Preheat your oven to 425°F (220°C).
Line a rimmed baking sheet with parchment paper.
In a large bowl, combine the small red potatoes, baby carrots, and the wedges of Vidalia onion.
Drizzle the olive oil over the vegetables and toss well to ensure they are evenly coated.
Add the minced garlic, salt, and pepper to the bowl. Toss once more to combine all the ingredients.
Spread the vegetables out in a single layer on the prepared baking sheet.
Place the baking sheet in the preheated oven and roast for about 30 minutes.
Halfway through the cooking time, take a moment to turn the vegetables.
Once the vegetables are done roasting, remove them from the oven and transfer them back to a large bowl.
Add the chives, lemon zest, and lemon juice to the warm vegetables.
Serve the Lemon Chive Roasted Vegetables immediately.
