Roasted sliced carrots turn sweet and tender in the oven, with lightly browned edges and a simple savory seasoning. Cutting them into even pieces helps them cook at the same pace, making this an easy side dish for weeknight dinners or a holiday table.
Ingredients
- 1½ pounds carrots, about 6 medium carrots
- 1½ tablespoons olive oil
- ½ teaspoon fine salt
- ¼ teaspoon freshly ground black pepper
- ½ teaspoon garlic powder
- 1 teaspoon chopped fresh thyme leaves, or ½ teaspoon dried thyme
- 1 teaspoon lemon juice, optional, for finishing
- 1 tablespoon chopped fresh parsley, optional, for serving
Instructions
- Heat the oven. Arrange a rack in the center of the oven and preheat to 425°F (220°C). Line a large rimmed baking sheet with parchment paper for easier cleanup, if desired. The carrots need room in a single layer, so use two pans if one would be crowded.
- Prepare the carrots. Rinse and scrub the carrots, then peel them if you prefer. Trim off the ends. Cut the carrots crosswise into slices about ¼ inch thick. Slice thicker carrots on a diagonal to make broader pieces, but keep the slices roughly the same thickness so they roast evenly.
- Season. Put the carrot slices in a large bowl. Add the olive oil, salt, pepper, garlic powder, and thyme. Toss until the slices are evenly coated. If seasoning directly on the baking sheet, toss them thoroughly before spreading them out.
- Arrange on the pan. Spread the carrots in one layer with a little space between pieces. Avoid piling them up: crowded carrots release steam and soften without browning. If necessary, divide them between two baking sheets.
- Roast until tender and browned. Roast for 18 to 25 minutes, turning the slices with a spatula after about 10 to 12 minutes. Start checking at 18 minutes. They are ready when a fork passes through easily and the edges have some golden-brown spots. Very thin slices may finish sooner; thicker slices can take a few minutes longer.
- Finish and serve. Taste and add a little more salt or pepper if needed. Toss with the lemon juice and parsley, if using, and serve warm.
Tips
- Keep the slices even. Similar thickness matters more than making every slice identical in shape. If the carrots vary greatly in width, halve or quarter the thick ends lengthwise before slicing.
- Give them space. A crowded pan traps moisture, so use a second baking sheet rather than stacking the carrots. For the best browning, roast one pan at a time in the center of the oven, or rotate pans between racks halfway through.
- Adjust the seasoning to suit dinner. Replace thyme with rosemary, dried Italian seasoning, or a pinch of ground cumin. If using fresh garlic instead of garlic powder, add it during the last 8 to 10 minutes of roasting so it is less likely to burn.
- Check early if slices are thin. Carrots can go from tender to very soft quickly. Begin testing with a fork at 18 minutes, especially if you cut them thinner than ¼ inch or your oven runs hot.
Serving Suggestions
Serve the carrots hot alongside roast chicken, baked salmon, pork chops, or a lentil or chickpea main. They also fit well on a holiday plate with mashed potatoes and green vegetables. For a simple finish, add chopped parsley, a squeeze of lemon, or a small knob of butter while the carrots are still warm. For a heartier side, scatter over toasted walnuts or pumpkin seeds just before serving.
Variations
Honey-roasted: Toss the carrots with 1 tablespoon honey or maple syrup along with the oil and seasonings. Watch the pan toward the end because the added sugar can brown quickly.
Smoky and spiced: Replace the thyme with ½ teaspoon ground cumin and add ¼ teaspoon smoked paprika. A pinch of chili flakes gives the batch a little heat.
Parmesan and herbs: Roast the carrots with the oil, salt, pepper, and garlic powder. Sprinkle with 2 tablespoons finely grated Parmesan during the final 3 to 5 minutes, then finish with parsley.
Ginger and sesame: Season with ½ teaspoon ground ginger in place of the thyme. After roasting, add a light drizzle of toasted sesame oil and sprinkle with sesame seeds. Use sesame oil as a finishing touch rather than the main roasting oil, since its flavor is strong.
Storage and Reheating
Let cooked carrots cool, then refrigerate them in a covered, shallow container within 2 hours of cooking. They keep for 3 to 4 days in a refrigerator at 40°F (4°C) or colder. Do not leave them at room temperature for more than 2 hours, or 1 hour if the temperature is above 90°F (32°C). For longer storage, freeze them in a freezer-safe container for up to 2 to 3 months; expect a softer texture after thawing.
For the best texture, reheat the carrots in a single layer on a baking sheet at 375°F (190°C) for about 8 to 12 minutes, until hot throughout. You can also microwave a serving in a covered microwave-safe dish in 30-second intervals, stirring between intervals; this is quicker but will not restore browned edges. If reheating leftovers, heat them until steaming hot throughout. Discard carrots that have been left out too long or show signs of spoilage.
Frequently Asked Questions
Do I need to peel carrots before roasting?
No. Scrub them well under running water and trim the ends; peeling is optional. Peeling can improve the appearance or remove a tougher outer layer on older carrots, but clean, fresh carrots roast well with their skins on.
Can I use baby carrots?
Yes. Slice them lengthwise if they are thick, then cut them into pieces of similar thickness. Whole baby carrots are much thicker than ¼-inch slices and may need longer to become tender, so check them with a fork and roast until done.
Why did my carrots turn out soft instead of browned?
The pan may have been crowded, the oven may not have been fully hot, or the carrots may have been cut very thin. Spread them out in one layer, preheat the oven completely, and use a second pan if needed. A little browning is easiest when excess moisture can escape.
Can I prepare the carrots ahead?
You can wash, peel, and slice them up to a day ahead. Store the raw slices in a covered container in the refrigerator, then dry them if damp and toss with oil and seasonings just before roasting. For the best browning, roast them shortly before serving.
Can I roast carrots at a different temperature?
Yes. At 400°F (200°C), they will usually need about 22 to 30 minutes; at 450°F (230°C), start checking around 15 minutes. Oven performance and slice thickness vary, so use tenderness and browned edges—not time alone—to judge doneness.
How do I know when the carrots are done?
They should be easy to pierce with a fork and lightly browned in places, while still holding their shape. There is no required minimum internal temperature for plain roasted vegetables; tenderness is the practical doneness test.
