Ingredient List

For the Pasta Salad

• 12 oz (340g) pasta (rotini, fusilli, or bowtie)
• 1 ½ cups sweet corn (fresh, canned, or frozen)
• 1 ½ cups cherry tomatoes, halved
• 2 medium zucchini, sliced into half-moons
• ¼ cup red onion, finely sliced
• ¼ cup fresh basil, chopped
• ¼ cup grated parmesan cheese (optional)

For the Dressing

• ¼ cup olive oil
• 2 tablespoons lemon juice (freshly squeezed)
• 1 tablespoon red wine vinegar
• 2 cloves garlic, minced
• 1 teaspoon Dijon mustard
• ½ teaspoon salt (or to taste)
• ¼ teaspoon black pepper

Ingredient Notes

• Pasta: Short pasta shapes like rotini or fusilli work best because they complement the dressing really well. I always go for something with ridges—it makes every bite more flavorful.
• Corn: Fresh corn cut off the cob gives the sweetest flavor, especially in peak season. Frozen works great too—just thaw it first. Don’t skip the corn! It adds that juicy pop that makes this dish stand out.
• Cherry tomatoes: Go for ripe, firm ones. I like using a mix of red and yellow for extra color—it makes the salad look even more vibrant.
• Zucchini: Slice it thin so it blends nicely with the pasta. If you prefer a softer texture, you can lightly sauté it, but raw keeps things fresh and crisp.
• Olive oil: Use a good-quality extra virgin olive oil here—it’s the base of the dressing, so it really affects the overall taste.
• Lemon juice: Freshly squeezed is best. It brightens everything and balances the sweetness from the corn and tomatoes.
• Dijon mustard: Just a small amount helps emulsify the dressing and adds a subtle tang. Don’t skip it—it makes the dressing taste more complete.
• Parmesan cheese: Totally optional, but it adds a nice salty, savory finish. I always include it when I want a slightly richer flavor.

Kitchen Equipment Needed

• Large pot: For boiling the pasta evenly. A deep pot gives the pasta room to cook without sticking.
• Colander: For draining the pasta quickly. I prefer one with sturdy handles for easy shaking.
• Large mixing bowl: To toss everything together without spilling. Go bigger than you think—you’ll need the space.
• Sharp knife: For slicing zucchini and halving cherry tomatoes cleanly. A good knife makes prep much faster.
• Cutting board: A stable surface for chopping all your vegetables safely.
• Small bowl or jar: For mixing the dressing. I like using a jar with a lid so I can just shake it—super quick and mess-free.
• Whisk or fork: To blend the dressing ingredients smoothly if you’re not using a jar.
• Measuring cups and spoons: For getting the dressing ratios just right.
• Tongs or large spoon: For tossing the pasta salad evenly so everything gets coated in the dressing.

Instructions

1. Cook the Pasta

• Bring a large pot of salted water to a boil.
• Add the pasta and cook according to package instructions until al dente (tender but still slightly firm).
• Stir occasionally to prevent sticking.
• Drain the pasta using a colander and rinse briefly under cool water to stop the cooking process.
• Let it drain completely and set aside to cool.

Pro tip: Don’t overcook the pasta—it should hold its shape so it doesn’t turn mushy when mixed with the dressing.

2. Prepare the Vegetables

• Slice the zucchini into thin half-moons.
• Halve the cherry tomatoes.
• Thinly slice the red onion.
• If using fresh corn, cut the kernels off the cob. If using frozen, make sure it’s fully thawed and drained.

Pro tip: Slice the zucchini thinly for the best texture—it blends better with the pasta and absorbs more flavor.

3. Make the Dressing

• In a small bowl or jar, add olive oil, lemon juice, red wine vinegar, minced garlic, Dijon mustard, salt, and black pepper.
• Whisk everything together until well combined, or seal the jar and shake until smooth.

Pro tip: Shake or whisk thoroughly so the oil and lemon juice fully combine—this keeps the dressing from separating later.

4. Combine Everything

• Add the cooled pasta to a large mixing bowl.
• Add the corn, cherry tomatoes, zucchini, and red onion.
• Pour the dressing over the mixture.
• Toss gently using tongs or a large spoon until everything is evenly coated.

