Bright colors, fresh flavors, and satisfying textures—here's what makes this crowd-pleasing pasta salad shine.
| Ingredient | Amount | Notes |

| Cherry Tomatoes 🍅 | 1 pint | Halved for freshness |
| Fresh Basil Leaves 🌿 | ½ cup | Packed, stems removed |

| Red Onion 🧅 | 1 medium | Thinly sliced |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For vinaigrette |
| Garlic Cloves 🧄 | 4 cloves | Minced for vinaigrette |

The tri-color rotini is a game-changer—look for Barilla or De Cecco for that perfect al dente bite. Whole Foods or Trader Joe's usually carry the best quality. The key is cooking it just shy of al dente, then shocking it in ice water to lock in that crisp texture. For the vinaigrette, Whole Foods has the best selection of fresh herbs—basil and parsley should be vibrant green, not wilted. The red wine vinegar? Bartles & Jaymes is my go-to for consistency, but any decent brand works. The bell peppers should be firm and shiny; Trader Joe's often has the best organic selection at a great price.
No tri-color pasta? Regular rotini or penne works in a pinch—just toss in a handful of dyed pasta for color if you're feeling fancy. Fresh herbs wilt fast, so if you're prepping ahead, dried basil or parsley at half the amount keeps things flavorful. The cherry tomatoes can be swapped for grape tomatoes if you prefer. For the vinaigrette, apple cider vinegar gives a nice twist if you're out of red wine vinegar. The garlic? Fresh is non-negotiable—jarred garlic has no soul. And if you're watching calories, reduce the olive oil by 2 tbsp without sacrificing flavor.
This pasta salad tastes even better the next day—flavors meld beautifully overnight, making it perfect for meal prep. Store in an airtight container in the fridge for up to 5 days, though the herbs will start to lose their pop after 3 days. For longer storage, freeze the vinaigrette separately—it keeps for 3 months and you can just toss it with fresh pasta and veggies when ready. The vegetables stay crisp for 2-3 days if you keep them dry; pat them thoroughly before adding to the salad.

