Best Potato And Celery Root Rosti Recipes

GRATIN OF CELERY ROOT AND POTATO

Steps:

• Preheat the oven to 375 degrees F.
• Slice the potatoes into 1/4-inch-thick rounds. Peel the celery root and cut into 1/4-inch-thick slices to resemble the potatoes.
• Butter a heavy oval casserole dish. Layer the potatoes in the bottom of the dish, followed by the butter and then a layer of celery root. Sprinkle with sea salt. Top with a layer of half of the cheese. Repeat with the remaining potato and celery root. Top with the cream and then the remaining cheese.
• Bake until deep golden brown, about 1 hour.

CELERY ROOT AND POTATO PUREE

Steps:

• Place the potatoes in a pot large enough to accommodate the celery root and the potatoes. Add enough water to cover the vegetables by 2 inches and season generously with salt. Bring to a boil and cook for about 10 minutes. Add the celery root and cook until both vegetables are fork tender. Strain the celery root and potatoes.
• Pour the cream in a small saucepan and bring to a boil. Meanwhile, pass the celery root and potatoes through a food mill into a large bowl. Add one-quarter of the hot cream and 2 pats of the butter. Stir vigorously until the cream and butter are thoroughly combined. Repeat for the remaining cream and butter. Taste for seasoning, you will probably have to add salt. Serve in a warm serving bowl immediately or keep warm until ready to use.

POTATO AND CELERY ROOT ROSTI

Steps:

• Shred potatoes and celery root on the large holes of a box grater. Working in batches, wrap in cheesecloth and squeeze out liquid. Toss with salt in a medium bowl. Season with pepper.
• Preheat oven to 400 degrees. Heat 3 tablespoons oil in a 12-inch ovenproof nonstick skillet over medium-low heat. Spread shredded potato-celery root mixture evenly in skillet; press gently to flatten using a spatula. Cook for 10 minutes. Run spatula around edge to loosen; spoon 2 tablespoons oil around edge. Cook until underside is golden and begins to crisp, 10 to 15 minutes more. Run spatula around edge to loosen; invert onto a plate.
• Add remaining 3 tablespoons oil to skillet. Return rosti to skillet, golden side up; press gently to flatten. Cook, shaking occasionally to loosen, until underside is golden and begins to crisp, about 20 minutes. Transfer skillet to oven. Bake until cooked through, 10 to 15 minutes. Return to plate; cut into wedges. Serve with sour cream.

CELERY ROOT-POTATO PURéE

Steps:

• Put the celery root, potatoes and garlic cloves in a soup pot. Cover with cold water and salt generously, then boil over medium-high heat until tender, about 15 minutes. Drain and press through a ricer or the large holes of a food mill, then return to the pot. (If you prefer a rough-textured purée, mash with an electric beater or a hand-held potato-masher.)
• Over medium-low heat, whisk in the milk or half-and-half until the thickness of the purée is to your liking. It shouldn't be too stiff. Whisk in the butter and incorporate. Taste for salt and adjust. Make sure the purée is heated through. May be made up to 2 hours in advance, held at room temperature, and reheated in a double boiler.
