Sourdough Hamburger Buns: Soft, Sturdy, Beautiful

Short answer: make slightly enriched sourdough buns at 65% hydration with milk, butter, and egg. Shape into balls, proof, top with sesame seeds, and bake at 400°F. They're soft enough to bite cleanly but sturdy enough for a quarter-pounder.

The recipe

For 8 hamburger buns:

• 500g bread flour
• 280g milk
• 100g active starter
• 30g sugar
• 50g butter, softened
• 1 large egg
• 8g salt

For topping:

• 1 egg + 1 tbsp water (egg wash)
• Sesame seeds (or poppy, or everything seasoning)

Method

Mix

Combine milk, starter, sugar, egg, salt. Mix.

Add flour. Mix to shaggy.

Add softened butter. Knead 8–10 min until smooth and elastic.

Bulk

4–6 hours at 75°F until dough rises 50%.

Divide and shape

Divide into 8 equal pieces (~115g each).

Shape into tight balls.

Pan

Place on parchment-lined sheet pan, 4cm apart.

Final proof

1.5–2 hours at 75°F until visibly puffy.

Bake

Preheat to 400°F.

Brush with egg wash. Sprinkle sesame seeds.

Bake 18–22 min until golden brown.

Cool fully on rack before slicing.

Why these are perfect for burgers

A real hamburger bun:

• Soft enough to bite cleanly
• Strong enough to hold the burger
• Slightly sweet
• Toasted at the seams (when you slice and grill)

This recipe nails all four.

Why the egg

The egg in the dough:

• Adds richness
• Tenderizes
• Improves color and crumb

The egg wash on top:

• Glossy brown crust
• Helps seeds adhere

Don't skip either.

Variations

Brioche-style burger buns

Increase butter to 100g, add another egg. Richer, more dessert-like.

Whole wheat burger buns

Replace 200g bread flour with whole wheat. Slightly nuttier.

Slider buns

Same recipe, smaller pieces (60g each). 12–14 mini buns.

Hot dog buns

Same dough, shape as logs (5 inches long).

Pretzel burger buns

Dip in baking soda water before baking (see pretzel recipe).

Onion bun

Top with dried minced onion (or fresh sliced and oiled) before baking.

Storage

Burger buns keep:

• Counter, sealed bag: 3 days (still soft)
• Refrigerated: don't
• Frozen, sliced in half: 2 months

For meal prep, slice in half before freezing for easy toasting.

What makes a great burger bun

The bun is half the burger. A good bun:

• Doesn't fall apart
• Doesn't dominate (let the burger taste through)
• Toasts beautifully
• Holds toppings without getting soggy

A homemade bun makes a backyard burger feel like a restaurant.

Toasting the buns

For best burger:

• Slice buns in half
• Toast cut-side down on a buttered skillet
• 1 minute until golden

The toasted surface keeps the bun from getting soggy from burger juices.

A burger night

Bake buns Saturday morning. By dinner:

• Toasted buns
• Smashed cheeseburgers
• Sliced tomato, lettuce, onion
• Pickles
• Special sauce

A backyard meal that beats most restaurants.

Cost analysis

Sourdough burger buns (8):

• Flour: $1
• Milk, butter, egg, sugar: $1.50
• Total: $2.50

Bakery buns (8): $5–8. Brioche buns (8): $8–12.

Significant savings, much better quality.

A pull-apart variation

For pull-apart slider buns:

• Same dough
• 12 pieces (60g each)
• Place close together in 9x13 pan
• Bake 22 min

Pull apart for sliders.

A breakfast use

Toasted burger bun + egg + bacon + cheese = breakfast sandwich.

Better than McDonald's.

A make-ahead party

For a backyard party:

• Bake buns the day before
• Cool, store in cloth bag
• Slice the day of
• Toast on the grill while burgers cook

The buns stay soft thanks to the milk + butter + egg.

A final tip

Once you've made burger buns from scratch, store-bought feels embarrassing.

The texture is different. The flavor is different. The whole burger experience is elevated.

Bake a batch. Use throughout the week. The next time someone says "I made burger buns," you'll know what they mean.
