In a large pot of boiling salted water, cook pasta according to package directions. Drain and set aside.
Coat both sides of the steak with oil and season generously with steak seasoning.
Preheat a cast iron skillet or nonstick pan on medium heat. Once hot add about a teaspoon of oil to the pan. Get a dark char on both sides of the steak to your desired temperature using a thermometer (see below). Once done set on a cutting board to rest.
Add the cream and blue cheese to the pan over medium heat and bring to a simmer. Let simmer until the cream reduces and thickens. The sauce should coat the back of a spoon, not clumpy or too thin that it runs off. Toss the pasta in the sauce. Taste and adjust the seasoning with salt and pepper if needed.
Slice the steak against the grain and serve over the top of the pasta with bread on the side. Garnish with parsley.
