Slow-Roasted Root Vegetables
High heat often results in charred skins and raw interiors with dense root vegetables. Slow roasting treats these ingredients with patience, resulting in a buttery, uniform texture that highlights their inherent earthiness.
Uniformity is your primary tool
Cut your vegetables into consistent sizes so they finish cooking at the same time. If pieces vary in size, the smaller ones will disintegrate while the larger ones remain hard.

What goes in.
- 1 lbcarrots, peeled and cut into 2-inch batons
- 1 lbparsnips, peeled and cut into 2-inch batons
- 1 lbYukon Gold potatoes, cut into 1-inch cubes
- 3 tbspneutral oil, such as grapeseed or avocado
- 1 tbspkosher salt
- 1 tspfresh thyme leaves
Low and slow for structural integrity
Roasting at 325°F (160°C) provides enough heat to caramelize sugars but is gentle enough to let the heat penetrate to the center of dense roots without drying out the exterior.
The method.
Preheat your oven
Set your oven to 325°F (160°C). Position the rack in the center to allow even air circulation.
Prepare the vegetables
Place your cut carrots, parsnips, and potatoes into a large mixing bowl. Ensure they are thoroughly dry before adding oil; moisture on the surface creates steam rather than browning.
Season and toss
Drizzle the oil over the vegetables and add the salt. Toss until every piece has a thin, glossy coating of oil.
Arrange the tray
Spread the vegetables in a single layer on the parchment-lined sheet. Do not crowd the pan; if they are piled on top of each other, they will steam and lose their texture.
Roast
Place the tray in the oven. Roast for 60 to 75 minutes, turning the vegetables once halfway through. Look for a deep amber color on the edges and a tip of a knife that slides into the center with no resistance.
Finish
Remove from the oven and sprinkle with the fresh thyme while they are still hot to release the herb's aromatics.
Other turns to take.
Winter Root Medley
Add 1-inch cubes of celery root and golden beets to the mix for additional earthy contrast.
Balsamic Glazed
Toss the vegetables with two tablespoons of balsamic vinegar in the final 10 minutes of cooking.
When it doesn't go to plan.
Skip the non-stick spray; use real oil for better browning.
Dry your washed vegetables with a kitchen towel before cutting to ensure they roast rather than steam.
If you want crispier edges, increase the heat to 400°F for the final 10 minutes.
The ones that keep coming up.
Can I use smaller pieces?
Yes, but reduce the roasting time by 20 minutes to prevent them from becoming too soft.
How do I know when they are done?
The exterior should be wrinkled and deeply golden, and the center should yield completely when pierced with a paring knife.
