I usually do my steaks indoors, dragging out the grill for just the two of us is a bit too much.
The thing is, my method takes a bit of time... Which is a good thing because I usually cook baked potatoes with them.
I season the steaks (usually pretty thick cut, and I've used Strip, Porterhouse, and T-bone) and sear them in a non-stick fry pan over high heat, about a minuite on each side, and 30 seconds on the edges. Once seared I put them on a rack on a sheet pan, and toss them in a 375 degree oven (with the potatoes having been in for about 30 minutes already). They spend between 30 and 45 minutes in the oven. Once done, cover with foil and let rest for 5 minutes.
