Ingredients
For the shell
  • 2 large (about 1 1/2 pounds) Russet potatoes, peeled, shredded, rinsed and drained (press out all excess in strainer)
  • Salt and pepper
  • A few grates nutmeg
  • 1 rounded tablespoon Dijon mustard
  • 4 tablespoons melted butter
For the filling
  • A fat drizzle EVOO – Extra Virgin Olive Oil
  • 4 slices meaty bacon, chopped or cut into lardons (1/4-inch sticks)
  • 1 large onion, finely chopped
  • 1 tablespoon finely chopped fresh thyme or 1 teaspoon dried thyme
  • 2 cloves garlic, chopped
  • 6 eggs
  • 1/2 cup half-n-half or cream
  • 6 ounces (about 1 1/2 cups) shredded Gruyère
Preparation

Preheat oven to 400°F.
 
In a bowl, combine potatoes with salt, pepper, nutmeg and Dijon. Brush a 10-inch glass or ceramic pie plate, or an oven-safe, nonstick skillet or tart pan liberally with about 2 tablespoons butter. Line the pan evenly with potatoes to form a crust to the edge of the pan—tuck in any straggling bits of potatoes as they will burn. Brush the top of potato crust with remaining melted butter and bake about 30 minutes to golden; let cool.

 
Meanwhile, heat a skillet over medium-high heat with a drizzle of EVOO. When it ripples, add bacon and render 3 minutes, stirring frequently. Add onions, thyme, garlic, salt and pepper, and reduce heat a bit. Cook to soften, 12-15 minutes.
 
Whisk up eggs and cream then add onions and bacon and mix to combine. Pour filling into the potato crust and bake 15 minutes. Remove from oven, top with cheese and return to oven to bake 12-15 minutes more until brown and bubbly.
 
Serve warm or room temperature with a salad dressed with Dijon or lemon vinaigrette alongside.
