Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Pat the chicken breast dry with a paper towel and cut it into 1-inch bite-sized pieces to ensure even cooking.
Wash the red potatoes and cut them into 1/2-inch cubes so they roast at the same rate as the chicken.
In a large mixing bowl, combine the chicken pieces, cubed potatoes, and corn kernels.
Drizzle with extra virgin olive oil and sprinkle with dried rosemary, dried thyme, garlic powder, sea salt, and black pepper.
Toss everything thoroughly until the ingredients are evenly coated in the oil and herb mixture.
Spread the mixture in a single layer on the prepared baking sheet, making sure not to overcrowd the pan.
Roast for 20 to 25 minutes, tossing the ingredients halfway through, until the chicken is cooked through and the potatoes are tender and browned.
Remove from the oven and garnish with freshly chopped parsley before serving.
