Ingredients for roasted carrots and onions

This recipe is very simple: there’s not too much technique required and no unusual ingredients. But we’ve got a few tricks to take the flavor over the top! Here’s what you’ll need for roasted carrots and onions:

• Carrots: Your large, run of the mill carrots work great here. You could also do long slender bunches of carrots, but you’ll need to weigh them without the greens. Rainbow carrots would look beautiful. What not to use? Baby carrots. Their flavor is engineered to be overly sweet.
• Red onion and yellow onion: Use two different colors of onions for a little variation in flavor and color. The contrast between purple of the red onion and the orange carrot is particularly nice.
• Balsamic vinegar & olive oil: The vinegar gives the veggies a bit of acidic brightness.
• Garlic powder & dried thyme: Thyme goes particularly well with carrots, but you could omit if you don’t have it on hand.
