Place beef strips into a large bowl or a ziplock bag.
Add oil, fish sauce, soy sauce, ginger, garlic, sugar, Sriracha, coriander, and 1/4 cup cilantro to the beef and mix well. Marinate for 30 minutes or up to 24 hours in the refrigerator.
Using a set of tongs, place the beef strips in the air fryer basket, laying them side by side and minimizing overlap.
Leave behind as much of the marinade as you can and discard this marinade.
Set your air fryer to 400F for 8 minutes, flipping once halfway.
Remove the meat to a serving tray, top with remaining 1/4 cup chopped cilantro and the chopped roasted peanuts.
