Ingredients (Serves 100)
- 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, cut in half
- 3 green bell peppers, diced
- 3 red bell peppers, diced
- 36 ounces sliced black olives, drained
Step-by-Step Instructions
Step 1: Cook the Pasta
Cook half the pasta in a large pot of salted boiling water. Be sure to cook it just until al dente, as it will soften a little more after being tossed with dressing and chilled. Drain well, then rinse quickly under cold water to stop the cooking and cool it down.
Step 2: Start Building the Salad
In a very large bowl, place half of the cooled pasta. Pour in half of the Italian dressing, sprinkle with salt and pepper, and stir with a long-handled spoon to coat. This ensures every piece of pasta gets a flavorful start.
Step 3: Add the Veggies & Cheese
Toss in the diced bell peppers, cherry tomatoes, mozzarella cubes, and sliced olives. The vegetables bring freshness and crunch, while the cheese adds richness and a satisfying bite. Stir everything thoroughly so the ingredients are well distributed.
Step 4: Finish & Chill
Pour the salad into two or more large foil pans or containers. Cover tightly with foil or plastic wrap and refrigerate for at least 4 hours before serving. This chilling time allows the flavors to blend and the pasta to soak up the dressing.
Tips for Making Pasta Salad for a Large Group
- Don’t Overcook the Pasta: Slightly firm pasta holds up better after chilling.
- Dress in Stages: Coat the pasta with dressing while it’s still warm, then add more after chilling if needed.
- Keep it Colorful: Use a variety of vegetables—zucchini, cucumbers, or red onions also work beautifully.
- Cheese Alternatives: Swap mozzarella with cheddar, feta, or provolone for different flavor profiles.
- Storage: Keep refrigerated until serving. It stays fresh for up to 3 days.

This recipe is endlessly adaptable. Try these twists to suit different occasions or dietary needs:
- Greek Pasta Salad: Replace Italian dressing with a Greek vinaigrette and use feta cheese, cucumbers, and kalamata olives.
- Tex-Mex Style: Add black beans, corn, jalapeños, and cheddar cheese with a cilantro-lime dressing.
