  1. Break the spaghetti in half and add to the pot. Top with the marinara sauce and water. Stir around very gently until the pasta is covered.
  2. Lock and seal the lid. Cook at high pressure for half the pasta cooking time on the package, minus 1 minute. (So, if the directions say 9-11 minutes, you’ll cook it for about 4 minutes. I would recommend doing the least amount of time, so your pasta doesn’t get overcooked and mushy.)
  3. Use a quick release of the pressure when cooking time is through. Be sure to cover the spout with a dish towel to minimize splatters. (I didn’t have any when I tested this, but you never know.)
  4. Serve warm and topped with shredded Parmesan cheese.
