Vegan Pasta Salad with Lemon, Basil, and Cherry Tomatoes

This is the ultimate vegan pasta salad for summer picnics and barbecues. Easy to make, packed with flavor, and a perfect BBQ side, it’s one of those dishes people often call their favorite pasta salad ever. With plenty of roasted vegetables, a tangy balsamic roasted-garlic vinaigrette, and tender pasta, this salad is both satisfying and refreshing.

I’m not usually a huge salad fan, but combine pasta and lots of roasted vegetables and I’m instantly converted. Roasting brings out the vegetables’ natural sweetness and depth, so you end up with a colorful, hearty salad that still feels light and summer-ready.

This vegan pasta salad is loaded with vibrant veggies, tossed in a roasted garlic and balsamic vinaigrette, and finished with baby greens. It’s vegan by design but full of texture and savory depth—no one will miss dairy or meat in this dish. It also adapts easily to gluten-free diets by swapping in gluten-free pasta.

Ingredients

A great pasta salad needs variety. I use a mix of roasted vegetables for color, flavor, and texture. For this recipe, use:

• Zucchini
• Asparagus
• Bell peppers
• Onion (finely chopped for a little crunch)
• Mushrooms (cremini or similar)

I roast the vegetables in the oven rather than grilling, which saves attention time and concentrates their flavor. For extra crunch, you can add toasted sunflower seeds or walnuts when serving.

Tip: choose a short pasta shape with nooks for the dressing to cling to—fusilli or rotini work especially well. Slightly overcooking the pasta by a minute or two (compared with al dente) keeps it tender after it cools, but avoid letting it get mushy.

What’s the best pasta for pasta salad?

Short, twisted shapes like fusilli or rotini are ideal because they trap dressing and small bits of vegetables. Cook the pasta a minute or two longer than al dente so it stays tender once chilled, but be careful not to overcook.

Roasted garlic vinaigrette

Roasted garlic is central to this salad. Raw garlic can be sharp, but when roasted it becomes sweet, mellow, and spreadable—ideal for blending into a creamy-smooth vinaigrette. Mix the roasted garlic with balsamic vinegar, extra virgin olive oil, salt, and freshly ground black pepper to dress the pasta and vegetables.

How to Make Vegan Pasta Salad

This recipe is straightforward. Here’s the simplified method so you can follow along easily.

1. Preheat the oven to 400°F (200°C).
2. Roast the garlic: slice the head of garlic in half (leave the papery skins on), drizzle the exposed cloves with a little olive oil, sprinkle with salt, wrap in foil, and roast for about 45 minutes until soft and caramelized.
3. While the garlic roasts, chop bell peppers, zucchini, asparagus, and mushrooms into roughly 1-inch pieces. Toss them with olive oil and a pinch of salt, and spread out on a baking sheet.
4. When the garlic is done, put the vegetables in the oven and roast for 25–30 minutes, turning once so they brown evenly.
5. Boil a large pot of salted water and cook 12 oz short-cut pasta according to package directions, adding a minute to the recommended time so the pasta stays tender as it cools. Drain and set aside.
6. Make the vinaigrette in a large bowl: squeeze the roasted garlic cloves from their skins into the bowl, add 1/4 cup balsamic vinegar, 3 tablespoons extra virgin olive oil, and 2 teaspoons fine sea salt, then whisk until smooth. Add freshly ground black pepper to taste.
7. Toss the warm pasta with the vinaigrette, add the chopped onion, 1/2 cup pitted green olives (finely chopped), and the roasted vegetables. Mix gently to combine.
8. Let the pasta salad cool slightly, then fold in 5 oz baby greens just before serving so they remain fresh and bright.
9. Allow the salad to rest 30 minutes to an hour if possible so the flavors meld. Serve at room temperature or slightly chilled.
