Ideal for pan searing, the porterhouse steak gives a premier restaurant presentation but is easily over or undercooked due to its size. I’ve got your solution; this is the perfect pan-seared porterhouse steak.

Try this trick for a Perfect Pan Seared Porterhouse. And don't forget the fried onions on top, this is an epic date night!

Where a t-bone is perfect for grilling, trust me, the porterhouse, a big brother to the ribeye steak, is begging for a pan sear.

What is a Porterhouse Steak? 

A T-bone, strip and tenderloin, steak divided by the defining ‘T‘ shaped that is greater than 1 1/4″ thick and possibly next to only the Cowboy Steak – one of the prettiest for plating. Ideal for pan searing, the porterhouse steak gives premier restaurant presentation but is easily over or undercooked due to its size, leaving you staring down an expensive giant slab of beef.  

Luckily, using both the cooktop and the broiler, the mystery of the cast iron seared porterhouse steak is something any date night can take on.

Rustic wood board, cast iron server, and a Porterhouse so big it wouldn't fit on a plate. That's what I'm talking about.

There is something about the steak that reminds me of cheap dates and former flings. Coming out sizzling, but often not living up to expectations and an egregious waste of time and money. A steak is a thing to be cherished. A special event. It’s a well cut prime slab of choice meat that was aged and cared for before it even hit your kitchen counter.

There are the bulk rough cuts of a busy market butcher, which should be reserved for those hot and fast nights that we have all had. And then, there are the clean patient cuts that a butcher is going to give you when you really know what it is you are looking for.

No one’s going to turn down the quick cheap cut, over time and as your taste evolves, you learn how to make those thick prime cuts worth every penny you spent on them.
