How to Avoid Watery Spaghetti

If using fresh tomatoes, use a meaty variety. It will eject a less amount of water. This is why Roma tomatoes are so much sought after. While heirloom tomatoes are excellent in salads, they are not the ideal for spaghetti sauce.

Others find that the sauce gets excessively watery when combined with pasta. This is because if the sauce is not thoroughly drained and the pasta is still wet, the sauce gets weaker.


If you lack the patience to wait for spaghetti sauce to simmer, you may thicken the sauce using cornstarch. This will save you time while still producing the desired thickness of sauce. This technique is simple to implement. Simply combine 3 tablespoons cornstarch and 1/3 cup water. Add the cornstarch and whisk it into the tomato sauce mixture when it is nearly ready. Allow several minutes for cooking.
