French Egg-Yolk Christmas Sablés Recipe
Follow the tray sizes, portions and baking intervals in the instructions below.
Total time includes hands-on preparation, required chilling or resting, whole-batch cooking, cooling and finishing.
Kitchen tools you’ll need
- mixing bowl
- mixer
- kitchen scale
- two 13 x 18-inch half sheets
- parchment
- pastry brush
- fork
- wide spatula
- cooling rack
Ingredients
US measures are approximate. Gram weights help keep portions consistent; spice weights vary with density.
Instructions
Mix the dough
- Mix the dough: Beat butter and sugar until smooth. Add one yolk (18 g), vanilla and salt, then flour; mix just until the clumps hold.
Shape and manage temperature
- Shape and manage temperature: Divide into 24 equal portions, about 16 g excluding wash. Flatten between parchment to 2-inch rounds, 1/4 inch thick. Chill 45 minutes. Stir the second yolk with water, brush thinly on the tops and draw shallow crosshatching with a fork.
Bake the whole batch
- Bake the whole batch: Heat oven to 350°F (175°C) conventional or 325°F (165°C) fan. Arrange cookies on two parchment-lined 13 x 18-inch half sheets, 12 cookies per tray, with at least 1 inch between edges. Bake one tray at a time on the middle rack, keeping the waiting tray refrigerated for 16–20 minutes, rotating front to back once, until the edges and bases are lightly golden and the centers look dry. Whole-batch cookie baking is 2 trays x up to 20 minutes = 40 minutes.
Cool and finish
- Cool and finish: Rest 10 minutes on each tray, then cool 20 minutes on a rack before serving or packing. Cooling includes the tray rest.
Timing and scaling
- Timing and scaling: Active preparation is 30 minutes; required chill/rest is 45 minutes; whole-batch oven baking is 40 minutes; cooling/setting is 30 minutes. Cooling allowance runs from the final tray; earlier trays may cool during later baking and that overlap is not counted again. Start with butter at the stated consistency; ingredient warm-up and frozen-dough thawing are extra. Oven preheating can overlap shaping or chilling. Scale every ingredient weight but keep piece dimensions, oven temperature and per-tray bake range unchanged; extra trays increase whole-batch time.
Chef’s Science & Pro Tips
Ingredient science
The dough yolk supplies emulsifier and water for a cohesive yet sandy sablé.
Technique & texture
Keep the wash on the top; pooled yolk around the base makes a dark rim.
Finishing & serving
Scratch the surface lightly after brushing so the crosshatching stays decorative rather than splitting the cookie.
Storage and make-ahead
| Method | How long | What to do |
|---|---|---|
| Room temperature | 5 days | Up to 5 days. Store completely cooled cookies airtight in a cool, dry room, with parchment between layers. Keep away from moist filled cookies. |
| Refrigeration | up to 7 days | Unnecessary; up to 7 days if needed. Baked refrigeration is unnecessary for these unfilled cookies and may soften the crumb. If the room is warm, seal airtight and bring to room temperature while still covered. |
| Raw freezing | 1 month | Up to 1 month. Freeze wrapped dough or unbaked portions airtight. Thaw covered overnight in the refrigerator; shape as directed, then complete any stated post-shaping chill. Do not add thaw time to the fresh-batch timings. |
| Baked freezing | 2 months | Up to 2 months. Freeze fully cooled cookies airtight with parchment between layers. Thaw in their sealed container at room temperature for about 1–2 hours. |
| Restoring | As described | Serve after thawing; optional 3–5-minute refresh. For plain unfilled cookies only, refresh at 300°F (150°C) conventional or 275°F (135°C) fan for 3–5 minutes, then cool 20 minutes before sealing. This is extra time beyond the fresh recipe. |
Notes
- Scale ingredients, including US measures, without changing cookie size or oven temperature. Extra trays increase whole-batch time.

Frequently Asked Questions
Do both yolks go into the dough?
No; one 18 g yolk goes into the dough and the second makes the top wash with 5 g water.
Why use superfine sugar?
Its small crystals disperse in this briefly mixed dough and keep the thin sablé smooth.
Can I brush before chilling?
Brush after the 45-minute chill so the firm tops hold the fork pattern.
