In a bowl, toss the steak cubes with olive oil, salt, pepper, garlic powder, onion powder, smoked paprika, and Italian seasoning until well-coated.
Cook at 400°F for 5-10 minutes, until the steak bites reach your desired doneness. Shake the basket every few minutes to promote even cooking.
Toss the cooked steak bites in melted butter and sprinkle with fresh parsley before serving.
