The bread and pastries are delicious, and the staff are super friendly. The heated ham & cheese croissant is the best I’ve ever had—it’s a bit pricey but definitely worth trying. The iced latte and mocha are also great.I rarely ate sourdough before, but now I find myself visiting this place twice a month!

About and visit notes
For Arizona residents seeking truly exceptional baked goods that combine ancient traditions with local ingredients, look no further than Proof Bread. Located conveniently in the vibrant heart of Downtown Phoenix, this establishment is more than just a bakery—it's an artisan sourdough operation and a working flour mill dedicated to producing bread and pastries of unparalleled quality. Proof Bread’s philosophy is rooted in long fermentation, using only natural sourdough starter (affectionately named 'Harriet') for every single product, resulting in food that is not only delicious but also more easily digestible and nutritious.
Proof Bread has quickly earned a reputation across the Valley of the Sun for taking the sourdough process to its absolute extreme. They offer a comprehensive menu that spans from classic Country Sourdough loaves to highly sought-after, complex pastries like the Sourdough Croissant and Ham & Cheese Croissant. Their commitment to superior ingredients is exemplified by the operation of the Proof Flour Mill, where they stone-mill heritage and ancient grains, often sourced from local Arizona farmers, right in-house. This farm-to-table ethos ensures maximum freshness and supports local agriculture, a feature highly valued by the Arizona community. Whether you are a lifelong sourdough fan or, like one customer, someone who "rarely ate sourdough before" but now visits twice a month, Proof Bread offers a unique, quality-focused culinary experience right here in Phoenix.
Introduction / Overview
Proof Bread is an all-sourdough commercial bakery and flour mill based in the Phoenix Metro area, with a flagship location that serves the Downtown Phoenix community. They specialize in naturally leavened bread, pastries, and even Roman-style pizza, with every item on the menu being fermented using their traditional sourdough starter. The business prides itself on its "modern throwback" approach, utilizing time, dedication, and the best available ingredients—particularly house-milled heritage grains—to create products that honor baking history.
Their product range is extensive and deeply rooted in quality. From the hearty Sprouted Multigrain and Khorasan Sourdough loaves to their famous 81-layer laminated sourdough croissants and Danishes, the menu is a testament to the versatility of the sourdough process. The Downtown Phoenix location is a perfect spot for locals to grab a sophisticated breakfast, enjoy a sourdough pizza lunch after 10:30a, or simply stop in for a meticulously crafted coffee featuring local Press Coffee, all while enjoying a welcoming and communal atmosphere.

What is Worth Choosing
Proof Bread is worth choosing for the Arizona consumer who is done compromising on the quality of their staples.

Nutritious bread and the most delicious pastries. Love the specialty items Proof introduces as well, they are always worth trying!
May 26 · David FloresNothing says “celebrating my diet progress” quite like… undoing it entirely at Proof Bread Co’s new downtown spot. I told myself I was just swinging by for one loaf of bread. You know, casual, responsible, just a little treat.Cut to: me walking out with three loaves, four chocolate chip cookies, and a pepperoni pizza. Honestly? Zero regrets.The place itself is adorable and super convenient like the kind of spot that makes you want to “accidentally” forget your lunch just so you have an excuse to stop in. The smells hit you like a carb-loaded hug the second you walk in, and the girl at the counter was so nice she could’ve sold me a sourdough starter and told me to name it.10/10 would sacrifice abs for bread again.
Aug 17 · Christopher OwensDelicious pastries, strong coffee, dog friendly, indoor and outdoor seating. So thankful Proof has a downtown location!!
May 26 · Harlene GabianaProof's spot on Roosevelt is utterly fabulous. Stop in for one of their fresh pastries, get a tasty coffee to go with it, and grab a delicious loaf of bread for dinner that night. There is cute indoor seating space and a wide open walk-up window with patio.Plus the people there are always so friendly and willing to answer questions about their bread or just help start your day on a lighter note.They're an amazing addition to this part of Roosevelt and I highly recommend a stop.
