These are the BEST gluten-free sourdough hamburger buns—soft, fluffy, vegan, and nut-free. Packed with wholesome ingredients like rice flour and psyllium husk, they’re a game-changer for any burger night. Whether you’re craving classic cheeseburgers or veggie patties, these homemade burger buns are the perfect vessel.

For years, I’ve dreamed of a perfectly soft, spongy, a little chewy, and beautifully golden gluten-free burger bun. Gluten-free buns at restaurants tend to be so dry and crumbly that it makes the whole burger-eating process a bit of a fiasco. Definitely not the ultra-satisfying experience you crave when you order a burger. So, it was about time this recipe landed on our tables: gluten-free sourdough burger buns.

They’re everything you want in a hamburger bun, and more:

  • Soft and spongy with an open crumb
  • Durable enough to hold up to your loaded burger
  • Will not fall apart at the touch of a sauce
  • Topped with sesame seeds for the classic look
  • Easy to adjust the size – sliders, anyone?
  • A little tang from the sourdough for extra flavor
  • Simple to make from scratch!
  • No eggs and no xanthan gum needed.

As with everything sourdough, these sourdough burger buns do require forethought to be ready for your burger night, but the preparation is absolutely worth the result. They also freeze incredibly well, so you can bake, slice, and store for future burger nights on a whim.

How to make gluten-free sourdough buns

1. Make the Psyllium Gel

Whisk milk, water, and psyllium husk in a large bowl. Add honey and olive oil. Mix until thick and jelly-like.

2. Mix the Dough

In another bowl, whisk rice flour, tapioca starch (aka tapioca flour), potato starch, and salt. Add the psyllium gel and sourdough starter. Mix until smooth, soft, and slightly sticky.

3. Shape & Weigh

Divide the dough ball into eight equal pieces (~130 g each). Roll into smooth rounds and place on a parchment-lined tray.

4. Ferment

Cover and place in the refrigerator for 8–12 hours. The next day, keep the buns covered and let them sit at room temperature for 2 hours, until they are slightly puffed.

5. Preheat & Prep

Preheat oven to 400°F (200°C). Brush buns with water and sprinkle with sesame seeds. You can use an egg wash instead of water if you’re not vegan and want an extra shiny top.

6. Bake

Place the burger buns in the oven and immediately lower the temperature to 375°F (190°C). Bake 30 minutes, until golden and firm. Brush with melted butter and cool on a wire rack before slicing.

Prepare your gluten-free sourdough hamburger buns ahead of time

Make-ahead dough: After shaping the buns, you can refrigerate them (covered) overnight. Bring back to room temperature and finish proofing before baking.

Short-term storage: Once cooled, store your burger buns in an airtight container or freezer bag at room temperature for up to 2 days.

Freeze for later: Slice the buns in half before freezing—this makes it easy to toast them straight from the freezer. Store in a freezer-safe bag or an airtight container for up to 2 months.

Reheating: Warm in the oven at 300°F (150°C) for 8–10 minutes for a soft bun, or toast for crispy edges.

  • 320 g potato starch
  • 8 g fine sea salt

Instructions

  • Divide the dough into 8 equal portions, about 130g each. Gently roll each piece into a round, smooth bun and place them on a parchment-lined tray.
  • Cover and refrigerate overnight (8–12 hours). The next day, remove from the fridge and let the buns sit at room temperature for 2 hours, until slightly puffed.
  • While the buns come to room temperature, preheat the oven to 400°F (200°C). Once the oven is hot, brush the buns with water with a pastry brush and sprinkle generously with sesame seeds for a beautiful crust. You can use an egg wash instead of water if you’re not vegan and want an extra shiny top.
