Ingredients

• 10 pounds (4.5 kg) of rotini or penne pasta
• 4 quarts (3.8 liters) of cherry tomatoes, halved
• 2 large cucumbers, diced
• 4 cups (480 g) of black olives, sliced
• 4 cups (480 g) of shredded mozzarella cheese
• 2 cups (300 g) of red onion, finely chopped
• 2 cups (480 ml) of Italian dressing (store-bought or homemade)
• 1 cup (240 ml) of olive oil
• 1/2 cup (120 ml) of red wine vinegar
• 2 tablespoons of dried oregano
• 2 tablespoons of dried basil
• Salt and freshly ground black pepper to taste

Instructions

1. Bring a large commercial-sized stockpot or multiple large pots of water to a rolling boil. Add a generous amount of salt (about 1-2 tablespoons per 4 quarts of water) for flavor. Cook the pasta until al dente according to package instructions, approximately 10-12 minutes. Drain well and rinse with cold water to stop the cooking process. Spread the pasta on large baking sheets or clean surfaces to cool quickly and prevent sticking.
2. While the pasta cools, prepare the dressing. In a large mixing bowl, whisk together the Italian dressing, olive oil, red wine vinegar, dried oregano, dried basil, salt, and pepper. Adjust seasoning to taste. This dressing will serve as the base for the salad, providing flavor and moisture.
3. In a very large mixing container or multiple large bowls, combine the cooled pasta with the cherry tomatoes, diced cucumbers, sliced olives, shredded mozzarella, and chopped red onion. Pour the prepared dressing evenly over the mixture. Toss gently but thoroughly to ensure all ingredients are coated with the dressing.
4. Cover the salad tightly with plastic wrap or transfer it to airtight containers. Refrigerate for at least 2 hours, preferably 4 hours, to allow flavors to meld. This make-ahead step improves the taste and makes serving easier.
5. Before serving, give the salad a gentle toss to redistribute the dressing. Taste and adjust seasoning if necessary, adding more salt, pepper, or vinegar as desired. Serve in large bowls or trays, garnished with additional herbs if desired.

Tips

• Substitutions: Feel free to swap in other vegetables like bell peppers or artichoke hearts. For a protein boost, add cooked chicken, ham, or chickpeas.
• Storage: Keep the salad refrigerated in airtight containers for up to 24 hours. Avoid mixing in fresh herbs or delicate ingredients until just before serving to maintain freshness.
• Common mistakes: Overcooking the pasta can make it mushy. Always cook al dente and rinse thoroughly with cold water. Also, adding too much dressing too early can make the salad soggy; dress just before serving if possible.
• Batch preparation: Prepare the pasta and dressing in separate large containers and combine just before serving for maximum freshness and texture.

Serving Suggestions

This pasta salad is ideal served chilled or at room temperature, making it perfect for outdoor picnics, buffet tables, or potlucks. Pair it with grilled meats, fresh bread, or a green salad for a complete meal. Garnish with fresh basil or parsley for added color and flavor.

Variations

Customize this pasta salad to suit your preferences or dietary needs. Add cooked shrimp or tuna for seafood lovers, or incorporate roasted vegetables for a smoky flavor. You can also change the dressing to a vinaigrette with lemon juice for a tangier profile or use a creamy Italian or ranch dressing for a richer taste. For a gluten-free version, substitute gluten-free pasta and ensure all ingredients are gluten-free.

Storage and Reheating

Store the pasta salad in airtight containers in the refrigerator for up to 24 hours. Because it’s a cold dish, reheating isn’t necessary. If you prefer serving it at room temperature, take it out about 30 minutes before serving. The flavors will deepen over time, but avoid leaving it out at room temperature for more than 2 hours to prevent spoilage.

Frequently Asked Questions

Can I prepare this pasta salad ahead of time?

Yes, preparing the pasta and dressing separately and combining them a few hours before serving yields the best flavor. It’s recommended to refrigerate for at least 2-4 hours to allow flavors to meld.

How do I keep the pasta from sticking together?

Rinse the cooked pasta thoroughly with cold water immediately after draining to stop the cooking process and remove excess starch. Tossing it with a little olive oil before combining with other ingredients can also help prevent sticking.

What are some good substitutions for the ingredients?

You can substitute cherry tomatoes with sun-dried tomatoes, cucumbers with bell peppers, black olives with green olives, and mozzarella with feta cheese. Adjust based on your preferences and dietary restrictions.

How long can I store leftovers?

Leftover pasta salad can be kept in the refrigerator for up to 24 hours. For best quality and safety, consume within this timeframe and store in airtight containers.

Can I make this vegan or vegetarian?

Yes, simply omit the cheese or replace it with a vegan cheese alternative. Use a vegan or dairy-free dressing, and add more vegetables or plant-based proteins like chickpeas or tofu to enhance the dish.

Is this suitable for gluten-free diets?

Absolutely. Use gluten-free pasta and verify that all other ingredients, especially dressings and add-ins, are certified gluten-free to ensure the dish meets dietary needs.
