Sourdough Discard Hamburger Buns with Fresh Milled Flour

Learn how to make your own homemade hamburger buns with fresh milled flour and your sourdough discard! This recipe creates hamburger buns that are light and buttery, with just a hint of sourdough tang. Not only do you save yourself a trip to the grocery store, but you will also be saving nutrients when you use fresh milled flour to make these hamburger buns.

My kids love these sourdough discard buns. We use them for hamburgers, pulled pork, or deli sandwiches and they are always a hit.

Fresh milled flour offers benefits that traditional all purpose flour does not. It not only gives your bread more nutrients, but also more flavor! Add in the fact that this uses sourdough discard, you get a unique, but delicious, flavor for your hamburger buns.

Why Use Fresh Milled Flour for Hamburger Buns (and Why I Love Hard White Wheat)

If you’ve been around here a while, you know I’m a big fan of using fresh milled flour in my baking and these sourdough discard hamburger buns are no exception. There’s just something special about milling your own wheat berries and knowing exactly what’s going into your food. When you use fresh flour, you’re keeping all those naturally occurring oils, vitamins, and minerals intact. That means more flavor, better texture, and nutrients that haven’t been sitting on a shelf for months.

For this recipe, I love using hard white wheat. It’s one of my go to grains because it’s light in color and flavor, but still has enough protein and gluten strength to make soft, fluffy sandwich or burger buns. It is the perfect middle ground, not as heavy as hard red wheat, but more structure than soft white. The result? Buns that hold together beautifully without being dense or dry.

If you’ve been looking for a way to bring the benefits of whole grains into your baking without giving up that soft, bakery-style texture, hard white wheat will be your new best friend. Once you try it fresh milled, you’ll never want to go back to store-bought flour again.

Tips for Milling & Storing Wheat Berries to Create Fresh Milled Flour

If you’re new to fresh milling, it can feel a little intimidating at first. Once you get the hang of it, it becomes second nature! Here are a few simple tips to help you get the best results every time:

1. Mill right before baking.
Freshly milled flour is at its peak in flavor and nutrition right after grinding. The natural oils in the wheat start to oxidize once exposed to air, so I always mill only what I need for the recipe I’m making that day.

2. Store your wheat berries, not your flour.
Wheat berries have a long shelf life (often years!) if stored properly. Keep them in an airtight container in a cool, dark place. I like using 5-gallon buckets or glass jars with gamma lids. This keeps out moisture and pests and preserves freshness. You can learn more about storing wheat berries and where to buy them here.

3. Check your settings.
If your mill has adjustable settings, use a finer grind for things like buns, cookies, and cakes, and a slightly coarser grind for hearty breads. Hard white wheat mills beautifully into a fine flour that’s perfect for soft, fluffy baked goods.

4. Rotate your stock.
Just like pantry staples, use the “first in, first out” method. Label your buckets or jars with the purchase date so you’re always using the oldest grains first.

Fresh milling really is one of those small switches that makes a big difference. Not only does it give your baking more depth and nutrition, but there’s also something so satisfying about the process.

Ingredients for Fresh Milled Flour Buns with Sourdough Discard

• Milk – I use whole milk because the natural fat helps to give the buns a richer and softer texture versus when you use low fat milk. It also helps the dough brown in the oven.
• Instant dry yeast – I like using Bob’s Red Mill for a reliable rise. A little yeast in this sourdough recipe helps to speed up the rise time and make the buns fluffy. It’s important to use fresh, active yeast (ideally no older than 6 months after opening) so your dough rises properly. Old or expired yeast can lose its strength and leave your buns dense instead of soft and fluffy.
• Honey – We use raw, unfiltered honey so that it is less processed. Plus, the honey helps to feed the yeast.
• Butter – Always use real butter (unless you’re needing it to be dairy free). This helps to create tender and soft buns.
• Egg – This helps to emulsify the dough, giving you a smooth, soft texture for your buns.
• Sourdough discard – This brings the extra tangy flavor and helps the buns rise a little. If you’re new to sourdough, you can learn to make your own starter here.
• Fresh-milled hard white flour – I mill my own hard white wheat berries because it gives the best balance of softness and structure. Hard white has enough protein to hold shape (without getting dense like hard red) and a lighter color and flavor that makes the buns taste more like classic bakery-style rolls. Using soft white wheat can make them too delicate, while hard red can make them darker and heavier.
• Salt – I like using Redmond Real Salt for the trace minerals.
• Egg wash: 1 egg yolk + 1 tablespoon water (brush for shine)

