Question: how much sauce for 2 oz pasta?
Answer: When calculating how much sauce for pasta per person, generally about 2 to 4 ounces (1/4 to 1/2 cup) of sauce for each 2 ounce (about 1 cup cooked) serving of pasta would be needed. For pesto sauces, use about one jar of 5.6-ounce sauce for a 16-ounce package of pasta.
