Ingredients

  • Rack of lamb: about 1.5 to 2 pounds (700-900g), frenched
  • Fresh rosemary: 2 tablespoons, finely chopped
  • Fresh thyme: 1 tablespoon, finely chopped
  • Fresh parsley: 2 tablespoons, finely chopped
  • Garlic: 3 cloves, minced
  • Dijon mustard: 2 tablespoons
  • Olive oil: 2 tablespoons
  • Salt and freshly ground black pepper: to taste
  • Yukon Gold potatoes: 2 pounds (900g), peeled and thinly sliced (about 1/8 inch or 3mm thick)
  • Heavy cream: 2 cups (480ml)
  • Milk: 1 cup (240ml)
  • Garlic: 3 cloves, crushed
  • Unsalted butter: 2 tablespoons, softened
  • Grated Gruyère cheese: 1 cup (100g) (optional)
  • Fresh nutmeg: a pinch, grated (optional)

Instructions

  1. Preheat your oven to 400°F (200°C).
  2. Pat the rack of lamb dry with paper towels. Season generously with salt and pepper on all sides. Trim excess fat if needed.
  3. In a small bowl, combine chopped rosemary, thyme, parsley, minced garlic, olive oil, and Dijon mustard until it forms a paste.
  4. Heat your skillet over medium-high heat. Once hot, add the lamb rack, fat side down, searing for 2-3 minutes until golden brown. Turn to sear the other sides briefly.
  5. Remove the pan from heat. Spread the herb mixture evenly over the fat side of the lamb rack.
  6. Transfer the skillet or pan to the oven. Roast for 15-20 minutes for medium-rare (internal temp ~130°F/54°C). Let rest covered loosely with foil for 10 minutes before slicing.
  7. While the lamb roasts, combine the cream, milk, crushed garlic, salt, pepper, and a pinch of nutmeg in a saucepan. Warm gently over low heat for about 5 minutes without boiling.
  8. Butter your baking dish. Arrange a layer of sliced potatoes, overlapping slightly. Pour a bit of the warm cream mixture over them. Repeat layers until all potatoes are used, ending with cream on top.
  9. Sprinkle grated Gruyère evenly over the top layer (optional).
  10. Bake the dauphinoise uncovered in the oven for about 50-60 minutes until potatoes are tender and the top is golden brown and bubbling.
  11. Once the lamb has rested, slice between the ribs into individual chops. Serve immediately with a generous spoonful of garlic dauphinoise.

Notes

Let lamb rest at room temperature for 30 minutes before cooking. Use a meat thermometer to ensure medium-rare at 130°F (54°C). Thin, uniform potato slices ensure even cooking. Warm cream gently to infuse garlic without boiling. Rest dauphinoise 10 minutes after baking. Cover dauphinoise loosely with foil if browning too fast. Dairy-free substitutions include coconut cream and dairy-free margarine; omit cheese or use non-dairy cheese.
