Which should finish cooking firsts pasta or Pasta sauce?

The pasta sauce should finish cooking first.

When cooking pasta, it is important to cook the pasta according to the package directions. Most pasta takes around 8-12 minutes to cook. Pasta sauce, on the other hand, can take anywhere from 15-30 minutes to cook, depending on the recipe.

If you cook the pasta sauce first, you can then add the cooked pasta to the sauce and let it simmer for a few minutes to allow the flavors to meld together. This will also help to prevent the pasta from overcooking.
