How Much Spaghetti Sauce Does It Take to Feed 100 People?

It takes about 37 1/2 cups of a basic tomato or marinara sauce to supply enough sauce for 100 portions of dried pasta. Fresh pasta requires about 56 1/4 cups of sauce to feed 100 people.

The recommended ratio of sauce to pasta is 1 1/2 cups sauce to 1 pound of pasta. One pound of dried pasta or 1 1/2 pounds of fresh pasta feeds four adults. Oil-based sauces are paired with pasta in smaller portions with a recommended ratio of 1 cup sauce to 1 pound of pasta. Italian cooking experts warn against oversaucing pasta. There should be just enough sauce to coat the pasta.
