The Easy Roasting Process
We use a high-heat method to get those crispy edges. You will toss everything in a simple herb-infused oil first. Using parchment paper makes the final cleanup a total breeze. It is a foolproof way to master seasonal cooking.
What You Will Need
- 3 medium carrots, peeled and sliced into 1-inch bias cuts
- 2 large parsnips, peeled and sliced into 1-inch chunks
- 1 large sweet potato, peeled and cut into 1-inch cubes
- 1 medium red onion, cut into 1-inch wedges
- 3 tablespoons extra virgin olive oil
- 1 teaspoon kosher salt
- 0.5 teaspoon cracked black pepper
- 1 tablespoon fresh rosemary, minced
- 1 tablespoon fresh thyme leaves
Step-by-Step Instructions
- Preheat the oven to 400°F (200°C) and line a heavy-duty rimmed baking sheet with parchment paper.
- In a large stainless steel mixing bowl, combine the carrots, parsnips, sweet potato, and red onion wedges.
- Emulsify the olive oil, salt, pepper, rosemary, and thyme, then pour over the vegetable medley.
- Toss the ingredients thoroughly until each piece is uniformly coated with the oil and herb mixture.
- Distribute the vegetables across the prepared baking sheet in a single layer, ensuring sufficient headspace between pieces to prevent steaming.
- Transfer the sheet to the center rack of the oven and roast for 45 minutes.
- At the 20-minute mark, use a flat spatula to turn the vegetables to ensure even caramelization on all surfaces.
- Verify tenderness with a paring knife; the vegetables should be soft in the center with charred, golden-brown edges.
- Remove from the oven and rest for 5 minutes before service to allow the sugars to set.

Make-Ahead Advice
Keep leftovers in an airtight container in your fridge. They will stay fresh for up to four days. To reheat, use your oven or air fryer at 350°F. This helps maintain that signature crisp texture you love.
Avoid the microwave to prevent them from getting soggy. You can prep the veggies a day in advance. Store them dry in the fridge until you are ready to roast.
