Ingredients Equipment Method Notes

Ingredients
  

  • 3-4 tablespoons fresh thyme leaves
  • 2-3 cloves garlic, finely minced or grated
  • 1 heaping teaspoon kosher salt, plus more for seasoning between layers
  • Freshly cracked black pepper, to taste

Equipment

  • 9x5-inch metal loaf pan
  • Heavy-duty aluminum foil
  • Sharp mandoline slicer
  • Large bowl
  • Clean Kitchen Towels
  • Small bowl
  • Pastry brush
  • Baking sheet
  • Weights (e.g., cans of beans or a smaller loaf pan with pie weights)
  • Sharp chef's knife
  • Cutting board

Method
 

  1. Preheat oven to 400°F (200°C). Line a 9x5-inch loaf pan with a large sheet of heavy-duty foil, pressing into corners and leaving a generous overhang on all sides to create a sling. Generously butter the foil.
  2. Using a mandoline with the hand guard, slice the potatoes lengthwise into 1/16-inch thick planks. Immediately place slices in a large bowl of cold water to prevent browning and rinse off excess starch.
  3. In a small bowl, combine the melted butter, fresh thyme leaves, minced garlic, 1 teaspoon of kosher salt, and a generous amount of black pepper.
  4. Drain the potato slices and pat them thoroughly dry with clean kitchen towels. This step is crucial for achieving crispiness.
  5. Begin layering: Place a single, slightly overlapping layer of potato slices on the bottom of the prepared pan. Brush lightly with the thyme butter mixture. Repeat, brushing each layer, until all potatoes are used. Season lightly with a pinch of salt every few layers. Pour any remaining butter over the final top layer.
  6. Fold the foil overhangs over the top to create a tight parcel. Place the loaf pan on a baking sheet (to catch drips). Place a second, smaller loaf pan or a piece of parchment-lined cardboard cut to size directly on top of the foil-wrapped potatoes. Add weights (like cans of beans) on top to press down.
  7. Bake under weight for 1 hour and 15 minutes.
  8. Carefully remove the weights and top pan/cardboard. Unfold the foil from the top of the terrine. The potatoes will be cooked but pale. Brush the top with any remaining butter or pan juices.
  9. Return the terrine to the oven, uncovered, and bake for an additional 30-45 minutes, or until the top is a deep, golden brown and very crispy.
  10. Remove from oven and let the terrine rest in the pan for at least 30 minutes, ideally 1 hour. This allows the layers to set for clean slicing.
  11. Using the foil sling, carefully lift the entire terrine from the pan onto a cutting board. Slice into 1-inch thick slabs with a sharp chef's knife. Serve immediately, or reheat slices in a hot skillet with a little butter to re-crisp the sides.

Notes

For best results, ensure potatoes are patted completely dry before layering. If the terrine falls apart when slicing, it likely needed a longer rest. For a crispier bottom, place the loaf pan directly on the oven rack with the baking sheet on the rack below. MAKE AHEAD: Cook, cool completely, wrap in foil, and refrigerate for up to 2 days. Reheat slices on a rack in a 375°F oven for about 15 minutes until hot and crisp. VARIATIONS: Try rosemary instead of thyme, add grated Parmesan between layers, or substitute half the potatoes with sweet potatoes.
