Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper.

In a large mixing bowl, combine diced potatoes, sliced carrots, and zucchini. Drizzle with olive oil, add minced garlic, thyme, rosemary, salt, and pepper, and toss until evenly coated.

Spread the seasoned vegetables in a single layer on the prepared baking sheet.

Roast the veggies for 25-30 minutes, stirring halfway through until golden brown and fork-tender.

Sprinkle chopped parsley over the veggies before serving warm.
