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.
Notes
Serve potatoes and carrots on the side of your main dish.
