Why You’ll Love This Recipe

Here are three reasons why this roasted carrots recipe is a keeper:

  • Perfect for picky eaters. Roasted carrots taste much better than carrots prepared using any other way. I often tell people who claim they don’t like carrots that they need to try them roasted with caramelized onions.
  • Crowd-pleasing side with minimal effort. Whether you’re a beginner or a trained chef, this recipe is EASY. Simply peel and chop the carrots, toss them with oil and seasonings, and let the oven do the work while you prepare the onions.
  • Budget-friendly. Carrots and onions are cost-conscious, readily available ingredients, so you can create a flavorful and satisfying dish without breaking the bank.

Ingredient Notes

Here is a brief overview of the ingredients you’ll need to make this recipe:

  • Carrots – Select firm, fresh carrots that are relatively uniform in shape so they’re easier to cut into even-size sticks.
  • Extra Virgine Olive Oil – You will need 2 tablespoons to coat the carrots before roasting and 2 tablespoons to sauté the onions.
  • Maple Syrup – It gives the dish a warming, pleasantly sweet quality while helping achieve roasted carrots with perfectly caramelized exteriors and tender, juicy interiors.
  • Coriander – Seasoning with coriander complements the carrots’ natural sweetness with a citrusy, slightly spicy element. It’s worth noting that the dried seeds from the Coriandrum sativum plant are called coriander in the U.S. In contrast, the leaves and stems are called coriander, and dried seeds are called coriander seeds internationally.
  • Yellow Onion – Combining roasted carrots with sautéed onions creates a delicious balance of irresistibly umami-forward flavor. Moreover, sautéed onions offer a soft yet slightly crisp textural contrast to the tender carrots.
  • Apple Cider Vinegar – Balances the natural sweetness of the carrots with a tangy, slightly sweet flavor. If you need a substitute, freshly squeezed lemon or orange juice works, though the flavor of the finished dish will be slightly different.
  • Fresh Parsley – Or cilantro to sprinkle over the roasted carrots and onions for a pop of color and vibrant, herbaceous flavor.

How to Make Roasted Carrots with Caramelized Onions

Here are the step-by-step instructions on how to make this recipe:

  1. Prepare for roasting: Preheat the oven to 400℉.
  2. Chop the carrots: Wash and peel the carrots, then cut each one into 2-inch-long pieces. From there, cut each piece into ½-inch wide sticks.
  3. Season the carrots: Place the carrot sticks in a baking dish, and toss them with olive oil, maple syrup, coriander, and salt. Spread the carrots over the baking dish in an even layer.
  4. Roast the carrots: Transfer the baking dish to the oven, and roast until the carrots are tender and start caramelizing (about 30 minutes), turning with a spatula after about 15 minutes. Cooking time might vary slightly depending on the size of the carrot sticks.
  5. Sauté the onions: Heat olive oil in a pan over medium-high heat, then add the sliced onion and sauté until soft and caramelized (8-10 minutes).
  6. Assemble and serve: Once the carrots are roasted, drizzle the apple cider vinegar over the top, add the caramelized onion, and toss to incorporate. Sprinkle with chopped parsley or cilantro, and enjoy!

Recipe Tips

Here are a few tips to help you make the best roasted carrots and onions:

  • Be sure to spread the carrots on the baking sheet in a single layer, as crowding can lead to uneven cooking and steaming instead of roasting. If needed, use multiple baking sheets or roast in batches.
  • To promote even browning and prevent sticking, don’t forget to toss the carrots halfway through the roasting process.
  • Cooking times may vary depending on the size and thickness of the carrots, so be sure to check on them periodically as they roast.

Fortunately, coriander is a versatile herb that pairs quite well with other dried spices, such as cumin, dill, parsley, thyme, oregano, rosemary, paprika, and garlic powder.

Feel free to experiment with these seasonings to create coriander carrots with a well-balanced flavor.

You can also add a few fresh thyme sprigs to the carrots before roasting them.

If you love garlic, chop a few garlic cloves and saute them together with the onions.

Serving Suggestions

Vegetable side dish – These caramelized onions and carrots are a great way to add a flavorful and aromatic side of vegetables to practically any meal.

Here are some main dish options that you might like:

Buddha bowl topping – This dish also serves as a tasty topping for grain or leafy green-based Buddha bowls, along with other roasted vegetables and protein sources like chicken, chickpeas, or tofu.

Storing & Freezing

Storing: Leftover roasted carrots and onions are best kept in an airtight container in the refrigerator for 2-3 days. To reheat leftovers, bake at 375°F until the pieces firm back up and are heated through.

Freezing: The veggies will lose their crisp-tender texture during thawing, so I don’t recommend freezing leftovers.

Frequently Asked Questions

Here are a few related questions about roasting carrots and onions:

Can you roast carrots and onions together?

Yes, roasting the carrots and onions together is a suitable alternative to sauteing the onions in a separate skillet.

In this case, toss the sliced onions in olive oil and add them to the baking dish when the carrots are halfway through cooking.

Is it best to peel carrots before roasting them in the oven?

Carrot skins are edible but can be unpleasantly chewy and slightly bitter, especially in larger carrots. So peeling the carrots beforehand is best. I also recommend removing the stem end.

If you decide to leave the skin on, don’t forget to wash the carrots thoroughly before chopping.

Can I make this with baby carrots?

Yes! You can absolutely use baby carrots for this recipe. For the best results, I recommend cutting baby carrots in half lengthwise before roasting.

Can I use red onion for this recipe?

You can use red onion for this recipe. However, I find that yellow onion works better when paired with carrots.
