Step 1

Preheat oven to 400 degrees Fahrenheit (200 degrees Celsius). Scrub potatoes and cut into 1-inch cubes. Peel carrots and cut into 1-inch pieces. Trim zucchini and cut into 1-inch cubes.

Step 2

In a large mixing bowl, combine potatoes, carrots, and zucchini. Add minced garlic, olive oil, chopped rosemary, chopped thyme, salt, and black pepper. Toss to coat all vegetables evenly.

Step 3

Spread the seasoned vegetables in a single layer on a large baking sheet. Avoid overcrowding.

Step 4

Roast for 20 minutes. Carefully remove the baking sheet from the oven and toss the vegetables to ensure even browning.

Step 5

Return the baking sheet to the oven and roast for another 15-20 minutes, or until the potatoes and carrots are fork-tender and golden brown, and the zucchini is tender.

Step 6

Remove from oven. If desired, sprinkle with grated Parmesan cheese before serving.
