Preheat your oven to 400 degrees F. Add the olive oil to a large skillet over medium high heat. Add the carrots, onion and thyme and toss to coat in the olive oil. Sprinkle with salt and pepper and transfer the skillet, carrots and all into the oven, and roast for 15 minutes until the carrots are fork tender.
Once the carrots are tender, remove the skillet from the oven and place it back onto the stove top. Drizzle the honey over the carrots and toss gently to coat. (BE CAREFUL not to touch the skillet - it's HOT - and I've burned myself more time that I care to remember)
Season with more salt and pepper if needed.
