Instructions

Preheat oven to 400°F. If using two baking sheets, position racks in upper and lower thirds of oven.
Prepare baking sheets with non-stick spray or parchment paper.
Combine vegetables in a large bowl. Add olive oil and Dijon mustard. Toss to coat.
Add seasoning: Sprinkle in Italian herbs, garlic powder, salt, and pepper. Toss again.
Distribute evenly on two baking sheets in a single layer, giving vegetables space.
Roast for 25–35 minutes, tossing halfway and rotating pans. Look for crisp edges and fork-tender texture.
Add Parmesan during last 5 minutes of roasting or after removing from oven.
Serve hot or at room temperature with extra seasoning to taste.

Notes

💡 Notes

Dijon adds flavor depth but can be replaced with more olive oil if preferred.
For extra crispiness, use convection mode at 375°F.
Mix and match veggies based on seasonality — carrots, parsnips, squash, or asparagus work great.
Make-ahead: Roast early and reheat before serving.

📦 Storage & Reheating

Refrigerate: Store in airtight container for up to 5 days.
