vegetables have softened.
Stir the sweet potatoes back into the beef mixture and season with garlic powder, smoked paprika, sea salt, and black pepper.
Use the back of a spoon to create a small well in the hash and crack the egg into the center.
Reduce heat to medium, cover the skillet with a lid, and cook for 2-3 minutes until the egg white is opaque but the yolk is still jammy.
Remove from heat, garnish with chopped fresh parsley, and serve immediately.
