Ingredients You’ll Need

Individual ingredients for roasted rainbow carrots on a table.

Carrots. I’m using baby rainbow carrots, but regular sized carrots would work, too.

Extra Virgin Olive Oil. We’re going to mix the spices and olive oil together to help the seasoning stick to the carrots. The oil also helps the carrots caramelize when roasting.

You can also use canola oil or avocado oil.

Brown Sugar. This adds a nice sweetness and caramelization to the carrots. You can also use granulated sugar, but you’ll lose the molasses notes that you get from brown sugar.

Dijon Mustard. A little bit of dijon helps balance the sweet notes from the sugar and carrots.

Herbs & Spices. All you need is a little bit of garlic powder, black pepper, and kosher salt. I also like to use some fresh thyme, which adds a really nice savory flavor.

You can also try adding some dried rosemary with the thyme.

Kitchen Tools

For this recipe, you’ll need a sheet pan with parchment paper and a large mixing bowl.

How to Make Roasted Rainbow Carrots

A glass bowl on a table filled with carrots tossed in spices and olive oil.

Preheat the oven to 400°F. Line a baking sheet with parchment paper and set aside.

In a small bowl, whisk together the olive oil, dijon, thyme leaves, and spices.

Add the carrots and brown sugar to a large mixing bowl. Drizzle the olive oil mixture over the carrots and toss to combine, making sure everything is evenly coated.

Pour the carrots onto the baking sheet, spreading them out in a single layer to leave some space between the carrots.

Roast in the oven for 30-40 minutes, or until the carrots are fork tender.

Recipe Variations

  • Make this spicy by adding a dash of hot sauce, cayenne pepper, or red pepper flakes.
  • Try adding some maple syrup for a maple dijon sauce, or honey to the seasoning mixture for a honey glaze.
  • For a sweet and tangy flavor, add a few tablespoons of balsamic vinegar to the oil mixture to make a balsamic glaze.
  • Try adding a squeeze of lemon juice or some lemon zest right before serving for a bright fresh flavor. Or orange zest for the holidays.
  • Try adding other veggies like parsnips, sweet potatoes, onion, or butternut squash.
  • If you’d like even more flavor, cut the top off of a garlic bulb, drizzle with olive oil, and add to the roasting pan to caramelize for roasted garlic.

Recipe Tip! For roasting vegetables, you want the temperature at 400°F-425°F to achieve the best caramelization. Check them about halfway through and use a spatula to flip everything over if needed.

Frequently Asked Questions

How long should you roast carrots for in the oven?

This depends entirely on how thick your carrots are, and what temperature you set your oven for. A good roasting temperature of 400°F will take anywhere from 20 minutes to 40 minutes, with the thicker carrots taking longer. If you don’t have a lot of time, cut the carrots into smaller pieces and check them about halfway through to see if they’re close to fork-tender.

Recipe Tip! Give the carrots a little space on the baking sheet. If they’re layered on top of each other, they’ll steam instead of roast.

Storage

Refrigerate leftover rainbow carrots for 2-3 days in an airtight container.

Freeze leftover carrots for 2-3 months in a freezer-safe container. The texture of the carrots can change after being frozen, so I recommend just making them fresh instead.

Cooking Tips

  • I like to line my baking pan with parchment paper to keep the carrots from sticking. You can also grease the baking pan instead.
  • If you washed the carrots beforehand, use a paper towel to dry them well before adding the seasoning, or the oil won’t stick.
  • Technically you don’t need to peel the carrots, just wash them thoroughly.
