~ Sweet Potatoes, Red Bliss Potatoes and Celery Root Mash ~
It’s the time of year for soft and fluffy things. This applies to our food as well as our clothes. As we wrap ourselves in wool and light the fire, we contemplate sating meals to comfort and fill our bellies. This simple side will do just that. Sweet and red potatoes are smashed together with celery root in a rustic rendition of fluffy mashed potatoes. Faintly sweet with potato and redolent of roasted garlic, this savory side is mellow and rich, promising to warm us as much on the inside as our fleece is protecting us on the outside.
Sweet and Red Potato Mash
Whole milk Greek style yogurt adds body and creaminess without excess fat to the potatoes. If you prefer extra richness, substitute sour cream for the yogurt. Serves 4-6.
2 pounds red potatoes with skin, cut in 1 inch pieces
1 pound sweet potato, peeled, cut in 1 inch pieces
1/2 pound celery root (celeriac), peeled, cut in 1/2 inch pieces
4 garlic cloves, divided
3 tablespoons unsalted butter, room temperature
1 cup whole milk Greek yogurt or sour cream
1/3 cup finely grated Parmigiano cheese
Freshly ground black pepper
Sage leaves for garnish
Combine potatoes and celery root in a large pot. Peel and smash 3 garlic cloves. Add to the pot. Cover with cold water. Bring to a boil. Reduce heat, cover and simmer until potatoes are very soft. Drain. Return to pot and cool slightly. Mince the remaining garlic and add to the potatoes. Add butter and yogurt. Mash with a potato masher to desired consistency. Stir in cheese. Add salt and pepper to taste. Serve warm, garnished with chopped sage leaves.
If you are searching for holiday side dishes, this root veggie gratin is a fresh alternative to a traditional potato gratin. Layers of rutabaga and sweet potato alternate with red potatoes in this colorfully striated dish flecked with sage. The root vegetables lend an extra dimension to this rustic winter gratin with their sweet earthy flavor, while adding a more nutritious alternative to the simple potato.
Root Vegetable Gratin
16 ounces sour cream
1 garlic clove, minced
1 tablespoon minced fresh sage leaves
1 teaspoon salt
1 teaspoon freshly ground black pepper
1/2 teaspoon ground nutmeg
4 medium red potatoes
2 large sweet potatoes, peeled
1 large rutabaga, peeled
6 ounces Gruyère cheese, finely grated
Preheat oven to 375 F. (190 C.) Butter a gratin dish.
Combine sour cream, garlic, sage, salt, pepper and nutmeg in a bowl and mix well. Thinly slice potatoes and rutabaga, preferably with a mandoline. Arrange 2 layers of red potatoes, overlapping, in bottom of gratin dish. Spread a thin layer of the sour cream over the potatoes. Sprinkle with a little Gruyere cheese. Cover with a double layer of sweet potatoes. Spread with a thin layer of sour cream and a sprinkling of Gruyere. Repeat with a layer of rutabaga. Repeat process until all of the vegetables have been incorporated. (There should be about 6 layers in all.) Thoroughly top gratin with remaining sour cream. Sprinkle a liberal amount of Gruyère over sour cream. Bake in oven until vegetables are tender and top of gratin is brown and bubbling, about 1 hour and 15 minutes. (Loosely cover gratin with buttered foil if browning too fast.) Serve garnished with fresh sage leaves.