5. Add Finishing Touches

• Sprinkle in the chopped fresh basil and grated parmesan cheese (if using).
• Toss lightly again to distribute evenly.

6. Chill and Serve

• Cover the bowl and refrigerate for at least 30 minutes to let the flavors come together.
• Give it a quick toss before serving.

Pro tip: Letting the salad chill makes a big difference—the pasta absorbs the dressing, and the flavors become more balanced and rich.

Tips and Tricks for Success

• Salt your pasta water properly: The pasta itself needs seasoning from the start. It should taste slightly salty like seawater for the best flavor.
• Cool the pasta before mixing: Adding hot pasta can make the vegetables wilt and absorb too much dressing too quickly.
• Don’t skip the resting time: Letting the salad sit in the fridge allows the flavors to blend and deepen, making a noticeable difference.
• Toss again before serving: The dressing can settle at the bottom, so a quick mix brings everything back together.
• Cut ingredients evenly: Keeping the zucchini, tomatoes, and onion similar in size ensures a balanced bite every time.
• Adjust seasoning at the end: After chilling, taste and add a little extra salt, pepper, or lemon juice if needed.
• Use fresh herbs last: Adding basil right before serving keeps it vibrant and prevents it from wilting.

Ingredient Substitutions and Variations

• Swap the pasta: Use whole wheat, gluten-free, or even chickpea pasta for a different texture and added nutrients.
• Try different vegetables: Add cucumbers, bell peppers, or avocado for extra color and crunch.
• Use grilled zucchini: Lightly grilling the zucchini adds a smoky flavor that pairs really well with the corn.
• Change the cheese: Replace parmesan with feta, mozzarella pearls, or skip it entirely for a dairy-free option.
• Add protein: Toss in grilled chicken, shrimp, tuna, or chickpeas to turn it into a more filling meal.
• Switch up the dressing: Use a balsamic vinaigrette or a light creamy dressing if you want a different flavor profile.
• Make it spicy: Add red pepper flakes or a pinch of cayenne for a little heat.
• Herb variations: Swap basil with parsley, cilantro, or a mix of fresh herbs depending on what you have available.

Serving Suggestions

• As a light main dish: Serve a generous bowl on its own for lunch or dinner—it’s filling without feeling heavy and works perfectly on warm days.
• With grilled proteins: Pair it with grilled chicken, shrimp, or steak for a more complete meal. The fresh flavors balance smoky, charred meats really well.
• Alongside classic barbecue dishes: It makes a great side for burgers, grilled fish, or BBQ chicken, adding a fresh contrast to richer foods.
• With simple sides: I love serving this pasta with garlic bread and a crisp green salad—it balances the textures perfectly and makes the meal feel complete.
• For gatherings and picnics: Serve it chilled or at room temperature at potlucks or outdoor meals—it holds up well and stays delicious for hours.

Storage and Reheating Instructions

• Refrigerate properly: Store in an airtight container in the fridge for up to 3–4 days.
• Stir before serving: The dressing may settle, so give it a good toss to redistribute the flavors.
• Refresh if needed: Add a splash of olive oil or a squeeze of lemon juice before serving to bring it back to life.
• Keep it chilled: For best taste and texture, serve straight from the fridge or slightly cooled.
• Avoid reheating: This pasta salad is meant to be enjoyed cold or at room temperature—heating can make the vegetables soft and less fresh.

Frequently Asked Questions

Can I make this pasta salad ahead of time?

Yes! This salad actually tastes better after a few hours in the fridge. Making it ahead gives the flavors time to blend beautifully.

Can I use frozen or canned corn?

No, you can use it raw for a fresh, slightly crisp texture. If you prefer it softer, lightly sauté or grill it before adding.

What type of pasta works best?

Short pasta like rotini, fusilli, or bowtie is ideal because it holds the dressing well and mixes easily with the other ingredients.

How do I keep the salad from drying out?

If it starts to look a bit dry after chilling, just add a drizzle of olive oil or a squeeze of lemon juice and toss—it will freshen it right up.

Can I make this dairy-free?

Yes, simply skip the parmesan or replace it with a dairy-free alternative. The salad still tastes fresh and flavorful without it.
