Heat oven to 450. Cut potatoes into wedges and slice carrots into rounds. [My sister peels her carrots, but I don't. It's totally your call]. Place potatoes, carrots and garlic in a rimmed baking sheet or 9x13" pan. Drizzle olive oil and sprinkle salt/pepper on top. Mix everything together so veggies are evenly coated with oil and spices. Bake for 20 mins, flipping veggies over halfway through if you like.
