You sear both sides for 30-45 seconds and then let the steak rest for about 2 minutes, and then repeat until you reach the internal temp you want. Usually about 3 or 4 times for a reasonably thick steak.
I can highly recommend this method and it's also good for cooking large numbers of steaks because you can do 2 or even 3 batches at the same time with the same cast iron pan.
Just make sure to save those juices that drip down for your pan sauce if you are making one!
The run included mustard as a base with lots of the predictable spices.
Put a cast iron skillet (which holds lots of heat) in oven at 500F on the top rack. Once it's hot, add the steak and turn on the broiler.
Flip 1/2 way through. Takes 6-12 mins. You can get a well-seared exterior with lots of crispy, browned fat, and the inside is still pink.
Tastes great! (Very smoky.)
I preheat 250-300 and watch a remote meat thermometer until the steak is 95% to desired temp. Usually takes 30-45 minutes. Then I crank up a skillet with ghee until it just starts smoking (~500F) and sear the hell out of the steaks for only a minute on each side. Perfect crust every time. Let rest for about 10 minutes.
Personally, I like using butter or ghee. Aside from the taste, it increases and distributes the heat transfer more evenly across the surface which provides a more uniform sear. If you do use oil, I'd recommend using ghee or refined olive oil and make sure to "temper" it first (allow it to warm with the skillet).
I do it just because I don't have to worry about doneness later - the inside is already cooked, just sear it and it's done.
I know a lot of people use a torch, but personally I like the skillet. Seems less fiddly and generally faster for a steak.
Maybe I’m just paranoid and missing out on some flavor but I don’t cook anything other than fish below 135F to kill any bacteria. https://www.amazingfoodmadeeasy.com/info/sous-vide-safety/mo... (Update) I’ve seen other reliable sources suggest 130F for 2+ hours is safe.
That's funny; fish is the one thing I'm ultra paranoid about. Many parasites survive in fish up to 145 F, and parasites are much more common than you might think. The gross out factor convinced me to switch away from wild salmon to farmed. Sushi grade fish is a bit different since it's required to be flash frozen in the U.S., but you're still eating parasite corpses (which doesn't bother some people, but personally makes me a bit squeamish).
As a society we live bathed in feces. The fecal-oral route is the most common way in which we get food poisoning. Yet it's only when the feces is pathogen-laden that we actually get food poisoning.
Worrying about dead parasites seems a little pointless when most people don't even wash their hands correctly.
For me anyhow, beef at 135 is decent (pork and chicken at 145 is my goto FWIW), but lots of fish tastes rubbery and just bad when cooked above 125 or so. I don't eat a ton of fish so I gamble on that.
He has a fairly exhaustive explanation of the different food-born microorganisms and how to kill them.
Anyways, go get at least one!
To piggyback on this comment, one reason I love using a cast iron skillet for steaks is so I can get a nice fond and deglaze for a sauce to go over the steak/potatoes/whatever. It's like a freebie!
Ahh, that could make sense, yes.

Yup. Pan sauces are free flavor that you get with every pan meal :) Works well with stainless steel skillets too.
One solution to having to broil them for too long might be to finish your sous vide cook, then chill them in an ice bath, and only broil once cold. That way the lower meat temp protects against the broiler overcooking the inside.
