Whisk together your freshly squeezed orange juice, aminos/soy sauce, honey/maple syrup, and Worcestershire sauce.
Pour this marinade over roast in a large bowl or dish and marinate, covered, in the fridge for 8-24 hours.
Remove from the fridge for about 30 minutes before cooking.
Preheat your air fryer to 400 degrees f.
Drain and discard excess marinade.
Place roast in your air fryer basket.
Sprinkle and rub generously with sea salt and pepper over the entire roast.
Air fry for 30 minutes at 400 degrees f. flipping your roast over halfway through cooking time.
Remove your roast from air fryer and allow it to rest for at least 5-10 minutes.
Meanwhile, toss sweet potato cubes with oil and seasonings.
Place sweet potato cubes in your air fryer at 400º Fahrenheit for 10-12 minutes while your roast is resting. Toss once during cooking time so they all get nicely browned.
Slice your roast against the grain and serve with your sweet potatoes.
Garnish with freshly chopped herbs if desired.
Enjoy!
