Ingredients
4 small onions, thinly sliced
3 cup buttermilk
1 tablespoon olive oil
1 tablespoon unsalted butter
1 teaspoon coarse salt, plus more to taste
2 lb potatoes, such as Rose Gold, ALl Blue, and Swedish Peanut; cut to similar size
Freshly ground pepper
1 tablespoon dill, roughly chopped
Directions
Place potatoes in a medium saucepan, cover with cold water and add salt. Bring to a boil, and reduce to a simmer; cook until tender, 10 to 20 minutes. While potatoes cook, heat butter and oil in a medium skillet over high heat, and add onions. Reduce heat to medium, and saute until golden brown and slightly caramelized, 10 to 12 minutes. Heat buttermilk in a saucepan over medium low heat. Drain potatoes, and let cool briefly. Divide potatoes between soup bowls and pour 3/4 cup buttermilk into each bowl. Top with caramelized onions, season with salt and pepper and garnish with dill. Serves 4. From marthastewart.com
