How do you make a Vegetarian Pasta Salad so fabulous that even this self confessed carnivore can’t get enough of it? MARINATE the vegetables! This big, fat pasta salad recipe is a standout – it’s juicy, it’s flavour loaded and it looks as amazing as it tastes! Excellent summer food that lasts for days.
Vegetarian Pasta Salad
Who would’ve thought those random veggies you’ve got left in the bottom of your fridge could be transformed into something as incredible as this Vegetarian Pasta Salad??
Forget limp, bland veggies sitting sadly amongst tasteless, soggy pasta. THIS cold pasta salad is the polar opposite of that. It’s vibrant, it’s flavour loaded, it’s JUICY, and will make even green-haters scoff down a weeks’ worth of veggies in one sitting!
Marinating the vegetables for just 30 minutes makes all the difference in this pasta salad!
How to make this summer Vegetable Pasta Salad
Cook veggies (BBQ or oven) -> marinade in dressing -> toss through pasta.
Yep. That’s it.
(OK I might’ve skipped a few steps like chop / oil / salt ‘n pepper the veggies, but you get the gist!)
Pro tip – how to keep your pasta salad JUICY (without using tons of oil)
Pasta salads keep well for days upon days, but the pasta tends to suck up all the dressing and vegetable juices. So to keep this nice and juicy if serving this 2, 3 or even 4 days later, the trick is to shake up the dressing with some pasta cooking water to make more dressing without using copious amounts of oil.
This is what happens: pasta cooking water is starchy from the pasta. The starch emulsifies with the oil in the dressing and thickens the pasta cooking water so it’s the consistency of dressing. You have more dressing (with the same amount of flavour in it) so you can reserve some to make the pasta salad nice and juicy when you serve it up the next day….and the next!
Vegetables for pasta salad
The beauty of this Vegetarian Pasta Salad recipe is this – there are no rules. You can literally put any roastable/grillable veggie in this – and it’s going to be amazing.
Oh wait. That was a grand statement that sounded really good but I realised was a bit untrue. I think potato might be a bit odd. While the notion of carb-on-carb is not something that has passed me by over the years (potato pizza, anyone??), I don’t think it will quite work here.
But that’s the only exception! 😂
Here’s what I use.
Now, I confess these were not just dregs of my fridge – I specifically wanted to use the same veggies I used in the Marinated BBQ Vegetables so I could use the same clips in the video to show that you can either roast OR BBQ the vegetables. 😇
But here’s a photo from another time I made this Vegetarian Pasta Salad using other vegetables (I spy cauliflower and broccoli) and also a mix of leftover pasta I had.
Marinade-Dressing for vegetables (double duty!)
And here’s the marinade / dressing I use for this pasta salad recipe. You get great bang for your buck with this marinade:
When you toss hot vegetables in a dressing, they suck up the flavour which makes the veggies even tastier;
As the veggies marinate, they sweat and creates tasty juices which makes this pasta salad extra juicy and tasty; and
Hold back some of the dressing to add a fresh hit of flavour at the end.
I make this a LOT!
I make this Vegetarian Pasta Salad a LOT. This, along with Baked Frittata, is one of my favourite ways to use up leftover vegetables at the end of the week because they can be made with any roast-able vegetables, and it lasts for days and days so you can make it now when your veggies are at the end of their life, but eat it later.
Some more Leftover Veg favourites include: Vegetarian Lasagna (double up on veg and skip the ricotta layer), Cheesy Vegetable Pasta and this One Pan Roasted Vegetables and Seasoned Rice.
How to serve it
Serve this Vegetarian Pasta Salad as:
a side dish to anything (well, perhaps anything non-Asian!)
a meal in itself
work lunch!
GREAT for potlucks and gatherings – transportable, colourful, and of course super delish
serve it at room temp OR slightly warm
And while it is meat free, you could certainly add a hit of protein by adding some shredded chicken! – Nagi x

Instructions
Marinade/Dressing:
- Place ingredients in a jar and shake well. Set aside 10 minutes+.
Roasted Vegetables:
- Preheat oven to 250°C/480°F (230°F fan) – super high heat replicates BBQ charred edges.
- Toss veggies in oil – Place all vegetables other than asparagus in a large bowl. Drizzle with oil, sprinkle with salt, pepper and garlic, toss.
- Spread vegetables on 2 trays (fill one less than the other). Roast 25 minutes, tossing once.
- Add asparagus – Drizzle asparagus with oil and pinch of salt and pepper. Add into oven for last 5 minutes.
- BBQ Option: See Marinated BBQ Vegetables for directions.
