One reason spaghetti is ideal for both a single-serving meal and larger dinners is that it is relatively easy to prepare and serve. A problem encountered while making spaghetti is the pasta sticking to itself and the cooking pot. While this does not have an impact on the taste of the food, clumped pasta is more difficult to eat. The key to keeping spaghetti warm without sticking is to ensure you do not overcook or dry out the pasta.
Undercook the spaghetti by a minute or two. For example, if the cooking instructions state to cook the pasta for 7 minutes, cook it for 5 minutes before advancing to the next step.
Dump the spaghetti into a colander, but leave a small amount of hot water in the bottom of the pot.
Rinse the pasta in the colander with cool water to halt the cooking process. This prevents the spaghetti from overcooking.
Place the spaghetti back inside the pot. Then, pour a small amount of olive oil into the pot. The amount of oil needed depends on the amount of spaghetti inside the pot.
Use tongs or your hands to coat the spaghetti with the oil. Add more oil to the pot, if needed, until all of the pasta is coated.
Place the pot back on the stove. Turn the stove to its absolute lowest setting.
Cover the pot. Stir every 5 to 10 minutes to keep the spaghetti evenly coated with water and oil. The spaghetti absorbs the moisture and it then finishes cooking. The lid on the pot prevents the pasta from drying out.
Place the covered pot inside of a insulated bag if transporting the pasta. The bag prevents the pasta from cooling and the moisture inside the pot keeps the spaghetti from sticking.
