Start by removing the steak from the refrigerator at least 30 minutes before cooking. This will help it cook evenly., Pat the steak dry with paper towels to remove any excess moisture, ensuring a nice sear., Season both sides of the steak generously with salt and pepper. You may also enhance the flavor by adding your favorite steak seasoning., Heat a large skillet over medium-high heat. Add a tablespoon of olive oil to the hot pan., Once the oil shimmers, carefully place the seasoned steaks into the skillet. Sear them without moving for about 4-5 minutes for medium-rare., Flip the steaks using tongs and cook for another 3-4 minutes, depending on desired doneness., During the last minute of cooking, add the garlic butter mixture to the skillet. Spoon the melting garlic butter over the steaks as they finish cooking., In a small mixing bowl, combine the softened unsalted butter with minced garlic, chopped parsley, thyme, and a pinch of salt and pepper., Mix until well combined., Once your steaks are cooked to perfection, remove them from the skillet and let them rest for 5 minutes., Reserve the remaining garlic butter in the skillet to enhance the flavor of the pasta sauce., Begin by filling a large pot with water and bringing it to a rolling boil. Add a generous amount of salt to the water., Add the rigatoni pasta and cook according to the package instructions until al dente, usually about 10-12 minutes., Reserve a cup of pasta water before draining the rigatoni. This starchy water will help adjust the sauce’s consistency if necessary., Drain the pasta and set aside., In the same skillet used for the steak, add the olive oil and butter over medium heat, allowing the butter to melt and sizzle., Pour in the heavy cream, stirring continuously until it becomes smooth and heated through., Gradually add the grated Parmesan cheese, whisking constantly until the cheese has melted and the sauce becomes creamy., Stir in garlic powder, salt, and pepper for extra flavor. If the sauce is too thick, add a little reserved pasta water to achieve your desired consistency., Add the cooked rigatoni to the creamy Parmesan sauce, tossing gently to ensure every piece of pasta is coated in the rich sauce., If desired, mix in some of the reserved garlic butter from earlier for extra flavor., Let the pasta heat through for 1-2 minutes on low heat before serving.
