If your sauce ends up in a pool at the bottom of the bowl, the recipe is not the problem. The finishing step is. In an Italian kitchen the pasta is never sauced in the bowl. It is finished in the pan.
Pasta water is an ingredient
The water pasta cooks in carries dissolved starch. That starch is the emulsifier that binds fat and water into a sauce that clings. Throw the water away and you have thrown away the binder. Keep a mugful before you drain, every time.
Salt the water properly
Roughly ten grams of salt per litre, added once the water boils. Pasta only seasons from the inside during those few minutes. Under-salted pasta cannot be fixed at the table, and over-salted water concentrates as it reduces in the pan.
Drain early and finish in the pan
Pull the pasta a good minute or two before the packet time, while it still has a firm core. Move it straight into the pan with the sauce over medium heat, add a splash of the cooking water, and toss hard. The pasta finishes cooking in the sauce and absorbs flavour instead of water. This is the step almost every home cook skips.
Toss, do not stir
Tossing creates the agitation that emulsifies fat, starch and water. Stirring just moves things around. If you cannot flip a pan, use tongs and lift the pasta repeatedly through the sauce. You will see the sauce change from loose and separated to glossy and thick within about thirty seconds.
Match the shape to the sauce
Long thin shapes suit oil-based and light sauces. Tubes and ridges suit chunky ragu because the sauce lodges in the shape. This is not folklore. It is surface area. A sauce that has nothing to hold onto will slide off no matter how well you emulsify it.
Frequently asked questions
How much pasta water should I save?
About a cup for four portions. You will rarely use all of it, but running out mid-toss means the sauce breaks.
Should I add oil to the pasta water?
No. Oil coats the pasta and stops sauce sticking, which is the opposite of what you want.
Should I rinse cooked pasta?
Never, unless you are making a cold pasta salad. Rinsing washes off the surface starch that helps the sauce cling.
How undercooked should the pasta be when I drain it?
Firm enough that there is a visible pale core when you bite through. It will finish in the pan in about ninety seconds.
