Roasted Veggie Pasta Salad

I've made plenty of pasta salads over the years, but this roasted veggie pasta salad-built from oven-roasted vegetables that concentrate natural sweetness-stands out every single time (a cold-or-room-temperature dish commonly served at picnics and potlucks).

Roasting the vegetables brings out their natural sweetness and gives each bite a caramelized, smoky edge that you just can't get from raw or steamed veggies.

Toss that with tender pasta, a simple vinaigrette, and a few fresh herbs, and you've got a dish that tastes like it took hours to make-but only requires about 30 minutes of effort.

Save for Later!

The best part? You can use whatever veggies you have on hand.

This recipe is flexible, forgiving, and perfect for both meal prep and last-minute get-togethers. I've taken it to potlucks, served it at family dinners, and even packed it cold for lunch.

It always disappears fast.

Why You Should Make This Roasted Veggie Pasta Salad

This pasta salad checks every box-easy, nutritious (rich in fiber and vitamins), filling, and full of flavor.

Roasting the vegetables adds depth that raw veggies can't offer, by encouraging Maillard browning and caramelization at high heat. Each bite is slightly crisp on the outside, soft inside, and coated with savory charred edges.

The vinaigrette brings everything together with a light, tangy finish that doesn't overpower.

• Simple ingredients you likely already have

• Boil the Pasta
  Cook pasta in salted water until just al dente. Drain and rinse with cool water to stop the cooking and prevent sticking.
• Make the Vinaigrette
  In a small bowl, whisk together olive oil, lemon juice, Dijon mustard, salt, and a splash of maple syrup or honey (optional) for balance.
• Combine Everything
  Toss roasted veggies and pasta together in a large bowl. Pour the vinaigrette over and mix well. Let it sit for at least 10 minutes so the flavors meld.
• Serve or Store
  Serve right away, or chill and enjoy later. It keeps well and tastes even better the next day.