FAQ: Sourdough Discard Hamburger Buns Made With Fresh Milled Flour

Can I make these buns without yeast?
You can, but they’ll take longer to rise. The sourdough discard gives flavor, but it’s not strong enough to lift the dough on its own unless it’s very active. I like using a little yeast for a faster, more reliable rise while still getting that sourdough goodness.

What kind of wheat works best for hamburger buns?
I use hard white wheat for most of my sandwich and burger buns. It makes them soft, fluffy, and light in color, not heavy like hard red wheat can be. It’s perfect for recipes where you want a tender crumb but still the nutrition of whole grains.

Do I need to let the dough rise twice?
Nope! This recipe is a one-rise dough. After mixing and kneading, you shape the buns, let them rise for about an hour until puffy, and then bake. It’s simple and still gives great texture.

My dough feels sticky — what should I do?
Fresh milled flour can soak up liquid a little differently every time. If the dough feels sticky before kneading, let it sit for about 10 minutes to give the flour time to absorb the liquid. It usually evens out on its own.

If it’s still sticky after kneading, then add a little more flour, one tablespoon at a time, until it feels soft and just slightly tacky but easy to handle.

Can I freeze these buns?
Yes! Once baked and cooled, freeze them in a freezer-safe bag. When you’re ready to use them, let them thaw at room temp or warm them up in the oven for a few minutes. They taste just as good as fresh!

Steps to Make Hamburger Buns

1. Activate yeast: In a medium bowl combine warm milk (≈95–105°F / 35–40°C), yeast, and honey. Stir and let sit 3–5 minutes until yeast looks bubbly or slightly foamy.
2. Mix wet ingredients: Add the melted butter, beaten egg, and sourdough discard to the milk mixture; mix to combine.
3. Combine dry: In a large bowl whisk together the fresh-milled hard white flour and salt.
4. Make the dough: Pour wet into dry and mix with a wooden spoon or paddle until a shaggy dough forms. If it’s very dry, add 1 tablespoon water at a time (up to 2 tbsp) until it comes together. Turn onto a lightly floured surface and knead by hand 8–10 minutes until smooth and elastic (or 6–8 minutes in a stand mixer on medium-low). The dough should be soft, slightly tacky, and not rock-hard.
5. Shape right away: Divide the dough into 8 equal pieces. Shape each into a tight round and flatten slightly into a bun shape. Place on a parchment-lined baking sheet about 2 inches apart.
6. Rise: Cover with a clean towel or lightly greased plastic wrap and let rise in a warm spot for about 1 hour, or until puffy and nearly doubled.
7. Preheat oven: While the buns rise, preheat the oven to 375°F (190°C).
8. Finish & bake: Brush the tops with egg wash and sprinkle sesame seeds if desired. Bake for 14–18 minutes, until golden brown and the centers register about 190–200°F (88–93°C).
9. Cool: Remove from pan and cool on a rack for at least 15 minutes before slicing.

Tips & variations

• Adjust for fresh-milled: If your dough seems gummy later in knead or proof, sprinkle very small amounts of flour (1 tbsp at a time). If dry, add water 1 tbsp at a time. Freshly milled flour varies — trust feel over measurements.
• Make milkless: You can try using water + 1 tbsp butter (or oil) if you want dairy-free, but it may change how these buns turn out.
• Eggless wash: Brush with milk or a mix of milk + maple syrup for color.
• Make ahead: After shaping, you can refrigerate the tray overnight (covered) and bake the next morning. Just add ~5–10 minutes to bake time if baking cold.
• Freezing: Bake, cool, then freeze. Toast or reheat in oven to refresh.
