Preheat the oven to 180 degrees Celsius/ 350 degrees Fahrenheit.
Bring a large pot of water to a boil. While you wait for the water to cook, clean the asparagus and remove its lower part. Cut each stalk in 3 pieces.
Once the water boils, add salt generously and cook the pasta according to the package instructions. Add the asparagus to the pasta pot during the last 4 minutes of the cooking time. Drain everything well.
While the pasta cooks, chop the chicken breast into bite-sized pieces. Heat 1 tablespoon olive oil in a large pan and fry the chicken pieces until golden brown and cooked through, 3-4 minutes. Add some garlic powder, salt and pepper to taste.
Place the pasta and asparagus into a casserole dish. Add the chicken, 3 tablespoons olive oil, and half of the Parmesan. Mix well, adjust the taste with salt and pepper, level and sprinkle with the remaining Parmesan.
