Warm Roasted Veggie Potato Salad

Sheet pan roasted potatoes and vegetables tossed warm with Italian dressing and fresh basil. This version skips mayonnaise for a lighter, tangy profile that works as a side dish or vegetarian main. Serve alongside grilled proteins or as part of a summer spread. The vegetables caramelize slightly in the oven while potatoes turn creamy, creating textural contrast.

Don't crowd the baking sheets. Spread vegetables in single layer so they roast rather than steam; work in batches if needed.
Toss warm while vegetables are still hot so dressing coats everything evenly and flavors meld.
Cut vegetables to similar sizes for even cooking.

FAQ
Can I make this ahead?
Yes. Prep and season vegetables up to 8 hours in advance, cover, and refrigerate. Roast within 2 hours of serving for crispest texture. Reheated leftovers work but texture softens slightly.
What if I don't have light Italian dressing?
Mix 1/4 cup olive oil with 2 tablespoons red wine vinegar, 1 minced garlic clove, 1 teaspoon dried Italian herbs, salt, and pepper. Adjust ratio to taste.
How long does this keep?
Refrigerate in airtight container up to 4 days. Flavor deepens after 24 hours as vegetables absorb dressing. Best served warm; reheat gently in 325F oven 10-15 minutes or at room temperature.
