Prepare pasta according to package. While waiting for the pasta to boil, gather your carrots, celery, red onion, frozen peas, ham and cheddar cheese. Set aside
To make the dressing, whisk together ranch mix, mayo and milk. Mix until all lumps are gone.
Once pasta is done, drain and let cool for a couple minutes. Once cooled, mix in carrots, celery, red onion, frozen peas, ham and cheddar cheese.
Next pour dressing over the pasta salad, and stir gently until well combined. Cover and refrigerate for at least 1-2 hours before serving.
Right before serving, give your Creamy Ranch Pasta Salad a couple more stirs to mix in any of the dressing that had settled at the bottom.
