- Preheat your oven to 400°F (205°C). If using a grill, preheat to medium-high heat (about 400°F/205°C). If cooking on a campfire, prepare your campfire and let it burn down until you have a good bed of hot coals.
- Combine the thinly sliced potato, ¾ of a Reese glass caramelized onion, melted butter, thyme, and a little salt and pepper. Set aside.
- Place the pastry onto a large piece of baking paper. Lay neatly half the potato-onion mix, leaving a 1-inch (3 cm) border around the outside.
- Spread over half the cheese followed by the remaining potato mix.
- Top with the remaining cheese and the reserved caramelized onions.
- Fold the edges up and over the sides of the potato, brush with egg wash.
- Baking Options:
- Oven: Transfer to a baking tray and bake for approximately 35-40 minutes until golden brown.
- Grill: Transfer the galette on the baking paper onto a grill-safe baking sheet or a pizza stone. Close the grill lid and cook for approximately 35-40 minutes, checking occasionally to ensure it doesn’t burn. Adjust the heat as necessary.
- Campfire: Place the galette with the baking paper into a cast iron pan. Cover the pan with a lid or foil. Place the pan on the campfire grill or directly on the hot coals. Cook for approximately 35-40 minutes, rotating the pan occasionally to ensure even cooking. Check periodically to avoid burning and adjust the position as needed.
- When ready to serve, cut the tart into desired pieces.
Optional Topping: Combine the red onion, parsley leaves, a squeeze of lemon, splash of olive oil, and a little seasoning, serving this with the galette.
