Add 1 lb of penne pasta, 4 cups water, and 2 teaspoons of salt to your instant pot. Set it to, “pressure cook,” on high for 5 minutes.

Once it’s done, follow the quick-release cycle (you can find this in your IP guide, or online easily).

I’ve always quickly stirred in a tablespoon of olive oil, or white wine, to get the noodles up from the bottom and prevent any from sticking.
And you’re done! Now you’ve got around 4 to 5 servings of noodles at your fingertips.
