Begin by boiling a large pot of salted water over high heat. Once boiling, add in the rotini pasta and cook according to the package instructions until al dente, usually around 8-10 minutes. Drain the pasta in a colander and rinse it under cold water, stopping the cooking process and cooling it down for the salad.

While the pasta cools, prepare the other ingredients for your Dill Pickle Pasta Salad. Cube the sharp cheddar cheese into bite-sized pieces, slice the mini dill pickles into rounds, and finely chop the red onion. Ensure all ingredients are prepped and ready to combine for that delicious, creamy mix!

In a medium-sized mixing bowl, whisk together the mayonnaise, sour cream, dill pickle juice, fresh dill, salt, and pepper. This creamy dressing is key to the flavor of your Dill Pickle Pasta Salad, so make sure to blend it thoroughly until it's smooth and well combined. Taste and adjust seasonings if necessary for the perfect tang.

In a large mixing bowl, combine the cooled rotini pasta, cubed cheddar cheese, sliced pickles, and chopped red onion. Pour the creamy dressing over the top, then gently toss all the ingredients together until everything is evenly coated.

Cover the bowl with plastic wrap or transfer the Dill Pickle Pasta Salad to an airtight container. Refrigerate for a minimum of 2 hours to allow the flavors to meld beautifully.

After the salad has chilled, give it a good stir before serving. If the salad seems a bit dry, consider stirring in a splash of extra dill pickle juice or a dollop of mayonnaise. This creamy, tangy Dill Pickle Pasta Salad is now ready to be enjoyed alongside your favorite grilled meats or at your next potluck!
