The recommended cooking time for penne pasta can vary depending on the brand and type of pasta you are using. In general, penne pasta takes around 11-12 minutes to cook in boiling salted water, but it's always best to refer to the instructions on the pasta package for the exact cooking time and follow them carefully.
To cook penne pasta, fill a large pot with water, add a generous amount of salt, and bring it to a rolling boil. Then, add the penne pasta to the boiling water and stir occasionally to prevent the pasta from sticking together. Cook the pasta until it's al dente, which means it's cooked through but still slightly firm to the bite.
After the pasta is cooked, drain it in a colander and rinse it briefly with cold water to stop the cooking process. Then, you can use the cooked penne pasta in your favorite pasta dish.
