For standard oven-roasted carrots at high heat, plan on about 20–30 minutes, depending on size and cut, at around 425°F (220°C).

Quick Scoop: Timing basics

  • Whole medium carrots at 425°F: about 25–30 minutes, stirred once or twice, until fork‑tender but not mushy.
  • Thick chunks or large batons at 425°F: about 20–25 minutes, again checking for tenderness and browning.
  • Baby/small carrots at 425°F: about 18–20 minutes if fairly thin, up to 25 minutes if larger.
  • Pre‑parboiled carrots (briefly boiled then roasted): roast 30–40 minutes at a slightly lower 200°C (about 400°F), since they start partially cooked.

A good rule of thumb: start checking at 15 minutes, then every 5 minutes, and pull them when a fork slides in easily and the edges are caramelized but not burned.

Simple step‑by‑step

  1. Heat oven to 425°F (220°C).
  1. Peel if you like, cut carrots into evenly sized sticks or leave whole if not too thick.
  1. Toss with oil, salt, and pepper (plus honey or herbs if you want).
  1. Spread in a single layer on a parchment‑lined baking sheet.
  1. Roast 15–25 minutes (up to 30 for thick/whole carrots), flipping once, until browned and fork‑tender.

Quick tip: If your carrots burn before they soften, lower the oven to 400°F and cut them a bit thicker next time so they have time to cook through before the outside gets too dark.

TL;DR: For most home ovens, roast carrots at 425°F (220°C) for roughly 20–30 minutes, adjusting time for thickness and checking with a fork near the end.
