How to Make Vegan Fall Pasta Salad

Roast the Vegetables

Preheat your oven to 400°F (200°C).

Spread the Brussels sprouts, sliced leeks, sweet potatoes, mushrooms, and chopped garlic on a large baking sheet. Drizzle with olive oil, sprinkle with salt, and toss until everything is evenly coated.

Roast for 20–25 minutes, stirring halfway through, until the vegetables are tender and lightly caramelized. The sweet potatoes should be soft, and the Brussels sprouts should have beautifully crisp edges.

Cook the Pasta

While the vegetables roast, bring a large pot of salted water to a boil.

Cook the pasta according to the package directions until al dente. Drain well and rinse briefly with cool water if serving the salad chilled. Allow the pasta to cool slightly.

Prepare the Creamy Poppy Seed Dressing

In a small mixing bowl, whisk together the vegan mayonnaise, olive oil, apple cider vinegar, agave syrup, Dijon mustard, poppy seeds, salt, and onion powder until smooth and creamy.

Taste and adjust the seasoning if needed. Add a splash of vinegar for extra brightness or a little more agave if you prefer a sweeter dressing.

Assemble the Salad

Transfer the cooked pasta to a large serving bowl.

Add the roasted vegetables and gently toss everything together.

Pour the creamy poppy seed dressing over the salad and mix until every piece of pasta and every vegetable is evenly coated.

Serve immediately while slightly warm, or refrigerate for an hour to allow the flavors to meld before serving chilled.

Tips for Success

• Roast the vegetables in a single layer for the best caramelization.
• Avoid overcooking the pasta so it maintains a firm texture.
• Stir the vegetables halfway through roasting for even browning.
• Allow the roasted vegetables to cool slightly before mixing with the dressing.
• Make the dressing ahead of time to deepen its flavor.
• Toss the salad again before serving if it has been refrigerated.
