This is a cold pasta salad built around penne, five fresh vegetables, and a sharp lemon dressing that comes together in 30 minutes. There’s no cream, no mayo, and no cooking beyond boiling pasta and blanching broccoli. It’s the kind of thing you can make on a Tuesday and still be eating well by Thursday.
What makes this version work
Two things actually matter here. First, rinsing the pasta under cold water after draining isn’t just about cooling it down — it stops the cooking immediately and washes off surface starch, which would otherwise make the noodles clump and turn gummy as the salad sits. Second, the dressing is whisked, not just stirred. Olive oil and lemon juice don’t naturally stay combined, but adding Dijon mustard gives the emulsion something to hold onto. Whisk until the dressing looks slightly thick and uniform — that coating is what makes every bite taste like the dressing, not just the pieces that happen to sit in a puddle of it.
Leftovers and make-ahead
This salad keeps well in the fridge for up to 3 days in a sealed container. The pasta will absorb some of the dressing as it sits, so if you’re making it ahead, hold back about a third of the dressing and toss it in right before serving. The cherry tomatoes soften slightly by day two, which is fine — they’re still good. Don’t freeze this one; the vegetables go watery and the pasta texture doesn’t recover. If you want to prep components separately, the dressing can be made up to 5 days ahead and stored in a jar in the fridge — just shake it before using.
Common problems and fixes
- Dressing tastes flat or oily: The lemon juice and salt are doing the heavy lifting here. Taste the dressing before you pour it — if it tastes dull, add a small squeeze more lemon juice and a pinch of salt, then whisk again. Garlic that’s been sitting too long also loses punch, so use a fresh clove.
- Zucchini turns soggy: Slice it thin but don’t add it to the salad more than a couple of hours before serving. Zucchini releases water once it contacts the acidic dressing, so the longer it sits, the softer it gets. Skip the garnish of extra raw zucchini on top — not worth the extra prep.
- Pasta clumps together after rinsing: This usually means it wasn’t rinsed long enough, or it sat in the colander too long before being tossed. Rinse thoroughly until the pasta feels cool to the touch, then move it into the mixing bowl right away and toss with a small drizzle of olive oil if you’re not dressing it immediately.
- Broccoli turns yellow or mushy: The ice bath step is what keeps it bright green and crisp. If you skip it, the broccoli keeps cooking from residual heat. A bowl of cold tap water works if you don’t have ice — just make sure it’s genuinely cold and that you move the broccoli in quickly after the one-minute boil.
- Salad tastes bland after chilling: Cold dulls salt and acid. Always taste again after the salad has been in the fridge, and adjust with a little more lemon juice or a pinch of salt before serving. This is normal and not a mistake in the original seasoning.

For the Pasta Salad:
- 12 oz penne pasta or any short pasta variety

- 1 tbsp fresh parsley chopped
Instructions
- Cook the pasta according to package instructions in salted boiling water until al dente (about 8-10 minutes). Drain and rinse under cold water to stop the cooking process.
- While the pasta cooks, blanch the broccoli in boiling water for 1 minute, then transfer to an ice bath to retain its bright color and crisp texture.
- In a mixing bowl, whisk together the olive oil, lemon juice, lemon zest, minced garlic, Dijon mustard, salt, and black pepper until emulsified.
- Add the cooked pasta, blanched broccoli, cherry tomatoes, sliced zucchini, red bell pepper, and red onion to a large mixing bowl.
- Pour the lemon herb dressing over the salad and toss gently to combine. Add the chopped basil and parsley for a fresh burst of flavor.
- Let the salad sit for 10 minutes to allow flavors to meld before serving. Serve chilled or at room temperature.
Notes
- For an extra protein boost, add grilled chicken, shrimp, or chickpeas.
- Swap parsley for mint for a different herbaceous twist.

Frequently asked questions
Can I use a different pasta shape?
Yes — any short pasta works well here. Rotini, farfalle, and fusilli all hold the dressing in their ridges or folds, which can actually give you better coverage than smooth penne.
Do I have to blanch the broccoli, or can I use it raw?
You can use it raw if you prefer more crunch. Blanching for one minute just takes the raw edge off and makes it easier to chew, especially for kids — but it’s not required.
I don’t have fresh basil or parsley. Can I use dried herbs?
Dried herbs will work in a pinch, but use about a third of the amount since they’re more concentrated. Add them directly to the dressing rather than sprinkling on top, so they have time to hydrate and blend in.
How do I know if the pasta is actually al dente and not undercooked?
Bite a piece — it should feel firm in the center but not chalky or hard. Most penne takes 8 to 10 minutes, but start checking at 7 since you’ll be rinsing it in cold water, which stops any further cooking.
Can I make this salad without olive oil?
A neutral oil like avocado oil or light vegetable oil will work. The flavor will be milder since olive oil has its own taste, but the dressing will still emulsify and coat the pasta properly.
Is this salad okay to bring to a cookout and leave out for a while?
It’s fine at room temperature for up to two hours. After that, the vegetables start to break down and food safety becomes a concern, so keep it in a cooler if you’re outside on a hot day.
