1. Parboil the potatoes in salted water for 8–10 minutes until just tender; drain and chill until cold (at least 30 minutes) then grate coarsely and squeeze out excess moisture in a clean towel. 2. In a large skillet, heat 1 tbsp (15 ml) neutral oil over medium-high heat. Add the grated potatoes, press into a compact cake, reduce heat to medium-low and brown undisturbed 8–10 minutes until a deep golden crust forms; flip in sections, add 1 tbsp (15 ml) butter and cook another 6–8 minutes. Keep warm. 3. Meanwhile, in another skillet over medium heat, melt 2 tbsp (30 ml) butter with 1 tbsp (15 ml) olive oil. Add the sliced onion and 1/4 tsp (1 g) salt; cook slowly, stirring occasionally, until deeply golden and caramelized, about 20–25 minutes. Deglaze with the white wine if using and simmer until liquid evaporates; keep warm. 4. Pat the sausages dry. In a clean heavy skillet, add 1 tbsp (15 ml) olive oil and heat to medium. Sear sausages, turning occasionally, until evenly browned and cooked through (internal temperature 160°F/71°C), about 12–15 minutes. If sausages are thick, finish covered over low heat 6–8 minutes. 5. Remove sausages and let rest 5 minutes. Slice sausages on the bias or serve whole atop pieces of rösti, spoon caramelized onions alongside, and finish with a dollop of Dijon mustard and chopped parsley. 6. Adjust seasoning and serve immediately while hot; accompany with pickles or a simple green salad if desired.
