how to cook steak without a bbq
Oven at 500.
If you've got a thick steak... I heat up my cast iron pan until short of smoking. 3 minutes one side, flip and 5 minutes on the other side. Then into the oven for 5 minutes.
Pull it out on a plate and let rest.
Use some good judgement about the timing, depending on the thickness. I feel like the poke test is pretty good for me: when it feels like the same texture as the fleshy part on your hand between thumb and index finger, it is time to pull for medium-rare?
