A beloved staple in French bistro cuisine, this dish shines with premium cooked sausage—opt for pistachio-studded if available. As an expert in regional French recipes, I've perfected this Lyonnais classic for authentic flavor and simplicity.
Difficulty: Easy (2/5)
Wash the potatoes without peeling and place in a saucepan. Cover generously with cold water, salt generously, and bring to a boil. Cook for about 25 minutes until tender.
Meanwhile, place the sausage(s) in another pan—no need to prick. Add 2 liters of cold water and lightly salt. Bring to a boil, then simmer for 30 minutes. Peel and finely chop the shallots; chop the chives.
Whisk a well-seasoned vinaigrette: 4 tablespoons oil, 2 tablespoons white wine vinegar, a pinch of Dijon mustard, salt, and pepper.
Drain the potatoes, rub off skins in a tea towel, and slice thickly into a salad bowl. Sprinkle immediately with 1-2 tablespoons white wine. Add shallots, toss, and let cool slightly.
Drain the sausage(s), remove skin, and slice into thick rounds. Plate the potatoes, top with sausage slices, drizzle with vinaigrette, and sprinkle with chives. Finish with fresh pepper and serve warm.
Alternatively, pair the hot sausage with steamed potatoes and fresh butter for a rustic twist.
