Sable Boulangerie

Every once in a while a shop opens in the Phoenix area that makes you stop and ask, wait, that is here? Sable Boulangerie is one of those. A tiny walk up pastry and coffee shop tucked next to Liberty Market in Downtown Gilbert opened in mid May 2026 and the line out the door has not let up since.

I have driven over a few times. I gave up every time. The line was long. So this is a pre-review. If I cannot taste it yet, I might as well do the homework. So I spent some time reading up on the owner, the training, the flour (yes, the flour) and how this whole thing landed in Gilbert. Here is the story and why this place matters.

The owner is a Gilbert kid. William Porter grew up about 5 minutes from where the shop sits today. He went to Phoenix Country Day School and then attended Tufts University in Boston. And then did what very few Gilbert kids do. He moved to France. He enrolled at ENSP, a historic pastry school in Yssingeaux that operates out of a refurbished chateau (because in France, pastry school cannot just be a building. It has to be a castle). From there he went to Paris and worked under Cedric Grolet who is basically the LeBron James of modern French pastry. After Paris, he took a post inside the Burj Al Arab in Dubai, the hotel that mostly hosts royals and billionaires.

And then he came home to Gilbert.

That last part is the most interesting question to me. Why Gilbert and not Scottsdale or Arcadia or Uptown Phoenix where a fancy French pastry shop would be a slam dunk on the marketing side? Porter is pretty open about it. Pastry, the way he wants to do it, is what he calls a grind business. It is a middle of the night, on your feet, no shortcuts kind of job. And to do that for years on end, you need family, friends and a community around you. So he came back to the place that raised him. There is something heartwarming about that.

A small note for the curious. The shop is named Sable Boulangerie, but the legal and web identity is Maison William Porter. In French pastry land, "Maison" is loaded. Think Maison Pierre Herme or Maison Cedric Grolet. It signals a chef-driven house and not a regular bakery. Porter trained under Grolet, whose own brand uses the same structure. So this is him quietly telling you what standard he wants to be measured against. Which is to say, do not walk in expecting a Paris Baguette (no offense to PB).

Now the nerdy part because I cannot help myself. Every bag of flour at Sable comes from a single mill in France called Antoine. Porter says the flour had never been imported into the United States before. He had to deal with FDA labels, customs paperwork and the joy of waiting for a shipping container to fill up before the boat could even leave port. He and his team then ran somewhere between 24 and 30 dough tests in Gilbert to re-tune the recipe for American eggs, Arizona humidity (or lack of rather) and the citric acid that apparently shows up in our domestic whole egg products. That is a level of fuss most bakeries would never bother with. It is also the kind of detail that tells you a lot about Porter's operation before you even taste anything!

The shop itself is tiny. Porter calls it a pastry lab rather than a kitchen. He runs it with one other person. Dough is mixed, laminated, shaped, proofed and baked in the same overnight cycle. By 8AM the croissants are coming out of the oven. The menu is small on purpose. Porter has said the pain au chocolat is his signature, not the croissant. He considers it the hardest pastry he makes. He has strong opinions about American versions of it (under proofed, meaty centers, peeling exteriors) and is openly trying to change minds.

A small note since this is, in theory, a craft coffee website. The coffee menu at Sable is tiny for now. Latte, Latte Vanille, Latte Pistache, Latte Hazelnut and a Paris Hot Chocolate. That is five drinks. If you order coffee by elevation and processing method, take a deep breath. But the place is very new. I am betting the menu grows in the future. Until then, I will be over there ordering a Latte Pistache once I get past the line.

So why am I writing about a place I have not eaten at yet? Because the story is already cool and because you should know what is sitting next to the water tower in old town Gilbert the next time you are out there. I am going to wait a few weeks for the early hype line to cool down then go back and actually try the coffee and the pastries.

A real review may follow. Or maybe not. Though honestly, with a resume like that (flour imported from a single French mill, recipes re-calibrated for American eggs and Arizona humidity, dough tested 30 different ways) the math checks out. The pastries are almost certainly going to be out of this world.

For now, all I can tell you is this. A Gilbert kid trained in a French castle and worked for one of the most famous pastry chefs alive then did a tour at the Burj Al Arab and came back home to bake croissants for his neighbors. Gilbert just got a very fancy tenant and a zip code upgrade.
