Porterhouse Steak with Lyonnaise Potatoes

Preheat the oven to 200° C.

Add the oil to a large saute pan over high heat and wait for it to lightly smoke. Add in the potatoes and onions and cook for 8-10 minutes or until you begin to see some dark brown edges on the potatoes and onions.

Season the potatoes with salt and pepper and add in 1/2 the butter over top. Transfer the pan to the oven and cook for 10-12 minutes or until they are browned and cooked through. Finish by deglazing with the white wine vinegar and remaining butter. Mix before serving.

Season the steaks generously on both sides with salt and pepper.

Add the oil to a large cast iron skillet or fry pan and wait for it to lightly smoke. Add in the steaks and turn the heat down to medium-high. Add in the herbs, garlic and butter.

Cook the steak for 5-6 minutes and then flip it over and immediately begin basting it for 2 to 3 minutes.

Remove the steaks and let them rest before slicing and serving alongside the potatoes.
