3 Ingredient spaghetti recipe. Literally "cheese and pepper", this minimalist pasta is like a stripped-down mac and cheese. Since this dish has so few ingredients, it is important to use the best quality ingredients you can afford. This dish only takes as long as it takes for the pasta to cook, so be sure to grate your parmesan ahead of time. Save that pasta water, the starchy water is a crucial element to a proper emulsion.
