Preheat oven to 425°F. Line a large baking sheet with foil or parchment paper.
Slice the carrots diagonally in 1-inch-thick slices. Toss them in a bowl with the olive oil, salt, and pepper. Transfer to the prepared sheet pan, spreading them out in a single layer.
Roast in the preheated oven for 20-25 minutes, until they’re browned and fork tender. Roasting time may vary depending on the size of the carrots.
Sprinkle chopped parsley on top, if desired and serve warm.

Notes
Storage: Store any leftovers in an airtight container. They will last about 5-6 days in the fridge.You can freeze the roasted carrots, but I wouldn't recommend it unless you have a lot leftover and no one to eat them. If you do freeze them, I recommend you repurpose them by blending in a soup!Make Ahead Tips: Save some time by peeling and slicing the carrots in advance. To keep them fresh in the fridge, store them in a bowl of water. Then drain and pat dry before preparing to cook.Serving Size: One serving is about 2-3 carrots sliced.
