Celeriac aka Celery Root, to me, is the freshest tasting root vegetable, bright and earthy and
more delicate than it looks. I first came across this celery root and potato combination in Alice
Waters’ cookbook Vegetables. It skips the usual presence of dairy and instead uses homemade
chicken stock, allowing the celeriac to truly shine.
Ingredients
5 medium russet potatoes
2 medium celeriac
1 large yellow onion
1 cup homemade chicken stock
A few sprigs of thyme, rosemary or marjoram (or a combination of all 3), leaves picked
and chopped
Kosher salt, to taste
Cracked black pepper, to taste
3 tablespoons olive oil
1 tablespoon butter
Instructions
1. Heat oven to 400
2. Peel the potatoes and celeriac, then slice into ¼ inch rounds (use a mandolin for this if
you have one). Slice the onion
3. In a medium oven proof skillet, heat one tablespoon olive oil over medium heat. Add the
onion and cook until softened and starting to get golden around the edges. Season with
salt and pepper. Remove half the onions.
4. Layer the potato and celeriac slices on top of the onion with half of the herbs. Add the
rest of the onion followed by the rest of the potato and celeriac. Sprinkle with the rest of
the herbs
5. Pour the chicken stock over everything along with a healthy drizzle of olive oil and dab
the top with small bits of butter
6. Cover the dish with foil and bake for 30 minutes.
7. Remove the foil and continue baking until the top is golden brown and the vegetables are
tender. Begin checking at the 40 minute mark.
