Trim the tough ends of the asparagus, then wash them thoroughly and pat them dry with a paper towel to ensure they are completely dry.
Place the asparagus evenly on a baking sheet lined with parchment paper. Drizzle with oil and gently toss to ensure they are evenly coated.
In a small bowl, mix nutritional yeast, salt, and garlic powder. Evenly sprinkle the mixture over the asparagus.
Preheat the oven to 200°C (392°F). Roast the asparagus for 15 minutes, until they are slightly crispy on the outside but tender on the inside.
Serve the roasted asparagus on its own or as a side dish, for example, with cooked rice or polenta. We also added tempeh on the side.
