Ingredients

  • 4 pounds multi-colored rotini pasta
  • 64 ounces Italian dressing
  • 2 teaspoons kosher salt
  • 1 teaspoon black pepper
  • 32 ounces mozzarella cheese cut into small cubes
  • 40 ounces cherry tomatoes halved
  • 3 green bell peppers diced
  • 3 red bell peppers diced
  • 36 ounces sliced black olives drained

Instructions

Cook the Pasta:

  • Cook half of the rotini pasta according to package instructions. Drain and rinse with cold water to stop the cooking process.
  • Repeat with the second half of the pasta.

Mix the Salad:

  • In a very large bowl, place half of the cooked pasta.
  • Pour half of the Italian dressing over the pasta and sprinkle with 1 teaspoon of kosher salt and ½ teaspoon of black pepper. Stir well.
  • Add half of the mozzarella cheese, cherry tomatoes, bell peppers, and black olives. Stir to combine.
  • Repeat the process with the remaining pasta, dressing, salt, pepper, and other ingredients. Stir everything together thoroughly.

Store the Salad:

  • Divide the pasta salad into 2 or more large foil pans for easier storage. Cover tightly with foil or plastic wrap and refrigerate until ready to serve.

Chill and Serve:

  • For best results, refrigerate the pasta salad for at least 4 hours, preferably 24 hours, to allow the flavors to meld.
  • Before serving, check if the pasta salad is dry. If needed, add extra Italian dressing to refresh it. Serve chilled.
  • Notes
  • Mixing Tip: Working with half a batch at a time makes it easier to combine ingredients evenly.
  • Make-Ahead: Preparing the salad a day in advance enhances the flavor.
  • Extra Dressing: Keep an additional bottle of Italian dressing on hand to add if the salad dries out before serving.
