What is al dente?
In Italian, al dente literally translates to “to the tooth”. This phrase is used to describe the texture of pasta when it is cooked until tender but firm and chewy when you bite into it. This is usually approximately 2 minutes less than most package cook times. Al dente pasta holds its shape better and in this recipe, is easier to work with when stuffing the shells with the cheese filling. Al dente pasta also contains more starches which allows the sauce to stick to it better.
Al dente pasta is actually more nutrient-dense than fully cooked pasta because the starch molecules have not been fully released into the boiling water. This allows them to be slowly digested by your body which in turn lowers the glycemic index, meaning you will experience less of a blood sugar spike when consuming pasta prepared this way.
