Step 1: Cook pasta according to package instructions. Once finished cooking, remove from heat and leave in the cooking water for a few minutes (save the water, as it will be used to thicken the sauce).

Step 2: In a pan, add the butter over low heat until melted.

Step 3: Using a slotted spoon, drain the pasta and add into the pan with the butter. Toss well to combine.

Step 4: Pour 2/3 cup of the pasta cooking water into the pan. Add the parmesan cheese. Stir well, the sauce will thicken as it cooks.  If sauce is too thick, add an additional 2 tablespoons of the pasta cooking water at a time to thin out the sauce.

Step 5: Once sauce has reached the desired thickness, add in the black pepper.

Step 6: Serve the rigatoni hot, topping with an extra sprinkle of parmesan cheese and fresh cracked black pepper.
