Tried doing a supermarket entrecôte today. No herbs, garlic etc., just salted both sides, left it a bit then dabbed it off with kitchen paper and stuck it in the air fryer. 200°C, judged cooking by colour rather than time but it took around 6 minutes for 180g. Best I've eaten in years.
Only drawback was that it took up the whole basket, so cooking for several would be out. Fortunately, MrsT is vegetarian.
Oh aye, it was one we had in the freezer, so a fresh one should be even better.
