This side dish is so much tastier than its short list of ingredients might have you think. The vegetables’ natural sweetness is enhanced as they slowly cook in the even heat of the oven. Stirring the roasted carrots and onions often helps them cook evenly to a pleasant, tender texture. You can easily add more root vegetables to the mix to use what you have on hand, reason enough to make this recipe on repeat through the cold weather months.

Ingredients for Roasted Carrots and Onions

  • Baby carrots: The baby carrots play are the star of this roasted vegetable recipe. High in natural sugars, carrots caramelize slightly as they roast in the oven.
  • Onions: Yes, four onions sounds like a lot, but onions soften considerably in the heat of the oven. The onions add a delicious, sweet and savory flavor to the carrots.
  • Garlic: The garlic roasts to a soft and mellow flavor.
  • Olive oil: The oil helps the roasted carrots and onions caramelize and soften. Choose a good olive oil with bright, bold flavor.
  • White wine vinegar: Because the vegetables sweeten as they roast, a splash of wine vinegar provides a tangy brightness to balance out the flavor.
  • Thyme: Dried thyme adds a layer of deep, savory flavor to the vegetables as they roast. A sprinkle of fresh thyme adds a welcome pop of green to the finished dish, but it’s an optional touch.

Directions

Cover the pans with foil and bake for 20 minutes. Remove the foil, stir the vegetables and return them to the oven. Bake, uncovered, for another 10 minutes; stir again. Bake for a final 10 minutes, or until the onions are soft and the carrots are crisp-tender. If desired, sprinkle with fresh thyme.

Roasted Carrots and Onions Variations

  • Swap the veggies: Use sliced leeks in lieu of the onions or replace some of the carrots with parsnips for a two-tone version of this sweet and savory dish.
  • Spice it up: For some heat, add 1/2 teaspoon chili powder and a dash of cayenne pepper.
  • Add some sweetness: Sprinkle the carrots and onions with 3 tablespoons brown sugar or a splash of maple syrup.
  • Use larger carrots: If you don’t have baby carrots on hand, use medium carrots; cut them into 2-inch pieces and roast for 25 minutes. Skip the especially large carrots, though; they tend to have a woody texture.

Yes, you can use this recipe to cook almost any root vegetable.
