How to Make Lyonnaise Potatoes

  1. Preheat grill to medium heat.
  2. Wash and thoroughly dry 2 lbs of Yukon Gold potatoes. Pierce potatoes several times with a fork.
  3. Place potatoes directly on the preheated grill grates. Cook for 20 minutes, turning occasionally, until slightly softened.
  4. Loosely cover potatoes with foil and continue grilling for 25-35 minutes, or until tender and slightly caramelized.
  5. While potatoes are grilling, prepare the garlic: Caramelize 4 heads of garlic (see note below).
  6. Once potatoes are cool enough to handle, peel and slice them to 1/4 inch thickness.
  7. Melt 1/2 cup (1 stick) of unsalted butter in an oven-safe, grill-safe casserole dish.
  8. Add 1/4 cup of caramelized garlic to the melted butter.
  9. Thinly slice 1 large yellow onion.
  10. Layer potato and onion slices in the casserole dish, seasoning each layer with 1 tsp dried thyme, 1 tsp dried sage, a few dashes of Tabasco sauce, 1/4 tsp freshly grated nutmeg, and salt and pepper to taste.
  11. Pour 1 cup of hot chicken or vegetable stock over the potatoes and onions.
  12. Sprinkle 1/2 cup of grated Gruyère cheese (or similar) evenly over the top.
  13. Cover the casserole dish tightly with a lid or aluminum foil.
  14. Grill for 10 minutes with the grill lid down.
  15. Remove the lid/foil, close the grill lid, and cook for another 5 minutes, or until the cheese is melted and bubbly.
  16. Let rest for 5 minutes before serving.
