How do you cook spaghetti for 200 people?

To cook spaghetti for 200 people, you'll need about 20 pounds of dry spaghetti, as a typical serving is about 2 ounces per person. Start by boiling large pots of salted water, using at least two or three pots to accommodate the volume. Cook the spaghetti in batches according to the package instructions, usually around 8-12 minutes until al dente, then drain and toss with olive oil to prevent sticking. Serve with your choice of sauce and toppings, ensuring a consistent distribution for all guests.
