When adjusting the pressure cooking time for the kind of pasta you are making, you can cut the time in half, as stated on the pasta's packaging. For instance, if you are using an instant pot, it needs to be cooked on the stove for 8 minutes, but with the pressure cooker, reduce the time to 4 minutes. If you prefer al dente pasta or gluten-free pasta, cut the time for one more minute. When preparing pasta beforehand, pressure cooks it for only 3 minutes as it will absorb moisture and become softer.
