Hi there! I’m Cassandre. Today on Caramel Loafing, I’m sharing a simple yet timeless French butter cookie: Sablés Nantais, also known as French Nantes Shortbread.
This crisp, buttery cookie comes from Nantes, a port city in western France famous for its rich, butter-based pastries. Historically, Nantes was a major hub for the sugar and spirits trade, inspiring local treats like the beloved Nantais Cake and these deliciously crisp Sablés Nantais.
If you’ve made our Breton Shortbread before, this recipe will feel familiar. The biggest difference is that Sablés Nantais are thinner, larger in diameter, and hold their round shape without using a pastry ring. They’re wonderfully crisp, buttery, and have a hint of salt that makes them almost impossible to stop eating.
Did you know that the famous Japanese butter cookie souvenir, Échiré Maison DU Beurre, has a best-selling cookie inspired by Sablés Nantais (they’re called 『サブレ ナンテ』 in Japanese). Now you can make them yourself — no long lines in Japan required.
Cookies like these bring a quiet bit of everyday happiness to any moment — with afternoon tea, a quick snack, or a simple treat to share. Sablés Nantais are just that kind of cookie: easy to make, easy to store, and beautifully balanced in flavor. I’ll share a few tips too, so you can bake this classic French cookie right at home.
Once you master sablé dough, you’ll love trying other recipes like: Diamond Sablé Cookies, Jam-Filled Sablé Cookies, or a French Blueberry Tart (which uses a classic sablé crust).
You’ll probably also love these other French treats: French Almond Tuiles, Langues de Chat (French Cat Tongue Cookies), and Florentine Toffee Nut Cookies.

How to Make Sablés Nantais
- Scrape the vanilla seeds into the beaten egg; add the salt and mix until fully dissolved. Set aside.
- Line a baking sheet with parchment paper or a silicone baking mat.
- Sift the flour, powdered sugar, and baking powder together; transfer to a food processor and pulse briefly to combine.
- Add the chilled butter and pulse until the mixture resembles coarse crumbs. Pour in the vanilla egg mixture and pulse just until a dough forms.
- On a work surface, gently press and smear the dough with the heel of your hand (fraisage technique) to help it come together smoothly; repeat 1–2 times, then wrap in plastic wrap and chill for 1 hour.
- Prepare the egg wash: dissolve 2 g instant coffee in 8 g hot water; stir well. Add 2.5 g of the coffee mixture to 15 g beaten egg and mix thoroughly. (Use the minimum amount of water needed to dissolve your brand of instant coffee.)
- Roll the dough to about 1/6 inch (4 mm) thick. Use a 2.75-inch (7 cm) round cutter to cut out 12 cookies.
- Place the cookies on the prepared baking sheet, spacing them about 1/2–3/4 inch (1–2 cm) apart. Brush with a thin layer of coffee egg wash; chill for 20 minutes to allow the surface to dry.
- Brush a second thin layer of egg wash and score decorative lines with a fork.
- Preheat the oven to 355°F (180°C). Bake for 22–23 minutes, until the tops are evenly golden brown.
- Cool on a wire rack. Once fully cooled, store in an airtight container in a cool, dry place below 68°F (20°C), or refrigerate if your kitchen is warm.

Sablés Nantais FAQ & Tips
Sablés Nantais may look simple, but they’re full of small details that make all the difference. Here are answers to the most common questions to help you achieve perfectly crisp, buttery cookies every time.
Why must the butter be cold?
This is a sablé-style dough, so chilled butter is essential to create that delicate, sandy texture. Soft butter will compromise the crumb and cause the cookies to spread or lose their defined edges during baking.
Can I make sablé dough by hand?
Yes, absolutely. We’ve shared sablé recipes using both a food processor and the traditional hand-rubbed method.
There are two common techniques: the cut-in method (rubbing cold butter into dry ingredients until sandy, then adding the egg) and the creaming method (creaming softened butter and sugar, then incorporating the egg before adding flour). For the hand-rubbed method, check our Jam-Filled Sablé Cookies. For the creaming method, see our Breton Shortbread Recipe Video. Both methods work beautifully—use whichever suits your style.
How do I make the coffee egg wash?
The coffee egg wash gives these cookies their beautiful golden color and a subtle roasted aroma. Different brands of instant coffee dissolve differently, so use the minimum amount of water needed to achieve a concentrated flavor and rich color.
Brush in two thin coats: chill the first layer for about 20 minutes to let it dry completely, then brush the second coat and score the surface. This creates a smooth, even finish. Applying too much egg wash at once may cause cracking or uneven baking.
Any tips for the surface pattern?
Use a fork to gently score a crosshatch or sunburst pattern—a classic look for Sablés Nantais. This not only enhances appearance but also helps the egg wash bake evenly and prevents surface bubbles. It can also help control slight surface expansion during baking.
What’s the best thickness and cutter size?
Roll the dough to about 1/6 inch (4 mm) thick for the best balance of crispness and structure. Too thick and the cookies won’t be as crisp; too thin and they may brown too quickly. A 2.75–3 inch (7–8 cm) round cutter works well. Leave at least 1/2 inch (1 cm) between cookies on the baking sheet.
How should I store these cookies?
Let the cookies cool completely, then store them in an airtight container in a cool, dry place below 68°F (20°C). If your kitchen runs warm, refrigerate instead. If they soften over time, refresh them in a low oven for a few minutes—they’ll taste freshly baked again.
