Roasted Root Vegetables
Root vegetables have a dense structure that benefits from sustained, dry heat. When treated correctly, the natural sugars caramelize against the hot metal of the pan, creating a crisp, browned crust that offsets the soft interior.
Uniformity is your primary goal.
If your pieces are wildly different in size, the small bits will burn before the larger chunks are tender. Take the extra minute to keep your knife cuts consistent.
- Heavy-duty rimmed baking sheet
- Chef's knife
- Large mixing bowl
- Parchment paper
What goes in.
- 1 lbcarrots, peeled and cut into 1-inch chunks
- 1 lbparsnips, peeled and cut into 1-inch chunks
- 1 lbred potatoes, scrubbed and quartered
- 3 tbspgrapeseed or avocado oil
- 1 tspkosher salt
- 1/2 tspfreshly cracked black pepper
- 1 tbspfresh thyme leaves
Preheat the Sheet Pan
Slide your empty baking sheet into the oven while it preheats. Placing cold vegetables onto a searing-hot pan jumpstarts the browning process the second they touch the surface.
The method.
Heat the oven
Set your oven to 425°F. Place the empty baking sheet on the center rack while it heats up.
Prepare the vegetables
In a large bowl, toss the carrots, parsnips, and potatoes with the oil, salt, and pepper until every surface has a thin, even sheen.
Arrange the pan
Carefully remove the hot pan from the oven. Spread the vegetables in a single layer. Do not allow them to overlap, as trapped moisture will lead to steaming.
Roast
Return to the oven. Roast for 30 minutes, turning the pieces halfway through to ensure color on all sides.
Finish
The vegetables are done when a fork slides into the center of a potato piece with zero resistance and the edges show a deep, chestnut-brown color. Toss with fresh thyme before serving.
Other turns to take.
Sweet and Spicy
Toss the raw vegetables with a tablespoon of maple syrup and a pinch of dried chili flakes before roasting.
Hard Root Mix
Add cubed rutabaga or celery root to the mix, though these may require an extra five minutes in the oven.
When it doesn't go to plan.
Pat the vegetables dry with a clean towel after washing; excess water on the surface prevents browning.
If using a metal baking sheet, skip the parchment paper for better heat transfer directly to the vegetables.
Do not crowd the pan; if the vegetables are touching each other, they will stew in their own moisture.
The ones that keep coming up.
Why are my vegetables mushy?
You likely crowded the pan, which traps steam. Use two pans if you are cooking a large batch, or ensure there is at least an inch of space between each piece.
Can I use olive oil?
Use a refined olive oil or a neutral oil like grapeseed. Extra virgin olive oil can burn at 425°F and develop an acrid taste.
