Step 1

Preheat oven to 450F/230C.

Step 2

Peel carrots if desired. Cut carrots on diagonal into slices about 1/4 - 3/8 inch thick. Toss carrots with 1 T olive oil, thyme, salt, and pepper.

Step 3

Spread carrots on large roasting pan (it should be big enough that the carrots are in a single layer). Roast carrots 15 minutes.

Step 4

While carrots are roasting, wash mushrooms and spin dry or dry with paper towels. Slice mushrooms into even slices, slightly thicker than carrots.

Step 5

Using the same bowl as you tossed the carrots in, toss mushrooms with 1 T of olive oil.

Step 6

Remove carrots from oven, stir, add mushrooms and roast 10-15 minutes more.

Step 7

Serve hot, sprinkled with fresh parsley if using.