Step-by-step instructions for ashley Mac's pasta salad
Here's how to create this vibrant, herb-packed pasta salad that stays fresh and delicious all day.
Cook and Chill the Tri-Color Rotini
Bring a large pot of water to a rolling boil and add 1.5 lbs of the tri-color rotini pasta. Cook until al dente—about 1 minute less than the package instructions suggest. This ensures the pasta stays perfect even after chilling.
Drain the pasta immediately and transfer it to a large bowl. While still warm, pour in 2 quarts of ice water and let it sit for 5 minutes. This shocking process stops the cooking and prevents the pasta from becoming mushy. Drain again thoroughly and set aside—it's ready for the herbed vinaigrette.
Prepare the Herbed Vinaigrette
In a medium bowl, whisk together 0.5 cup extra-virgin olive oil, 0.5 cup red wine vinegar, 2 tbsp Dijon mustard, 2 tbsp freshly squeezed lemon juice, 1.5 tsp salt, and 1 tsp freshly ground black pepper. This forms the base of our bright, tangy dressing.
Next, add the 4 minced garlic cloves, 0.5 cup packed fresh basil leaves, and 0.25 cup chopped fresh parsley leaves to the bowl. Stir gently to combine—you want the herbs to infuse the dressing without becoming pulpy. Taste and adjust seasoning if needed, then set aside.
Prep and Combine All Vegetables
Peel and dice the 1.5 lbs English cucumber into ½-inch cubes, removing any seeds if present. Dice the 2 medium bell peppers into small, even pieces—this ensures they cook evenly in the dressing. Halve the 1 pint cherry tomatoes and thinly slice the 1 medium red onion.
Add all the prepared vegetables to the chilled pasta. Pour the herbed vinaigrette over the top and gently toss everything together with a large spoon or your hands. The cold pasta helps prevent the vegetables from bruising during mixing.
Chill and Serve
Cover the bowl with plastic wrap and refrigerate for at least 2 hours, or up to 8 hours. This chilling time allows all the flavors to meld together beautifully. The pasta will absorb the vinaigrette perfectly, creating a cohesive salad with vibrant colors and fresh flavors.
Before serving, give the salad one final toss to redistribute the dressing evenly. The tri-color rotini will look stunning against the bright vegetables, and the herbed vinaigrette will give it a refreshing, tangy kick. This pasta salad is perfect for picnics, potlucks, or as a light summer meal.
Pro Tips For Making Ashley Mac'S Pasta Salad
- RINSE PASTA COOL: Tri-color rotini sticks to everything when hot—drain it, then rinse under cold water for 30 seconds. I learned this the hard way after watching my first batch turn into a gluey mess. The pasta will cool faster too, so you’re not waiting forever for the dressing to cling.
- PEEL CUCUMBERS FAST: Skip the peeler—use a spoon to scoop out the seeds and thin the skin in one motion. English cucumbers have thick skin that’s tough to peel strip-by-strip, and this saves your hands from turning into prunes. Toss the peeled halves directly into ice water to keep them crisp.
- DRESSING FIRST, NOT LAST: Mix the red wine vinegar and Dijon mustard before adding the pasta—let it sit for 5 minutes while you prep veggies. I used to toss everything together at the end, and the dressing always ended up uneven. This gives the mustard time to mellow out and the vinegar to bloom, so the flavors marry properly.
- CHOP PEPPERS SMALL: Dice bell peppers into ¼-inch cubes, not slices—small pieces distribute flavor and soften faster in the dressing. I was skeptical until I tried it; now I double-check because uneven peppers make the salad look (and taste) amateur. A chef’s knife works, but a food processor gives consistent results in 10 seconds.
Common mistakes when making great ashley mac's pasta salad
Overcooking the Pasta
The biggest mistake I see is cooking the pasta all the way to al dente and then letting it continue cooking in the dressing. The tri-color rotini should be cooked 1 minute less than package instructions suggest, then shocked in ice water to stop the cooking process completely.
I've seen salads turn mushy when people skip this step—trust me, the texture difference is night and day. 🥗
Skipping the Ice Water Shock
Many recipes mention shocking pasta in ice water, but people often overlook this crucial step. Pouring 2 quarts of ice water over the warm pasta for 5 minutes prevents overcooking and keeps the strands firm.
Without this, your salad will have that sad, limp texture that no one wants. I learned this the hard way after making a batch that sat too long in warm dressing.
Using Wilted Herbs
Fresh herbs are the soul of this pasta salad, but they lose their vibrancy quickly. If your basil or parsley looks even slightly wilted, toss it and grab fresh from the store—I recommend Whole Foods or Trader Joe's for the best quality.
The dressing needs bright, aromatic herbs to shine. A pro trick? Add the herbs right before serving to keep their freshness intact. 🌿
Uneven Vegetable Prep
Chopping vegetables into inconsistent sizes leads to uneven textures in your salad. Dice the bell peppers and cucumber into ½-inch cubes and slice the red onion uniformly. This ensures everything cooks evenly in the dressing and creates a satisfying bite in every forkful.
I've seen salads where soft veggies and crunchy veggies fight for space—don't let that happen!
Not Chilling Long Enough
Rushing to serve this salad straight after mixing is a mistake. The flavors need time to meld together during the 2-8 hour chilling period in the fridge. This is when the vinaigrette really clings to the pasta and the vegetables absorb the flavors.
I always make mine the night before—it tastes so much better after resting. ⏰
Overmixing the Dressing
When combining the dressing, many people overmix it, turning the fresh herbs into a pulpy mess. Stir gently just until everything is coated—you want the herbs to infuse the dressing without losing their texture.
I like to use a large spoon or even my hands to toss everything lightly. The goal is a harmonious blend, not a smoothie. 💫

Frequently asked questions about ashley Mac's pasta salad
Can I make this pasta salad ahead of time?
This salad tastes even better when made 1-2 days ahead—the flavors meld beautifully in the fridge. Store it in an airtight container for up to 5 days, though the herbs stay freshest for 3 days. For longer prep, make the vinaigrette separately and store it for 3 months in the freezer.
What if I don't have tri-color pasta?
No problem! Use regular rotini or penne instead. For extra color, toss in 1 tbsp of food coloring (like gel pasta dye) to the cooking water or add a handful of dyed pasta (like red or green). The texture will still be perfect—just the visual appeal changes slightly.
How do I keep the vegetables crisp?
Pat all vegetables completely dry with paper towels before adding them to the salad. Also, avoid overmixing after adding the dressing—just toss gently. For extra crunch, add cherry tomatoes and cucumbers right before serving (they soften fastest). The key is timing and moisture control!
Can I make this pasta salad without fresh herbs?
Yes, but the flavor will be less vibrant. Use 1 tbsp dried basil and 1 tbsp dried parsley (half the fresh amount) and add them to the vinaigrette. For best results, toast the dried herbs in a dry pan for 30 seconds until fragrant before mixing. Fresh herbs are ideal, but this works in a pinch!
Is this pasta salad gluten-free?
Not as written—regular rotini contains gluten. For a gluten-free version, swap the pasta for gluten-free rotini (like Barilla GF or Jovial) and use gluten-free Dijon mustard. All other ingredients are naturally gluten-free. Double-check labels to ensure no cross-contamination.
