Roasting carrots at 350°F (175°C) typically takes about 25-35 minutes, depending on the size and thickness of the carrots. Here's a general guideline for roasting carrots at this temperature: 1. Preheat your oven to 350°F (175°C). 2. Wash, peel, and cut the carrots into your desired size and shape. Thicker carrot pieces may require a slightly longer cooking time. 3. Toss the carrot pieces with a drizzle of olive oil and your preferred seasonings. 4. Spread the carrots in a single layer on a baking sheet, ensuring they're not crowded. 5. Roast the carrots in the preheated oven for about 25-35 minutes, checking periodically and giving them a gentle stir halfway through. 6. The carrots are ready when they are tender and slightly caramelized on the edges. You can test their doneness by piercing them with a fork; they should be easy to pierce but not mushy. Keep in mind that cooking times can vary based on factors like the size of the carrot pieces and the specific characteristics of your oven. It's a good idea to start checking the carrots around the 25-minute mark and adjust the cooking time as needed to achieve your desired level of doneness.
