- 3 tablespoons red wine vinegar
- 1 tablespoon lemon juice

Ingredient Notes & Substitutions
Pasta: Penne holds dressing well because of its ridges and hollow center, but rotini, farfalle, or fusilli work as substitutes. For a gluten-free version, use a gluten-free penne and cook it slightly under the package time, since it softens further as it cools.
Cheese: Mozzarella pearls add a mild, creamy bite. Feta or provolone are good alternatives if you prefer a sharper flavor. Leave the cheese out entirely for a dairy-free version.
Vegetables: This recipe is flexible. Zucchini, artichoke hearts, or roasted red peppers all work well in place of or alongside the vegetables listed.
Dressing: A store-bought Italian dressing can replace the homemade version if you’re short on time. Look for one without excessive added sugar for the best flavor balance.
Protein additions: Grilled chicken, salami, pepperoni, or chickpeas turn this side dish into a more substantial main course.
Step-by-Step Instructions
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Add the penne and cook according to the package directions until al dente. Drain the pasta and rinse briefly under cold water to stop the cooking process and cool it down.
Step 2: Make the Dressing
In a small bowl or jar, whisk together the olive oil, red wine vinegar, lemon juice, Dijon mustard, oregano, garlic powder, salt, pepper, and sugar (if using). Whisk or shake until fully combined.
Step 3: Prep the Vegetables
While the pasta cooks and cools, dice the cucumber, onion, and bell pepper, halve the cherry tomatoes, and slice the olives.
Step 4: Combine
In a large mixing bowl, combine the cooled pasta, tomatoes, cucumber, red onion, bell pepper, olives, mozzarella, and parsley.
Step 5: Dress and Toss
Pour the Italian dressing over the pasta salad and toss until everything is evenly coated. Sprinkle with grated Parmesan and toss once more.
Step 6: Chill and Serve
Cover and refrigerate for at least 30 minutes before serving to let the flavors meld. Give the salad a final toss before serving, since the dressing tends to settle at the bottom.
Expert Tips & Common Mistakes
- Don’t overcook the pasta. Al dente pasta holds its shape better in a cold salad. Overcooked penne turns mushy after sitting in dressing.
- Rinse the pasta after cooking. This is one case where rinsing is helpful, since it stops the cooking process and prevents the pasta from clumping.
- Dress the pasta while slightly warm, but not hot. Warm pasta absorbs dressing more effectively, resulting in better flavor throughout.
- Salt the pasta water generously. This is your main chance to season the pasta itself, since the salad is served cold.
- Let it chill. Skipping the resting time results in a salad that tastes like separate ingredients rather than a cohesive dish.
- Refresh before serving. If the salad sits overnight, the pasta absorbs much of the dressing. A small drizzle of olive oil and vinegar before serving brings it back to life.
Variations
Greek-Style Penne Pasta Salad: Swap mozzarella for feta, add kalamata olives, and mix in diced cucumber and red onion with a lemon-oregano dressing.
Caprese Penne Pasta Salad: Use fresh mozzarella, cherry tomatoes, and fresh basil with a balsamic glaze drizzle.
Protein-Packed Pasta Salad: Add grilled chicken breast, chickpeas, or diced salami for a heartier, main-dish version.
Pesto Penne Pasta Salad: Replace the Italian dressing with basil pesto thinned slightly with olive oil and lemon juice.
Spicy Penne Pasta Salad: Add diced pepperoncini and a pinch of red pepper flakes to the dressing for extra heat.
Serving Suggestions
Penne pasta salad pairs naturally with grilled foods like burgers, chicken, or bratwurst, making it a reliable barbecue side. It also works well alongside sandwiches, fried chicken, or as part of a larger buffet spread for potlucks and picnics. For a light lunch, serve a generous portion on its own with a piece of crusty bread.
Storage & Reheating
Refrigerator: Store the pasta salad in an airtight container in the refrigerator for up to 4 days. The flavor typically improves after the first few hours as the dressing fully absorbs.
Freezing: This salad is not recommended for freezing, since the vegetables and pasta texture break down significantly after thawing.
Reheating: This is a cold salad and is not meant to be reheated. If the pasta has absorbed most of the dressing after a day or two in the fridge, refresh it with a small amount of olive oil, vinegar, and a pinch of salt before serving.
