Make the Alfredo sauce first. In a saucepan, heat the butter and cream over medium heat just until it begins to bubble. Then turn the heat down to low and simmer for 15 minutes.
1/2 cup unsalted butter, 2 cups heavy cream
Remove from heat. Stir in the Parmesan. Then add in salt, pepper, nutmeg and parsley. Set aside. The sauce will thicken a bit as it sits while you prepare the rest of the meal.
1 1/2 cups Parmesan cheese, freshly and finely grated, salt and pepper to taste, pinch of fresh nutmeg, 2 Tbsp. fresh parsley, chopped
Make the steak. You can either cook it however you like best, or this is what I do for Filet: Preheat the oven to 400°.
Sirloin, Filet, New York Strip, Ribeye, etc.
Season the steaks with salt and pepper on both sides. In a large cast iron skillet over medium-high heat, heat the oil. Add the steaks when the oil is hot and sear for 2-3 minutes. Flip the steaks and add the butter. Baste for another 3-ish minutes. Check the temperature of your steak at this point so you know how long to keep it in the oven.
1 Tbsp. olive oil, Kosher salt, Black pepper, 2 Tbsp. unsalted butter
Transfer the steaks into the oven for 3-5 more minutes, depending on how you like your steak. You may need just a little more or less time depending on if you like it medium-rare, more medium or medium well. Remove the steak from the oven and transfer to a cutting board. Let rest a few minutes before slicing.
Cook the fettuccine according to package directions, drain and toss the cooked pasta in the Alfredo sauce.
1 lb. fettuccine pasta
Divide the pasta between plates or bowls and top with the sliced steak. Garnish with more parsley, cheese and black pepper. Enjoy!
