Ingredients
- 1 kg Waxed potatoes (e.g., Yukon Gold or red potatoes) (Thinly sliced 2 mm; keep slices uniform for even cooking)
- 2 pieces Large onions (Thinly sliced; sprinkle with salt before cooking to draw out moisture)
- 4 tablespoons Unsalted butter (for clarification) (Clarify in microwave 20 seconds; skim off milk solids)
- 2 cups Beef stock (low‑sodium) (Used in layers to steam potatoes; can use homemade or store‑bought)
- 2 tablespoons Fresh thyme (Leaves picked and chopped; added between layers and on top)

- ½ teaspoon Freshly ground black pepper (Season each layer)
- 2 tablespoons Extra clarified butter (for finishing glaze) (Drizzled on top during final 5 min)
Instructions
Slice the potatoes
Using a mandolin with the guard on, slice the potatoes into uniform 2 mm rounds. If using a knife, cut as thinly and evenly as possible.
Time: PT10M
Caramelize the onions
Heat a splash of oil in the oven‑safe pan over medium‑low heat. Add the sliced onions, sprinkle with a pinch of salt, and cook, stirring occasionally, for 30–40 minutes until deep golden and sweet. Do not let them brown too quickly.
Time: PT40M
Clarify the butter
Place 4 Tbsp unsalted butter in a microwave‑safe bowl and microwave on high for 20 seconds. Let sit 10 seconds, then skim off the clear butter, leaving the milk solids behind.
Time: PT5M
Preheat the oven
Preheat the oven to 120 °C (250 °F).
Time: PT10M
Temperature: 120°C
Assemble the first layer
Spread a thin layer of the caramelized onions on the bottom of the pan. Drizzle 1 Tbsp clarified butter, add a splash (≈¼ cup) of beef stock, and season with a pinch of salt, pepper and a few thyme leaves.
Time: PT5M
Layer the potatoes
Arrange a single layer of potato slices over the onion‑butter mixture, overlapping slightly (smaller slices toward the centre, larger toward the edge). Drizzle another 1 Tbsp clarified butter, add about ¼ cup beef stock, and season with salt, pepper and thyme. Repeat the onion‑butter‑stock seasoning and potato layering until all potatoes are used, finishing with a top layer of potatoes.
Time: PT15M
Create the cartouche
Cut a piece of aluminum foil large enough to cover the pan, then cut a small central hole (≈2 cm) to allow steam to escape. Place a heat‑proof plate on top of the foil to keep the layers flat.
Time: PT5M
Low‑heat bake
Place the covered pan in the preheated oven and bake at 120 °C for 1 hour 45 minutes. This gently steams the potatoes while the stock and butter meld.
Time: PT1H45M
Temperature: 120°C
Remove cartouche & increase heat
After 1 h 45 min, remove the foil cartouche and plate. Increase oven temperature to 130 °C (265 °F) and bake an additional 25 minutes to caramelize the top.
Time: PT25M
Temperature: 130°C
Finish with glaze and thyme
Remove the pan from the oven. Drizzle the remaining 2 Tbsp clarified butter over any dry spots, add a splash of the reserved stock if needed, and scatter the remaining fresh thyme. Let rest 5 minutes before serving.
Time: PT5M

Troubleshooting
Potatoes are still firm after the low‑heat bake.
Continue baking at 120 °C, checking every 10 minutes until tender. Ensure enough stock was added to create steam.
Top layer burns or becomes too dark.
Reduce the final temperature to 125 °C or cover loosely with foil for the last 5 minutes.
Dish is watery.
Make sure excess stock is drained before the final high‑heat stage; you can also increase the final bake by 5‑10 minutes to evaporate excess liquid.
Storage
Refrigerator: Cool completely, then cover tightly and store for up to 3 days.
Freezer: Freeze in an airtight container for up to 1 month; reheat slowly in the oven to retain texture.
Room temperature: Not recommended; potatoes may become unsafe after 2 hours at room temperature.
Make-Ahead Tips
- Caramelize the onions a day ahead and store in the fridge.
- Clarify the butter in advance; keep the clarified butter in a sealed jar.
- Assemble the layered dish, cover, and refrigerate; bake directly from the fridge (add 10 minutes to bake time).

A frequent misconception is that the dish requires expensive French potatoes; in reality, any waxy British variety such as Yukon Gold or red potatoes works well.

What are the most common mistakes to avoid when making Best Pommes Boulangère (Layered Baked Potatoes) at home?
Avoid using overly thin potato slices, which can dry out, and be sure not to skip the clarification step for butter, as unclarified butter may cause soggy layers. Also, do not under‑season each layer; sprinkling salt and pepper between slices ensures balanced flavor throughout the bake.
Why does this Best Pommes Boulangère (Layered Baked Potatoes) recipe use clarified butter instead of regular unsalted butter?
Clarified butter has a higher smoke point and contains no water, allowing the potatoes to caramelise without steaming. This creates the signature glossy, golden crust while imparting a clean, buttery flavor that regular butter, with its milk solids, would not achieve.
How do I know when Best Pommes Boulangère (Layered Baked Potatoes) is done cooking?
The dish is ready when the top is deeply caramelised and slightly crisp, and a thin knife inserted into the centre meets little resistance, indicating the potatoes are tender. The edges should pull away from the dish easily, and the aroma should be buttery with a hint of thyme.