Pasta salad:
- Marinate veggies – Transfer vegetables into large bowl, pour over 1/2 the Dressing. Toss, then leave to marinate for 30 minutes to 3 hours.
- Cook pasta + 2 minutes: In large pot of salted water, cook pasta per packet directions but ADD 2 minutes to the cook time (Note 5 for why). Drain and return pasta into pot.
- Add vegetables, including veg juices, into the pasta pot. Add remaining Dressing and parsley, then toss. Set aside for 15 minutes to cool slightly.
- Serve! Sprinkle with feta and serve! Keeps 4 – 5 days, serve at room temp.
Make ahead PRO TIP (Note 4):
- SCOOP OUT a mug of pasta cooking water just before draining. Add 3 tbsp water to reserved Dressing (after marinating veg), shake well. Use this Dressing per above, but reserve 3 tbsp to freshen up pasta salad on Day 2 onwards.
- Freshen up pasta salad: Bring to room temp or briefly microwave (cold pasta = dry) to warm gently. Toss with Reserved Dressing then serve.

Potato Wedges. He doesn’t have quite the same response with vegetables. 🤷🏻♀️
SO delicious! I’m not a huge pasta salad person, but I love roasted veggies so I tried it out. This is probably the best recipe I’ve made in months. Flavorful, flexible, easy! This is my first recipe from this site but won’t be my last.
Welcome!! So glad that you enjoyed it!! N x
Made this for our Lunch Club group and it was praised mightily.
More importantly are you okay Nagi? II miss seeing new posts.
I’m fine! Just working hard on the cookbook!! N x
This pasta salad is sooo refreshing and delicious. My boyfriend and I had it for 4 days straight and we agreed we would be happy eating this every day. Added it to my rotation. Thank you 🙂
Hi Nagi and Dozer, I had this at a friends a while back. She’s one of your followers too. Just made it myself. Used heirloom carrots, broccoli, red onion, bell peppers and zucchini. It is delicious! Thankyou. 😁😋🇨🇦
I just made this recipe today, and it was so good. Its taste was very good. Thank you for sharing with us.
Made this today so delicious. My oven wouldn’t go up to 480F today so I broil the vegetable instead it turned out better than I thought, follow the recipe instruction it’s perfect it’s soooooo good! Another awesome recipe for keep! Thanks Nagi and Dozer
I did not expect this to be as delicious as it was. I added hot smoked salmon and it was so moreish. This will now be on high rotation in my house.
Can’t wait for you n Dozer to be back.
This recipe was absolutely delicious. I made it the day before and followed all tips – it worked out perfectly!
Everyone enjoyed it.
I roasted the veggies in our Weber q and it added great flavour.
This is the best pasta salad I have ever tasted hands down. Good riddance to pasta salad with raw veggies and mayonnaise this is the bomb. I used peppers, red onions, mushrooms, asparagus topped with feta cheese and olives. It really cold here in Canada as we are deep in our winter 🥶 I can’t imagine how delicious this will be in the summer. Thank you very much for sharing this killer pasta salad. I followed the recipe and the dressing is over the top deliciousness!!!.
The flavors were excellent. But, there was a little too much pasta for me. Next time I make this I will add the pasta to the vegetables, instead of the other way around.
Changed my mind. The pasta was just right.
Served this up to book club group. Everyone asked for the recipe. And fortunately for us, they didn’t quite finish it all, so we got to have leftovers the next day!!
As always a delicious pasta salad..BTW did you get the message I sent you on your gmail?
I love this vegetable medley and the dressing is perfect. I’ve made it a few times now and it’s so versatile. I used it on a toastie this morning, along with your sauerkraut and it was delicious. Thank you.
Hands down the BEST pasta salad I’ve tasted. The dressing is really the key element for the flavours.
I also put handfuls of spinach in when I added the pasta, which wilted through for extra greens.
I love making pasta with roasted vegetables. This one looks amazing. I love all the colors!
This salad is so beautiful Nagi! I added a little bacon, can’t wait to try it with chicken next time!
Had a lot of veggies in the fridge to use up and came across this recipe. Didn’t have lemon so had to substitute with lime. OMG this is now my favourite pasta salad recipe! Your recipes never disappoint Nagi.
Ooh this is a little bit naughty! 6 serves only lasted us 3 🥴 Probably the best pasta salad I’ve had. A keeper for sure…..
it’s a pity that it’s winter here, all these recipes with summer vegetables make your mouth water, while we endure the cold, the fog and the frostbite 😉
We have to keep it under the elbow for a further few months, while you enjoy it in the South
Best, Dom
