Celery root, or celeriac, can be a bit intimidating if you’ve never worked with it before. Choose one that feels dense/heavy for its size. A sharp knife or heavy-duty veggie peeler will take care of the thick skin, no problem! The smoked paprika in this recipe adds an extra depth of smokiness to the caramelized notes of the roasted veggies, but feel free to use regular paprika for a milder flavor, or hot paprika if you like more spice.
