Cook the Pasta: Boil the pasta in salted water according to the package instructions. Drain and rinse with cold water to stop the cooking process. Transfer to a large bowl.
Prep the Ingredients: While the pasta cooks, chop the pickles, dill, and onion, and shred the cheese.
Make the Dressing: In a separate bowl, whisk together the mayonnaise, sour cream, pickle juice, salt, and pepper until smooth.
Combine Everything: Add all the ingredients to the large bowl with the pasta. Pour the dressing over and gently mix. It may look a little soupy, don’t worry, the pasta soaks up the dressing as it chills.
Chill and Serve: Cover and refrigerate for at least 1 hour. Stir once halfway through chilling. Serve cold and enjoy!
