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.

Before you start

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.

  • Heavy-duty rimmed baking sheet
  • Large mixing bowl
  • Chef's knife
  • Parchment paper
Ingredients

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
The key technique

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.

Step by step

The method.

  1. Preheat your oven

    Set your oven to 325°F (160°C). Position the rack in the center to allow even air circulation.

  2. 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.

  3. Season and toss

    Drizzle the oil over the vegetables and add the salt. Toss until every piece has a thin, glossy coating of oil.

  4. 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.

  5. 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.

  6. Finish

    Remove from the oven and sprinkle with the fresh thyme while they are still hot to release the herb's aromatics.

Variations

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.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Skip the non-stick spray; use real oil for better browning.

Tip

Dry your washed vegetables with a kitchen towel before cutting to ensure they roast rather than steam.

Tip

If you want crispier edges, increase the heat to 400°F for the final 10 minutes.

Questions

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.
