Cut the carrots to a uniform thickness or pieces. I kept mine whole, cutting some of the bigger ones in half. You can also cut them into 2 inch chunks.
Whisk together olive oil, vinegar, thyme, and oregano.
Toss the carrots in the olive oil mixture then spread on a baking sheet. Add salt and pepper, to taste.
Cut the garlic cloves in half, leaving smaller ones whole, then mix in with the carrots.
Roast until tender, 35-40 minutes. Stir the carrots half-way though.
