Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Slice the sweet potato into 1/4-inch thick rounds and trim the woody ends off the asparagus spears.
Pat the turkey cutlets completely dry with a paper towel to ensure the herb mixture sticks and the meat browns nicely.
In a small bowl, whisk together the olive oil, sea salt, black pepper, rosemary, thyme, and garlic powder until well combined.
Place the turkey, sweet potato rounds, and asparagus on the baking sheet in a single layer, ensuring they are not overcrowded.
Brush the herb and oil mixture evenly over both sides of the turkey cutlets and toss the vegetables to coat.
Bake for 15-18 minutes, or until the turkey reaches an internal temperature of 165°F and the sweet potatoes are fork-tender.
Remove from the oven and let the turkey rest for 3-5 minutes before serving to ensure every bite is succulent and juicy.
