Preheat your oven to 400°F and line a large rimmed sheet pan with parchment paper for easy cleanup.
Peel and dice the sweet potato into small 0.5-inch cubes to ensure they roast quickly and evenly.
Place the sweet potato cubes on the sheet pan, toss with 0.25 tbsp of olive oil, sea salt, and black pepper, then roast for 12 minutes.
While the potatoes roast, whisk together the honey, soy sauce, minced garlic, red pepper flakes, and the remaining 0.5 tbsp of olive oil in a small bowl.
Cut the chicken breast into 1-inch bite-sized pieces and trim the woody ends off the asparagus spears.
Remove the pan from the oven, add the chicken and asparagus, then drizzle the honey-garlic glaze over everything and toss with tongs to coat.
Return the sheet pan to the oven and roast for an additional 10-12 minutes until the chicken is fully cooked and the glaze is bubbling and thickened.
