Cook the Pasta: Bring a large pot of salted water to a boil. Cook the rotini pasta according to package directions until al dente. Drain and rinse with cold water.
16 oz rotini pasta
Soak the Pasta in Pickle Juice: Transfer the drained pasta to a mixing bowl and pour ⅓ cup of pickle juice over it. Stir and let it sit while you prep the rest of the ingredients.
⅓ cup dill pickle juice
Chop the Ingredients: Dice the baby dill pickles and Colby Jack cheese into small cubes. Finely chop the white onion.
2 cups baby dill pickles, 8 oz Colby Jack cheese, 1 small white onion
Drain Excess Pickle Juice: After the pasta has soaked, drain any excess liquid before adding the other ingredients.
Mix the Salad: Add the chopped pickles, cheese, and onion to the pasta. Stir to combine.
Make the Dressing: In a small bowl, whisk together the mayonnaise, sour cream, pickle juice, dill, salt, and black pepper until smooth.
1 cup mayonnaise, ½ cup sour cream, ⅓ cup dill pickle juice
Combine Everything: Pour the dressing over the pasta salad and stir until everything is evenly coated.
Chill or Serve: Serve immediately for a slightly warm pasta salad or cover and refrigerate for 1-2 hours for a chilled version. If the dressing thickens too much in the fridge, stir in a little extra pickle juice before serving.
