Preheat your oven to 425°F (220°C).
Peel the sweet potato (if preferred) and cut it into small, bite-sized cubes.
Thinly slice the yellow onion for even caramelization.
In a bowl, toss the sweet potato cubes with half the olive oil, paprika, salt, and pepper until evenly coated.
Spread the sweet potato cubes on a rimmed baking sheet lined with parchment paper. Roast in the preheated oven for about 20-25 minutes, stirring halfway through, until crispy and tender.
While the sweet potatoes roast, heat the remaining olive oil in a skillet over medium heat. Add the sliced onions and a pinch of salt, cooking slowly for 10-12 minutes until they become deeply caramelized. Stir occasionally to prevent burning.
Season the chicken breast lightly with salt and pepper. In a separate nonstick pan, over medium-high heat, cook the chicken breast for about 5-6 minutes per side or until fully cooked and nicely browned. Once done, slice the chicken into strips or bite-sized pieces.
Once all components are ready, combine the roasted sweet potato cubes, caramelized onions, and sliced chicken breast. Toss gently to mix the flavors.
Serve warm, and enjoy your flavorful, protein-packed hash that works beautifully for breakfast, lunch, or dinner.
